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" ng-model="vm.value"/></label> <button ng-click="vm.value=0">0%</button> <button ng-click="vm.value=20">20%</button> <button ng-click="vm.value=60">60%</button> <button 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"> <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}"> <div ng-class="['progress-bar', vm.style]" ng-style="{width: vm.value + '%'}"> <div ng-if="vm.showLabel">{{vm.value}}%</div> </div> </div> <button ng-click="count()">开始进度</button>
