如何知道在jquery中点击了哪个id？

Question

I want to know that which button has been clicked in jquery. I have the html file:

<div class="row">
    <div class="col-md-6">
        <div class="well " id="option_a">
        </div>
    </div>
    <div class="col-md-6">
        <div class="well " id="option_b">
        </div>
    </div>
</div>
<div class="row">
    <div class="col-md-6">
        <div class="well " id="option_c">
        </div>
    </div>
    <div class="col-md-6">
        <div class="well " id="option_d">
        </div>
    </div>
</div>

I need to know which option has been clicked?

Answer 1

Assuming you are binding event with element with class " well "

You can add code like following

$(".well").click(function(){
     var id = $(this).attr("id");
});

Answer 2

Here is my suggestion:

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

And here is the jsfiddle:

There is alert instead of console.log and the div containers have red background color with width and height each 100px for better visualization of the clicks.
