ASP.NET MVC button multiple clicks - javascript

ok i have a form on which i have some validation through dataannotation which is client side as well as server side validation like some field already exists. i have no javascript validations on the page. now my problem is that what should i do if the user presses the save button multiple times (he keeps pressing the button for 15 times,in my case the page stays there with field already exist message at the top ) . what do u guys do for that?
what i have done (this works fine in firefox but not in ie) it disable the button no matter what just after click in ie
$(document).ready(function () {
$("#btn").submit(function () {
$('#btn').attr('disabled', 'disabled');
});
});

Put an overlay above the whole page. The overlay prevents the user from clicking twice and gives some feedback. The blockUI plugin does this very well.
EDIT:
$(document).ready(function () {
$("#btn").click(function () {
$('#btn').attr('disabled', 'true'); // Disable the button if you like
$.blockUI(); // Blocking the page with a standard message.
});
});

try using .live or you could hide the button after it is pressed.
$(document).ready(function () {
$("#btn").live("click", function () {
$('#btn').attr('disabled', 'disabled');
//or
$('#btn').hide();
});
});

Javascript or jQuery popup when user click links other than Submit button

I have created a form where user can create his profile, now I want that if user do not click on save/submit button on the page and clicks on any other available link other than save.
Then he should get confirm popup of JavaScript mentioning that you are aborting the creation of profile. I am unable to find any event via which I can achieve this.
Other links are navigation links available on my page.
If you are using button for submit and others as a link then you can find out like this:
$(document).ready(function() {
$(document).('on','click',function(){
var pressedButton = $(this).text();
if(pressedButon == "Submit" || pressedButton =="Save")
{
return false;
}
else
{
$("a").on('click',function() {
var confirmAns = confirm('Your message');
if(confirmAns == true)
{
// DO whatever you want...
}
else
{
//Do whatever you want...
}
});
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
You can use onblur event for it and you can achieve your goal. So when a user click anywhere in your web page then the onblur event automatically fire.
You should use onblur event on your save/submit button.
<button onblur="myFunction()" type="button">Save</button>
<script>
function myFunction() {
var txt;
var r = confirm("You are aborting the creation of profile");
if (r == true) {
return true;
} else {
return false;
}
}
</script>
Try using some plugin. There is one jQuery plugin "Are You Sure"
So you just need below code snippet
$('form').areYouSure();
// OR
$('form.my_form_class').areYouSure();
There are some advanced option available with plugin. Checkout its documentation.
If I understood right, you want this two possibilities:
1.User clicks submit button: form gets submitted
2.User clicks "a" link: get alert asking for confirmation to leave the registration process.
First point will be done automatically as it's a form submit button without the need of extra jQuery.
Second point would just need the following code in order to show the confirmation button:
<script>
$(document).ready(function(){
$('a').on('click',function(e){
if (!confirm("Are you sure you want to exit the registration process?")){
e.preventDefault();
return false;
}
});
});
</script>

Disable submit button on a page when browser back button is clicked

I need to Disable Submit button(s) on the page when browser's back button is clicked. This should be generic meaning in which ever page I place this script, it should disable all the Submit buttons on that page when the user hits the browsers back button.
You should be able to achieve that using window.history.pushState and popstate (See below sample).
For compatibility refer to this
For complete documentation refer to this
jQuery(document).ready(function ($) {
if (window.history && window.history.pushState) {
window.history.pushState('forward', null, null);
$(window).on('popstate', function () {
//Add logic here
});
}
});

Avoid multiple form submit in html

I'm facing a sort of dummy problem.
On my site there is an order form (simple html form) and I noticed that I get double commands from time to time.
I realized that if I clicked repeatedly few times the submit button (before the action page is loaded) I got as many commands as I have clicked.
So I wonder if there are simple solution to make form submission asyncronous?
Thanks
P.S. I added JQuery UI dialog on submit "wait please..." but I get still double commands.
UPDATE
As GeoffAtkins proposed I will:
disable submit after dialog is shown
make use of unique form's token (as it is already added by Symfony) Do not use Symfony token as unique form token as it is always the same for current session. Use just random or something like that.
I would consider doing this (jQuery since you said you used that)
$(function() {
$("#formId").on("submit",function() {
$("#submitBut").hide();
$("#pleaseWait").show();
});
});
if you submit the form and reload the page.
If you Ajax the order, then do
$(function() {
$("#formId").on("submit",function(e) {
e.preventDefault();
var $theForm = $(this);
$("#submitBut").hide();
$("#pleaseWait").show();
$.post($(this).attr("action"),$(this).serialize(),function() {
$theForm.reset();
$("#submitBut").show(); // assuming you want the user to order more stuff
$("#pleaseWait").hide();
});
});
});
NOTE that disabling the submit button on click of the submit button may stop the submission all together (at least in Chrome): https://jsfiddle.net/mplungjan/xc6uc46m/
Just disable the button on click, something like:
$("#my-button-id").on("click", function() {
$(this).attr("disabled", "disabled");
});
var bool = true;
function onclick()
{
if(bool)
{
//do stuff
bool = false;
}
else
{
//ignore
}
}
You could disable the button on the form when it is clicked, and then continue to perform the action. You would probably change the text to say "loading..." or some such.
You may also want to re-enable the button on fail or complete of the ajax request.
I've done this many times similar to this: https://stackoverflow.com/a/19220576/89211

Preventing multiple clicks on button

I have following jQuery code to prevent double clicking a button. It works fine. I am using Page_ClientValidate() to ensure that the double click is prevented only if the page is valid. [If there are validation errors the flag should not be set as there is no postback to server started]
Is there a better method to prevent the second click on the button before the page loads back?
Can we set the flag isOperationInProgress = yesIndicator only if the page is causing a postback to server? Is there a suitable event for it that will be called before the user can click on the button for the second time?
Note: I am looking for a solution that won't require any new API
Note: This question is not a duplicate. Here I am trying to avoid the use of Page_ClientValidate(). Also I am looking for an event where I can move the code so that I need not use Page_ClientValidate()
Note: No ajax involved in my scenario. The ASP.Net form will be submitted to server synchronously. The button click event in javascript is only for preventing double click. The form submission is synchronous using ASP.Net.
Present Code
$(document).ready(function () {
var noIndicator = 'No';
var yesIndicator = 'Yes';
var isOperationInProgress = 'No';
$('.applicationButton').click(function (e) {
// Prevent button from double click
var isPageValid = Page_ClientValidate();
if (isPageValid) {
if (isOperationInProgress == noIndicator) {
isOperationInProgress = yesIndicator;
} else {
e.preventDefault();
}
}
});
});
References:
Validator causes improper behavior for double click check
Whether to use Page_IsValid or Page_ClientValidate() (for Client Side Events)
Note by #Peter Ivan in the above references:
calling Page_ClientValidate() repeatedly may cause the page to be too obtrusive (multiple alerts etc.).
I found this solution that is simple and worked for me:
<form ...>
<input ...>
<button ... onclick="this.disabled=true;this.value='Submitting...'; this.form.submit();">
</form>
This solution was found in:
Original solution
JS provides an easy solution by using the event properties:
$('selector').click(function(event) {
if(!event.detail || event.detail == 1){//activate on first click only to avoid hiding again on multiple clicks
// code here. // It will execute only once on multiple clicks
}
});
disable the button on click, enable it after the operation completes
$(document).ready(function () {
$("#btn").on("click", function() {
$(this).attr("disabled", "disabled");
doWork(); //this method contains your logic
});
});
function doWork() {
alert("doing work");
//actually this function will do something and when processing is done the button is enabled by removing the 'disabled' attribute
//I use setTimeout so you can see the button can only be clicked once, and can't be clicked again while work is being done
setTimeout('$("#btn").removeAttr("disabled")', 1500);
}
working example
I modified the solution by #Kalyani and so far it's been working beautifully!
$('selector').click(function(event) {
if(!event.detail || event.detail == 1){ return true; }
else { return false; }
});
Disable pointer events in the first line of your callback, and then resume them on the last line.
element.on('click', function() {
element.css('pointer-events', 'none');
//do all of your stuff
element.css('pointer-events', 'auto');
};
After hours of searching i fixed it in this way:
old_timestamp = null;
$('#productivity_table').on('click', function(event) {
// code executed at first load
// not working if you press too many clicks, it waits 1 second
if(old_timestamp == null || old_timestamp + 1000 < event.timeStamp)
{
// write the code / slide / fade / whatever
old_timestamp = event.timeStamp;
}
});
you can use jQuery's [one][1] :
.one( events [, data ], handler ) Returns: jQuery
Description: Attach a handler to an event for the elements. The handler is executed at most once per element per event type.
see examples:
using jQuery: https://codepen.io/loicjaouen/pen/RwweLVx
// add an even listener that will run only once
$("#click_here_button").one("click", once_callback);
using count,
clickcount++;
if (clickcount == 1) {}
After coming back again clickcount set to zero.
May be this will help and give the desired functionality :
$('#disable').on('click', function(){
$('#disable').attr("disabled", true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="disable">Disable Me!</button>
<p>Hello</p>
We can use on and off click for preventing Multiple clicks. i tried it to my application and it's working as expected.
$(document).ready(function () {
$("#disable").on('click', function () {
$(this).off('click');
// enter code here
});
})
This should work for you:
$(document).ready(function () {
$('.applicationButton').click(function (e) {
var btn = $(this),
isPageValid = Page_ClientValidate(); // cache state of page validation
if (!isPageValid) {
// page isn't valid, block form submission
e.preventDefault();
}
// disable the button only if the page is valid.
// when the postback returns, the button will be re-enabled by default
btn.prop('disabled', isPageValid);
return isPageValid;
});
});
Please note that you should also take steps server-side to prevent double-posts as not every visitor to your site will be polite enough to visit it with a browser (let alone a JavaScript-enabled browser).
The absolute best way I've found is to immediately disable the button when clicked:
$('#myButton').click(function() {
$('#myButton').prop('disabled', true);
});
And re-enable it when needed, for example:
validation failed
error while processing the form data by the server, then after an error response using jQuery
Another way to avoid a quick double-click is to use the native JavaScript function ondblclick, but in this case it doesn't work if the submit form works through jQuery.
One way you do this is set a counter and if number exceeds the certain number return false.
easy as this.
var mybutton_counter=0;
$("#mybutton").on('click', function(e){
if (mybutton_counter>0){return false;} //you can set the number to any
//your call
mybutton_counter++; //incremental
});
make sure, if statement is on top of your call.
If you are doing a full round-trip post-back, you can just make the button disappear. If there are validation errors, the button will be visible again upon reload of the page.
First set add a style to your button:
<h:commandButton id="SaveBtn" value="Save"
styleClass="hideOnClick"
actionListener="#{someBean.saveAction()}"/>
Then make it hide when clicked.
$(document).ready(function() {
$(".hideOnClick").click(function(e) {
$(e.toElement).hide();
});
});
Just copy paste this code in your script and edit #button1 with your button id and it will resolve your issue.
<script type="text/javascript">
$(document).ready(function(){
$("#button1").submit(function() {
$(this).submit(function() {
return false;
});
return true;
});
});
</script
Plain JavaScript:
Set an attribute to the element being interacted
Remove the attribute after a timeout
If the element has the attribute, do nothing
const throttleInput = document.querySelector('button');
throttleInput.onclick = function() {
if (!throttleInput.hasAttribute('data-prevent-double-click')) {
throttleInput.setAttribute('data-prevent-double-click', true);
throttleInput.setAttribute('disabled', true);
document.body.append("Foo!");
}
setTimeout(function() {
throttleInput.removeAttribute('disabled');
throttleInput.removeAttribute('data-prevent-double-click');
}, 3000);
}
<button>Click to add "Foo"!</button>
We also set the button to .disabled=true. I added the HTML Command input with type hidden to identify if the transaction has been added by the Computer Server to the Database.
Example HTML and PHP Commands:
<button onclick="myAddFunction(<?php echo $value['patient_id'];?>)" id="addButtonId">ADD</button>
<input type="hidden" id="hasPatientInListParam" value="<?php echo $hasPatientInListParamValue;?>">
Example Javascript Command:
function myAddFunction(patientId) {
document.getElementById("addButtonId").disabled=true;
var hasPatientInList = document.getElementById("hasPatientInListParam").value;
if (hasPatientInList) {
alert("Only one (1) patient in each List.");
return;
}
window.location.href = "webAddress/addTransaction/"+patientId; //reloads page
}
After reloading the page, the computer auto-sets the button to .disabled=false. At present, these actions prevent the multiple clicks problem in our case.
I hope these help you too.
Thank you.
One way I found that works is using bootstrap css to display a modal window with a spinner on it. This way nothing in the background can be clicked. Just need to make sure that you hide the modal window again after your long process completes.
so I found a simple solution, hope this helps.
all I had to do was create a counter = 0, and make the function that runs when clicked only runnable if the counter is = 0, when someone clicks the function the first line in the function sets counter = 1 and this will prevent the user from running the function multiple times when the function is done the last line of the code inside the function sets counter to 0 again
you could use a structure like this, it will execute just once:
document.getElementById('buttonID').addEventListener('click', () => {
...Do things...
},{once:true});

Disable then re-enable click function jQuery

I have a file upload system, after the upload button is clicked, the file is then uploaded through AJAX. While the file is uploaded I want to disable the click function that is on the "Select Images" button.
Currently this is the click function on the file-selection button:
$(document).ready(function() {
$("#file-button").click(function() {
$('#file').trigger('click');
});
});
That works fine, but I want to disable the click function in the progress phase of the XmlHttpRequest, and then re-enable the click function when I get a 200 response from the server. I have tried bind() and unbind() and it works fine in Chrome, but in firefox, during the upload, the button cannot be clicked, which is what I want, and then after I get a response from the server the button is re-enabled, but in firefox two file-selection dialogue windows open at the same time. This is because of the function above, and me binding the function again using bind(). Does anyone have any suggestions on how to enable, then disable the button without re-entering the code (function) of the click event.
Something like this would be preferable:
$('#file-button').disable();
$('#file-button').enable();
I have tried the on() and off() and they do not seem to work either.
SOLUTION -- thanks to Eric
I changed my initial click function to the following:
$(document).ready(function() {
$("#file-button").click(function() {
if ( $('#file-button').attr('disabled') == "disabled" ) {
return false;
}
else {
$('#file').trigger('click');
}
});
});
And I set the following to disable the button
$('#file-button').attr('disabled','disabled');
And this to re-enable it:
$('#file-button').removeAttr('disabled');
Disable the button using jQuery $.prop() function:
$("input[type=submit]").prop('disabled', true);
Add a conditional to the click handler to check if the button is disabled:
$("#file-button").click(function() {
if (!$(this).is(':disabled')) {
$('#file').trigger('click');
}
});
Later on re-enable the button:
$("input[type=submit]").prop('disabled', false);
Or you might be able to use the submit event instead of click, if there is a form involved:
$("#whatever-your-form-is").on('submit', function() {
$('#file').trigger('click');
});
Try Attr jQuery function.
$('#file-button').attr('disabled','disabled');
$('#file-button').removeAttr('disabled');
Tested Code
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$("#file-button").click(function(e)
{
e.preventDefault();
$(this).attr('disabled','disabled');
return false;
});
});
</script>
<input type="button" id="file-button" value="ClickMe" />
You have to refer input button in order to disable button ,
Something like below
$("input[type=submit]").prob('disabled', true);
$("inpur[type=submit]").prob('disabled', false);
