How can I add JavaScript code to the source code?

I would like to add a generated JavaScript code before the tag into the source code of my form.  Is there a way for me to do this?

The only way to add custom Javascript to the form is to use your form source code: How-to-Download-a-Source-Code-of-your-Form. There's no other way to do it other than this. The downside with using source code is to update them whenever you made changes to your form in the form builder.

We will be able to provide you with the appropriate suggestion if you can share to us the URL of your website where you used the source code embed of the form.

Usually, the javascript code can be added on the website page where the form was embedded, within the Head tag of the page.
