Set the name attribute of your form to "theForm" and your code will work., 16 This may seem super-obvious to some, but i had a button with the name and id "submit", and document.theForm.submit() reported an error. Once I renamed my button, the code worked perfectly. – Jonathan Oct 9 '17 at 4:20 ,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:,I will leave the way I do to submit the form without using the name tag inside the form:

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);

Standard HTML form submission, as described in the previous article, loads the URL where the data was sent, which means the browser window navigates with a full page load. Avoiding a full page load can provide a smoother experience by avoiding network lag, and possible visual issues like flickering.,Many modern UIs only use HTML forms to collect input from the user, and not for data submission. When the user tries to send the data, the application takes control and transmits the data asynchronously in the background, updating only the parts of the UI that require changes.,With progressive web apps, single page apps, and framework based apps, it's common to use HTML forms to send data without loading a new document when response data is received. Let's first talk about why this requires a different approach.,In the following example, we use the FileReader API to access binary data and then build the multi-part form data request by hand:

<button>Click Me!</button>
