有關js傳遞和解析URL參數以及中文轉碼和解碼問題，都是在js中很常見的，下面通過示例簡單為大家介紹下，感興趣的朋友可以參考下

1.傳遞參數：

復制代碼代碼如下:

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.接收和解析參數

復制代碼代碼如下:

//獲取URL參數
function GetRequest() {
var url = location.search; //獲取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;//測點
sensor = decodeURI(decodeURI(Request['sensor']));
3.參考內容：
方法一：正則分析法

復制代碼代碼如下:

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;
}
這樣調用：
alert(GetQueryString("參數名1"));
alert(GetQueryString("參數名2"));
alert(GetQueryString("參數名3"));

方法二：

復制代碼代碼如下:

<span><Script language="javascript">
function GetRequest() {
var url = location.search; //獲取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>
這樣調用：
<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 參數1,參數2,參數3,參數N;
參數1 = Request['參數1'];
參數2 = Request['參數2'];
參數3 = Request['參數3'];
參數N = Request['參數N'];
</Script>
