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; } })
