Can anyone tell me what is going wrong with this code? I tried to submit a form with JavaScript, but an error ".submit is not a function" shown. See below for more details of the code:
<form action="product.php" method="get" name="frmProduct" id="frmProduct" enctype="multipart/form-data">
<input onclick="submitAction()" id="submit_value" type="button" name="submit_value" value="">
</form>
<script type="text/javascript">
function submitAction()
{
document.frmProduct.submit();
}
</script>
I also tried this:
<script type="text/javascript">
function submitAction()
{
document.forms["frmProduct"].submit();
}
</script>
Both show me the same error :(
submit is not a function
means that you named your submit button or some other element submit. Rename the button to btnSubmit and your call will magically work.
When you name the button submit, you override the submit() function on the form.
Make sure that there is no another form with the same name and make sure that there is no name="submit" or id="submit" in the form.
If you have no opportunity to change name="submit" you can also submit form this way:
function submitForm(form) {
const submitFormFunction = Object.getPrototypeOf(form).submit;
submitFormFunction.call(form);
}
<form action="product.php" method="post" name="frmProduct" id="frmProduct" enctype="multipart/form-data">
<input id="submit_value" type="button" name="submit_value" value="">
</form>
<script type="text/javascript">
document.getElementById("submit_value").onclick = submitAction;
function submitAction()
{
document.getElementById("frmProduct").submit();
return false;
}
</script>
EDIT: I accidentally swapped the id's around
I had the same issue when i was creating a MVC application using with master pages.
Tried looking for element with 'submit' as names as mentioned above but it wasn't the case.
For my case it created multiple tags on my page so there were some issues referencing the correct form.
To work around this i'll let the button handle which form object to use:
onclick="return SubmitForm(this.form)"
and with the js:
function SubmitForm(frm) {
frm.submit();
}
form.submit() will not work if the form does not have a <button type="submit">submit</button>. form element belongs to HTMLFormElement interface, therefore, we can call from prototype directly, this method will always work for any form element.
HTMLFormElement.prototype.submit.call(form)
This topic has a lot of answers already, but the one that worked best (and simplest - one line!) for me was a modification of the comment made by Neil E. Pearson from Apr 21 2013:
If you're stuck with your submit button being #submit, you can get around it by stealing another form instance's submit() method.
My modification to his method, and what worked for me:
document.createElement('form').submit.call(document.getElementById(frmProduct));
I had same issue and resolved my issue just remove name="submit" from submit button.
<button name='submit' value='Submit Payment' ></button>
Change To
<button value='Submit Payment' ></button>
remove name attribute hope it will work
Sorry to answer late but for those who are still facing the same error. To get rid of this error:
<form method="POST">
<input type="text"/>
<input type="submit" id="submit-form" value="Submit Form" style="display: none;"/>
</form>
<!-- Other element that will submit the form -->
<button onclick="submitTheForm()">Submit the form</button>
<script>
function submitTheForm(){
document.getElementById("submit-form").click();
}
</script>
Explanation:
The javascript function submitTheForm() is accessing the submit input element and calling the click event on it which results in the form submission.
This solution is lifetime and almost 100% compatible in all browsers.
giving a form element a name of submit will simple shadow the submit property .
make sure you don't have a form element with the name submit and you should be able to access the submit function just fine .
In fact, the solution is very easy...
Original:
<form action="product.php" method="get" name="frmProduct" id="frmProduct"
enctype="multipart/form-data">
<input onclick="submitAction()" id="submit_value" type="button"
name="submit_value" value="">
</form>
<script type="text/javascript">
function submitAction()
{
document.frmProduct.submit();
}
</script>
Solution:
<form action="product.php" method="get" name="frmProduct" id="frmProduct"
enctype="multipart/form-data">
</form>
<!-- Place the button here -->
<input onclick="submitAction()" id="submit_value" type="button"
name="submit_value" value="">
<script type="text/javascript">
function submitAction()
{
document.frmProduct.submit();
}
</script>
Possible solutions -
1.Make sure that you don't have any other element with name/id as submit.
2.Try to call the function as onClick = "return submitAction();"
3.document.getElementById("form-name").submit();
You should use this code :
$(document).on("ready", function () {
document.frmProduct.submit();
});
What I used is
var enviar = document.getElementById("enviar");
enviar.type = "submit";
Just because everything else didn´t work.
Solution for me was to set the "form" attribute of button
<form id="form_id_name"><button name="btnSubmit" form="form_id_name" /></form>
or is js:
YOURFORMOBJ.getElementsByTagName("button")[0].setAttribute("form", "form_id_name");
YOURFORMOBJ.submit();
I faced this issues also but i made a quick fix using
const form = document.getElementById('create_user_form');
function onSubmit(event) {
console.log(event.target[0].value);
console.log(form.submit); // 👉️ input#submit
// ✅ Works
HTMLFormElement.prototype.submit.call(form);
}
form.addEventListener('submit', onSubmit);
Even though accessing the submit property on the form element points to the submit input element and not the method, we can still submit the form by accessing the submit property on the HTMLFormElement interface.
I was facing the same problem that my submit() wasn't working. In my case, I'd an id="submit" on the input tag having type="submit", I removed the id, and it started working.
You can try
<form action="product.php" method="get" name="frmProduct" id="frmProduct" enctype="multipart/form-data">
<input onclick="submitAction(this)" id="submit_value" type="button" name="submit_value" value="">
</form>
<script type="text/javascript">
function submitAction(element)
{
element.form.submit();
}
</script>
Don't you have more than one form with the same name ?
Use getElementById:
document.getElementById ('frmProduct').submit ()

I have a form with id theForm which has the following div with a submit button inside:
<div id="placeOrder"
style="text-align: right; width: 100%; background-color: white;">
<button type="submit"
class='input_submit'
style="margin-right: 15px;"
onClick="placeOrder()">Place Order
</button>
</div>
When clicked, the function placeOrder() is called. The function changes the innerHTML of the above div to be "processing ..." (so the submit button is now gone).
The above code works, but now the problem is that I can't get the form to submit! I've tried putting this in the placeOrder() function:
document.theForm.submit();
But that doesn't work.
How can I get the form to submit?
Set the name attribute of your form to "theForm" and your code will work.
You can use...
document.getElementById('theForm').submit();
...but don't replace the innerHTML. You could hide the form and then insert a processing... span which will appear in its place.
var form = document.getElementById('theForm');
form.style.display = 'none';
var processing = document.createElement('span');
processing.appendChild(document.createTextNode('processing ...'));
form.parentNode.insertBefore(processing, form);
It works perfectly in my case.
document.getElementById("form1").submit();
Also, you can use it in a function as below:
function formSubmit()
{
document.getElementById("form1").submit();
}
document.forms["name of your form"].submit();
or
document.getElementById("form id").submit();
You can try any of this...this will definitely work...
I will leave the way I do to submit the form without using the name tag inside the form:
HTML
<button type="submit" onClick="placeOrder(this.form)">Place Order</button>
JavaScript
function placeOrder(form){
form.submit();
}
You can use the below code to submit the form using JavaScript:
document.getElementById('FormID').submit();
<html>
<body>
<p>Enter some text in the fields below, and then press the "Submit form" button to submit the form.</p>
<form id="myForm" action="/action_page.php">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br><br>
<input type="button" onclick="myFunction()" value="Submit form">
</form>
<script>
function myFunction() {
document.getElementById("myForm").submit();
}
</script>
</body>
</html>
HTML
<!-- change id attribute to name -->
<form method="post" action="yourUrl" name="theForm">
<button onclick="placeOrder()">Place Order</button>
</form>
JavaScript
function placeOrder () {
document.theForm.submit()
}
If your form does not have any id, but it has a class name like theForm, you can use the below statement to submit it:
document.getElementsByClassName("theForm")[0].submit();
I have came up with an easy resolve using a simple form hidden on my website with the same information the users logged in with. Example: If you want a user to be logged in on this form, you can add something like this to the follow form below.
<input type="checkbox" name="autologin" id="autologin" />
As far I know I am the first to hide a form and submit it via clicking a link. There is the link submitting a hidden form with the information. It is not 100% safe if you don't like auto login methods on your website with passwords sitting on a hidden form password text area...
Okay, so here is the work. Let’s say $siteid is the account and $sitepw is password.
First make the form in your PHP script. If you don’t like HTML in it, use minimal data and then echo in the value in a hidden form. I just use a PHP value and echo in anywhere I want pref next to the form button as you can't see it.
PHP form to print
$hidden_forum = '
<form id="alt_forum_login" action="./forum/ucp.php?mode=login" method="post" style="display:none;">
<input type="text" name="username" id="username" value="'.strtolower($siteid).'" title="Username" />
<input type="password" name="password" id="password" value="'.$sitepw.'" title="Password" />
</form>';
PHP and link to submit form
<?php print $hidden_forum; ?>
<pre>Forum</pre>
I have an issue while using buttons inside form. I want that button to call function. It does, but with unwanted result that it refresh the page.
My simple code goes like this
<form method="POST">
<button name="data" onclick="getData()">Click</button>
</form>
On clicking the button, the function gets called with page refreshed, which resets all my previous request which affects the current page which was result of the previous request.
What should I do to prevent the page refresh?
Add type="button" to the button.
<button name="data" type="button" onclick="getData()">Click</button>
The default value of type for a button is submit, which self posts the form in your case and makes it look like a refresh.
Let getData() return false. This will fix it.
<form method="POST">
<button name="data" onclick="return getData()">Click</button>
</form>
All you need to do is put a type tag and make the type button.
<button id="btnId" type="button">Hide/Show</button>
That solves the issue
The problem is that it triggers the form submission. If you make the getData function return false then it should stop the form from submitting.
Alternatively, you could also use the preventDefault method of the event object:
function getData(e) {
e.preventDefault();
}
HTML
<form onsubmit="return false;" id="myForm">
</form>
jQuery
$('#myForm').submit(function() {
doSomething();
});
<form method="POST">
<button name="data" onclick="getData()">Click</button>
</form>
instead of using button tag, use input tag. Like this,
<form method="POST">
<input type = "button" name="data" onclick="getData()" value="Click">
</form>
If your button is default "button" make sure you explicity set the type attribute, otherwise the WebForm will treat it as submit by default.
if you use js do like this
<form method="POST">
<button name="data" type="button" id="btnData" onclick="getData()">Click</button>
</form>
**If you use jquery use like this**
<form method="POST">
<button name="data" type="button" id="btnData">Click</button>
</form>
$('#btnData').click(function(e){
e.preventDefault();
// Code goes here
getData(); // your onclick function call here
});
A javascript method to disable the button itself
document.getElementById("ID NAME").disabled = true;
Once all form fields have satisfied your criteria, you can re-enable the button
Using a Jquery will be something like this
$( "#ID NAME" ).prop( "disabled", true);
This one is the best solution:
<form method="post">
<button type="button" name="data" onclick="getData()">Click Me</button>
</form>
Note: My code is very simple.
For any reason in Firefox even though I have return false; and myform.preventDefault(); in the function, it refreshes the page after function runs. And I don't know if this is a good practice, but it works for me, I insert javascript:this.preventDefault(); in the action attribute .
As I said, I tried all the other suggestions and they work fine in all browsers but Firefox, if you have the same issue, try adding the prevent event in the action attribute either javascript:return false; or javascript:this.preventDefault();. Do not try with javascript:void(0); which will break your code. Don't ask me why :-).
I don't think this is an elegant way to do it, but in my case I had no other choice.
Update:
If you received an error... after ajax is processed, then remove the attribute action and in the onsubmit attribute, execute your function followed by the false return:
onsubmit="functionToRun(); return false;"
I don't know why all this trouble with Firefox, but hope this works.
Return function is not working in all the cases.
I tried this:
<button id="Reset" class="Button-class" onclick="return Reset()">Show result</button>
It didnt work for me.
I tried to return false inside the function and it worked for me.
function Reset()
{
.
.
.
return false;
}
I was facing the same problem. The problem is with the onclick function. There should not be any problem with the function getData. It worked by making the onclick function return false.
<form method="POST">
<button name="data" onclick="getData(); return false">Click</button>
</form>
I updated on #JNDPNT answer, this way the function (getData()) doesn't have to return false;
<form method="POST">
<button name="data" onclick="getData(); return false;">Click</button>
</form>
A simple issue I found is that if the function that you're trying to call is called submit, the form will be submitted either way.
You will need to rename the function for the page to not be reloaded
Add e.preventDefault(); in the starting of the function to be called when the button is clicked
Example:
const signUp = (e) => {
e.preventDefault()
try {
} catch (error) {
console.log(error.message)
}
}
The button code:
<input
type='submit'
name='submit-btn'
id='submit-btn'
value='Sign Up'
onClick={signUp}
/>
You can use ajax and jquery to solve this problem:
<script>
function getData() {
$.ajax({
url : "/urlpattern",
type : "post",
success : function(data) {
alert("success");
}
});
}
</script>
<form method="POST">
<button name="data" type="button" onclick="getData()">Click</button>
</form>

Hi I have the following script in my form
function pdf() {
var frm = document.getElementById("form1");
frm.action = "http://www.abbysoft.co.uk/index.php";
frm.target="_blank"
frm.submit()
}
this is called from the following in my form
<input class="buttn" type="button" value="Test" onclick="pdf()"
The code work up to the frm.submit() but it will not submit
Can anyone offer any advice please ?
You should end your statements with ;. The following should work
function pdf()
{
var frm = document.getElementById('form1');
frm.action = 'http://www.abbysoft.co.uk/index.php';
frm.target = '_blank';
frm.submit();
}
assuming you have a form like this:
<form id="form1" action="#">
<input class="buttn" type="button" value="Test" onclick="pdf()" value="Test" />
</form>
Also make sure that by any chance you don't have an input with name submit inside your form as this would override the submit function:
<input type="text" name="submit" />
Make a form like this:
<form id="form1" action="" onsubmit="pdf();return false;">
<input class="buttn" type="submit" value="Test" value="Test" />
</form>
You haven't given us the code you are using to create the form, nor have you told us what (if any) errors are reported by the browser, however, the usual cause for this issue is having a submit button named or ided submit.
Any form control is accessible from the form object with a property that matches its name (and another one that matches its id if that is different). This clobbers any existing properties of the form (other than other controls) including the submit and reset methods.
The simplest solution is to rename the control so it doesn't conflict with an existing property.
