jQuery check if element has a class beginning with some string

Question

I need to loop through some elements in the page and then, for each one, if it had a class beginning with, for example, \"C\", do something.

$(\'#dialog li\').e         


        

Answer 1

For more elaborate filters than "starts with" you can use the filter() function:

$('#dialog li').filter( function() { 
  // return true for every element that matches your condition
  return this.className.match(/^c/) != null;
}).each(function(){
  //do something
}
