Question

I need to count all elements who has id like ‘hi*’.

For example, if we have markup below:

<div id="hi1"></div>
<div id="hi2"></div>

Num value has to be ‘2’.

In the web I have found this:

var num = $('.insttip:regex(id,'+ id[0] + '*').length;

But this is not working 🙁
Thank you!

var num = $('div[id^=hi]').length;

The ^ selector means starts with. Hope this helps
