I have a temporary xml file is saved in a directory. I would like to delete this temp file after it's read. But it is not deleting from my code. What am I doing wrong? Thanks.

<SCRIPT language="javascript">
function removeTempFile()
{
String fileName = "C:\\Temp\\temp.xml";
File f = new File(fileName);
if(f.exists())
{
f.delete()
}
else{
alert("no file exists.");
}

}
</SCRIPT>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>

<script type="text/javascript">
var xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.load("temp.xml");
var xsl = new ActiveXObject("Microsoft.XMLDOM");
xsl.async = false;
xsl.load("<%=Stylesheet%>");
document.write(xml.transformNode(xsl));
document.write(removeTempFile());
</script>
</body>
</html>

Use f.remove(), not f.delete().

It is not even calling the removeTempFile() function. I tried deleting the last line and write:
<body onbeforeunload="removeTempFile()"> instead. It didn't get in to the function because it is not printing my message box

You can't write a function like...

document.write(removeTempFile());

You simply call it.

removeTempFile();

also tried your suggestion on my JSP page, but the function didn't get call.

Now I changed my code to:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>


<script type="text/javascript">
function removeTempFile()
{
alert("test");

var strFileName = "C:\\temp\\temp.xml";
alert("strFileName: " + strFileName);

var fso = new ActiveXObject("Scripting.FileSystemObject");
fso.DeleteFile("strFileName",true);

alert("file deleted.");
}
</script>
</head>

<body onbeforeunload="removeTempFile()">
<script type="text/javascript">
var xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.load("temp.xml");
var xsl = new ActiveXObject("Microsoft.XMLDOM");
xsl.async = false;
xsl.load("<%=Stylesheet%>");
document.write(xml.transformNode(xsl));
removeTempFile();
</script>
</body>
</html>

"test" and "strFileName" got printed, but not the last alert box (file deleted). What's wrong with these two lines?
var fso = new ActiveXObject("Scripting.FileSystemObject");
fso.DeleteFile("strFileName",true);

Thank you.

Please start using [code] tags. Thanks!

Are you 100% sure that the file is really there? Test it by creating a blank text file on the C: drive and then use JavaScript to delete it.

Yes, the file is exists in the right location. The code is not getting down to the var fso line, it is not printing my alert box.


var fso = new ActiveXObject("Scripting.FileSystemObject");
alert ("test");

There are only 2 reasons why that line will not work.


You are not using Internet Explorer
Internet Explorer's security setting are blocking it

I'm not allow to change the IE security settings.
How can I use Java's delete function instead of Javascript then?

You could also try VBScript. Either way, since you are working with the client-side, the browser will require user interaction to obtain security allowance.
