Overriding shortcut keys in Firefox and Chrome

rated 0 times [ 77] [ 5] / answers: 1 / hits: 16040 / 11 Years ago, tue, april 9, 2013, 12:00:00

I have a script that is supposed to open a section of a web page, and save changes on Ctrl + n and Ctrl + s respectively. I got it working in IE, but it doesn't seem to work in Firefox and Chrome. Any ideas?

My override function.

function prevent(e)

{

try{e.stopPropagation();}catch(ex){}

try{e.preventDefault()}catch(ex){}

try{if (e.preventDefault)

        e.preventDefault();

    else {

        e.cancelBubble = true;

        e.returnValue = false;

        e.keyCode = 0;

    }}  catch(ex){}

}

I have seen the same issue. Some browsers will not allow you to capture certain shortcuts. Look at this https://stackoverflow.com/a/7296303/1366887

Some key combinations are resticted in Chrome 4, but not in Chrome 3. Look here: https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-bugs/Ntc1byZXHfU

Here is the Javascript:

$(window).keydown(function(event) {

  if(event.ctrlKey && event.keyCode == 84) { 

    console.log(Hey! Ctrl+T event captured!);

    event.preventDefault(); 

  }

  if(event.ctrlKey && event.keyCode == 83) { 

    console.log(Hey! Ctrl+S event captured!);

    event.preventDefault(); 

  }

});

I have used this numerous times, and it has worked greatly.

Here is another rescource you can take a look at: http://unixpapa.com/js/key.html

Without Jquery:

onkeydown = function(e){

  if(e.ctrlKey && e.keyCode == 'S'.charCodeAt(0)){

    e.preventDefault();

    //your saving code

  }

}

Here is a JSFIDDLE of it working.
