Remove elements with only a   space using jQuery

Question

Is there a way to remove this

<p> </p>

using jQuery?

Answer 1

Try:

$('p')
    .filter(function() {
        return $.trim($(this).text()) === '' && $(this).children().length == 0
    })
    .remove()

What that does is it finds all the <p>s that have nothing in them, and removes them from the DOM.

Answer 2

As Greg mentions above, testing the trimmed .text() will remove paragraphs w/ no text, but do have a self-contained element like the <img> tag. To avoid, trim the .html() return. As text is considered a child element in the DOM, you'll be set.

$("p").filter( function() {
    return $.trim($(this).html()) == '';
}).remove()

Answer 3

This could be a better solution for CMSs. Some rich text editors add   inside empty paragraphs.

    $("p").filter( function() {

        var html = $(this).html();

        if(html == '' || html == ' ')
            return true;

    }).addClass('emptyP');
