Help me correct this if statement

JavaScript
1

I have a couple of h2’s. Some of them have spans inside, some don’t. I would like to add a class to those who has not.

I tried this:

$('h2').each(function(){
  if($(this).not(':has(span)')){
    $(this).addClass('font-size');
  } else {
    $(this).removeClass('font-size');
  }
});

and this:

  if($('h2').not(':has(span)')){
    $(this).addClass('font-size');
  } else {
    $(this).removeClass('font-size');
  }

But what this seem to do is add ‘font-size’ to all h2’s if one or more of them has spans inside.

You can use the filter method. Something like this:

// Look at all h2's
var $withSpans = $('h2').filter(function(){
    // If it has at least one span, save it
    if($('span', $(this)).length)
        return true
    // Otherwise remove it from the selector
    else
        return false
})
// Finally, add the class
$withSpans.addClass('font-size')

Or more succinctly:

$('h2').filter(function(){
    return $('span', $(this)).length
}).addClass('font-size')
