Question

I’ve got this:

<h1 id="test" class="test">

and in a script part this:

alert($('#test').id)
alert($('.test').id)

jQuery is definitely loaded. But I get undefined in the alert box – both times. If I use the regular getElementById, it works and shows test.

What the heck is wrong (with me)

here’s an example http://jsfiddle.net/tF6bd/

Answer 1

change:

alert($('#test').id)

to:

alert($('#test').attr('id'))

or:

alert($('#test')[0].id)

for jQuery objects you should use attr() method.
