Javascript : Check local file's existence using javascript

var req = new XMLHttpRequest();  
req.open('GET', '20121209.xml', false);   
req.send(null);  
if(req.status == 0)
{ 
//file exist
}

I want to check whether file is existed or not in local machine using javascript. So I wrote the code like above. I can check when file is existed, but I cannot check when the file is not existed.

Finally I want to do something when file is not existed. Can I do this???
