如何使用jqLit​​e通过类名选择元素? [英] How to select an element by classname using jqLite?

问题描述

我正在尝试从Angular.js应用中删除jquery，以使其更轻巧，而改用Angular的jqLit​​e.但是该应用程序大量使用了jqLit​​e不支持的find('#id')和find('.classname')，仅使用了标签名称"(根据文档)

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)

想知道您认为改变它的最佳方法是什么.我考虑过的一种方法是创建自定义HTML标签.例如: 更改
<span class="btn btn-large" id="add-to-bag">Add to bag</span>

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>

到

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

和

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

到

$element.find('a2b')

有什么想法吗?其他想法?

Any thoughts? other ideas?

谢谢

推荐答案

本质上，由@ kevin-b指出:

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'))

注意::如果您希望从控制器中执行此操作，则可能需要查看

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 ...>).
