jquery当中bind和unbind，pageX，pageY，.screenX， screenY是怎么用的？

例 2.2（e.pageXscreenX.html）



<script language="javascript" src="jquery.min.js"></script>
<script language="javascript">
$(function(){undefined
/*马克-to-win：和原来一样，pageX指窗口里，screenX指屏幕，所以多了一个上面的菜单。*/
    $("body").bind("click", fn1 = function(e){   
        var posPage = "(" + e.pageX + "," + e.pageY + ")";
        var posScreen = "(" + e.screenX + "," + e.screenY + ")";
        $("span").html("
Page: " + posPage + "
Screen: " + posScreen);
    });
    $("input[type=button]").click(function(){undefined
        $("body").unbind("click",fn1);    //移除事件监听myFunc1
    });
});
</script>
