Serialize form not working in jQuery

Something else that prevents serializeArray() from serializing properly is disabled inputs. serializeArray does not serialise disabled inputs, in much the same way that disabled inputs are not submitted with the form.

A successful control is "valid" for submission.

• Controls that are disabled cannot be successful.

Please add a name to your input field:

<input type='text' name='give_some_name' />

In this fiddle I have added a name and it is working fine.

You have to give your form elements names!

This is independent of jQuery. Every form element must have a name to be considered for form submission as successful control:

A successful control is "valid" for submission. Every successful control has its control name paired with its current value as part of the submitted form data set. A successful control must be defined within a FORM element and must have a control name.

jQuery just ignores those elements that don't have a name (or, depending on how it gets the elements, it might not even see them as the form itself has no reference to them).

I think the problem is that you're trying to select form like

$("form");

But this is equivalent to

getElementsByTagName("form");

This returns an array of objects.
So, instead you can use the #id selector, or use the index to access the form. Hope this helps.
