Remove elements with only a space using jQuery

Question

Is there a way to remove this

using jQuery?

Answer 1

If you are trying to simply remove all empty P elements, or P's with only a single space, then you could do this:

$('p').map( function(){
  var html = $(this).html();
  if( !html.length || html == ' ' || html == String.fromCharCode(255) )
    return this;
}).remove();

This iterates through all of the P's on your page and if they match a certain criteria (they are empty or only have a whitespace) then it removes them from the DOM.

Also, by assigning our html content once to a local variable, it helps the script run faster. To look for non-breaking spaces I simply compare the contents to a string created from ASCII character code 255 (which is a non-breaking space).

jQuery's map() function can be great when a simple filter, or attribute comparison will not suffice.
