function getParam(paramName)
    {
        paramValue = “”;
        isFound = false;
        if (this.location.search.indexOf(“?”) == 0 && this.location.search.indexOf(“=”)>1)
        {
            arrSource = unescape(this.location.search).substring(1,this.location.search.length).split(“&”);
            i = 0;
            while (i < arrSource.length && !isFound)
            {
                if (arrSource[i].indexOf(“=”) > 0)
                {
                     if (arrSource[i].split(“=”)[0].toLowerCase()==paramName.toLowerCase())
                     {
                        paramValue = arrSource[i].split(“=”)[1];
                        isFound = true;
                     }
                }
                i++;
            }   
        }
        return paramValue;
    }

用法:
<span>
<script language=”javascript”>
    document.write(getParam(“name”) + ” ” + getParam(“age”));
</script>
</span>
