JSP中js传递和解析URL参数以及中文转码和解码问题

1.传递参数：

var pmt = 'sensor='+ encodeuri(encodeuri(sensor))+'&device='+encodeuri(encodeuri(device))+'&instrument=';
pmt += encodeuri(encodeuri(instrument))+'&n='+n+'&adddate='+adddate;
top.location.href = 'jsp/print/diagnosticanaprint.jsp?'+pmt;

2.接收和解析参数

//获取url参数
function getrequest() {
var url = location.search; //获取url中"?"符后的字串
var therequest = new object();
if (url.indexof("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
therequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
return therequest;
}

var sensor;//测点
sensor = decodeuri(decodeuri(request['sensor']));
3.参考内容：
方法一：正则分析法

function getquerystring(name) {
var reg = new regexp("(^|&)" + name + "=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}
这样调用：
alert(getquerystring("参数名1"));
alert(getquerystring("参数名2"));
alert(getquerystring("参数名3"));

方法二：

<span style="font-size: 16px;"><script language="javascript">
function getrequest() {
var url = location.search; //获取url中"?"符后的字串
var therequest = new object();
if (url.indexof("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
therequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
return therequest;
}
</script></span>
这样调用： 
<script language="javascript">
var request = new object();
request = getrequest();
var 参数1,参数2,参数3,参数n;
参数1 = request['参数1'];
参数2 = request['参数2'];
参数3 = request['参数3'];
参数n = request['参数n'];
</script>
