Understanding Javascript loading in Zombie

[Jagdeep Rao]

Hi,

 I have a page that makes liberal use of javascript for various validations and other tasks. One of these is that the submit click leads to some computations and setting of some values in cookies and hidden fields followed by the script invoking the submit method on the form. Problem is the script references for example the submit for form -

<form action="/logon" method="POST" name="logonForm" enctype="application/x-www-form-urlencoded" autocomplete="off">

.

.

</form>

with Javascript - 

document.logonForm.submit();

This does not work in zombie - I get an error message that states - "TypeError: Cannot read property 'submit' of undefined". 

Any idea how this can be resolved?

Try document.getElementById(id)

Can't. The javascript is not in my control. <form name=xyz.../> being accessed as document.formXyz is this enabled by JSDOM? Can I manipulate the dom and thereby be able to submit the form from the javascript as is?

Also another point to note is that the HTML shows the form (i.e. form is not being added dynamically), but browser.document.getElementsByClassName('logonForm')[0] is undefined, I am accessing other elements with getElementsByClassName(). The only issue seems to be <form> with a class name. Is this a known bug?

[Assaf Arkin]

FYI your example from before, the form element doesn’t have a class name.

My apologies, getElementsByName() is working fine, as is getElementsByClassName(). Typo led to the undefined. The issue is the DOM tree being referred to by the javascript does not see the form element. So I am wondering if the source of the problem is related to one of the dependencies of zombie...

[Assaf Arkin]

Yeah, it’s part of the DOM so first place to look for this would be JSDOM.

Confirmed JSDOM issue. It is there in the latest version of JSDOM too. Ofcourse cannot post using JSDOM alone but the element document.logonForm is undefined there as well.
