AJAX

Instead of saying I was going to look into AJAX, I actually am. Here's a link for further inspection. I'm reading some of it now and it seems pretty basic. Here's an example of the code. Remember, this is basic stuff just for me to get the jist of it.

I know it's a bit messy because the page isn't wide enough, but you can see where it's going nonetheless. Plus, in FeedDemon it looks perfect, which is where I'll be viewing it.

<script type="text/javascript" language="javascript">

var http_request = false;

function makeRequest(url) {

http_request = false;

if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
// See note below about this line
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}

if (!http_request) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = alertContents;
http_request.open('GET', url, true);
http_request.send(null);

}

function alertContents() {

if (http_request.readyState == 4) {
if (http_request.status == 200) {
alert(http_request.responseText);
} else {
alert('There was a problem with the request.');
}
}

}
</script>
<span
style="cursor: pointer; text-decoration: underline"
onclick="makeRequest('test.html')">
Make a request
</span>
