Is there a way to select all id\'s with jQuery with a prefix \"my\" and a suffix \"0-9\". Something like these $(\"#my$1-4\") or is it just possible with a loop ?
Assuming you don't have millions of elements that start with "my", you could do:
$('[id^=my]').filter(function() { return this.id.matches(/\d/) && this.id.length == 3 })
This grabs all elements that have an id starting with "my", contain a number, and are only 3 characters long (so "my54" will not match but "my6" will)
