How to select an element by classname using jqLite?

Lior picture Lior · Jun 24, 2013 · Viewed 148.7k times · Source

I'm trying to remove jquery from my Angular.js app in order to make it lighter, and put Angular's jqLite instead. But the app makes heavy use of find('#id') and find ('.classname'), which are not supported by jqLite, only 'tag names' (as per documentation)

wondered what do u feel would be the best approach to change it. One approach I thought about is to create custom HTML tags. for example: change
<span class="btn btn-large" id="add-to-bag">Add to bag</span>

to

<a2b style="display:none;"><span class="btn btn-large" >Add to bag</span></a2b>

and

$element.find('#add-to-bag') 

to

$element.find('a2b')

Any thoughts? other ideas?

thanks

Essentially, and as-noted by @kevin-b:

// find('#id')
angular.element(document.querySelector('#id'))

//find('.classname'), assumes you already have the starting elem to search from
angular.element(elem.querySelector('.classname'))

Note: If you're looking to do this from your controllers you may want to have a look at the "Using Controllers Correctly" section in the developers guide and refactor your presentation logic into appropriate directives (such as <a2b ...>).
