How can I pass a click through an element?

I want to display an image under the mouse (a finger to simulate a touch screen) when a mousedown event occurs and hide it when the mouseup event occurs, but when I do this, the image I display blocks the subsequent mouse events ("click" in particular) on elements under this image. I'm using jQuery, by the way.

I'm sure this is something to do with event bubbling or propagating or somewhat, but I couldn't f开发者_如何学Pythonigure it out. Any pointers please?

It seems to do what I understand what you want to achieve using a pure cross browser CSS approach.

pointer-events:none; touch-action:none;

Billy Moon, your code was almost working. You just have to use hide and show instead of css :

$('#finger').click(function(e){
  evt = e || window.event;

  // make finger disappear
  $('#finger').hide(0);

  // get element at point of click
  starter = document.elementFromPoint(evt.clientX, evt.clientY);

  // send click to element at finger point
  $(starter).click();

  // bring back the finger
  $('#finger').show(0);
});

This is untested - but is based on a working script of mine, so should be along the right lines. Basically, you have to make the layer that is in the way disappear for a moment, so you can use the elementFromPoint method and then make it come back.

$('.selector').click(function(e){
    evt = e || window.event;

    // make finger disappear
    $('.finger').css({display:'none'});

    // get element at point of click
    starter = document.elementFromPoint(evt.clientX, evt.clientY);

    // send click to element at finger point
    $(starter).click();

    // bring back the finger
    $('.finger').css({display:''});
});

You can do this

$(document).bind('mousedown mouseup', function() {
    $('.finger').toggle();
});
