问题描述

我有angularjs指示找到与注入的角度子元素的DOM元素的麻烦。

I am having trouble with angularjs directives finding child DOM elements with the injected angular element.

例如我有一个指令,像这样:

For example I have a directive like so:

myApp.directive('test', function () {
    return {
        restrict: "A",
        link: function (scope, elm, attr) {
            var look = elm.find('#findme');
             elm.addClass("addedClass");
            console.log(look);
        }
    };
});

和HTML,例如:

<div ng-app="myApp">
    <div test>TEST Div
        <div id="findme"></div>
    </div>
</div>

我有权访问哪些是通过将一类到它proffed的元素。
但是试图访问一个子元素产生在var看空数组。

I have access to the element which is proffed by adding a class to it.However attempting to access a child element produces an empty array in the var look.

为什么东西那么微不足道工作不正常?

Why is something so trivial not working properly?

推荐答案

从:

找到() - 由标签名限于查找

所以,如果你不使用jQuery有棱有角,但依靠其jqlite实现,你不能做 elm.find('#someid')

So if you're not using jQuery with Angular, but relying upon its jqlite implementation, you can't do elm.find('#someid').

您有机会获得儿童()内容()数据()实现,所以通常可以找到变通的办法。

You do have access to children(), contents(), and data() implementations, so you can usually find a way around it.
