jquery: get id from class selector

Is there any way that I can get the id of an element from something like:

<a href="#" class="test" id="test_1">Some text</a>
<a href="#" class="test" id="test_2">Some text</a>
<a href="#" class="test" id="test_3">Some text</a>

and then I bind

$('.test')

so when I click one of the elements I get back the id?

Doh.. If I get you right, it should be as simple as:

$('.test').click(function() {
  console.log(this.id);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a href="#" class="test" id="test_1">Some text</a>
<a href="#" class="test" id="test_2">Some text</a>
<a href="#" class="test" id="test_3">Some text</a>

You can just access the id property over the underlaying dom node, within the event handler.

Use "attr" method in jquery.

$('.test').click(function(){
    var id = $(this).attr('id');
});

When you add a click event, this returns the element that has been clicked. So you can just use this.id;

$(".test").click(function(){
   alert(this.id); 
});

As of jQuery 1.6, you could (and some would say should) use .prop instead of .attr

$('.test').click(function(){
    alert($(this).prop('id'));
});

It is discussed further in this post: .prop() vs .attr()

Be careful if you use fat arrow functions as you will get undefined for this.id Wasted 10 minutes today wondering what the hell was going on
