如何在JSON對象上循環？

Question

我有這樣的JSON對象：

{"time":"123456789", "raw":"chat_history", "data":{ 
"msg":[ 
{"time":1111111111, "user":"user1", "text":"text from user1"}, 
{"time":2222222222, "user":"user2", "text":"text from user2"}, 
{"time":3333333333, "user":"user3", "text":"text from user3"}, 
{"time":4444444444, "user":"user4", "text":"text from user4"} 
] 
}} 

我必須爲data.msg的循環元素創建和打印：

11111111111 - user1 - text from users1 
22222222222 - user2 - text from users2 
33333333333 - user3 - text from users3 
44444444444 - user4 - text from users4 

：

我會與打印這些結果

你能幫我嗎？

非常感謝您

Answer 1

for(var i = 0; i < data.msg.length; i++) 
{ 
    var row = data.msg[i]; 
    print(row.time + ' - ' + row.user + ' - ' + row.text); 
} 

Answer 2

var msg = yourJsonObject.data.msg; 

for (var i = 0, len = msg.length; i < len; i++) { 
    // document.write only for example 
    document.write(msg[i].time + ' - ' + msg[i].user + ' - ' + msg[i].text); 
}
