Javascript Detect Control Key Held on Mouseup

Question

I\'ve searched a good deal, and can\'t seem to find a satisfactory solution. I hope someone can help.

While I am using jQuery, I am also writing many thousands of lines

Answer 1

You can use the event.ctrlKey property.

$(function(){
  $('#elementId').mouseup(function(e){
    var isCtrlPressed = e.ctrlKey;
    // true or false whether ctrl is pressed or not 
  });
});
