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 an input like the one below:
<input class="submit" type="submit" name="submit" value="Blah">
I want to change the value to 'Other Text'.
When I use the .val(),attr() or .prop() jQuery method the value changes fine but when I submit, the input doesn't work any more.Just refreshes the page without doing what its supposed to.
Same result with .setAttribute method.
How do I get the input to work correctly now the value has been changed?
Try this
<input type=button name="b1" value="Submit" onclick="javascript:document.MyForm.b1.value='Done'">
Source : Change text on submit button after submission
Check this
$(document).ready(function(){
$(".submit").click(function(){
$(this).val("OtherText");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="submit" type="submit" name="submit" value="Blah">
I believe it was server side script was checking the value, so had to change the value back when clicked.
if ($('.submit').length > 0) {
$('.submit').prop('value', 'Other Text');
$('.submit').click(function(){
$('.submit').prop('value', 'blah');
});}
This seems to be working 'ok' now. Not ideal but works
You can prevent submitting form or in click event of button:
$(".submit").click(function(e){
e.preventDefault();
$("#inputbox").val("OtherText");
//Now you can submit form manually here
$("#form").submit();
});
I have a problem on html button tag
This my html code
<form name="data_kirim" action="confirm_order.php" method="POST">
..... order input field ....
<button class="back_button" onclick="window.location.href='keranjang.php'">Back</button>
<input class="next_button" type="submit" name="submit_data_kirim" value="Next"/>
</form>
How to prevent button to submit this form, because button is using the href to back page,
Can someone help me?
change
type='submit'
to
type='button'
<button class="back_button" onclick="window.location.href='keranjang.php'">Back</button>
<form name="data_kirim" action="confirm_order.php" method="POST">
<input class="next_button" type="submit" name="submit_data_kirim" value="Next"/>
</form>
A quick solution would be to move the back button outside the form since It's not using the form inputs anyway.
you can call a function in javascript when click your button, redirect to your link and return false or use preventDefault() function with jquery
<form onsubmit="return false;">
If you want to just make it link to another page and not submit the form then simply make it a normal button like so :
Next
This will not submit the form though.
Can anybody tell me Why I click on button to submit form -> it works, but when I use javascript to auto submit -> it failed ?
I have this form on aaa.com, it submit to bbb.com/result.jsp (another domain)
<form id="myForm" name="myForm " method="post" action="www.bbb.com/result.jsp">
<input name="var01" value="var01 ">
<input name="var02" value="var02 ">
<input type="submit" name="searchButton" value="Search">
</form>
Manually click on Search button, result.jsp works fine.
When I added following script, result.jsp page doesn’t work
<script>
document.getElementById("myForm").submit();
</script>
Your form has id="myForm" but your JavaScript is looking for myform. IDs are case-sensitive.
Changing that makes it work.
As I remember, the HTML id attribute is case-sensitive. You are calling the .submit() method on myform while your form id is myForm.
I am building a PhoneGap application using JavaScript, HTML and jQuery Mobile.
All the HTML is in the same file, separated into <div data-role="page"> as pages.
Several pages have a form including one or more text/selection input and a submit button.
The submit is not a traditional form submit button but a button which using onClick runs a JavaScript function which can do many things.
I want the form to have this features:
When pressing the button and after running the function, clear the form.
In some cases the function should change the page.
The enter button on one of the inputs should submit the form (Activate the function).
Should I use the form HTML tag? If so what should I use for action? How to clear the form?
etc.
If you are trying to bind onClick to an input type="submit" then you're gonna have a bad time.
Unfortunately even if you return false or e.preventDefault when clicking that button, the form still sends the submit trigger so once your onClick code is finished then it will submit.
Example:
<form action="woot.php" method="POST">
<input type="submit" value="submit" onClick="alert('You clicked me! How could you?! It's cool the form will still go to woot.php. return FALSE wont help you either.'); return FALSE;">
</form>
What you probably want to do:
<form action="woot.php" method="POST">
<input type="submit" value="Submit" onSubmit="alert('You aint goin nowhere!'); return FALSE;">
</form>
What you should do:
<form action="woot.php" method="POST">
<input type="button" value="Button" onClick="alert('Away with you!'); window.location = 'http://www.google.com/';">
<input type="button" value="Button" onClick="someCoolFunction();">
</form>
I wouldn't use type="button", especially if you want to have the best chance of the form submitting when the user presses enter.
Use your regular form <input type="submit"> and then your JavaScript:
$('form').submit(function(e) {
// all your form handling here;
if (your_form_was_validated_and_handled) {
$('input[type!="submit"]').val('');
}
e.preventDefault();
});
Generic fiddle: http://jsfiddle.net/
You can still use the form tag, as it's useful for markup.
Just make sure that your buttons have attribute
type="button"
otherwise the button will submit the form by default.
To reset the form:
function resetForm() {
$('#form').each(function(){
this.reset();
});
}
