废话少说 直接上代码 代码是程序员交流的最好方式 哈哈:
代码如下:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
My JSP 'index.jsp' starting page -->
function selectChange(obj){
var value=obj.value;
var v1 = document.getElementById("tr1");
var v2 = document.getElementById("tr2");
if(value==0){
console.log("two is hidden");
v1.style.display="none";
v2.style.display="none";
}else if(value==1){
v1.style.display="block";
v2.style.display="none";
}else{
v1.style.display="none";
v2.style.display="block";
//将里面的值设为空
}
}
实现效果如下:
