一个基于angularJS的工资计算器

先看界面：

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>
        &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp缴纳比例：&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp个人&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp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>

        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}}
