get传参乱码问题 (js to java)

前台js代码块中对各个变量进行编码处理如下:

var typeselect = form2.typeselect.value;

//var typeselect = document.getElementById('typeselect').value;

//怎么获得值得自己用自己的方式, 不一定要像我酱紫..

typeselect=encodeURI(typeselect);

typeselect=encodeURI(typeselect);

form2.action="xxxx.do?typeselect="+typeselect;

form2.submit();

在后台进行获取:

import java.net.URLDecoder;

if (request.getParameter("typeselect") != null) {

typeid = request.getParameter("typeselect");

typeid = URLDecoder.decode(typeid, "utf-8");

}
