jQuery中的XML解析对我似乎不起作用 [英] XML parsing in jquery doesn't seem to work for me
问题描述
我有一个静态html页面weather.html
I have a static html page weather.html
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
type: "GET",
url: "http://www.google.com/ig/api?weather=Delhi",
dataType: "xml",
success: parseXml
});
});
function parseXml(xml) {
$(xml).find("weather").each(function() {
alert($(this).attr("temp_c"));
});
}
</script>
</head>
<body>
</body>
</html>
当我检查槽中的萤火虫时，似乎没有在页面中显示警报，
The alert doesn't seem to get displayed in the page when i inspected trough firebug i found this,
XML Parsing Error: no element found Location: moz-nullprincipal:{08ba4230-2feb-48d3-969e-b53579b07b52} Line Number 1, Column 1:
^
还有功能parseXml似乎没有被调用...
also function parseXml doesn't seem to get called...
推荐答案
您无法使用AJAX访问远程域.请参见相同来源政策.您正在尝试访问位于google.com上的脚本，因此，除非此页面位于同一域中，否则它将无法正常工作.进行此工作的唯一方法是在服务器上设置代理服务器脚本，您将向该服务器发送AJAX调用，并将该调用委托给google.com.另一种选择是使用 JSONP ，但是遥远的脚本需要支持它.
You cannot access distant domains using AJAX. See Same Origin Policy. You are trying to access a script located on google.com, so unless this is page is on hosted on this same domain it won't work. The only way to make this work is to setup a proxy server script on your server to which you will send the AJAX call and it will delegate the call to google.com. Another alternative is to use JSONP but the distant script needs to support it.
