Testing if a file exist

[nkamp]

Hello,

I'm maintaining a application. In this application there a files (like .doc, .txt, .jpg) opened with:

setFrame('frm_file', '/ALGEBESTANDEN/' + file_link);

Where file_link is a variable wich is comming from sql-server database.
But now somebody has deleted the file, while the name is still in the database.
Is there in Javascript a opportunity to test if the file exist like:

if (getFile(file_link) != null)
{
   //the operation
}

Can anybody help me with this.

Thanks in advance.

Greetings,

Nico

If the file is on a server, and is an image file, you could try to load it, harnessing the onerror event of the imange object. If it's not an image (or even if it is), you would be better off doing this detection server-side.

Hope this helps,
Dan
