get乱码

有中文参数的get请求容易乱码，固要给参数加密

var url =“http://localhost:8080/admin/list.htm?zm=哈哈”;
var urls = url.split("=");
// alert("urls[0]=="+urls[0]);
// alert("urls[1]=="+urls[1]);
// url = urls[0]+"="+encodeURI(encodeURI(urls[1]));
url = urls[0]+"="+encodeURI(urls[1]);

后台解密

String xx = new String(request.getParameter("zm").getBytes("ISO-8859-1"), "UTF-8");
