Question

I want to add a rel attribute of the element matching the array, so for example the array is:

var targetVal = ['1','2','4'];

And 5 elements with the same class:

<a class="link" href="1.html">
<a class="link" href="2.html">
<a class="link" href="3.html">
<a class="link" href="4.html">
<a class="link" href="5.html">

I want to target the 2nd, 3rd and 5th line with a rel attribute.

 $(".link").each(function(index) {
       $(this).attr("rel", "group");
    });

How can I make the above script index through based on the array?

Answer 1

var targetVal = ['1','2','4'];

$.each(targetVal, function(index, val) {
       console.log(val);
       $('.link').eq(val).attr("rel", "group");
});
