日常开发记录-JavaScript中字符串(string)转json的方法

let json = eval("(" + str + ")");

代码演示：

let str = `{
    "statusCode": "300",
    "message": "未登陆",
    "callback": "",
    "dotype": {
        "reload": "currentTab",
        "reloadId": "",
        "close": "",
        "openUrl": "",
        "openId": ""
    },
    "data": ""
}`

let json = eval("(" + str + ")");
console.log(json)
console.log("类型--" + typeof json)

输出：

{
  statusCode: '300',
  message: '未登陆',
  callback: '',
  dotype: {
    reload: 'currentTab',
    reloadId: '',
    close: '',
    openUrl: '',
    openId: ''
  },
  data: ''
}
类型--object
