Js 中json简单处理

Json2.js下载地址 json常用处理

Json字符串

var str = '{"code":10,"msg":"codemsg","data":{"data1":"111","data2":"222","array":["11","22","33","44"]}}';

Json对象

var map = {
        code:10,
        msg:'codemsg',
        data: {
            data1: '111',
            data2: '222',
            array: arr
        }
    };

以下代码是在引用json2.js的前提下

1.Json字符串转Json对象

var str = '{"code":10,"msg":"codemsg","data":{"data1":"111","data2":"222","array":["11","22","33","44"]}}';

//js 自带eval 处理
//eval() 函数可计算某个字符串，并执行其中的的 JavaScript 代码。
var obj = eval("(" + str + ")");

//Json2.js 处理
var obj2 = JSON.parse(str);

2.Json 对象转Json字符串

　　var map = {
        code:10,
        msg:'codemsg',
        data: {
            data1: '111',
            data2: '222',
            array: arr
        }
    };
    var param = JSON.stringify(map);
    console.log(param);
