URL带参数json传递进行解析

注意参数格式是要加密的：

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" />

    <title>URL带参数json传递进行解析</title>

    </head>

    <body>

    <script>

      var common = {

          getQueryString : function(name){

            var reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');

            var r = '';

            try{

                r = location.href.split('?')[1].match(reg);

            }catch(err){}

            if (r != null && r != 'undefined') {

                return unescape(r[2]);

            }

            return null;

          }

      }

      // 这是url上的   ?userpar=token%3dxxxx%26identity%3d123%26sysrole%3d1%26showMenu%3d0%2c1%2c2%2c3%26showColumn%3d0%2c1

      var userpar = common.getQueryString('userpar');

      console.log('参数：'+userpar)

      //这是解析后的  token=xxxx&identity=123&sysrole=1&showMenu=0,1,2,3&showColumn=0,1

      console.log("userpar里的值:    "+userpar)

      var newArr = userpar.split('&');

      //["token=xxxx", "identity=123", "sysrole=1", "showMenu=0,1,2,3", "showColumn=0,1"]

      console.log(newArr)

      // 数据整理

      var params = [];

      var object = {}

      for(var i in newArr){

        var obj = {}

        key = newArr[i].split('=')[0];

        value = newArr[i].split('=')[1];

        obj[key] = value;

        object =  Object.assign(object,obj); //追加json

      }

      // 进行取值

      // {token: "xxxx", identity: "123", sysrole: "1", showMenu: "0,1,2,3", showColumn: "0,1"}

      console.log(object)

    </script>

</body>

</html>

在VUE中当用到split() 会提示split 没定义，解决办法，在split()前加上toString()即可：

  var newArr = userpar.toString().split('&');
