从与显示的文本字段不同的文本字段中提交值

I've got a form with a dropdown (%ul.dropdown) and a text field (%input). The dropdown has a list of books. Whenever an item from the dropdown is clicked, the book title will appear in the text field (I do this in a Javascript not included in the code sample). If I submit the form, I want the id from the item to be submitted, not the title itself. I can achieve this by messing around with hidden fields and jQuery, however, it would be better if there was a simple and elegant way to do it. Any thoughts? Thanks

我有一个带有下拉列表(%ul.dropdown)和文本字段(%输入)的表单。下拉列表中有一系列书籍。每当点击下拉列表中的项目时,书名将出现在文本字段中(我在代码示例中未包含的Javascript中执行此操作)。如果我提交表单,我希望提交项目的ID,而不是标题本身。我可以通过搞乱隐藏字段和jQuery来实现这一点,但是,如果有一种简单而优雅的方法可以做到这一点会更好。有什么想法吗?谢谢

Code (in haml):

代码(以haml为单位):

.input-group
  %input.form-control#book-selected{ type: "text", placeholder: "Please, select" }/  
    .input-group-btn
      %button.btn.button-transparent.dropdown-toggle{"data-toggle" => "dropdown", type: "button"}
        .icon-arrow-down
      %ul.dropdown-menu.pull-right#books-list
        - @books.each do |book|
          %li
            %a.book-select{ href: "#", 'data-book-id' => book.id }= book.name

Here are some examples of submit listeners:

以下是提交侦听器的一些示例:

提交表单的事件监听器

Use submit event listener when form is submitted via inline JavaScript?

通过内联JavaScript提交表单时使用提交事件监听器?

这里也提出了类似的问题。

Code example:

$('#myform').submit(function(event) {
  $('#book-selected').val( currentBookId );
  this.submit();
});
