User Input Redirect (html) to New Page

[steverf]

Hello All,
I am looking for a reliable cross browser method to have a user input a string (order number) and be redirected to a new page based on their input. I need to gracefully fail if the page does not exist. I have tried various methods that did not work reliably and just found this forum... Sure would appreciate any assistance. Many Thanks..SteveRF

Assuming javascript is enabled and the files are in the same domain:


function getFile(fileName){
oxmlhttp = null;
try{
oxmlhttp = new XMLHttpRequest();
oxmlhttp.overrideMimeType("text/xml");
}
catch(e){
try{
oxmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e){
return null;
}
}
if(!oxmlhttp) return null;
try{
oxmlhttp.open("GET",fileName,false);
oxmlhttp.send(null);
}
catch(e){
return null;
}
return oxmlhttp.responseText;
}
function xferCheck(fileNm) {
fileNm+=".htm";
if (getFile(fileNm+".htm") != null)
document.location.href=fileNm;
else
alert ("Requested file "+fileNm+" is not available");
}
...
<input type="text" id="fNum" />
<button onclick="xferCheck(document.getElementById('fNum').value)";
