angularjs – 错误：“选择器未实现”

我无法选择有角度的元素。我必须犯一些愚蠢的错误：

function Root($scope) {
    $scope.elem = angular.element('div');
}

造成的错误：

Reproduced in this fiddle

我究竟做错了什么？我包括jQuery。这不是应该工作吗？

这是因为需要在角度之前引用jquery。 JSFiddle注册了Angular 1.0.2 FIRST，然后添加了jquery verson作为资源。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"></script>

这样Angular知道它可以使用JQuery而不是JQLite。一旦你这样做，选择器将工作在angular.element()

@L_502_1@

如果没有JQuery，可以手动选择DOM元素。

var div = document.querySelector('div');
$scope.elem = angular.element(div);
