jQuery将此作为函数参数传递

Question

HTML

<input type="button" id="1" class="add" value="+" title="Add" onclick="set(this);"/>

JS

function set(obj){
   alert(obj.id);
}

The above code is not working.

What I Require

I need to pass the id attribute of the button in the onclick function. Is there any way I could achieve this.

Answer 1

Your html should be

 <input type="button" id="1" class="add" value="+" title="Add" onclick="set(this.id);"/>

and write java script function as

function set(id)
   {
   alert(id);
   }

Answer 2

Your title mentions jQuery, but you're working with a JS solution. If you want to do this with jQuery:

HTML:

<input type="button" id="1" class="add" value="+" title="Add" />

JS:

$("#1").click(function(){alert(this.id);});
