对象转化为json字符串

要将对象转化为JSON字符串，可以使用JSON.stringify()方法。这个方法将对象转化为字符串表示形式。例如，如果有一个对象如下：
{"name":"张三","age":"23","sex":"男"}
可以使用JSON.stringify()方法将其转化为JSON字符串：
var obj = {"name":"张三","age":"23","sex":"男"};
var jsonStr = JSON.stringify(obj);
console.log(jsonStr);
输出结果将是：
{"name":"张三","age":"23","sex":"男"} \[1\]
