本篇文章主要介绍了angularjs实现柱状图动态加载的示例，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

一准备工作

1.引用文件

下面链接中有一个jquery.js文件，请在index.html中引用。

2.新建文件

新建一个js文件，编写指令。这也是我第一次写指令，指令可扩展性强，还很方便，当项目中重复使用的一些效果时可以通过指令来减少冗余的代码。

二代码编写

/**

 * 柱状图动态加载指令
 */
angular.module(&#39;studyApp.directives&#39;)
 .directive(&#39;progressPer&#39;, function ($compile,$timeout) {
  return {
   restrict: &#39;AE&#39;,
   scope: {
    progressData: &#39;=&#39;
   },
   template: &#39; <p class="progress-main" ng-repeat="item in progressData">&#39;+
   &#39;<p class="progress-data">&#39;+
   &#39;<span>{{item.name}}</span>&#39;+
   &#39;<p class="skillbar clearfix " data-percent={{item.width}}>&#39;+
    &#39;<p class="skillbar-bar"></p>&#39;+
     &#39;<p class="skill-bar-percent">{{item.sum}}</p>&#39;+
    &#39;</p>&#39;+
   &#39;</p>&#39;+
   &#39;<p class="progress-rate">{{item.percent}}</p>&#39;+
   &#39;</p>&#39;,
   replace: true,
   transclude: true,
   link: function (scope, element, attrs) {
    $compile(element.contents())(scope.$new());
    $timeout(function() {
     jQuery(&#39;.skillbar&#39;).each(function(){
      jQuery(this).find(&#39;.skillbar-bar&#39;).animate({
       width:jQuery(this).attr(&#39;data-percent&#39;)
      },1000);
     });
    });
   }
  }
 });
