jQuery: Pass variable to :eq() does not work

rated 0 times [ 125] [ 1] / answers: 1 / hits: 21427 / 15 Years ago, thu, july 2, 2009, 12:00:00

I have been trying to find out why the following lines of code do not work:

$('#add-cloud > select').change(function() {

    var selected = parseInt($('#add-cloud select option:selected').val()); 

    $(#cloud-calculator table tr:eq(selected)).css(color, red);

});

If I change :eq(selected) to :eq(4) for example - works fine. How do you pass variable as an argument to :eq() ?

You have to concatenate your variable with your selector:

$(tr:eq(+selected+));
