這是我第一次嘗試向API發出跨域Ajax請求。我正在使用jQuery進行調用,並試圖將返回的某些項目放到頁面上。jQuery Ajax請求(CORS)返回undefined
這裏的要求:
$.ajax({
type: 'POST',
url: 'http://magicseaweed.com/api/APIKEY/forecast/?spot_id=665',
contentType: "text/plain",
dataType: "json",
xhrFields: {
withCredentials: false
},
success: function(data) {
timestamp = data.localTimestamp;
alert(timestamp);
},
error: function() {
alert("aw crap");
}
});
這裏的響應:
[{
timestamp: 1366902000,
localTimestamp: 1366902000,
issueTimestamp: 1366848000,
fadedRating: 0,
solidRating: 0,
swell: {
minBreakingHeight: 1,
absMinBreakingHeight: 1.06,
maxBreakingHeight: 2,
absMaxBreakingHeight: 1.66,
unit: "ft",
components: {
combined: {
height: 1.1,
period: 14,
direction: 93.25,
compassDirection: "W"
},
primary: {
height: 1,
period: 7,
direction: 83.37,
compassDirection: "W"
},
secondary: {
height: 0.4,
period: 9,
direction: 92.32,
compassDirection: "W"
},
tertiary: {
height: 0.3,
period: 13,
direction: 94.47,
compassDirection: "W"
}
}
}]
目前,我只是想獲得時間戳字符串中的一個警告框來顯示。
alert(timestamp);
由於未定義而返回。我的錯誤在哪裏?
數組什麼警報'輸出(數據)',甚至更好'的console.log(JSON.stringify (data))' - nvm,剛剛看到你的數據結構。 @Abdennour TOUMI答案正確 – JorgeObregon
看起來響應是一個數組。你有沒有試過'data [0] .localTimestamp' –
