How to detect command key is pressed in javascript at mac os

Question

I am working with ctrl+c and ctrl+v event in javascript i want to bind a function on ctrl+v event. and i am able to do it with event.keyCode in windows system but in mac os on command press i am not able to figure out the event. My code is

 $('.hindi_content').keyup(function(event){

        console.log('UP'+event.keyCode);

       console.log('in window::'+ event.ctrlKey+'in mac os'+event.metaKey+'####'+event.META_MASK+'##$&&'+event.CTRL_MASK);

      //  this is  working with windows not with mac os. 
       if(event.keyCode==86 && event.ctrlKey)
        {
            console.log('ctrl press'+event.ctrlKey);

            col_val = $('#'+this.id).val();
            console.log('col val'+col_val);

            $('#hidden_'+this.id).val(col_val);
            console.log('hidden val'+ $('#hidden_'+this.id).val());
            //converter_new(event,this.lang);
            // return;
        } 

});

i search and found event.metaKey but it is for ctrl key in mac i just want command key in mac os.

Answer 1

Things seem to have gotten easier since this question was first asked. I found this answer which states that event.metaKey will work for cmd on mac. I just tested it and it works fine.

document.body.addEventListener("keydown", function(event) {
   var key = event.key;
   var cmd_held = event.metaKey;

   if(cmd_held && key.toLowerCase() == "v") 
       pasta();

});

mousetrap is a library that makes those things really easy:

http://craig.is/killing/mice

//control + v
Mousetrap.bind('ctrl+v', function(e) {
    //do things here
});

//command + k & control +v
Mousetrap.bind(['command+v', 'ctrl+v'], function(e) {
    //do things here
});
