如何在 AngularJS 中使用 jQuery [英] How to use jQuery in AngularJS

问题描述

我正在尝试使用简单的 jQuery UI.我已经包含了所有内容，并且有这个简单的脚本:

和

<div id="slider"></div>

我的包括:

<script type="text/javascript" src="js/jquery-1.10.2.js"></script><script type="text/javascript" src="js/jquery-ui-1.10.4.custom.min.js"></script><script type="text/javascript" src="js/jquery.easing.1.3.js"></script><script type="text/javascript" src="js/ayaSlider.js"></script><script type="text/javascript" src="js/bootstrap.min.js"></script><script type="text/javascript" src="js/angular.min.js"></script><script type="text/javascript" src="js/angular-route.min.js"></script><script type="text/javascript" src="js/app.js"></script>

但是当我打开页面时没有滑块.根据角度文档:

<块引用>

如果 jQuery 可用，angular.element 是 jQuery 的别名功能.如果 jQuery 不可用，angular.element 委托给Angular 内置的 jQuery 子集.

但是，我真的不明白如何使用 angular.element 并且没有示例.

更新:我设法让滑块出现在屏幕上，但它不起作用，我无法更改值或使用它做任何事情.

解决方案

理想情况下，您可以将其放在指令中，但也可以将其放在控制器中.http://jsfiddle.net/tnq86/15/

 angular.module('App', []).controller('AppCtrl', function ($scope) {$scope.model = 0;$scope.initSlider = 函数 () {$(函数(){//等待加载事件触发，以便所有资源都可用$scope.$slider = $('#slider').slider({幻灯片:$scope.onSlide});});$scope.onSlide = 函数 (e, ui) {$scope.model = ui.value;$scope.$digest();};};$scope.initSlider();});

指令方法:

HTML

JS

 angular.module('App', []).directive('slider', function (DataModel) {返回 {限制:'A'，范围:真实，控制器:函数($scope，$element，$attrs){$scope.onSlide = 函数 (e, ui) {$scope.model = ui.value;//或者在模型上设置//DataModel.model = ui.value;//添加到角度摘要循环$scope.$digest();};},链接:功能(范围，EL，属性){变量选项 = {幻灯片:scope.onSlide};//在加载时设置滑块angular.element(document).ready(function () {scope.$slider = $(el).slider(options);});}}});

我还建议您查看 Angular Bootstrap 的源代码:https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js

您也可以使用工厂来创建指令.这为您提供了极大的灵活性，可以围绕它集成服务以及您需要的任何依赖项.

I am trying to use simple jQuery UI. I've included everything and I have this simple script:

<script>
  $(function() {
    $( "#slider" ).slider();
  });
</script>

and

<div id="slider"></div>

My includes:

<script type="text/javascript" src="js/jquery-1.10.2.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.10.4.custom.min.js"></script>
<script type="text/javascript" src="js/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="js/ayaSlider.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript" src="js/angular.min.js"></script>
<script type="text/javascript" src="js/angular-route.min.js"></script>
<script type="text/javascript" src="js/app.js"></script>

But when I am opening the page there is no slider. According to documentation of angular:

If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery.

However, I don't really understand how can I use angular.element and there is no example.

Update: I managed to have the slider on the screen but it does not work, I cannot change values or do something with it.

解决方案

Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/

  angular.module('App', [])
    .controller('AppCtrl', function ($scope) {

      $scope.model = 0;

      $scope.initSlider = function () {
          $(function () {
            // wait till load event fires so all resources are available
              $scope.$slider = $('#slider').slider({
                  slide: $scope.onSlide
              });
          });

          $scope.onSlide = function (e, ui) {
             $scope.model = ui.value;
             $scope.$digest();
          };
      };

      $scope.initSlider();
  });

The directive approach:

HTML

<div slider></div>

JS

  angular.module('App', [])
    .directive('slider', function (DataModel) {
      return {
         restrict: 'A',
         scope: true,
         controller: function ($scope, $element, $attrs) {
            $scope.onSlide = function (e, ui) {
              $scope.model = ui.value;
              // or set it on the model
              // DataModel.model = ui.value;
              // add to angular digest cycle
              $scope.$digest();
            };
         },
         link: function (scope, el, attrs) {

            var options = {
              slide: scope.onSlide  
            };

            // set up slider on load
            angular.element(document).ready(function () {
              scope.$slider = $(el).slider(options);
            });
         }
      }
  });

I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js

You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.
