我在 winjs.xhr 中检索聊天消息时遇到问题:
function getMessage() {
var time = MESSAGE_RETURNED.unixtime;
if (time == 0) {
time= window.parent.SESSION.unixtime;
}
WinJS.xhr({
url: "http://www.example.com/scripts/default.php?"
+ "action="+ACTIONS.GET_MESSAGE
+ "&username=" + window.parent.SESSION.username
+ "&session_id=" + window.parent.SESSION.session_id
+ "&unixtime=" + time
}).done(
function fulfilled(result) {
console.log("action=" + ACTIONS.GET_MESSAGE
+ "&username=" + window.parent.SESSION.username
+ "&session_id=" + window.parent.SESSION.session_id
+ "&unixtime=" + time);//CHECK INPUTS , ALL GREEN
if (result.status === 200) {
if (result.response.toString.length === 0) {
return false;
}//ALWAYS TRUE;
else {
console.log(JSON.parse(result.response));
}
} else {
document.getElementById("messagelogarea").value += result.status + "\r\n";
}
});
}
我正在尝试从 php.ini 检索 JSON。但是，当使用 WinJS.xhr 时，我返回的响应始终为空。如果将直接链接放入浏览器中，我将得到如下结果: (包含 3 条聊天消息的数组)
{
"message": [
{
"_id": "428",
"from_TBonlineusers_id": "00477",
"fromTBonlineusers_username": "GUEST_477",
"fromTBonlineusers_type": "GUEST",
"messagetype": "PUBLIC",
"message": "wat?xxwiii",
"chatmessagetime": "2012-11-16 15:36:06",
"unixtime": "1353098166"
},
{
"_id": "429",
"from_TBonlineusers_id": "00477",
"fromTBonlineusers_username": "GUEST_477",
"fromTBonlineusers_type": "GUEST",
"messagetype": "PUBLIC",
"message": "wat?xxwiii",
"chatmessagetime": "2012-11-16 15:42:42",
"unixtime": "1353098562"
},
{
"_id": "430",
"from_TBonlineusers_id": "00477",
"fromTBonlineusers_username": "GUEST_477",
"fromTBonlineusers_type": "GUEST",
"messagetype": "PUBLIC",
"message": "wat?xxwiiir",
"chatmessagetime": "2012-11-16 15:42:48",
"unixtime": "1353098568"
}
]
}
最佳答案
toString 是大多数对象的方法。
你的行result.response.toString.length应该是result.response.toString().length
