Why won't my js form submit work? [duplicate] - javascript

This question already has answers here:
Property 'submit' of object #<HTMLFormElement> is not a function
(3 answers)
Closed 9 years ago.
I have an iframe and a form. I want to submit the form into the iframe. This works, but the JS won't submit the form. I want the form to submit on page load or just when the script is rendered by the browser. I have already tried about 10 different JavaScript variants and successfully submitted the form with a button. Any thoughts?
<iframe src="http://domain.com" name="i0"></iframe>
<form action="http://domain.com/" target="i0" id="f0" method="POST">
<input type="hidden" name="secret" value="4cda562cd5dafa1882c9f18dc0dc5dba">
<input type="hidden" name="id" value="39">
</form>
<script type='text/javascript'>
document.getElementById('f0').submit();
</script>

<input type="submit" name="submit">
this is what's causing your issue, change its name to something else. because now this
document.getElementById('f0').submit();
is trying to access that input, and giving the error:
TypeError: document.getElementById(...).submit is not a function
You should have posted all your form code here, we could have found it faster :)

Maybe it is because your iframe hasn't fully loaded yet, so you need to wait for it:
<script type='text/javascript'>
document.getElementsByName('iframe')[0].onload = function(){
document.getElementById('f0').submit();
}
</script>

I see, you cant' use name="submit" here because you are overwritting FORM submit method, change it, e.g:
<input type="submit" name="bsubmit">

Make hyperlink a form submit button

I am trying to get a hyperlink element to act as a form submit button. This sort of question has been answered multiple times over the years but, for some reason, I am not able to get it to work even with cut-n-pasted code and I'm wondering if I'm missing something trivially simple that my eyes are too bugged out to see. The full code is here:
<html>
<head>
<script language="JavaScript" type="text/javascript">
<!--
function signup() {
alert("Form is " + document.signup_form);
document.signup_form.submit() ;
}
-->
</script>
</head>
<body>
<?php
echo("Submit is [" . $_POST['submit'] . "]");
?>
<form method="post" name="signup_form" id="signup_form" action="" >
<input type="text" name="from_email" placeholder="e-mail address"><br>
<input type="submit" name="submit" value="Send Email">
Sign Up!<br>
</form>
</body>
</html>
The input submit element ("Send Email") works fine. The hyperlink ("Sign Up!") also works fine and calls the javascript function so that the alert() box in the function shows up.
So, it's just the submit() call that's not doing anything--I even printed out document.signup_form in an alert() box to confirm that it's defined (it is). So what am I missing here?
Thanks for any help!
There is a weird thing with how forms work with Javascript - each field is accessible by using formElement.fieldName. Unfortunately, that means that if you name a field input submit, all of a sudden the built-in formElement.submit() function is replaced by your input element. So in your code, document.signup_form.submit() is failing because it is calling the element, not the method, and you can't call an element as a function. See this SO QA for details.
The fix is easy - change:
<input type="submit" name="submit" value="Send Email">
to:
<input type="submit" name="submitBtn" value="Send Email">
Also, as others have noted, you will want to give your form a valid action. Also, in general it might be preferred to access things by id (document.getElementById()) instead of by things like document.signup_form.
Your <form> element is missing a value in it's action attribute. Quoting the specs:
You also have to specify the URL of the service that will handle the
submitted data, using the action attribute

Javascript Auto Form submission not working

I have following simple HTML Form & i tried to submit the form automatically during page load.
Below Javascript code is not automatically submitting the form.
HTML :
<form action="SSL.php" method="POST" name="TForm" id="transactionForm">
<input type="hidden" name="merchantTxnId" id="merchantTxnId" value="test">
<input type="submit" name="submit" id="submit" value="submit" style="visibility:hidden">
</form>
Redirecting ... Please wait...
Java script:
<script>
window.onload = function(){
alert(1); // this is working..
document.getElementById("transactionForm").submit(); //nothing is happening with this line . form is not getting submitted
}
</script>
I found following error in Chrome console mode says:
Kindly suggest me where the problem is...
You may not use submit as the name or id of any of your form elements.
The reason is, that you can reach each child of your form via document.getElementById('form').nameOfTheChild where nameOfTheChild is the name of the child. If you have a child with the name submit, document.getElementById('form').submit is a shortcut to address that child.
The documentation of .submit() says 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.

Cannot programmatically submit form [duplicate]

"Submit is not a function" error in JavaScript
(19 answers)
Closed 8 years ago.
Cannot get my form to submit programmatically, despite trying several ways. Tried pure JS, also tried jQuery. No success.
I have this form tag :
<form action="https://docs.google.com/forms/d/13zex8ZsEsnZz3A8uB4jU4oDb5wZfaqqq2Pq2CGlIe6M/formResponse" method="POST" id="ss-form" target="_self" onsubmit="" name="eForm">
<!--My Form Stuff-->
<input type="submit" name="submit" value="Submit" id="ss-submit">
</form>
Here is what i've tried :
/*jQuery*/
$('#ss-form').submit();
/*Javascript*/
document.getElementById('ss-form').submit();
document.eForm.submit();
None of them work. Not sure why, but I am assuming it has something to do with me trying to submit a google form. If I physically click the submit everything works fine.
Any and all help is greatly apprecaiated.
The problem is that you have a field (HTMLInputElement) with name submit in the form. That's why document.getElementById('ss-form').submit is not a function but an object.
So, you get the following error:
TypeError: object is not a function
The solution is to remove that element. We should be careful to verify if browser thinks it's an element and not a function:
if (typeof document.getElementById('ss-form').submit === "object") {
document.getElementById('ss-form').submit.remove();
}
document.getElementById('ss-form').submit();

Not able to submit form in chrome through javascript

Form submission is working good on both IE and Firefox, but recently i tested my application on chrome. In that i found chrome is not submitting form, there are no error messages in chrome console, can u help me. i had gone through server answers , still i didn't get proper solution. here is my js code
<script type="text/javascript">
function callModule(){
document.frmcheckUserDomain.submit();
}
</script>
<form name="frmcheckUserDomain" action="checkUserDomain.do" method="post">
// here is my form fields
<input type="button" name="subBtn" value="Submit" onClick="callModule();" />
</form>
Try changing your callModule method to this...
function callModule(){
document.getElementById("frmcheckUserDomain").submit();
}
Also, you will want to give your form tag an id attribute...
You could also access the form via index as well...
function callModule() {
document.forms[0].submit();
}
first of all why don't you use input submit button instead, like:
<input type="submit" name="subBtn" value="Submit" />
and if you have some stuff to do when the form gets submitted, you can use onsubmit event in your form.
And for your solution, you can pass it as an argument and then submit it:
<input type="button" name="subBtn" value="Submit" onClick="callModule(this);" />
your function:
function callModule(elm){
elm.parentNode.submit();
}
see, your code is working fine in my Google chrome. i think u have some issues with your browser or better u check the java Servlet configuration.

Help me fix my JavaScript Quiz
Hi, this javascript form isn't working as there is some kind of bug/error in the code which I can't find! It should activate a pop-up after answering the 4 questions and clicking the 'submit' button - letting the user know if they have passed or failed the little test.
Instead of posting all the code it is here in the doc. head here: http://bit.ly/g4jO3J
Any help would be appreciated for this project.
You have a redundant onclick= in your submit button. Instead of:
<input name="button" type="Submit" onClick="onclick=return checkAnswers()" />
Use:
<input name="button" type="Submit" onClick="return checkAnswers()" />
Your script contains HTML:
<script>
// your code
<form name="Quiz" onsubmit="return validate(this)">
<input type="submit" />
</form>
</script>
That causes a syntax error. But that's probably not the problem.
function validate(myForm) { => function validate() {
var allQuestions = new Array(Quiz.q1,Quiz.q2,Quiz.q3,Quiz.q4); => var allQuestions = new Array(document.Quiz.q1,document.Quiz.q2,document.Quiz.q3,document.Quiz.q4);
onClick="return checkAnswers()" => onClick="return validate()"
Thanks for your help - I got it working eventually!!
