<p align="center"><font size="5" color="#FF0000">SEARCH</font><br><br>

<font size="3">Enter Name To Search For</font>
<p align="center"><input type="text" id="page" />
<input type="submit" value="submit" onclick="goToPage();" /></a></p><br><br><br><br><br>
</p>

</html>

<script type="">
function goToPage() {
var page = document.getElementById('page').value;
window.location = "http://192.168.0.101/" + page + ".htm";
}
</script>

i have that above and it does most of what i want, but what do i need to add to make it remove the spaces from the name and then check to see if the link exists or not?
