jQuery pseudo classes

Is this correct?

var deleteIndex = 3;
$("ol li:nth-child(deleteIndex)").remove();

For some reason, this doesn't seem to work. Executing this clears the whole list.

You need to use:

var deleteIndex = 3;
$("ol li:nth-child(" + deleteIndex + ")").remove();

so that deleteIndex is converted to 3. Or if 3 is a constant used only here, you could just use 3.

It really works.

You are adding the literal text 'deleteIndex' into the jQuery selector rather than the number contained in the variable. Try this instead:

var deleteIndex = 3;
$("ol li:nth-child(" + deleteIndex + ")").remove();

May be if you try this: var deleteIndex = 3; $("ol li:eq(deleteIndex)").remove();
