之前看到一个试题，要求用angularJs和Bootstrap写一个简单的计算器，通过百度，发现没有什么好的例子，所以呢，我就把自己写的一个例子发出来给大家。（大牛勿喷）

AngularJs代码:

var myApp=angular.module("myApp",[]); myApp.controller("myController",function($scope){   $scope.shuzi="";   $scope.jieguo=0;   $scope.num=function(num){     $scope.shuzi+=num;   }   $scope.js=function(){     $scope.jieguo=(eval($scope.shuzi));   }   $scope.reversal=function(){     if(eval($scope.shuzi)>0){       $scope.shuzi="-"+$scope.shuzi;     }else{       $scope.shuzi=$scope.shuzi.substring(1);     }   }    $scope.remove=function(){     $scope.shuzi="";     $scope.jieguo=0;   } })
