Question

js json赋值

var jsonstr="[{'phone':sjh}]";
dt=eval('('+jsonstr+')');
求问大佬那个sjh怎么赋值给phone

Answer 1

var sjh = 123456789
var jsonstr="[{'phone':sjh}]"
var dt=eval('('+jsonstr+')')
console.log(dt) // 输出结果：[{phone:123456789}]

eval是将字符串解析成js表达式并执行

Answer 2

var jsonstr="[{'phone':sjh}]";

dt=eval('('+jsonstr+')');

let phone = jsonstr[0].phone;
