angularJS封装md5等加密模块
首页 >  Web前端 > AngularJS  > 2017年08月02日阅(3488)评(0

1.引入文件encrypt.js

2.注入模块

var myApp = angular.module('myApp',['Encrypt']);

3.引用

myApp.controller('myController', function($scope,Md5,Base64,Sha1){
  // MD5加密当前日期
  $scope.md5Value = Md5.hex_md5(new Date());
})

encrypt.js 文件内容如下:
