如何对两个HTML表单使用相同的submit

Question

我想问一下我如何才能在一个页面中使用相同的提交2个html表单。我希望对这两个表单都有相同的操作，从而使用相同的servlet来处理Reuqest。

   <form action = "add">
     Enter first number: <input type = "text" name = "num1"><br>
     Enter second number: <input type = "text" name ="num2"><br>
  </form>
  <br>
  <br>
   <form action = "add">
     Enter Third: <input type = "text" name = "num1"><br>
     Enter fourth: <input type = "text" name ="num2"><br>
     <input type = "submit"> 
  </form>
</body>

1您可以输入一个隐藏参数，如

<input type="hidden" name="fieldHidden" value="formOne/formTwo">

在每个表单的jsp文件中。

在servlet上，您将把参数的值传递到新变量中

String form = request.getParameter("fieldHidden");

if(form.equals("formOne"){ 
  //process create logic for form 1
}
else if(form.equals("formTwo")) {
  //process create logic for form 2
}

例如：在您的jsp文件中：

  <form action = "add">
     <input type="hidden" name="fieldHidden" value="formOne">
     Enter first number: <input type = "text" name = "num1"><br>
     Enter second number: <input type = "text" name ="num2"><br>
     <input type = "submit"> 
  </form>
  <br>
  <br>
  <form action = "add">
     <input type="hidden" name="fieldHidden" value="formTwo">
     Enter Third: <input type = "text" name = "num1"><br>
     Enter fourth: <input type = "text" name ="num2"><br>
     <input type = "submit"> 
  </form>

在servlet上，您将把参数的值传递到新变量中

String form = request.getParameter("fieldHidden");

if(form.equals("formOne"){ 
  //process create logic for form 1
}
else if(form.equals("formTwo")) {
  //process create logic for form 2
}
