I'm trying to create an ajax connection to a weather xml feed and then parse returned data. I don't have any issues making a connection via IE, but for some reason I don't have any luck in FF or Safari. Basically what I'm doing is running an html file that contains the following code.
<html>
<script type="text/javascript" language="javascript">
function makeRequest(zip) {
var url = 'http://rdona.accu-weather.com/widget/rdona/weather-data.asp?location=' + zip;
//var httpRequest;
var httpRequest = false;
if (window.XMLHttpRequest) {
document.write("xmlhttprequest");
httpRequest = new XMLHttpRequest();
if (httpRequest.overrideMimeType) {
httpRequest.overrideMimeType('text/xml');
// See note below about this line
}
}
else if (window.ActiveXObject) { // IE
try {
httpRequest = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {}
}
}
if (!httpRequest) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
httpRequest.onreadystatechange = function() { alertContents(httpRequest); };
httpRequest.open('GET', url, true);
httpRequest.send('');
}
function alertContents(httpRequest) {
if (httpRequest.readyState == 4) {
if (httpRequest.status == 200) {
alert(httpRequest.responseText);
} else {
alert('There was a problem with the request.');
}
}
}
makeRequest(84405);
</script>
</html>
Any help and or suggestions would be greatly appreciated.
