这篇文章主要介绍了如何基于AngularJS实现工资计算器，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
js有什么特点
1、js属于一种解释性脚本语言；2、在绝大多数浏览器的支持下，js可以在多种平台下运行，拥有着跨平台特性；3、js属于一种弱类型脚本语言，对使用的数据类型未做出严格的要求，能够进行类型转换，简单又容易上手；4、js语言安全性高，只能通过浏览器实现信息浏览或动态交互，从而有效地防止数据的丢失；5、基于对象的脚本语言，js不仅可以创建对象，也能使用现有的对象。
具体如下：
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>
       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>
