jquery弹出层完美居中

showDiv($("#pop")); function showDiv(obj){     $(obj).show();     center(obj);     $(window).scroll(function(){          center(obj);     });     $(window).resize(function(){         center(obj);     }); }

function center(obj){     var windowWidth = document.documentElement.clientWidth;        var windowHeight = document.documentElement.clientHeight;        var popupHeight = $(obj).height();        var popupWidth = $(obj).width();         $(obj).css({             "position": "absolute",            "top": (windowHeight-popupHeight)/2+$(document).scrollTop(),            "left": (windowWidth-popupWidth)/2        });  }
