decode函数吗 jsp_JSP中js传递和解析URL参数以及中文转码和解码问题
1.傳遞參數:
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
//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
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:
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;
}
這樣調用:
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'];
