Question

i need your help with an regex in Javascript, again.

Sometimes i have empty p-Tags in the DOM and i will remove them all.

Some look like:

<p></p>

others like:

<p> </p>

I think for an regex pro is this very lame, but i’m not good with it 🙁

so thanks in advance 🙂

You don’t need to use regex for something this simple. Most likely you need to iterate over all the ‘p’ elements anyway. Something like this works:

http://jsfiddle.net/mqchen/3pV2P/

$('p').each(function(index, item) {
    if($.trim($(item).text()) === "") {
        $(item).slideUp(); // $(item).remove();
    }
});
