Question

There is a jQuery :gt() selector which allows to select all elements at an index greater than index within the matched set.

I can use it like this:

$(this).find('a:gt(30)');

The problem is that I’m using a var instead:

var opt = $("#div").text();

How do I set the :gt() selector next to the variable:

var opt = $("#div").text();

$(this).find(opt:gt(30));

This doesn’t seem to work.

Answer 1

You just need to use string concatenation.

$(this).find(opt + ":gt(30)")

If opt has a value of, for example, "a". Then the expression opt + ":gt(30)" will evaluate to "a:gt(30)".

You need to be careful that opt is a valid selector.
