弄了一上午，火狐按键弹起获取鼠标坐标不正确！！（按键shift+@）

function getMousePoint(event) {
var px, py;
if(document.all) { // is ie
px = event.clientX;
py = event.clientY;
px += document.documentElement.scrollLeft;
py += document.documentElement.scrollTop;
} else {
px = event.pageX;
py = event.pageY;
}
return { x: px, y: py };
}

$(document).ready(function() {
 $("input[id*=mail]").click(function(ev){
  ev = ev || window.event;
  if(ev.shiftKey && ev.keyCode==50)
  {
   var mousePos = getMousePoint(ev);
   alert(mousePos.x);
  }
 });

});

 

 

 

 

function getMousePoint(event) {
var px, py;
if(document.all) { // is ie
px = event.clientX;
py = event.clientY;
px += document.documentElement.scrollLeft;
py += document.documentElement.scrollTop;
} else {
px = event.pageX;
py = event.pageY;
}
return { x: px, y: py };
}

$(document).ready(function() {
    $("<div style=\"position:absolute; background:#ccc; display:none;\" id=\"i_mail\"><div class=\"163mail\">163.com</div><div>163.com</div><div>163.com</div><div>163.com</div><div>163.com</div><div>163.com</div><div>163.com</div><div>163.com</div></div>").appendTo("body");
    $("input[id*=mail]").click(function(ev){
        ev = ev || window.event;
        var mousePos = getMousePoint(ev);
        var ithis=$(this);
        ipx=mousePos.x;
        ipy=mousePos.y;
        iheight=ithis.height();
        ipy+=iheight;
        ithis.keyup(function(ev){
            if(ev.shiftKey && ev.keyCode==50)
            {
                $("#i_mail").css({top:ipy, left:ipx, display:""});
            }

            $(".163mail").click(function(){
                    $("#i_mail").hide("slow")
                    var ftext=$(".163mail").text();
                    var ival=ithis.val();
                    ithis.val(ival+=ftext);
            })

        });

    });

});//  不成功！！！！！！！！！！！
