修改json字符串中的key值

 //原json 格式 {"id":"333","name":"xxxx"}

//将 json 字符串转换为 json 对象

var json = JSON.parse(jsonString); var value = "";

for (var i = 0;i<json.length;i++) {

value += "{\"id\":\""+json[i].id+"\",\"text\":\""+json[i].text+"\"},"

}

value = value.substr(0,value.length - 1);

转换后格式{"id":"333","text":"xxxx"}
