asked on

webpage code help needed

I have this code that adds a textbox and submit button on my webpage, it takes whatever you enter into the textbox and goes to a address in this case http://jy*******/yur*****/intranet/ adds your text (let's say AML1) and adds .pdf to the end.

Here is what it would look like in case you didn't follow me

http://jy*******/yur*****/intranet/AML1.pdf

My problem is that if the file dosen't exist on the server you get the standard 404 error, now I know that I could change the 404 error and make it custom however I wanted to know if there was a way to check if that file exists and if not redirect them to a different page.

Here is the code:

<html lang="en">
<head>
<base target="main">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="language" content="english">
<meta http-equiv="Content-Style-Type" content="text/css">
<meta http-equiv="Content-Script-Type" content="text/javascript">

<title></title>

<style type="text/css">
#wrapper {
    width:482px;
    margin:auto;
 }
.container {
    float:left;
    width:195px;
    border:0px double #;
    padding:10px 10px 0;
    font-family:sans-serif;
    color:#3333cc;
    text-align:center;
    background-color:#cf8030;
    margin:0 10px;
 }
.container h1 {
    margin:0 0 10px 0;
    font-size:1em;
 }
.container input {
    margin-bottom:10px;
 }
</style>

<script type="text/javascript">

function init() {

   var kywd=['','KEYWORD/'];
   var df=[];
   f=document.getElementsByTagName('form');
for(c=0;c<f.length;c++) {
   df[c]=document.forms[c];
   df[c].number=c;
   df[c].onsubmit=function() {  
   location.href='http://jy*********/yur*****/intranet/'+kywd[this.number]+df[this.number][0].value+".pdf";
   return false;
   }
  }
 }
   window.addEventListener?
   window.addEventListener('load',init,false):
   window.attachEvent('onload',init);

</script>

</head>
<body>

<div id="wrapper">

<form action="#">
<div class="container">
<h1>Enter Password</h1>
<input type="password">
<input type="submit" value="Submit"/>
</div>
</form>


</div>

</body>
</html>

You can also catch this in the .htaccess file - and redirect it to another location if it does not exist.
