利用javascript对象弹出一个层-丞旭猿

实现代码如下：

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=gb2312″ />
<title>-弹出一个层</title>
<script language=”javascript”>
function cmsgbox(vtitle,vwidth,vhight,vtop,vleft)
{
this.title=vtitle;
this.width=vwidth;
this.height=vhight;
this.top=vtop;
this.left=vleft;
this.id=0;
}
cmsgbox.prototype.showdiv=function()
{
var str=””;
str+=”<div id=’div1′ style=’z-index:1;background-color:white;position:absolute;border:2px solid slategray;left:”+this.vleft+”px;top:”+this.vtop+”px;width:”+this.width+”px;’>”;

str+=”<div style=’padding-bottom:2px;background-color:slategray;width:100%;height:16px;color:white;’ >”;
str+=” <div style=’float:left;height:16px;overflow:hidden;margin:0px;padding:4px 0px 0px 5px;width:”+(parseInt(this.width)-24*2-5)+”px;’>”+this.title+”</div>”;
str+=” <span style=’width:14px;font-family:webdings;cursor:hand;’>0</span>”;
str+=” <span style=’width:14px;font-family:webdings;cursor:hand;’ onclick=’cmsgbox.closediv(this);’>r</span>”;
str+=”</div>”;

str+=”<div style=’ margin:10px 5px 10px 10px;word-break:break-all;’>”;
str+=”xxx”;
str+=”</div>”;
str+=”</div>”;
//document.write(str);
document.body.insertAdjacentHTML(“beforeEnd”,str);
}
/////////////////////窗口显示//////////////////////////////
function show()
{
var box=new cmsgbox(‘小家伙呀’,400,300);
box.showdiv();
}
</script>
</head>
