用servlet提交 WangEditor3编辑的内容,找了很多资料没发现,大多用的框架,今天终于解决了,记录一下。
WangEditor3不支持放在textarea中,servlet是无法直接获取到编辑器中的内容的,有一下两种方法:
方法一:如果想用form表单提交需要加个textarea,此时的textarea应该隐藏起来,用js获取WangEditor3编辑的内容,再赋值给textarea,再form提交,隐藏textarea如下:
<textarea name="newscontent" id="content" style="width:100%; height:200px;display:none" ></textarea>
方法二:可以用ajax通过用js取出表单和富文本中的内容,通过json格式传输,在后台获取就可以了。
注明:以下演示以方法二为例,方法一在代码中注释掉了。
newseditor.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%> <%
String path = request.getContextPath();//获取webContent路径
//request.getScheme() 返回当前链接使用的协议;比如,一般应用返回http;SSL返回https;
//详解:https://www.cnblogs.com/qlqwjy/p/7498511.html
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
+ path + "/";

新建Servlet ContentPublish
package com.liu.Controller; import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; /**
* Servlet implementation class ContentPublish
*/
@WebServlet("/contentpublish")
public class ContentPublish extends HttpServlet {
private static final long serialVersionUID = 1L; /**
* @see HttpServlet#HttpServlet()
*/
public ContentPublish() {
super();
// TODO Auto-generated constructor stub
} /**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.getWriter().append("Served at: ").append(request.getContextPath());
} /**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.println("post");
String newsMan=request.getParameter("newsMan");
String newsTitle=request.getParameter("newsTitle");
String introduce=request.getParameter("introduce");
System.out.println(newsMan);
System.out.println(newsTitle);
System.out.println(introduce); } }
效果如下:
控制台输出:
