The issue of mask layer scroll bars is common

The problem I encountered today is that the mask layer behind the pop-up layer has a scroll bar, so there is no mask layer in the invisible area under the scroll bar. The solution is to add css.

js code

 <script type="text/javascript"> //Show gray JS mask layer function showBg(ct,content){ var bH=$(document).height(); var bW=$("body").width()+16; var objWH=getObjWh(ct); $("#fullbg").css({width:bW,height:bH,display:"block"}); var tbT=objWH.split("|")[0]+"px"; var tbL=objWH.split("|")[1]+"px"; $("#dialog").show();$("#"+ct).css({top:tbT,left:tbL,display:"block"}); $(window).scroll(function(){resetBg()}); $(window).resize(function(){resetBg()}); } function getObjWh(obj){ var st=document.documentElement.scrollTop;//Distance of the scroll bar to the top var sl=document.documentElement.scrollLeft;//Distance of the scroll bar to the left var ch=document.documentElement.clientHeight;//The height of the screen var cw=document.documentElement.clientWidth;//The width of the screen var objH=$("#"+obj).height();//The height of the floating object var objW=$("#"+obj).width();//The width of the floating object var objT=Number(st)+(Number(ch)-Number(objH))/2; var objL=Number(sl)+(Number(cw)-Number(objW))/2; return objT+"|"+objL; } function resetBg(){ var fullbg=$("#fullbg").css("display"); if(fullbg=="block"){ var bH2=$("body").height(); var bW2=$("body").width()+16; $("#fullbg").css({width:bW2,height:bH2}); var objV=getObjWh("dialog"); var tbT=objV.split("|")[0]+"px"; var tbL=objV.split("|")[1]+"px"; $("#dialog").css({top:tbT,left:tbL}); } } //Close the gray JS mask layer and operation window function closeBg(){ $("#fullbg").css("display","none"); $("#dialog").css("display","none");} </script>

css code

 #fullbg{ background-color: Gray; display:none; z-index:3; left:0px; opacity:0.5; top:0; left:0; height:100%; width:100%; z-index:999; position:fixed; _position:absolute; _left: expression_r(documentElement.scrollLeft + documentElement.clientWidth - this.offsetWidth); _top: expression_r(documentElement.scrollTop + documentElement.clientHeight - this.offsetHeight);filter:Alpha(Opacity=30); opacity: 0.3; } #dialog { width:560px; background:#eee; display: none; z-index: 5; padding:16px;font-size:12px;z-index:1000; position:absolute;}#dialog sup{ color:#f00;}#dialog .close0{ position:relative; top:-24px; left:544px; height:38px; width:40px;}

html code

 <div id="fullbg"></div> <!-- end JS mask layer--> <!-- Dialog--> <div id="dialog"><div><a href="#" onclick="closeBg();"><img src="__IMG__/close.png" /></a></div> <div id="dialog_content"><h3>Personal Information</h3><p>(Note: The following information is only used to send you relevant service materials as needed, and will not leak information.
