如何使用一个提交按钮保存多个表单数据

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');
                });
