jQuery Get all elements where class contains a number

Question

I want to get all elements that class contains a number, how can I do that?
I haven't tried anything because I don't really know how to think about it.

Answer 1

This might be related to this question: jQuery selector regular expressions

Using the regex functionality from this page, you should be able to do something like this:

$(':regex(class,.*[0-9].*)');

Answer 2

This can be done by iterating over all desired elements, keeping only those where the className attribute matches a given regex.

var divs = $('div');
var regex = /\d/;
var result = divs.filter(index => regex.test(divs[index].className));

result.each(index => console.log(result[index]));
