Ok, this is less of a question than it is just for my information (because I can think of about 4 different work arounds that will make it work. But I have a form (nothing too special) but the submit button has a specific value associated with it.

<input type='submit' name='submitDocUpdate' value='Save'/>

And when the form gets submitted I check for that name.

if(isset($_POST['submitDocUpdate'])){ //do stuff

However, there is one time when I'm trying to submit the form via Javascript, rather than the submit button.

document.getElementById(myForm).submit();

Which is working fine, except 1 problem. When I look at the $_POST values that are submitted via the javascript method, it is not including the submitDocUpdate. I get all the other values of the form, but not the submit button value.

Like I said, I can think of a few ways to work around it (using a hidden variable, check isset on another form variable, etc) but I'm just wondering if this is the correct behavior of submit() because it seems less-intuitive to me. Thanks in advance.
