jquery question regarding text change - javascript

<script type="text/javascript">
$(function () {
var text3;
$('.HideButton').click(function () {
text3 = $('#MessageText').text;
var theButton = $(this);
$('#disclaimer').slideToggle('slow', function () {
theButton.val($(this).is(':visible') ? 'Hide' : 'Show');
});
$('<p>' + text3 + '</p>').addClass("new").insertAfter('#disclaimer');
return false;
});
});
updated...code above doesnt change the buttons text
<p id="disclaimer" > DDDDDDDDDDDDDDDDDDDDDDDDDD</p>
<asp:Button ID="Button1" CssClass="HideButton" runat="server" Text="Hide" />
I want the text of the button to change each time i press on it..But it doesnt
<p id="disclaimer" >
<input id="MessageText" type="text" />
</p>
<asp:Button ID="Button21" CssClass="HideButton" runat="server" Text="Hide" />
As message typed in the textbox..it should appear while "#disclaimer disappear

The will render out to a form element. This means you should use .val() instead of .text()
Also as Neil has pointed out, you are returning before this gets executed.
$('.HideButton').click(function () {
$('#disclaimer').slideToggle('slow');
// return false;
if ($('#disclaimer').is(':visible')) {
$(this).val('Hide');
} else {
$(this).val('Show');
}
});
});
<p id="disclaimer" > DDDDDDDDDDDDDDDDDDDDDDDDDD</p>
<asp:Button ID="Button1" CssClass="HideButton" runat="server" Text="Hide" />

Thats because you returned before you canged any text.
remove the return ...; (or move it to the end of the function)

Try returning false at the end ;)

Your original question was answered a few different times and a couple different ways. Now you've asked what is essentially a completely new question.
I recommend any further changes be formed into their own questions.
Is this what you now want?
http://jsfiddle.net/kasdega/99GaJ/1/

After return your code will never be executed. Try this
$('.HideButton').click(function () {
var theButton = $(this);
$('#disclaimer').slideToggle('slow', function(){
theButton.val($(this).is(':visible')?'Hide':'Show');
});
return false;
});

Unable to get the value of the clicked button when two button elements shared the same name [duplicate]

I have a .submit() event set up for form submission. I also have multiple forms on the page, but just one here for this example. I'd like to know which submit button was clicked without applying a .click() event to each one.
Here's the setup:
<html>
<head>
<title>jQuery research: forms</title>
<script type='text/javascript' src='../jquery-1.5.2.min.js'></script>
<script type='text/javascript' language='javascript'>
$(document).ready(function(){
$('form[name="testform"]').submit( function(event){ process_form_submission(event); } );
});
function process_form_submission( event ) {
event.preventDefault();
//var target = $(event.target);
var me = event.currentTarget;
var data = me.data.value;
var which_button = '?'; // <-- this is what I want to know
alert( 'data: ' + data + ', button: ' + which_button );
}
</script>
</head>
<body>
<h2>Here's my form:</h2>
<form action='nothing' method='post' name='testform'>
<input type='hidden' name='data' value='blahdatayadda' />
<input type='submit' name='name1' value='value1' />
<input type='submit' name='name2' value='value2' />
</form>
</body>
</html>
Live example on jsfiddle
Besides applying a .click() event on each button, is there a way to determine which submit button was clicked?
I asked this same question: How can I get the button that caused the submit from the form submit event?
I ended up coming up with this solution and it worked pretty well:
$(document).ready(function() {
$("form").submit(function() {
var val = $("input[type=submit][clicked=true]").val();
// DO WORK
});
$("form input[type=submit]").click(function() {
$("input[type=submit]", $(this).parents("form")).removeAttr("clicked");
$(this).attr("clicked", "true");
});
});
In your case with multiple forms you may need to tweak this a bit but it should still apply
I found that this worked.
$(document).ready(function() {
$( "form" ).submit(function () {
// Get the submit button element
var btn = $(this).find("input[type=submit]:focus" );
});
}
This works for me:
$("form").submit(function() {
// Print the value of the button that was clicked
console.log($(document.activeElement).val());
}
When the form is submitted:
document.activeElement will give you the submit button that was clicked.
document.activeElement.getAttribute('value') will give you that button's value.
Note that if the form is submitted by hitting the Enter key, then document.activeElement will be whichever form input that was focused at the time. If this wasn't a submit button then in this case it may be that there is no "button that was clicked."
There is a native property, submitter, on the SubmitEvent interface.
Standard Web API:
var btnClicked = event.submitter;
jQuery:
var btnClicked = event.originalEvent.submitter;
Here's the approach that seems cleaner for my purposes.
First, for any and all forms:
$('form').click(function(event) {
$(this).data('clicked',$(event.target))
});
When this click event is fired for a form, it simply records the originating target (available in the event object) to be accessed later. This is a pretty broad stroke, as it will fire for any click anywhere on the form. Optimization comments are welcome, but I suspect it will never cause noticeable issues.
Then, in $('form').submit(), you can inquire what was last clicked, with something like
if ($(this).data('clicked').is('[name=no_ajax]')) xhr.abort();
Wow, some solutions can get complicated! If you don't mind using a simple global, just take advantage of the fact that the input button click event fires first. One could further filter the $('input') selector for one of many forms by using $('#myForm input').
$(document).ready(function(){
var clkBtn = "";
$('input[type="submit"]').click(function(evt) {
clkBtn = evt.target.id;
});
$("#myForm").submit(function(evt) {
var btnID = clkBtn;
alert("form submitted; button id=" + btnID);
});
});
I have found the best solution is
$(document.activeElement).attr('id')
This not only works on inputs, but it also works on button tags.
Also it gets the id of the button.
Another possible solution is to add a hidden field in your form:
<input type="hidden" id="btaction"/>
Then in the ready function add functions to record what key was pressed:
$('form#myForm #btnSubmit').click(function() {
$('form#myForm #btaction').val(0);
});
$('form#myForm #btnSubmitAndSend').click(function() {
$('form#myForm #btaction').val(1);
});
$('form#myForm #btnDelete').click(function() {
$('form#myForm #btaction').val(2);
});
Now in the form submition handler read the hidden variable and decide based on it:
var act = $('form#myForm #btaction').val();
Building on what Stan and yann-h did but this one defaults to the first button. The beauty of this overall approach is that it picks up both the click and the enter key (even if the focus was not on the button. If you need to allow enter in the form, then just respond to this when a button is focused (i.e. Stan's answer). In my case, I wanted to allow enter to submit the form even if the user's current focus was on the text box.
I was also using a 'name' attribute rather than 'id' but this is the same approach.
var pressedButtonName =
typeof $(":input[type=submit]:focus")[0] === "undefined" ?
$(":input[type=submit]:first")[0].name :
$(":input[type=submit]:focus")[0].name;
This one worked for me
$('#Form').submit(function(){
var btn= $(this).find("input[type=submit]:focus").val();
alert('you have clicked '+ btn);
}
Here is my solution:
$('#form').submit(function(e){
console.log($('#'+e.originalEvent.submitter.id));
e.preventDefault();
});
If what you mean by not adding a .click event is that you don't want to have separate handlers for those events, you could handle all clicks (submits) in one function:
$(document).ready(function(){
$('input[type="submit"]').click( function(event){ process_form_submission(event); } );
});
function process_form_submission( event ) {
event.preventDefault();
//var target = $(event.target);
var input = $(event.currentTarget);
var which_button = event.currentTarget.value;
var data = input.parents("form")[0].data.value;
// var which_button = '?'; // <-- this is what I want to know
alert( 'data: ' + data + ', button: ' + which_button );
}
As I can't comment on the accepted answer, I bring here a modified version that should take into account elements that are outside the form (ie: attached to the form using the form attribute). This is for modern browser: http://caniuse.com/#feat=form-attribute . The closest('form') is used as a fallback for unsupported form attribute
$(document).on('click', '[type=submit]', function() {
var form = $(this).prop('form') || $(this).closest('form')[0];
$(form.elements).filter('[type=submit]').removeAttr('clicked')
$(this).attr('clicked', true);
});
$('form').on('submit', function() {
var submitter = $(this.elements).filter('[clicked]');
})
You can simply get the event object when you submit the form. From that, get the submitter object. As below:
$(".review-form").submit(function (e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
let submitter_btn = $(e.originalEvent.submitter);
console.log(submitter_btn.attr("name"));
}
In case you want to send this form to the backend, you can create a new form element by new FormData() and set the key-value pair for which button was pressed, then access it in the backend. Something like this -
$(".review-form").submit(function (e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
let form = $(this);
let newForm = new FormData($(form)[0]);
let submitter_btn = $(e.originalEvent.submitter);
console.log(submitter_btn.attr("name"));
if (submitter_btn.attr("name") == "approve_btn") {
newForm.set("action_for", submitter_btn.attr("name"));
} else if (submitter_btn.attr("name") == "reject_btn") {
newForm.set("action_for", submitter_btn.attr("name"));
} else {
console.log("there is some error!");
return;
}
}
I was basically trying to have a form where user can either approve or disapprove/ reject a product for further processes in a task.
My HTML form is something like this -
<form method="POST" action="{% url 'tasks:review-task' taskid=product.task_id.id %}"
class="review-form">
{% csrf_token %}
<input type="hidden" name="product_id" value="{{product.product_id}}" />
<input type="hidden" name="task_id" value="{{product.task_id_id}}" />
<button type="submit" name="approve_btn" class="btn btn-link" id="approve-btn">
<i class="fa fa-check" style="color: rgb(63, 245, 63);"></i>
</button>
<button type="submit" name="reject_btn" class="btn btn-link" id="reject-btn">
<i class="fa fa-times" style="color: red;"></i>
</button>
</form>
Let me know if you have any doubts.
Try this:
$(document).ready(function(){
$('form[name="testform"]').submit( function(event){
// This is the ID of the clicked button
var clicked_button_id = event.originalEvent.submitter.id;
});
});
$("form input[type=submit]").click(function() {
$("<input />")
.attr('type', 'hidden')
.attr('name', $(this).attr('name'))
.attr('value', $(this).attr('value'))
.appendTo(this)
});
add hidden field
For me, the best solutions was this:
$(form).submit(function(e){
// Get the button that was clicked
var submit = $(this.id).context.activeElement;
// You can get its name like this
alert(submit.name)
// You can get its attributes like this too
alert($(submit).attr('class'))
});
Working with this excellent answer, you can check the active element (the button), append a hidden input to the form, and optionally remove it at the end of the submit handler.
$('form.form-js').submit(function(event){
var frm = $(this);
var btn = $(document.activeElement);
if(
btn.length &&
frm.has(btn) &&
btn.is('button[type="submit"], input[type="submit"], input[type="image"]') &&
btn.is('[name]')
){
frm.append('<input type="hidden" id="form-js-temp" name="' + btn.attr('name') + '" value="' + btn.val() + '">');
}
// Handle the form submit here
$('#form-js-temp').remove();
});
Side note: I personally add the class form-js on all forms that are submitted via JavaScript.
Similar to Stan answer but :
if you have more than one button, you have to get only the
first button => [0]
if the form can be submitted with the enter key, you have to manage a default => myDefaultButtonId
$(document).on('submit', function(event) {
event.preventDefault();
var pressedButtonId =
typeof $(":input[type=submit]:focus")[0] === "undefined" ?
"myDefaultButtonId" :
$(":input[type=submit]:focus")[0].id;
...
}
This is the solution used by me and work very well:
// prevent enter key on some elements to prevent to submit the form
function stopRKey(evt) {
evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
var alloved_enter_on_type = ['textarea'];
if ((evt.keyCode == 13) && ((node.id == "") || ($.inArray(node.type, alloved_enter_on_type) < 0))) {
return false;
}
}
$(document).ready(function() {
document.onkeypress = stopRKey;
// catch the id of submit button and store-it to the form
$("form").each(function() {
var that = $(this);
// define context and reference
/* for each of the submit-inputs - in each of the forms on
the page - assign click and keypress event */
$("input:submit,button", that).bind("click keypress", function(e) {
// store the id of the submit-input on it's enclosing form
that.data("callerid", this.id);
});
});
$("#form1").submit(function(e) {
var origin_id = $(e.target).data("callerid");
alert(origin_id);
e.preventDefault();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="form1" name="form1" action="" method="post">
<input type="text" name="text1" />
<input type="submit" id="button1" value="Submit1" name="button1" />
<button type="submit" id="button2" name="button2">
Submit2
</button>
<input type="submit" id="button3" value="Submit3" name="button3" />
</form>
This works for me to get the active button
var val = document.activeElement.textContent;

Form submited only after submit button was clicked.
var theBtn = $(':focus');
if(theBtn.is(':submit'))
{
// ....
return true;
}
return false;
I was able to use jQuery originalEvent.submitter on Chrome with an ASP.Net Core web app:
My .cshtml form:
<div class="form-group" id="buttons_grp">
<button type="submit" name="submitButton" value="Approve" class="btn btn-success">Approve</button>
<button type="submit" name="submitButton" value="Reject" class="btn btn-danger">Reject</button>
<button type="submit" name="submitButton" value="Save" class="btn btn-primary">Save</button>
...
The jQuery submit handler:
#section Scripts {
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script type="text/javascript">
$(document).ready(function() {
...
// Ensure that we log an explanatory comment if "Reject"
$('#update_task_form').on('submit', function (e) {
let text = e.originalEvent.submitter.textContent;
if (text == "Reject") {
// Do stuff...
}
});
...
The jQuery Microsoft bundled with my ASP.Net Core environment is v3.3.1.
Let's say I have these "submit" buttons:
<button type="submit" name="submitButton" id="update" value="UpdateRecord" class="btn btn-primary">Update Record</button>
<button type="submit" name="submitButton" id="review_info" value="ReviewInfo" class="btn btn-warning sme_only">Review Info</button>
<button type="submit" name="submitButton" id="need_more_info" value="NeedMoreInfo" class="btn btn-warning sme_only">Need More Info</button>
And this "submit" event handler:
$('#my_form').on('submit', function (e) {
let x1 = $(this).find("input[type=submit]:focus");
let x2 = e.originalEvent.submitter.textContent;
Either expression works. If I click the first button, both "x1" and "x2" return Update Record.
I also made a solution, and it works quite well:
It uses jQuery and CSS
First, I made a quick CSS class, this can be embedded or in a seperate file.
<style type='text/css'>
.Clicked {
/*No Attributes*/
}
</style>
Next, On the click event of a button within the form,add the CSS class to the button. If the button already has the CSS class, remove it. (We don't want two CSS classes [Just in case]).
// Adds a CSS Class to the Button That Has Been Clicked.
$("form :input[type='submit']").click(function ()
{
if ($(this).hasClass("Clicked"))
{
$(this).removeClass("Clicked");
}
$(this).addClass("Clicked");
});
Now, test the button to see it has the CSS class, if the tested button doesn't have the CSS, then the other button will.
// On Form Submit
$("form").submit(function ()
{
// Test Which Button Has the Class
if ($("input[name='name1']").hasClass("Clicked"))
{
// Button 'name1' has been clicked.
}
else
{
// Button 'name2' has been clicked.
}
});
Hope this helps!
Cheers!
You can create input type="hidden" as holder for a button id information.
<input type="hidden" name="button" id="button">
<input type="submit" onClick="document.form_name.button.value = 1;" value="Do something" name="do_something">
In this case form passes value "1" (id of your button) on submit. This works if onClick occurs before submit (?), what I am not sure if it is always true.
A simple way to distinguish which <button> or <input type="button"...> is pressed, is by checking their 'id':
$("button").click(function() {
var id = $(this).attr('id');
...
});
Here is a sample, that uses this.form to get the correct form the submit is into, and data fields to store the last clicked/focused element. I also wrapped submit code inside a timeout to be sure click events happen before it is executed (some users reported in comments that on Chrome sometimes a click event is fired after a submit).
Works when navigating both with keys and with mouse/fingers without counting on browsers to send a click event on RETURN key (doesn't hurt though), I added an event handler for focus events for buttons and fields.
You might add buttons of type="submit" to the items that save themselves when clicked.
In the demo I set a red border to show the selected item and an alert that shows name and value/label.
Here is the FIDDLE
And here is the (same) code:
Javascript:
$("form").submit(function(e) {
e.preventDefault();
// Use this for rare/buggy cases when click event is sent after submit
setTimeout(function() {
var $this=$(this);
var lastFocus = $this.data("lastFocus");
var $defaultSubmit=null;
if(lastFocus) $defaultSubmit=$(lastFocus);
if(!$defaultSubmit || !$defaultSubmit.is("input[type=submit]")) {
// If for some reason we don't have a submit, find one (the first)
$defaultSubmit=$(this).find("input[type=submit]").first();
}
if($defaultSubmit) {
var submitName=$defaultSubmit.attr("name");
var submitLabel=$defaultSubmit.val();
// Just a demo, set hilite and alert
doSomethingWith($defaultSubmit);
setTimeout(function() {alert("Submitted "+submitName+": '"+submitLabel+"'")},1000);
} else {
// There were no submit in the form
}
}.bind(this),0);
});
$("form input").focus(function() {
$(this.form).data("lastFocus", this);
});
$("form input").click(function() {
$(this.form).data("lastFocus", this);
});
// Just a demo, setting hilite
function doSomethingWith($aSelectedEl) {
$aSelectedEl.css({"border":"4px solid red"});
setTimeout(function() { $aSelectedEl.removeAttr("style"); },1000);
}
DUMMY HTML:
<form>
<input type="text" name="testtextortexttest" value="Whatever you write, sir."/>
<input type="text" name="moretesttextormoretexttest" value="Whatever you write, again, sir."/>
<input type="submit" name="test1" value="Action 1"/>
<input type="submit" name="test2" value="Action 2"/>
<input type="submit" name="test3" value="Action 3"/>
<input type="submit" name="test4" value="Action 4"/>
<input type="submit" name="test5" value="Action 5"/>
</form>
DUMB CSS:
input {display:block}
I write this function that helps me
var PupulateFormData= function (elem) {
var arr = {};
$(elem).find("input[name],select[name],button[name]:focus,input[type='submit']:focus").each(function () {
arr[$(this).attr("name")] = $(this).val();
});
return arr;
};
and then Use
var data= PupulateFormData($("form"));

Update one textbox using javascript function when another changes

I have a javascript function that counts characters in 2 different textboxes and puts the value in a third textbox.
This is the function is as follows:
function CountChars() {
var subjectLength = document.getElementById("txtBoxSubject").value.length;
var msgLength = document.getElementById("txtBoxMsg").value.length;
document.getElementById("txtBoxCnt").value = subjectLength + msgLength;
}
I call it from the Message text box using 'onkeyup' and it works fine.
<asp:TextBox ID="txtBoxMsg" runat="server" ClientIDMode="Static"
TextMode="MultiLine" onkeyup="CountChars()"></asp:TextBox>
The Subject textbox can be changed using a dropdown list or a user adding text to it. So using 'onkeyup' will not work for the Subject textbox. I tried using 'onchange' and nothing is entered in the Count text box.
This is the Subject html:
<asp:TextBox ID="txtBoxSubject" runat="server" ClientIDMode="Static" onchange="CountChars()"></asp:TextBox>
What am I doing wrong?
How can I call the javascript function whenver the text changes in the Subject textbox?
Thanks.
UPDATE
This is the Subject dropdown and the function that is called when it changes.
<asp:DropDownList ID="ddListSubject" runat="server" ClientIDMode="Static" AutoPostBack="true" onchange="SubjectChanged();">
</asp:DropDownList>
function SubjectChanged() {
var strSubject = document.getElementById("ddListSubject").value;
if (strSubject == "Custom") {
document.getElementById("txtBoxSubject").value = "";
document.getElementById("txtBoxSubject").focus();
}
else {
document.getElementById("txtBoxSubject").value = strSubject;
}
CountChars(); //number appears for a second then disappears
}
it seems like you not terminating the function with semi column. use something like onkeyup="CountChars();"
Your .aspx are using MasterPage? The names of Asp.Net objects changing in the rendered page. Try using <% =% Objeto.ClientID>.
function CountChars() {
var subjectLength = document.getElementById("<%=txtBoxSubject.ClientID %>").value.length;
var msgLength = document.getElementById("<%= txtBoxMsg.ClientID %>").value.length;
document.getElementById("<%= txtBoxCnt.ClientID %>").value = subjectLength + msgLength;
}
Or maybe use JQuery. Look at the code below, works as you described.
Subject:
<input id="text1" type="text" />
<br />
Msg
<input id="text2" type="text" multiple style="height: 100px" />
<br />
Total: <span id="total">0</span>
<script type="text/javascript">
$(document).ready(function () {
$("input[type=text]").keyup(function () {
var total = 0;
$("input[type=text]").each(function () {
total += $(this).val().length;
});
$("#total").html(total);
});
});
</script>
Hope this helps you
Dummy me...I removed the AutoPostBack="true" from the Dropdown!
Thanks for all of your help!!

How identify the form submit button clicked in a variable using Jquery

How can I assign the id of a submit button to a variable using JQuery?
I have the following HTML:
<form id="myForm">
<input id="oknovo" type="submit" value="OK & Novo" />
<input id="okfechar" type="submit" value="OK & Fechar" />
</form>
JS:
var botao;
$(document).ready(function () {
$("#myForm input[type=submit]").click(function (event) {
botao = $(this).attr('id');
alert("id é " + botao);
});
});
You may see the live JSFiddle here
I've already managed to indentify the clicked button wiht the help of this question but the problem now is to assign it to a global variable.
Your code is correct, you just need to add the closing parenthesis ) at the end.
$(document).ready(function () {
^ unclosed
the problem now is to assign it to a global variable.
Either remove the line var botao; or take it out of the function you are calling onload (via the JSFiddle configuration on the left).
You are missing brackets on your fiddle. It should read:
var botao;
$(document).ready(function () {
$("#myForm input[type=submit]").click(function (event) {
botao = $(this).attr('id');
alert("id é " + botao);
});
});
This question does not makes any sense, since code looks like working except syntax errors; on the other hand, you can use hidden fields to keep some data for temporary.
<form id="myForm">
<input id='myGlobalHidden' type='hidden'/>
<input id="oknovo" type="button" value="OK & Novo" />
<input id="okfechar" type="button" value="OK & Fechar" />
</form>
var botao;
$(document).ready(function () {
$("#myForm input[type=button]").click(function (event) {
botao = $(this).attr('id');
//alert("id é " + botao);
$("#myGlobalHidden").val(botao);
// access here
alert($("#myGlobalHidden").val());
});
});

MooTools: How can I replace existing field text with text insert?

I've been on this one for a while but no luck so far, however I did get emoticons fully working using code for mootools.
Basically, I have a existing field of
<input type="text" class="post_action_input" value="Say Something..." id="emoticons_insert" />
And a image underneath containing
<img onClick="javascript:$('blove2').fancyShow();" src="./images/user_status_emoticon.jpg" width="25" height="25" />
Which triggers a dropdown containing this emoticon DIV that inserts the :alien: text into the field above
<div id="blove2"><img src="./images/smiley/alien.png" alt="" onClick="javascript:$('blove2').fancyHide();" /></div>
<div id="emoticon1" style="display:none;"> :alien: </div>
And it works great. However, what is really messing up our users is that our input field contains "Say Something" that dissapeares upon click, reappears on outer click etc. When they click the emoticon, it appends and produces "Say Something...:alien:" and posts just like that. How can I completely clear "Say Something..." while preserving the :alien: text upon clicking a emoticon? We are using MooTools 1.2.
Field insert Javascript:
<script type="text/javascript">
function get(id) {
return document.getElementById(id);
}
function contentHTML(id, m) {
var obj = get(id),
op = '';
if (m) {
op += obj.innerHTML;
} else if (!m) {
op += (!obj.innerText) ? obj.textContent : obj.innerText;
}
return (op);
}
function InsertText(input, output) {
var text = contentHTML(input, true);
var ele = get(output);
ele.value += text;
}
</script>
Emoticons drop-down JavaScript:
<script type="text/javascript">
window.addEvent('domready', function() {
Element.implement({
fancyShow: function() {
this.fade('in');
this.setStyle('display', '');
},
fancyHide: function() {
this.fade('out');
this.setStyle('display', 'none');

//$('element').fancyHide(); // FREEZES STATUS INPUT FIELD FOR SOME REASON
});
</script>
In other words, how can onClick insert replace "Say Something..." from the field, and insert :alien: successfully? Thank you very much guys!
Here is a suggestion, with less code.
In this suggestion I use Mootools's OverText, instead of your inline onfocus/onclick/onblur/value which will not work. OverText comes with Mootools More and in the fiddle I used mootools 1.3.
HTML
<input type="text" class="post_action_input" title="Say something..." id="emoticons_insert" />
<img onClick="javascript:$('blove2').fancyShow();" src="/images/user_status_emoticon.jpg" width="25" height="25" />
<div id="blove2">
<img src="/images/smiley/alien.png" data-name=":alien:" class="emoticon" alt="" />
</div>
Mootools
function InsertText(input, output) {
var ele = document.id(output);
ele.value += input;
ele.fireEvent('change');
}
window.addEvent('domready', function () {
Element.implement({
fancyShow: function () {
this.fade('in');
this.setStyle('display', '');
},
fancyHide: function () {
this.fade('out');
this.setStyle('display', 'none');
}
});
// Labels over the inputs.
document.getElements('input').each(function (el) {
new OverText(el);
});
document.getElements('.emoticon').addEvent('click', function () {
var icon_name = this.get('data-name');
InsertText(icon_name, 'emoticons_insert');
this.getParent().fancyHide();
});
});

How to disable a linkbutton to prevent multiple submits

I have HTML code like this:
<asp:LinkButton ID="AddButton" runat="server" OnClick="AddPatientBtn_Click">
<span class="Normal">Add</span>
</asp:LinkButton>
I find if we click 'Add' several times, it will add several patient records, so I want to change the code like this:
<asp:LinkButton ID="AddButton" runat="server" OnClick="AddPatientBtn_Click" OnClientClick="return DisableButton(this)">
<span class="Normal">Add</span>
</asp:LinkButton>
js:
function DisableButton(button) {
document.all("AddButton").click;
button.href = "javascript:void(0);";
button.setAttribute("disabled", "disabled");
}
But this doesn't work; I can still add many patient records.
What should I do?
Thanks for all of you!
I find that LinkButton may not have the disable attribute, it is a <a> in html page.
so I use another solution
<asp:LinkButton ID="AddButton" runat="server" OnClick="AddPatientBtn_Click" OnClientClick="return DisableButton()">
<span class="Normal">Add</span>
</asp:LinkButton>
js:
var pending = false;
function DisableButton() {if (pending) {
alert("The new patient is being created. Please wait...");
return false;
}
else {
if (Page_ClientValidate(""))
pending = true;
return true;
}
}
You can just say
AddButton.Enabled = false;
in the code behind page
or you can write
document.getElementById("AddButton").disabled = true;
var button = document.getElementById("AddButton");
button.setAttribute("disabled", "true");
