javascript - jQuery match part of class with hasClass

Question

I have several div's with "project[0-9]" classes:

<div class="project1"></div>
<div class="project2"></div>
<div class="project3"></div>
<div class="project4"></div>

I want to check if the element has a "project[0-9]" class. I have .hasClass("project") but I'm stuck with matching numbers.

Any idea?

You can use the startswith CSS3 selector to get those divs:

$('div[class^="project"]')

To check one particular element, you'd use .is(), not hasClass:

$el.is('[class^="project"]')

For using the exact /projectd/ regex, you can check out jQuery selector regular expressions or use

/(^|s)projectd(s|$)/.test($el.attr("class"))
