How to select jquery elements containing a certain character string?

Question

Say I have the following:

<div id="hellokat"></div>
<div id="hellodog"></div>
<div id="byekat"></div>
<div id="byedog"></div>

I know I can select divs individually with $('#hellokat') and $('hellodog'), but I want to select all divs containing "hello" at the beginning of their ids at the same time.

Wildcards in jQuery selectors

Simply use regular expressions in selectors:

$("div[id^=hello]").hide();
