错误：“选择器未实现”

Question

我无法选择具有角度的元素。我必须做一些愚蠢的错误：

Error: selectors not implemented

forEach angular.js:110 
eventHandler 

Reproduced in this fiddle

我在做什么错：

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

导致的错误？我包括jQuery。这不应该工作吗？

Answer 1

这是因为jquery需要在之前引用角度。 JSFiddle注册了Angular 1.0.2 FIRST，然后添加了作为资源添加的jquery verson。

<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，选择将在angular.element()

Here's your fiddle, updated to reference the scripts in the right order (and altered slightly, see the comments)

工作，如果你没有JQuery的，您可以手动选择的DOM元素。这里

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