// Many thanks to http://jsbin.com/uhuto/1

// I just arranged their work into a jquery plugin

​

// Plugin

$.fn.passThrough = function (targets) {

    if (this.length) {

        if ('pointerEvents' in this.get(0).style) {

            this.css({'pointer-events': 'none', 'user-select': 'none', 'touch-callout': 'none'});

        } else {

            // Polyfill

            this.bind('click tap mousedown mouseup mouseenter mouseleave', function passThrough (e) {

                $(targets).each(function() {

                    // check if clicked point (taken from event) is inside element

                    var mouseX = e.pageX;

                    var mouseY = e.pageY;

                    var offset = $(this).offset();

                    var width = $(this).width();

                    var height = $(this).height();

                    if (mouseX > offset.left && mouseX < offset.left+width &&

                        mouseY > offset.top && mouseY < offset.top+height) {

                            $(this).trigger(e.type, e);

                    }

                });

            });

        }

    }

    return this;

};

​

// Usage

$("#shield").passThrough(".box");

​

​

​

// Make the Demo Pretty

$(".box").click(function(){

     $(this).toggleClass("highlight");

});

​

var dthen = new Date();

setInterval(function(){

    dNow = new Date();

    $('#shield').css('height', ((dNow.getSeconds()+(dNow.getMilliseconds()/1000))*50)%300 +'px');

},10);
