I need to strip all letters from a h1 with a certain class so that

<h1 class="hole">1st Hole</h1>

Becomes 

<h1 class="hole">1</h1>

And this would replicate on each page, 2nd Hole, 3rd Hole etc

  • Your question and title conflict. Do you want to remove all letters (`a-z` and `A-Z`), or all non-numeric (i.e. digit) characters (anything that isn't `0-9`)? You example removes a space character, which indicates the latter, which agrees with the title but conflicts with the question's content. – ajp15243 Feb 02 '14 at 07:59

You can use the receiver function of .text() to accomplish your job efficiently. And additionally ^\d matches the non-numeric, so we are just replacing the matched non-numeric with ''

Try,

$('h1.hole').text(function(_,xText){
 return xText.replace(/[^\d]/g, ''); 
})

    Using all-capitals is usually interpreted as shouting when in an online setting; I was wondering *why* you you were shouting 'DEMO' instead of simply using normal writing conventions, 'Demo,' for example. – David Thomas Feb 02 '14 at 08:52

You could also strip all the non-digit characters (\D or [^0-9]):

'abc123cdef4567hij89'.replace(/\D/g, ''); // returns '123456789'

Here is an example

$('h1').each(function(){
    $(this).html($(this).html().replace(/[^0-9\.]/g, ''));
});
