The problem here is that if u make use of pure ajax without any supporting server script, it can only work within your domain, if u wish to get info on pages outside your domain, then use php or something. I am good with ajax and php, but not too efficient with asp, so lemme give u a php and an ajax (javascript code) to do that:
getPageTitle.html
<title>Get Page Title</title>
<script>
function ajaxRequest(){
var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"] //activeX versions to check for in IE
if (window.ActiveXObject){ //Test for support for ActiveXObject in IE first (as XMLHttpRequest in IE7 is broken)
for (var i=0; i<activexmodes.length; i++){
try{
return new ActiveXObject(activexmodes[i])
}
catch(e){
//suppress error
}
}
}
else if (window.XMLHttpRequest) // if Mozilla, Safari etc
return new XMLHttpRequest()
else
return false
}
function getTitle(url) {
var mygetrequest=new ajaxRequest()
mygetrequest.onreadystatechange=function(){
if (mygetrequest.readyState==4){
if (mygetrequest.status==200){
var data=mygetrequest.responseText;
// regexp which parses text for value between <title> .. </title> tags
var title2 = new RegExp("<title>[\n\r\s]*(.*)[\n\r\s]*</title>", "gmi");
var title = title2.exec(data);
alert(title);
}
else{
alert("The url '"+url+"' is not accesible.");
}
}
}
var request=url+"?cache="+new Date().getTime();
mygetrequest.open("POST", request, true)
mygetrequest.send(null)
return;
}
//getTitle("http://localhost/");
getTitle("http://www.mwebng.net/");
</script>
getPageTitle.php
<?php
$url="http://www.mwebng.net/";
function getTag($string, $tagname) {$pattern = "/<$tagname>(.*?)<\/$tagname>/";preg_match($pattern, $string, $matches);return $matches[1];}
echo(getTag(file_get_contents("$url"),"title"));
?>
See, it is easier done with php!
