Is it possible to have multiple click events on one elements, when using different selectors?

<button id="test" class="testclass">test</button>
<button id="test2" class="testclass2">test 2</button>

//only B
$('.testclass')[0].click(function(){alert('A');});
$('#test').click(function(){alert('B');});

// A and B
$('#test2').click(function(){alert('A2');});
$('#test2').click(function(){alert('B2');});

Yes, that’s perfectly possible.

However, you’re misusing jQuery.
Writing $(...)[0] gives you the first raw DOM element in the set.
It isn’t a jQuery object, so you can’t call jQuery’s click method on it.

Instead, you should call the eq method, which returns a jQuery object containing a single element from the original set.

Change it to $('.testclass').eq(0).click(...)
