jQuery在获取属性值方面的性能

Question

Is there any difference in performence between these three below when it comes to getting element's attribute value?

a) attr() function

$('div').click(function() {
    var div_id = $(this).attr('id');
    // rest of the logic
});

b) event object's target property

$('div').click(function(e) {
    var div_id = e.target.id;
    // rest of the logic
});

c) pure JS approach

$('div').click(function() {
    var div_id = this.id;
    // rest of the logic
});

Answer 1

No doubt option c is way better as given with others :

$('div').click(function() {
   var div_id = this.id;
   // rest of the logic
});

because this is available in the browser itself and you are not using another method of any external library like the other two.
