弹出层样式：

.showoutbox{width:300px; min-height:32px; position:absolute; top:0; z-index:300; background:#0F0; display:none; text-align:center; line-height:32px;color:#fff}

.underbox{width:100%; background:#000; filter: alpha(opacity=0);-moz-opacity: 0;opacity: 0; z-index:299; position:absolute; left:0; top:0; display:none;}

弹出层方法：

//弹出层方法

	    function showout(status,datatext){

		    $(".showoutbox").html(datatext);

		    var myleft=($(window).width()-300)/2+'px';		

		    if(status==1)

			    $(".showoutbox").css({left:myleft,display:'block',background:'#529E45'});

		    else if(status==0)

			    $(".showoutbox").css({left:myleft,display:'block',background:'#ED973A'});

		    $(".underbox").css({height:$(window).height()+'px',display:'block'});

	    }

	    //关闭弹出层

	    function hiddenoutbox(){

	        $(".showoutbox").text("");

		    $(".showoutbox").removeAttr("style");

		    $(".underbox").removeAttr("style");

	    }



//status=0或1，代表失败或成功，datatext=提示的文本

层：

<div class="showoutbox"></div>

<div class="underbox"></div>



//不能放到任何div下，直接放到body下
