Access Local Files with Local Javascript [duplicate]

Answer 1

According to the Firefox documentation, the following code will work:

var req = new XMLHttpRequest();  
req.open('GET', 'file:///home/user/file.json', false);   
req.send(null);  
if(req.status == 0)  
  dump(req.responseText);

I seem to recall it only works within the same directory as the HTML page. And I don't know if this will work in other browsers.
