一、将JSON字符串为JS对象
在JS中,如果直接输入
var arr = {arr:[1,2,3]};
返回的是一个object对象 因此如果我们需要将其转换为JSON,可以用如下方式进行转换
var json = '{"arr":1}';
console.log("json的类型"+typeof json)
var json = JSON.parse(json);
console.log("json的类型="+typeof json)
console.log("json的值="+json)
在大括号{}外部加入单引号,内部的字段arr加入双引号
再进行调试输出我们可以发现
二、将JS对象转换为JSON字符串
JSON.stringify()
- 可以将一个JS对象转换为JSON字符串
- 需要一个js对象作为参数,会返回一个JSON字符串
var obj3 = {name:"猪八戒" , age:28 , gender:"男"};
console.log("obj3的类型="+typeof obj3);
var obj3 = JSON.stringify(obj3);
console.log("obj3的类型="+typeof obj3);
