Error submitting a form with Greasemonkey

Question

I'm using Greasemonkey to submit a form on an external site. However, I'm running into an issue since the form's submit button is named submit .

In firebug, document.filingform.submit(); is returning the error:

document.filingform.submit is not a function

Is there a way I can use Greasemonkey to either change the name of the submit button to something other than submit, or to call the submit() function of the form successfully?

Thanks!

Answer 1

It would be something like document.forms.filingform.submit(); , but don't do it that way!

This approach is liable to be blocked by sandboxing. Also, some pages require javascript functions to run on a legitimate submit. The most robust way to submit a page, and keep it and its server happy, is to "click" the submit button.

Code like:

var submitBtn   = document.querySelector ("form[name='filingform'] input[name='submit']");
var clickEvent  = document.createEvent ('MouseEvents');

clickEvent.initEvent ('click', true, true);
submitBtn.dispatchEvent (clickEvent);
