如何在JSP頁面提交表單時不重新加載？這裏是用戶發送消息和AJAX腳本（它在我的jsp中）爲用戶取回所有消息。但是，當我發送消息（做POST方法）刷新我的頁面，需要一些時間來加載所有消息與AJAX。幫助請幫助！這是我的JSP頁面沒有刷新頁面的POST方法。 Spring MVC。 JAVA。 JSP

這是我的控制器

@RequestMapping(value = "/user/messages/{iddialog}", method = RequestMethod.POST) 
    public String messages(@ModelAttribute("message") Message message, @RequestParam(value = "text") String text, 
      @PathVariable(value = "iddialog") int iddialog, Model model, Principal principal) { 
     if(checkingMessage(text)!=true) 
     { 
     sendMessage(iddialog, text, principal.getName()); 

     System.out.println("message sent!"); 
      return "messagesWithUser"; 
     } 
     else 
     { 
      return "redirect:/user/messages"; 
     } 
    }

它的發生，因爲一個提交按鈕的默認操作是發送請求作爲一個正常的請求（不阿賈克斯）。

你必須改變你的形式：

<form onsubmit="return false;" class="navbar-form navbar-right" action="${logoutUrl}" 
        method="post"> 
        <button onclick="function_ajax_to_send_form()" class="btn btn-default" type="submit"> 
         <spring:message code="label.logoutbutton" /> 
        </button> 
        <input type="hidden" name="${_csrf.parameterName}" 
         value="${_csrf.token}" /> 
       </form>

這取決於你的Spring版本。如果你正在使用Spring 3，JQuery的，你可以做些事情是這樣的：

JSP

<%@ page language="java" contentType="text/html; charset=UTF-8" 
    pageEncoding="UTF-8"%> 
<!doctype html> 
<html lang="es" > 
<head></head> 
<body>  
    Your Name: <input type='text' id='name'> 
    <button id='send-button'>Send</button> 
    <div id='state-bar'></div> 

    <script> 
    window.onload=function() { 
       var stateBar=$("#state-bar"); 
       var name=$("#name"); 
       var sendButton=$("#send-button"); 

       sendButton.click(function(event) { 
        var parameters={ 
         name: name.val() 
        }; 

        $.ajax({ 
         type: 'POST', 
         contentType: "application/json; charset=utf-8", 
         data: JSON.stringify(parameters), 
         dataType: "json", 
         url: "myPage.htm", 
         success: function (data) { 
          stateBar.html(data.response); 
         }, error: function(data){ 
          stateBar.html("Server Error."); 
         } 
        }); 
       }); 
    } 
    </script> 
    <script src="resources/js/jquery.js"></script> 
</body>

控制器類

package com.company.controllers; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestBody; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.ResponseBody; 

@Controller 
public class TestController { 

    @RequestMapping(value="/testPage.htm",method=RequestMethod.GET) 
    public String testPage(){ 
     return "testPage"; 
    } 

    @RequestMapping(value="/myPage.htm",method=RequestMethod.POST) 
    @ResponseBody 
    public MyPageResponse myPage(@RequestBody MyPageModel myPageModel){ 
     MyPageResponse res= new MyPageResponse(); 
     res.setResponse("Your name is : "+myPageModel.getName()); 
     return res; 
    } 

}

輸入VO

package com.company.controllers; 

public class MyPageModel { 
    private String name=""; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

}

輸出VO

package com.company.controllers; 

public class MyPageResponse { 
    private String response=""; 

    public String getResponse() { 
     return response; 
    } 

    public void setResponse(String response) { 
     this.response = response; 
    } 
}

    <servlet-mapping>

感謝名單的答案，但它並沒有幫助！ –

你試過這個例子嗎？日誌文件中是否有錯誤？可能需要一些庫。 – Rubens
