$(form).serialize() fails when the form has an element with ID/name equals "elements"

[[email protected]…]

$(form).serialize() fails if the HTML form has an input or select control with ID (or possibly with the name attribute) set to "elements". This seems to be because the $.serialize() function looks for all "properties" of form "this" having a key equals to "elements". But the input/select form control having its id="elements" seems to override that form property somehow, thus resulting in the serialization of an empty array of form elements :(

For example, attempting to serialize a form defined as such:

<form id='perioricTableSubmissionForm'>
  <input id="professor" name="professor"/>
  <select id="department" name="department">...</select>
  <select id="elements" name="elements[]" multiple>...</select>
  ...
</form>

Would return a blank string when calling

$('form').serialize();

because the serialize() method in jQuery does something like this:

...
var elements = $.prop(this, "elements");
...

This sounds like our old friend DOM property aliasing, which we can't fix. ​http://kangax.github.com/domlint/
