Question

I have several classes that I want to select .group1-1 .group1-2 .group1-3, each one of these has 50 elements under it.

Is there a way to select all classes that start with group1 (so I end up selecting group1-1, group1-2, group1-3), something like $(".group1"+*)

You can also use something along the lines of this if you’d like to avoid regex:

$("[class^='group1-']").click(function () {
    var groupNumber = $(this).attr('class').split('-')[1];
    alert('Yep, you clicked group1-' + groupNumber); 
});
