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>
