我有一个简单的脚本,可以捕获所有鼠标单击,除非您单击实际起作用的东西.链接,Flash视频等.在视频加载,新页面加载等之前,无论用户单击什么,如何进行调整？它都会发送我构建的简单GET请求？

(function($) { 

$.fn.saveClicks = function() { 
$(this).bind('mousedown.clickmap',function(evt) {
    var clickDocument = (document.documentElement != undefined && document.documentElement.clientHeight != 0) ? document.documentElement : document.body;
    var width = clickHeatDocument.clientWidth != undefined ? clickDocument.clientWidth : window.innerWidth;
    var height = clickHeatDocument.clientHeight != undefined ? clickDocument.clientHeight : window.innerHeight;
    var scrollx = window.pageXOffset == undefined ? clickDocument.scrollLeft : window.pageXOffset;
    var scrolly = window.pageYOffset == undefined ? clickDocument.scrollTop : window.pageYOffset;
    var x = evt.clientX + scrollx;
    var y = evt.clientY + scrolly;
    $.get('/click-save.PHP',{  
        "x":x,"y":y,"click":"true","w":width,"h":height,"l":escape(document.location.pathname),"d":escape(document.domain)
    }); 
}); 
};

})(jQuery); 

$(function() {
    $(document).saveClicks();
});
