首先在 tomcat的 D:\apache-tomcat-7.0.57\conf\server.xml里添加中文编码
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
URIEncoding="UTF-8"/>
前台处理
element.value=encodeURI(value,"utf-8");
后台处理
try {
URLDecoder.decode(value,"utf-8");
} catch (Exception e) {
e.printStackTrace();
}
