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?

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()

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.

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

Nothing from this examples , works for me 

for (var i = 0; i < res.results.length; i++) {
        $('#list_tags').append('<li class="dd-item" id="'+ res.results[i].id + '"><div class="dd-handle root-group">' + res.results[i].name + '</div></li>');
}

    $('.dd-item').click(function () {
    console.log($(this).attr('id'));
    });

$(".class").click(function(){
    alert($(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); 
});

Use "attr" method in jquery.

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