Question

I would use an expression like this

$("a[href*='2']").offset().left

but for iframe’s elements …

I tried this:

$("#inside-slider").contents().attr("a[href*='2']").offset().left

but nothing.

(inside-slider is my iframe’s id)

Answer 1

This line:

$("#inside-slider").contents().attr("a[href*='2']").offset().left

Should be:

$("#inside-slider").contents().find("a[href*='2']").offset().left

You want to use .find, not .attr.
