使用 javascript 替换浏览器 ctr + n 默认处理程序？

Question

I was wondering whether a tricky JavaScript snippet exists, to replace web browsers default Crl+N event handler(they open a new file). (I know it's a bad boy's job and I also know chances are low.)

Answer 1

Browsers are designed so that websites run in sandboxes. Preventing anything that goes sour ( maliciousness intended or not ) to not affect the computer itself. So you might be able to change your own browser settings, I doubt you will find an easy way to do this.

In addition you shouldn't do this even if you find a way. IE will let you erase the clipboard, but that doesn't mean doing so wont piss off every user who visits your website.

Why do you want such behavior anyway? I cannot see any amicable reason.

Answer 2

Nope, I just tried it. It doesn't work:

$(window).keydown(function(e){
  if(e.which == 17)
      $(window).bind('keydown.ctrln', function(e){
          if(e.which == 78){
              e.preventDefault();
              alert('CTRL+N');
          }
      });
});

$(window).keyup(function(e){
  if(e.which == 17)
      $(window).unbind('keydown.ctrln');
});

Changing e.which == 78 to e.which == 73 makes it work in Chrome if you press Ctrl+i since Ctrl+i doesn't have any default action in Chrome. But you can't overwrite the default browser behavior, which is what I was guessing was going to happen anyways.
