Javascript: Escape key = browser back button

In a browser how can I make the keyboard's escape key go back in Javascript.

For example: if you visit this page and click the "Fullscreen" link I'd like to press the 开发者_JAVA技巧escape key and go back to the previous page.

What's the Javascript to make this magic happen?

You can add a Key-Listener:

window.addEventListener("keyup", function(e){ if(e.keyCode == 27) history.back(); }, false);

This will call history.back() if the Escape key (keycode 27) is pressed.

$(document).bind("keyup", null, function(event) {
        if (event.keyCode == 27) {  //handle escape key
            //method to go back            }
    });

You can bind an onkeyup event handler to window and check if the keycode is 27 (keycode for Escape), then use the window.history.back() function.

window.onkeyup = function(e) {
  if (e.keyCode == 27) window.history.back();
}

Just listen for key code 27 and call history.go(-1);

You need to listen for the 'ESC' keypress, and fire off the back action when it is pressed, like so:

document.onkeydown = function(e){ 
   if (window.event.keyCode == 27) {
      history.go(-1);
   }
};
