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开发者_开发百科 the whole list.

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();

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.
