HTML获取URL参数 IFRAME动态显示

html获取url参数例

<script language="javascript">
var pos,str,para,parastr,tempstr1;
tempstr="";
str = window.location.href;
pos = str.indexOf("?")
parastr = str.substring(pos+1);
document.write("<br>文件路径："+str);
if (pos>0){
document.write("<br>所有参数："+parastr);
}
else
{
document.write ("无参数");
}


if (str.indexOf("&")>0){
para = parastr.split("&");
for(i=0;i<para.length;i++)
{
tempstr1 = para[i];

pos = tempstr1.indexOf("=");
//document.write (tempstr1.substring(0,pos));
document.write ("<br>参数"+i+":"+tempstr1.substring(0,pos));
document.write ("等于:"+tempstr1.substring(pos+1));
}
}
     </script>

===========================================================

JavaScript的location.search属性可以返回当前网页URL中？后面的部分，例如：

当前网页地址：http://bbs.dvbbs.net/dispbbs.asp?boardID=1&ID=1212500&page=2

location.search返回值就是 ?boardID=1&ID=1212500&page=2

iframe动态显示获取url

<script language="javascript">
				var pos,str,para,parastr;
				tempstr="";
				str = window.location.href;
				pos = str.indexOf("?")
				parastr = str.substring(pos+1);
				//将参数打出来window.alert(parastr);
				if (pos>0){
				document.write("<frameset rows='*,15%' cols='*' frameborder='no' border='0' framespacing='0'>");
				document.write("<frameset rows='*' cols='*,105' framespacing='0' frameborder='no' border='0'>");
				document.write("<frame scrolling='no' noresize='noresize'  name='mainFrame' id='mainFrame' title='mainFrame' src='http://www.baidu.com/"+parastr+"'/>");
				document.write("<frame src=www.baidu.com' name='rightFrame' scrolling='no' noresize='noresize' id='rightFrame' title='rightFrame' />");
				document.write("</frameset>");
				document.write("<frame name='topFrame' scrolling='no' noresize='noresize' id='topFrame' title='topFrame' src='www.baidu.com'>");
				document.write("</frameset>");
				}
				else
				{
				//document.write ("无参数");//+parastr+
				}
				
     </script>
