How can JS check if a file exists?

Hello, Is there any way to check if a file exists (Like exe's, images, html docs, etc) with Javascript?

No. Javascript is not capable of that. You will have to use a Server Side language such as Perl, PHP, ASP or Java.

Yes, through XMLHTTP object. Something similar to this (http://www.codingforums.com/showthread.php?t=14463), you just need to check if the HTTP status is 404 or not. But server-side solution might be more appropriate for your situation.

Please try the following script:


var fso = new ActiveXObject("Scripting.FileSystemObject");
filename="test.txt";
if (fso.FileExists(filename)){
// file exists
}
