Javascript check ctrl+s

Question

I'm new to js. How can I check if the client press the key combination ctl + s ?

$(document).keypress(function(e) {
  if(e.charCode == 17 && e.charCode == 83) {
    alert("ok");
  }
});

This doesn't work. Jquery is included.

This would work if you are jQuery.

 $(document).ready(function() { $(document).keydown(function(event) { if (event.ctrlKey && event.keyCode == 83) { event.preventDefault() //action here alert('Saved'); } }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> Press ctrl +s 

Working fiddle here .

If you want to detect cmd + s on mac, you need to use keycodes mentioned below on different-different browsers, beacuse unlike Shift/Alt/Ctrl, Mac/Apple key is not considered as a modifier key--instead, you should hook on keydown/keyup and record when a key is pressed:

Firefox: 224
Opera: 17
WebKit (Safari/Chrome): 91 (Left Apple) or 93 (Right Apple)

I got from here .

And if you want close your browser tab on save window.top.close(); will work that I got from here . Also working for me.
