JSON.parse()和JSON.stringify()的用法及區別

JSON.parse()是從字符中解析出json對象：

var str = '{"overMoney":0,"castCategoryId":9,"castFarmId":""}';
console.log(JSON.parse(str))

{overMoney: 0, castCategoryId: 9, castFarmId: ""}

而JSON.stringify()剛好相反 是從對象中解析出字符串：

var obj = {"overMoney":0,"castCategoryId":9,"castFarmId":""};
console.log(JSON.stringify(obj))

{"overMoney":0,"castCategoryId":9,"castFarmId":""}

ok  妥妥搞定啦
