I have a form within a SimpleModal modal, but when I try to use serialize with jQuery, the form data is always blank. The form serialize works outside of the modal, so theres something preventing the serialize from grabbing the form data. This is the code I am using:
<div id="address_form" style="display:none">
<div id="contact-area">
<form id="address_form" action="submit" method="POST">
<label for="Street">Street:</label>
<input type="text" name="Street" id="street" />
<input type="submit" name="submit" class="submit-button" />
</form>
</div>
</div>
$("#address_form").submit(function(){
var data = $(this).serialize();
alert(data)
return false;
});
You have two elements with the id of address_form. Change the id on the DIV with that id and it will work.

I am trying to post the form from modal. To keep the current page, I target post to the iFrame.
Which trigger is triggered after posting the form? Or any other solution to close modal after post?
OnSubmit, as seen in the code, do not work.
<div class="modal-body">
<form method="post" id="modalForm" action="/Test/TestForm" target="myframe">
<input type="text" name="id" required />
<input type="text" name="name" required />
<input type="submit" value="Post" onsubmit="alert('after post - close modal!');" />
</form>
</div>
You can post form via Ajax and get the begin and end request by using the following approach:
<script>
$(document).ajaxStart(function () {
//display loading, etc.
});
$(document).ajaxComplete(function () {
//hide loading, etc.
});
</script>
I am trying to create multiple forms which have two buttons, each will submit the form to different script, one via ajax and second one will just submit the form.
<?php foreach($objects as $object) : ?>
<div class="card-body">
<form id="edit-form" action="#" method="POST">
<input name="subject" value="<?=$object['subject']?>" type="text" id="title" class="input-xxlarge">
<textarea id="content" name="content" rows="25"><?=$object['content']?></textarea>
<button type="button" id="send-button" class="btn btn-primary">Send</button>
<input type="submit" id="submit-button" value="Submit"/>
</form>
</div>
<?php endforeach; ?>
First I am trying to get the current form, but I have problem with that. console.log shows something only on the first form, if I click on the buttons from other forms then It will do nothing.
$('#send-button').on('click', function(e) {
e.defaultPrevented;
$form = $(this);
$url = $form.attr('action');
$data = $form.serialize(); console.log($form);
console.log($url);
});
Is it because my button has same ID for every form ?
You shouln't use ID's multiple times on the same page. Try to use a class for that case. Also as stated in the comments use e.preventDefault(); to stop the event.
$(this) will result in the #send-button beeing targeted. To access the form you need to find the closest form element like this:
$form = $(this).closest('form');
html:
<form method="POST" action="#">
<input type="text">
<button type="button">send</button>
<input type="submit" value="submit" />
</form>
<form method="POST" action="#">
<input type="text">
<button type="button">send</button>
<input type="submit" value="submit" />
</form>
js:
$("form").each(function() {
var form = this;
$(form).find('button').on('click', function(e) {
e.preventDefault();
console.log(form);
console.log(this);
})
});
this will add events on every form you have on your page, button will submit form via script and submit will just submit it. also here's a fiddle to play with
I have a multiple forms in a page and i would like to get the elements of a specific form. For example:
<form class="form" id="1">
<input type="text" name="message" value="message">
<button type="submit" value="submit">Submit</button>
</form>
<form class="form" id="2">
<input type="text" name="message" value="message">
<button type="submit" value="submit">Submit</button>
</form>
How to get the value of message of form id=2...... Thanks in advance
Just use attribute selectors
$('form[id=2]') // get the form with id = 2
.find('input[name=message]') // locate the input element with attribute name = message
.attr("value"); // get the attribute = value
You really shouldn't use raw numbers for ids, let's rename those to form_1 and form_2, then your jquery selector would be:
$("#form_2 [name='message']").val();
Simply query the input from the id of the form you'd like
console.log($('#2 input').val());
//more specific
console.log($('#2 input[name="message"]').val());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class="form" id="1">
<input type="text" name="message" value="message">
<button type="submit" value="submit">Submit</button>
</form>
<form class="form" id="2">
<input type="text" name="message" value="message">
<button type="submit" value="submit">Submit</button>
</form>
You can use jQuery, or you can use basic JavaScript to return the message value. With basic JS, you would have to give your form a name, but then could return the message value.
Code:
function getValue() {
var message = document.forms["form_name"]["message"].value;
}
You would then have to return the function when the form is submitted
<form class="form" name="form_name" onsubmit="return getValue()">
I am doing a web application using javascript and html that has a form containing a text field, button. When I enter a number in that text field and submit by clicking on that button, text areas are generated dynamically. Once my form is submitted some text areas are created but if I am not satisfied with existing text areas then again I enter some value with out refreshing page. But the text field value entered previously prevails showing the new text areas below the existing text areas on the page.
So, how do I clear the value with out refreshing the page.
<div>
<html>
<input type="text" name = "numquest" id ="numquest" value="" size="5" style="" disabled>
<input type="button" value="submit" onclick="getFields();">
</div>
</html>
<javascript>
var num_q=document.getElementById('numquest').value;
//code for dynamic creation
</javascript>
try this:
Using jQuery:
You can reset the entire form with:
$("#myform")[0].reset();
Or just the specific field with:
$('#form-id').children('input').val('')
Using JavaScript Without jQuery
<input type="button" value="Submit" id="btnsubmit" onclick="submitForm()">
function submitForm() {
// Get the first form with the name
// Hopefully there is only one, but there are more, select the correct index
var frm = document.getElementsByName('contact-form')[0];
frm.submit(); // Submit
frm.reset(); // Reset
return false; // Prevent page refresh
}
You can set the value of the element to blank
document.getElementById('elementId').value='';
Assign empty value:
document.getElementById('numquest').value=null;
or, if want to clear all form fields. Just call form reset method as:
document.forms['form_name'].reset()
you can just do as you get that elements value
document.getElementById('numquest').value='';
<form>
<input type="text" placeholder="user-name" /><br>
<input type=submit value="submit" id="submit" /> <br>
</form>
<script>
$(window).load(function() {
$('form').children('input:not(#submit)').val('')
}
</script>
You can use this script where every you want.
It will clear all the fields.
let inputs = document.querySelectorAll("input");
inputs.forEach((input) => (input.value = ""));
HTML
<form id="some_form">
<!-- some form elements -->
</form>
and jquery
$("#some_form").reset();
I believe it's better to use
$('#form-id').find('input').val('');
instead of
$('#form-id').children('input').val('');
incase you have checkboxes in your form use this to rest it:
$('#form-id').find('input:checkbox').removeAttr('checked');
.val() or .value is IMHO the best solution because it's useful with Ajax. And .reset() only works after page reload and APIs using Ajax never refresh pages unless it's triggered by a different script.
I had that issue and I solved by doing this:
.done(function() {
$(this).find("input").val("");
$("#feedback").trigger("reset");
});
I added this code after my script as I used jQuery. Try same)
<script type="text/JavaScript">
$(document).ready(function() {
$("#feedback").submit(function(event) {
event.preventDefault();
$.ajax({
url: "feedback_lib.php",
type: "post",
data: $("#feedback").serialize()
}).done(function() {
$(this).find("input").val("");
$("#feedback").trigger("reset");
});
});
});
</script>
<form id="feedback" action="" name="feedback" method="post">
<input id="name" name="name" placeholder="name" />
<br />
<input id="surname" name="surname" placeholder="surname" />
<br />
<input id="enquiry" name="enquiry" placeholder="enquiry" />
<br />
<input id="organisation" name="organisation" placeholder="organisation" />
<br />
<input id="email" name="email" placeholder="email" />
<br />
<textarea id="message" name="message" rows="7" cols="40" placeholder="сообщение"></textarea>
<br />
<button id="send" name="send">send</button>
</form>
You can assign to the onsubmit property:
document.querySelector('form').onsubmit = e => {
e.target.submit();
e.target.reset();
return false;
};

I have the following dynamically generated HTML
<div id="1">
<form name = "inpForm">
<input name="FirstName" type="text"/>
<input type="submit" value="Submit"/>
</form>
</div>
<div id="2">
<form name = "inpForm">
<input name="FirstName" type="text"/>
<input type="submit" value="Submit"/>
</form>
</div>
The outer divs have different IDs but the form names are the same. I am using Jquery to perform some validation when the form is submitted. However, when the second form is submitted, I always get the values of the first form.
$(document).ready(function () {
$('form[name="inpForm"]').live('submit', function () {
alert($('input[name="FirstName"]').val());
return false;
});
});
How can I modify myJquery to find the "FirstName" element that matches the current form where the submit was triggered?
Thanks
Add some context:
alert($(this).find('input[name="FirstName"]').val());
Use this (the form-element) as context-argument:
alert($('input[name="FirstName"]',this).val());
