錯誤：「選擇器未實現」

Question

我無法選擇具有角度的元素。我必須做一些愚蠢的錯誤：

Error: selectors not implemented

forEach angular.js:110 
eventHandler 

Reproduced in this fiddle

我在做什麼錯：

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

導致的錯誤？我包括jQuery。這不應該工作嗎？

Answer 1

這是因爲jquery需要在之前引用角度。 JSFiddle註冊了Angular 1.0.2 FIRST，然後添加了作爲資源添加的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> 

這樣Angular知道它可以使用JQuery而不是JQLite。一旦你這樣做，選擇將在angular.element()

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

工作，如果你沒有JQuery的，您可以手動選擇的DOM元素。這裏

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