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()
和数据()
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.
