如何使用一个提交按钮保存多个表单数据 [英] How to save multiple form data using one submit button

问题描述

在我的jsp页面中，我有两种形式.一种形式是进入save_product servlet，另一种形式是进入save_images servlet.只有一个提交按钮.首先单击提交按钮时，我要保存产品，然后再保存图像.

In my jsp page I have two forms.one form action goes to save_product servlet and other one is goes to save_images servlet. There is only one submit button. when click submit button first I want to save products and then want to save images.

我使用jQuery和Request.getRequestDispatcher(String).forward()进行了尝试.但未成功.

I tried it using jQuery and Request.getRequestDispatcher(String).forward() .but it is not succeeded.

这是我的jsp:

    <button type="submit" class="btn btn-default" id="formsave1">Save</button>

    <div class=container>
     <div class="panel">
        <form action="../save_product" method="POST"><button type="submit" id="formsave2" ></button> 
    </div>
      <div class="panel">
        <form action="../save_images" method="POST" enctype="multipart/form-data">
             <button type="submit" id="formsave3"></button>
</div>
    </div>

产品保存servlet:

Product save servlet:

req.getRequestDispatcher("save_images").forward(req, resp);

jQuery:

  $(document).ready(function () {
                $(formsave1).on("click", function (e) {
                    alert('CLICKED 1');
                    $('#formsave2').click();
                       alert('CLICKED 2');
                });

推荐答案

您的代码不足以完全识别问题.我无法发现问题.

Your code is insufficient to identify the problem completely. I cannot spot the issue.

但是，根据您的html代码，我猜这两个servlet都在同一个包中.在这种情况下，您可以直接调用save_images的doPost()或doGet()方法，因为它们都具有protected访问修饰符.

However, as per your html code I guess that both servlets are in the same package. In that case you may directly call the doPost() or doGet() methods of save_images as they both have protected access modifier.

根本不需要使用Requestdispatcher.

There's no need to use the Requestdispatcher after all.

new save_images().doPost(req, resp);
