I have a site built via flask that takes the information provided by the user and performs some action . I also have a loader that shows up when this action is done in the background, the trouble is , if the user were to click on the button "process" without filling the details , the loader is still shown .
How do i make the loader appear only when all the input fields are entered by the user and then clicks on "process" button
<form action="/result" method="post">
<tbody>
<tr>
<td><input type='text' name="ip" id='ipadd' required="required" placeholder="8.8.8.8" pattern="((^|\.)((25[0-5])|(2[0-4]\d)|(1\d\d)|([1-9]?\d))){4}$" value style="margin-bottom: 5px;" autocomplete="off"></td>
</tr>
</tbody>
</table>
<button class="btn btn-outline btn-success" style="padding-right: 15pt;"onclick="loading();">Process</button>
</form>
<script type="text/javascript">// <![CDATA[
function loading(){
$("#loading").show();
$("#content").hide();
}
// ]]></script>
Since your field is required you could hide or disable the button if the form is :invalid via CSS, e.g.
form:invalid button {
pointer-events: none;
opacity: .4;
}
<form>
<input type='text' name="ip" id='ipadd' required="required"
placeholder="8.8.8.8"
pattern="((^|\.)((25[0-5])|(2[0-4]\d)|(1\d\d)|([1-9]?\d))){4}$" />
<button>Send</button>
</form>
do a check that if input field is empty then return else execute your api call/loader, or disable your process button till value is null

I would like to show the second text field incl. copy button as soon as i submit the the first text field. how i can hide the second text field and show after submit?
I tried as following:
HTML:
First Texfield:
<tr><td><input type="text" id="source">
<button type="submit" id="submit" id="formButton">Submit</button></td></tr>
Second Textfield:
<tr><td><input type="text" size="62" id="target" id="form1">
<button onClick="myFunct()" id="form1">Copy</button></td></tr>
JQuery:
<script>
$("#formButton").click(function(){
$("#form1").toggle();
});
</script>
Thank you so much for your support.
If you intend to submit data to a server normally you should have your inputs and buttons wrapped in a <form> tag, so I added one and set it up so that it sends to a live test server. There's also an iframe added as well to display the server's response. The jQuery is simple:
$('#main').on('submit', function() {...
When form#main "hears" a submit event (i.e. when the button[type=submit] is clicked...
$('.row2').removeClass('hide');
...Remove the class .hide form tr.row2 which removes the style display:none
BTW, ids must be unique. #form1 is duplicated and there's 2 ids on one button in OP code.
Demo
$("#main").on('submit', function() {
$(".row2").removeClass('hide');
});
.hide {
display: none
}
<form id='main' action='https://httpbin.org/post' method='post' target='view'>
<table>
<tr>
<td><input type="text" id="source" name='source'>
<button type="submit">Submit</button></td>
</tr>
<tr class='row2 hide'>
<td><input type="text" size="62" id="target" name='target'>
<button type='button'>Copy</button></td>
</tr>
</table>
</form>
<iframe name='view'></iframe>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
The first problem is that you have duplicate IDs on the button (both submit and formButton). An element can only have one ID. I've gone with the latter in my example.
Second, you have duplicate form1 IDs, which is also invalid markup. Simply make use of classes instead.
Then it's just a matter of hiding these elements by default, and showing them on click of the button. I'd recommend .show() for this instead of .toggle().
This can be seen in the following:
$("#formButton").click(function() {
$(".form1").show();
});
.form1 {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<tr>
<td>
<input type="text" id="source">
<button type="submit" id="formButton">Submit</button>
</td>
</tr>
<tr>
<td>
<input type="text" size="62" id="target" class="form1">
<button onClick="myFunct()" class="form1">Copy</button>
</td>
</tr>
I have a form on my page and want to be able to submit the text box value (partnumber) as a query string in a hyperlink without submitting the form itself ? Is this possible ?
I have done some research and have tried document.getElementById("partnumber").value but am getting the error "Object Required". Code Below.
<form id="form3" name="form3" method="post" action="formpost?rmaid=<%=rmaid%>">
<input name="partnumber" type="text" id="partnumber" size="10" />
<span class="style11">Suggest Link</span>
<input name="invoice" type="text" id="invoice" size="15" />
</form>
I'll set the new page to open in a pop up window and list a series of values in the database but then I need the value selected to come back into the invoice field on the original page. I believe this can be done with JavaScript but I am new to this, can anyone help ?
For those Looking to pass values back I have found this snippet that works...
Put this in the child window
<script language="javascript">
function changeParent() {
window.opener.document.getElementById('Invoice').value="Value changed..";
window.close();
}
</script>
<form>
<input type=button onclick="javascript:changeParent()" value="Change opener's textbox's value..">
</form>
For the input field you should add an OnChange to it. This event should call a function which will then set your link's value.
You can see an example of this here (it uses a button press though and not an input OnChange Event): http://www.java2s.com/Code/JavaScript/HTML/ChangeURLandtextofahyperlink.htm
Edit: Added a Stack Snippet illustrating the solution.
function SetSuggestLink() {
var suggest = document.getElementById('partnumber').value;
document.getElementById('innerSpan').innerHTML =
"Suggest Link: suggest.asp?partnumber=" + suggest;
document.getElementById('QueryLink').href =
"suggest.asp?partnumber=" + suggest;
}
.style11 {
color:black;
}
.style2 {
text-decoration:none;
}
<form id="form3" name="form3" method="post" action="formpost?rmaid=SomeValue">
<input name="partnumber" type="text" id="partnumber" size="10"
OnChange="SetSuggestLink()" /> </br>
<a id="QueryLink" class="style2" href="#">
<span id="innerSpan" class="style11">Suggest Link</span>
</a></br>
<input name="invoice" type="text" id="invoice" size="15" />
</form>
When I click on submit1 and then on submit2 everything is going well, but, when I press Enter Key on 1st input text I go to the second part
When I press Enter Key on the 2nd input text -> 1st JavaScript function executes which causes me trouble.
I don't want to disable Enter Key press, but that he executes the good submit input.
Is there a way to deactivate submit1 after he has been executed?
Or know from which input text Enter Key has been pressed?
HTML:
<div id="1">
<input type="text" placeholder="name"/>
</div>
<div id="2">
<input type="submit" value="submit" id="submit1"/>
</div>
<div id="3">
<input type="text" placeholder="firstname"/>
</div>
<div id="4">
<input type="submit" value="submit" id="submit2"/>
</div>
CSS:
#3, #4
{
display: none;
}
JavaScript:
$(document).ready(function() {
$("#submit1").click(function () {
/* Verify data with javascript and send it with Ajax */
/* if everything is ok display: */
document.querySelector("#2").style.display = "none";
document.querySelector("#3").style.display = "block";
document.querySelector("#4").style.display = "block";
});
$("#submit2").click(function () {
/* Verify data with javascript and send it with Ajax */
});
});
Unless I misunderstood the question - you are simply trying to make sure that the correct event handler gets called based on which button is selected by the user. This will work fine as long as the buttons have unique IDs which they do - and you can associate them with the correct event handler (which it seems like you are doing in the shared code).
Also, you can disable any button using the disabled attribute (set it to true).
to disable
document.getElementById("submit1").disabled = true;
to enable:
document.getElementById("submit1").disabled = false;
From what I can tell your biggest problem here is that you seem to have two submit buttons in a single form tag. I would seriously recommend against this as it can cause issues like the one you are experiencing. Instead I would change both to buttons and add the submit functionality to JavaScript methods as you are kind of doing now.
Obviously though you would want to link the text boxes to a button then and for that I would take a look at this SO question How to trigger HTML button when you press Enter in textbox?
<input type="submit"> is a special control. It will cause the form to submit if the form has focus and the enter button is pressed. When using this you should make use of event.preventDefault() to cancel that behavior when binding to the click event. I suggest using <button type="button"><button> instead.
If you press ENTER on submit1, submit2 will not be selected unless you hit TAB. Are you doing this?
Anyway, you can do this:
$("#submit1").click(function () {
/* Verify data with javascript and send it with Ajax */
/* if everything is ok display: */
$("#submit2").focus(); // This will automatically focus the user on the second submit button //
});
This will force the user, the next time he hits ENTER, to submit the submit2 button.
But don't use .submit()... you should use the .submit() function instead of .click(), because I believe .click() only checks for mouse clicks?
$("#submit1").submit(function(){
/* Blah blah blah... */
$("#submit2").focus(); // This will automatically focus the user on the second submit button //
});
$("#submit2").submit(function(){
/* ... */
});
As other users have said, are submit1 and submit2 in the same <form> tag:
Yes, they were. But you shouldn't have 2 fields in the same <form> tag if you want to submit the data separately.
Do this:
HTML
<form>
<div id="1">
<input type="text" placeholder="name"/>
</div>
<div id="2">
<input type="submit" value="submit" id="submit1"/>
</div>
</form>
<form>
<div id="3">
<input type="text" placeholder="firstname"/>
</div>
<div id="4">
<input type="submit" value="submit" id="submit2"/>
</div>
</form>
JQuery
$("#submit1").submit(function(e){
/* Blah blah blah... */
e.preventDefault(); // Keeps the user on the same page //
});
$("#submit2").submit(function(e){
/* ... */
e.preventDefault(); // Keeps the user on the same page //
});
I let it work like that:
Why should I have troubles with one form? IE < 6?
HTML:
<form>
<div id="1">
<input type="text" id="text1"/>
</div>
<div id="2">
<input type="submit" value="submit" id="submit1"/>
</div>
<div id="3">
<input type="text" id="text2"/>
</div>
<div id="4">
<input type="submit" value="submit" id="submit2"/>
</div>
</form>
CSS:
#3, #4
{
display: none;
}
JAVASCRIPT:
$(document).ready(function() {
$('#text2').keypress(function(e){
if(e.keyCode==13)
$('#submit2').click();
});
$("#submit1").click(function () {
/* Verify data with javascript and send it with Ajax */
/* if everything is ok display: */
document.querySelector("#2").style.display = "none";
document.querySelector("#3").style.display = "block";
document.querySelector("#4").style.display = "block";
document.querySelector("#submit1").disabled = true;
});
$("#submit2").click(function () {
/* Verify data with javascript and send it with Ajax */
});
});
I am creating a form such that when the user click the "submit" button, it prevents the default action, serializes a subset of the fields, and then proceeds to submit all of the information via the POST array (PHP).
I am encountering a problem where the form is basically not submitting when I use the .submit() method. When I disable my javascript, the form submits fine (just with the wrong information, as the array is not serialized). But as soon as I re-enable my js, clicking the submit button does nothing except show my test console.log(var) in console. Here is some of my code, hopefully you can see what I am doing wrong. All of the online documentation says to use .submit(), but it doesn't seem to work, no matter what I try.
HTML:
<form id="entryForm" action="add_entry.php" method="post">
<div class="leftDiv">
<input type="text" class="inputFormTitle" name="entryName" placeholder="Name your entry..." />
<span class="regText">
<b>Entry Properties</b>
Specify entry properties, permissions, etc.</span>
<table class="formTable">
<tr>
<th>Parameter</th>
<th>Value</th>
<tr>
<td>Group</td>
<td><select name="group"><option></option><option>Graham Test</option></select>
</tr>
<tr>
<td>Project</td>
<td><select name="project"><option></option><option>Project 1</option><option>Project 2</option></select>
</tr>
<tr>
<td>Protocol</td>
<td>
<select id="protocolloader" name="protocol">
<option></option>
<option>PCR & Gel</option>
<option>Item Storage</option>
<tr>
<td>Permissions</td>
<td><input type="radio" name="permission" value="0">Only I can access this entry</input>
<input type="radio" name="permission" value="1">Only group members can access this entry</input>
<input type="radio" name="permission" value="2">Everyone can access this entry</input>
</select>
</tr>
</table>
<input type="submit" id="submitEntry" style="font-family:Raleway;" class="inputButton" type="button" name="submit" value="Submit Entry" /
<br/>
</div>
<div class="rightDiv">
<input type="text" class="inputFormTitle" id="ppt" placeholder="Please select a protocol" disabled/>
<div class="formHolder" id="protocolForm">
</div>
</div>
<input type="hidden" id="serialInput" name="protocolValues" value="nuttin" />
</form>
And the accompanying javascript:
var entrySubmit = $('#submitEntry');
entrySubmit.on('click', initEntrySubmission);
function initEntrySubmission(e) {
e.preventDefault();
var serializedProtocol = $("#protocolForm :input").serialize();
console.log(serializedProtocol);
$('#serialInput').val(serializedProtocol);
$('#entryForm').submit();
}
PHP Form (which I don't think is the issue but figured I would include it anyways)
<?php // add_entry.php
session_start();
include_once 'creds.php';
$con=mysqli_connect("$db_hostname","$db_username","$db_password","$db_database");
if (isset($_POST['group'])){
$lab = $_SESSION['labname'];
$author = $_SESSION['username'];
$name = $_POST['entryName'];
$group = $_POST['group'];
$protocol = $_POST['protocol'];
$permission = $_POST['permission'];
$array = $_POST['serialInput'];
$filearray = $_POST['fileArray'];
$project = $_POST['project'];
$query = "INSERT INTO data (protocol, name, lab, author, uniquearray, filearray, group, project, permissionflag)
VALUES ('$protocol', '$name', '$lab', '$author', '$array', '$filearray', '$group', 'project', '$permission')";
mysqli_query($con, $query);
mysqli_close($con);
}
?>
I wouldn't normally include so much HTML but I thought maybe I messed something up in there that may be the issue, and I just don't realize it. I tried to take out most of the break and header tags to clean up the code a bit.
Thanks for any help!
Regards.
The documentation of .submit() states, that
Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures.
You have an input that has the name submit.
<input type="submit" id="submitEntry" style="font-family:Raleway;" class="inputButton" type="button" name="submit" value="Submit Entry" />
I tried it with and without that name. It works without!
I found the following to work:
<script>
function initEntrySubmission() {
var serializedProtocol = $("#protocolForm :input").serialize();
alert(serializedProtocol);
$('#serialInput').val(serializedProtocol);
return true;
}
</script>
<form id="entryForm" action="" method="post" onSubmit="return initEntrySubmission();">
...
<input type="submit" id="submitEntry" style="font-family:Raleway;" class="inputButton" value="Submit Entry"/>
</form>
The main things to do are to add an onSubmit to your form tag. The function must return either true or false. Return true will submit the form.
Also, you do need to clean up your HTML, there are select statements in there, without closing tags and your submit button
<input type="submit" id="submitEntry" style="font-family:Raleway;" class="inputButton" type="button" name="submit" value="Submit Entry" /
has no ending >, it also has 2 type attributes type="button" and type="submit"(its both a button and a submit?) and has a name=submit, which is also unnecessary .
You don't have to preventDefault(), the Code will still be run before the Form is submitted.
function initEntrySubmission() {
var serializedProtocol = $("#protocolForm :input").serialize();
console.log(serializedProtocol);
$('#serialInput').val(serializedProtocol);
}
You can try something like below
In HTML just add
<form id="entryForm" action="add_entry.php" method="post" onsubmit="return false;">
And in JS function
function initEntrySubmission(e) {
var serializedProtocol = $("#protocolForm :input").serialize();
$('#serialInput').val(serializedProtocol);
$('#entryForm').removeAttr('onsubmit');
$('#entryForm').submit();
}
Just change:
$('#entryForm').submit();
To:
$('#entryForm')[0].submit();
Also rename your submit element as #Matmarbon has so eloquently explained.
Explanation:
$('#entryForm').submit(); simply triggers the submit event and takes you back to square one.
$('#entryForm')[0].submit(); submits the form ... more like the default action, without triggering the submit event.
I have a form where a user inputs a word, when pressing the button I want it to translate the word (using the jquery script) into the same field.
Only after completed to populate the field, it should continue and submit the translated word.
everything is working except that it will submit as soon as it translating causing the original word to be submitted instead of the translated one.
the original page shows that the word had been translated.
please help on how to make it submit only after the word have been translated in the text field. ?
should I use a delay ? if so how ?
or is there an oncomplete, "onpopulate" or something like that ?
here is the script:
<script type="text/javascript">
$(function transle() {
$('#transbox').sundayMorningReset();
$('#transbox input[type=submit]').click(function(evt) {
$.sundayMorning(
$('#transbox input[type=text]').val(),
{ source:'', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},
function(response) {
$('#transbox input[type=text]').val(response.translation);
}
);
});
});
</script>
and the form:
<table id="transbox" width="30px" border="0" cellspacing="0" cellpadding="0">
<form action="custom-page" method="get" name="form1" target="_blank" id="form1" >
<tr>
<td><input id="q" name="q" type="text" class="search_input" value="Evening dress" /></td>
<td><input type="submit" /></td>
</tr>
</form>
</table>
there are another JS called for the script but I don't sure its needed for the question.
thank you.
you can use type="button" instead of type="submit" and after filling call submit event of your form
function(response) {
$('#transbox input[type=text]').val(response.translation);
document.forms.form1.submit();
}
<input type="button" />
