I have an old website with JQuery 1.7 which works correctly till two days ago. Suddenly some of my buttons do not work anymore and, after clicking on them, I get this warning in the console:
Form submission canceled because the form is not connected
The code behind the click is something like this:
this.handleExcelExporter = function(href, cols) {
var form = $('<form method="post"><input type="submit" /><input type="hidden" name="layout" /></form>').attr('action', href);
$('input[name="layout"]', form).val(JSON.stringify(cols));
$('input[type="submit"]', form).click();
}
It seems that Chrome 56 doesn't support this kind of code anymore. Isn't it? If yes my question is:
P.S. It doesn't work in the latest firefox version either (without any message). Also it does not work in IE 11.0 & Edge! (both without any message)
This question is related to
javascript
jquery
google-chrome
jquery-1.7
alternatively include event.preventDefault(); in your handleSubmit(event) {
A thing to look out for if you see this in React, is that the <form>
still has to render in the DOM while it's submitting. i.e, this will fail
{ this.state.submitting ?
<div>Form is being submitted</div> :
<form onSubmit={()=>this.setState({submitting: true}) ...>
<button ...>
</form>
}
So when the form is submitted, state.submitting
gets set and the "submitting..." message renders instead of the form, then this error happens.
Moving the form tag outside the conditional ensured that it was always there when needed, i.e.
<form onSubmit={...} ...>
{ this.state.submitting ?
<div>Form is being submitted</div> :
<button ...>
}
</form>
I see you are using jQuery for the form initialization.
When I try @KyungHun Jeon's answer, it doesn't work for me that use jQuery too.
So, I tried appending the form to the body by using the jQuery way:
$(document.body).append(form);
And it worked!
Adding for posterity since this isn't chrome related but this was the first thread that showed up on google when searching for this form submission error.
In our case we attached a function to replace the current div html with a "loading" animation on submission - since it occurred before the form was submitted there was no longer any form or data to submit.
Very obvious error in retrospect but in case anyone ends up here it might save them some time in the future.
You must ensure that the form is in the document. You can append the form to the body.
I have received this error in react.js. If you have a button in the form that you want to act like a button and not submit the form, you must give it type="button". Otherwise it tries to submit the form. I believe vaskort answered this with some documentation you can check out.
Depending on the answer from KyungHun Jeon, but the appendChild expect a dom node, so add a index to jquery object to return the node:
document.body.appendChild(form[0])
I was able to get rid of the message by using adding the attribute type="button" to the button element in vue.
I saw this message using angular, so i just took method="post" and action="" out, and the warning was gone.
if you are seeing this error in React JS when you try to submit the form by pressing enter, make sure all your buttons in the form that do not submit the form have a type="button"
.
If you have only one button
with type="submit"
pressing Enter will submit the form as expected.

I have found this problem in my React project.
The problem was,
So, while clicking on the button, the onclick function is firing and the form is NOT submitting, and the console is printing -
Form submission canceled because the form is not connected
The simple fix is:
add attribute type="button" to the button on who's click you see the error, it worked for me.
<button type="button">my button</button>
we have to add attribute above in our button element
I faced the same issue in one of our implementation.
we were using jquery.forms.js. which is a forms plugin and available here. http://malsup.com/jquery/form/
we used the same answer provided above and pasted
$(document.body).append(form);
and it worked.Thanks.
I noticed that I was getting this error, because my HTML code did not have <body>
tag.
Without a <body>
, when document.body.appendChild(form);
statement did not have a body object to append.
You can also solve it, by applying a single patch in the jquery-x.x.x.js just add after " try { rp; } catch (m) {}" line 1833 this code:
if (r instanceof HTMLFormElement &&! r.parentNode) {
r.style.display = "none"; document.body.append (r);
r [p] ();
}
This validates when a form is not part of the body and adds it.
