ext 、ajax和servlet结合的一个小例子

extjs:

Ext.onReady(function(){ Ext.get("btnSubmit").on('click',function(){var content =Ext.get("com_content").getValue();if(content==""){ Ext.MessageBox.alert("内容不能为空！"); }else{ Ext.Ajax.request({ url:'MessageBoxServlet', params: {content :content} , Method:"post", success: function(response){//var message = request.responseText; var message = response.responseText; Ext.get("CommentList").dom.innerHTML=response.responseText;//Ext.MessageBox.alert("信息",message); }, failure: function(response){ Ext.MessageBox.alert("错误！"+response.status); } }); } }) })

servlet:

public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { response.setCharacterEncoding("utf-8"); String content = request.getParameter("content");//response.getWriter().write(content); PrintWriter out = response.getWriter(); out.print(content); out.flush(); out.close(); }
