How to listen for Ctrl-P key press in JavaScript?

问题

I want to disable print for some webpages. How to wireup cross browser hotkeys (Cntrl + P) to a javascript that will be fired whenever hotkeys are pressed?

回答1:

You can override by capturing the event.

jQuery(document).bind("keyup keydown", function(e){
    if(e.ctrlKey && e.keyCode == 80){
        return false;
    }
});
