Question

I am trying to set class to a variable. My code is:

var vtxt = $(this).attr("id");
$("('" + vtxt + "')").addClass("on");

It does not work this way. I’ve tried several things with no luck. What is the right format for adding a setting class to a variable?

Thank you

Answer 1

Do this:

var vtxt = $(this).attr('id');
$("#"+vtxt).addClass('on');

But, it’s worth noting that (given the above example) you can just do this and get the same result:

$(this).addClass('on');
