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

Try the Attribute Starts With Selector. As a bonus, there is no need for the extra if.

$('#dialog li[class^="C"]').each(function() {
    // do something
});
