專案裡需要一個進度條，所以就上網找資料學習，本文就跟大家分享Angular實作進度條功能碼，希望能幫助大家。

HTML部分：

<div ng-class="{progress: true, &#39;progress-striped&#39;: vm.striped}">
 <div ng-class="[&#39;progress-bar&#39;, vm.style]" ng-style="{width: vm.value + &#39;%&#39;}">
  <div ng-if="vm.showLabel">{{vm.value}}%</div>
 </div>
</div>
<h3>选项</h3>
<label>进度：<input type="number" class="form-control" ng-model="vm.value"/></label>
<button class="btn btn-primary" ng-click="vm.value=0">0%</button>
<button class="btn btn-primary" ng-click="vm.value=20">20%</button>
<button class="btn btn-primary" ng-click="vm.value=60">60%</button>
<button class="btn btn-primary" ng-click="vm.value=100">100%</button>
<hr/>
<label>斑马纹<input type="checkbox" ng-model="vm.striped"/></label>
<label>文字<input type="checkbox" ng-model="vm.showLabel"/></label>
<hr/>
<label>风格：
 <select ng-model="vm.style" class="form-control">
  <option value="progress-bar-success">progress-bar-success</option>
  <option value="progress-bar-info">progress-bar-info</option>
  <option value="progress-bar-danger">progress-bar-danger</option>
  <option value="progress-bar-warning">progress-bar-warning</option>
 </select>
</label>

#這裡結合自己的項目需要，自己改編了個簡單的進度條，可以加在專案裡面，進度條的開始和結束由自己決定。

1. js程式碼

var myApp = angular.module(&#39;myApp&#39;, []);
myApp.controller(&#39;main&#39;, [&#39;$scope&#39;, &#39;$interval&#39;, function($scope, $interval){
  var vm = $scope.vm = {};
  vm.value = 0;
  vm.style = &#39;progress-bar-danger&#39;;
  vm.showLabel = true;
  vm.striped = true;
  $scope.selectValue = function (){
    console.log(vm.style);
  };
  var index = 0;
  var timeId = 500;
  $scope.count = function(){
    var start = $interval(function(){
      vm.value = ++index;
      if (index > 99) {
        $interval.cancel(start);
      }
      if (index == 60) {
        index = 99;
      }
    }, timeId);
  };
}]);

2. html程式碼

<div ng-class="{progress: true, &#39;progress-striped&#39;: vm.striped}" class="col-md-4">
   <div ng-class="[&#39;progress-bar&#39;, vm.style]" ng-style="{width: vm.value + &#39;%&#39;}">
      <div ng-if="vm.showLabel">{{vm.value}}%</div>
   </div>
