JSP 中js传递和解析URL参数以及中文转码和解码

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：复制代码<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>
