其实在ng中最让人印象深刻的就是数据的双向绑定，在html中就完成了很多操作。大概用到的就是控制器视图服务等，没有分模块写控制器，代码如下：
<html ng-app = "myApp"> <head> <title>工资计算器ng</title> <script src= "angular.js"></script> </head> <body> <div ng-controller = "MyController"> 税前工资：<input ng-model="salary.shuiqiangonngzi"></input> 税后工资：<input ng-model="salary.shuihougongzi" ng-readonly = true></input><button ng-click = "calulate()">计算</button></br> 缴纳基数：社保<input ng-model="salary.shebao"></input> 公积金<input ng-model="salary.gongjijin"></input></br>        缴纳比例：       个人                单位 </br> 养老：<input ng-model="salary.gerenyanglaobili"></input>{{salary.gerenyanglao| number:2}}<input ng-model="salary.danweiyanglaobili"></input>{{salary.danweiyanglao| number:2}}</br> 医疗：<input ng-model="salary.gerenyiliaobili"></input>{{salary.gerenyiliao| number:2}}<input ng-model="salary.danweiyiliaobili"></input>{{salary.danweiyiliao| number:2}}</br> 失业：<input ng-model="salary.gerenshiyebili"></input>{{salary.gerenshiye| number:2}}<input ng-model="salary.danweishiyebili"></input>{{salary.danweishiye| number:2}}</br> 工伤：<input ng-model="salary.gerengongshangbili"></input>{{salary.gerengongshang| number:2}}<input ng-model="salary.danweigongshangbili"></input>{{salary.danweigongshang| number:2}}</br> 生育：<input ng-model="salary.gerenshengyubili"></input>{{salary.gerenshengyu| number:2}}<input ng-model="salary.danweishengyubili"></input>{{salary.danweishengyu| number:2}}</br> 公积金：<input ng-model="salary.gerengongjijinbili"></input>{{salary.gerengongjijin| number:2}}<input ng-model="salary.danweigongjijinbiili"></input>{{salary.danweigongjijin | number:2}}</br> 个人缴税：{{salary.gerenjiaoshui| number:2}}单位缴税：{{salary.danweijiaoshui | number:2}}</br> 个人所得税：{{salary.gerensuodeshui| number:2}} <p>默认数据是北京市计算比例。</p> <h5>{{theTime}}</h5> </div> <script type = "text/javascript"> var app = angular.module("myApp", []);
