JavaScript or jQuery event handlers for “Ctrl”/“Shift” + mouse left button click

Question

Is it possible to handle such events as:

• Ctrl + mouse left button click;
• Shift + mouse left button click;
• Alt

Answer 1

More recently I encountered a problem with using e.ctrlKey in that, it does not work on MACs. In a Macintosh, the same effect is achieved using Command+Click.

Since most of the answers above are already assuming usage of jQuery, you can simply use the e.metaKey property which is made available by jQuery.

e.g.

$(selector).click(function(e) {
  if(e.shiftKey) {
    //Shift-Click
  }
  if(e.metaKey) {
    //Ctrl+Click on Windows & Command+Click on Mac.
  }
  if(e.altKey) {
    //Alt+Click
  }
});

If you use JQuery plugin called hotkeys you can handle the special keys below.

$(document).bind('keydown', 'Ctrl+c', fn);

Answer 3

You can do something like this (jQuery for the click handler, but any framework works on the part that matters):

$(selector).click(function(e) {
  if(e.shiftKey) {
    //Shift-Click
  }
  if(e.ctrlKey) {
    //Ctrl+Click
  }
  if(e.altKey) {
    //Alt+Click
  }
});

Just handle whichever you want inside an if inside the click handler like I have above.
