Select element by class or ID

Question

I am working on an ASP.NET page in which I generate some JavaScript code based on values in a database.

For example, in the database there might be the formula sum([#itemA]), which would evaluate to something like $('#itemA').change(function(){ sum(this); });.

I know that I can select elements using jQuery selectors such as $('[id*=itemA]') or $('[class*=itemA]'), but I am wondering if there is any way to combine these selectors so that any element with either a class or an ID of itemA would be selected.

Right now in my code I am just using if/else blocks to deal with ID's or classes, but if there is an easier implementation, I would love to use it.

I looked at the jQuery documentation and googled around a bit, but I didn't see anything that answered my question.

Thanks in advance!

That will work. I totally forgot CSS selectors were applicable. — Paul Woidke, Mar 25 '13 at 16:02

This should do the trick

$('[id*=itemA], [class*=itemA]')

For more details, take a look to official jquery documentation

This is the correct answer. OP is looking for either class OR id. Not class within an id. – Johan Mar 25 '13 at 15:59
This is perfect. I've been so focused on the Javascript so much that I totally forgot to think in terms of CSS selectors. – Paul Woidke Mar 25 '13 at 16:01

Use multiple selectors like

    $('.class1, .class2....., .classn')

You can literally use anything like ID names, class names or selectors like you specified separated by commas

Like in css, when selectors are separated by ,they are cumulated :

var elements = $('[id*=itemA], [class*=itemA]')

This will not work, it will select only [class*=itemA] that are in [id*=itemA] – Dan Mar 25 '13 at 16:02
Yeah I miss the comma – Johnny5 Mar 25 '13 at 16:04
