Angular实现的进度条功能示例

本文实例讲述了Angular实现的进度条功能。分享给大家供大家参考，具体如下：

项目里需要一个进度条，所以就在网上查找资料学习，看到了网友“雪狼”的代码分享，写的很高明，很精练，很厉害，原文中的代码如下：

HTML部分：

<div ng-class="{progress: true, 'progress-striped': vm.striped}">
 <div ng-class="['progress-bar', vm.style]" ng-style="{width: vm.value + '%'}">
  <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>

JS部分：

'use strict';
angular.module('ngShowcaseApp').controller('ctrl.show.progress', function ($scope) {
 var vm = $scope.vm = {};
 vm.value = 50;
 vm.style = 'progress-bar-info';
 vm.showLabel = true;
});

这里结合自己的项目需要，自己改编了个简单的进度条，可以加在项目里面，进度条的开始和结束由自己决定。

1. js代码

var myApp = angular.module('myApp', []);
myApp.controller('main', ['$scope', '$interval', function($scope, $interval){
  var vm = $scope.vm = {};
  vm.value = 0;
  vm.style = 'progress-bar-danger';
  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代码

<div ng-class="{progress: true, 'progress-striped': vm.striped}" class="col-md-4">
   <div ng-class="['progress-bar', vm.style]" ng-style="{width: vm.value + '%'}">
      <div ng-if="vm.showLabel">{{vm.value}}%</div>
   </div>
</div>
<button class="btn btn-success" ng-click="count()">开始进度</button>

希望本文所述对大家AngularJS程序设计有所帮助。
