HTML页面如何象asp一样接受参数

<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>
