就是当点击 发送 的时候把这个对话框内容添加上去,然后由Servlet接收对话框内容参数 并调Service把取得 自动回复 的内容再添加到对话框去。
至于具体的Service实现暂时不关心。
1、首先打开JSP页面找到发送对应的button,添加事件,取名为 send()
2、下一步就是实现这个 send() 方法,这需要用到 AJAX 参考 -->
参考上面的就可以轻易看懂下面的代码了
function send() { var content = $("#content").val(); if(!content) { alert("请输入内容!"); return; } $.ajax({ url : $("#basePath").val() + "AutoReplyServlet.action", type : "POST", dataType : "text", timeout : 10000, success : function (data) { appendDialog("talk_recordboxme","My账号",content); appendDialog("talk_recordbox","公众号",data); $("#content").val(""); render(); }, data : {"content":content} }); }
很典型的 $("#content").val() 既充当了 getter 也充当了 setter
完整的代码贴在底部 -->
3、把这个 .js 文件包含进JSP页面
<script type="text/javascript" src="<%= basePath %>resources/js/front/talk.js"></script>
4、随便写个 Servlet 测试一下
package com.imooc.servlet; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; // import com.imooc.service.QueryService; /** * 自动回复功能控制层, * 针对AJAX的 */ @SuppressWarnings("serial") public class AutoReplyServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { resp.setContentType("text/html;charset=utf-8"); PrintWriter out = resp.getWriter(); out.write("我听不懂你在说啥"); // 本来这里是需要调Service的 out.close(); } @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { this.doGet(req, resp); } }
完善 Service 之后就大功告成了。。。
JSP页面
