Hello all,
I'm looking for a way to check if a link exists on a certain page. I know that this is possible with a ping, but I really don't know how to do this.
What I have is a list of links to other webpages, they should have a backlink to my page also. I want to check this, when the backlink is there, a text should appear, something like "ok" and when the result is negative, something like "no backlink"
I know the urls of the pages where my link should appear, in case you need to know that.
Any help would be great!
I have found a piece of code wich I think could be used to serve my needs. I self don't know how, but it would be great if anyone can help me with this.
This is the code:
<html>
<head>
<script language="javascript" type="text/javascript">
<!--
var ajax = new XMLHttpRequest();
function pingSite() {
ajax.onreadystatechange = stateChanged;
ajax.open('GET', document.getElementById('siteToCheck').value, true);
ajax.send(null);
}
function stateChanged() {
if (ajax.readyState == 4) {
if (ajax.status == 200) {
document.getElementById('statusLabel').innerHTML = "Success!";
}
else {
document.getElementById('statusLabel').innerHTML = "Failure!";
}
}
}
-->
</script>
</head>
<body>
Site To Check:<br />
<input type="text" id="siteToCheck" /><input type="button" onclick="javascript:pingSite()" />
<p>
<span id="statusLabel"></span>
</p>
</body>
