Get the iframe's location's page title from a no-locally page?

[bladefinor]

How to do that?

I know that I can get a local page title from an iframe by using this code:

iframe.document.title

But if I want to get an already published page's (like Google) title, how to do that?

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!

Illegal in javascript. In PHP (and other server side languages, if available), this (the availability of importing data from another domain) is controlled by your host's settings.
