我正在使用以下代码从这个 JSON 中获取一些元素，但似乎没有任何效果。有人知道我做错了什么吗？（我花了很长时间试图弄清楚）。
$(document).ready(function() {
$.getJSON('http://free.worldweatheronline.com/feed/weather.ashx?q=Stockholm&format=json&num_of_days=2&key=e8536d3a52101433121710', function(Wdata) {
$.each(Wdata.data, function() {
$('<div id="test"></div>').append(
this.weather[0].date;
).appendTo('body');
});
});
});
我的 HTML 看起来像这样：
<!doctype html>
<html lang="se">
<head>
<meta charset="utf-8" />
<title>Title of This Web Page</title>
<script src="scripts\jquery-1.8.2.js" type="text/javascript"></script>
<script src="scripts\js.js" type="text/javascript"></script>
</head>
<body>
<div id="test">
</div>
</body>
</html>
JSON 看起来像这样：
{
"data": {
"current_condition": [ … ],
"request": [ … ],
"weather": [
{
"date": "2012-10-17",
