Question

So I have a form and I would like to disable the submit ‘button’ on the form after the user has clicked on it once to prevent multiple submits, and I was wondering how I will be able to achieve this result. So the code goes something like this:

<form id = "id" name= "blah" method = "post" onsubmit="$('input[type=submit]').attr('disabled', 'disabled');" ...>
items for the form goes here
<input title="Save" type="submit" value="Save" tabindex="20"/>

But I’m getting an error in the console:
“Error: The value of the property ‘$’ is null or undefined, not a Function object”

Answer 1

use the following code

onsubmit=”document.getElementById(‘submit’).disabled = 1;”

let me know if it is not works.
