我怎样才能从调用单一形式的多个动作？ [英] How can I invoke multiple actions from a single form?

问题描述

我在，我有一个表单的jsp文件。它显示了大约一个账户数据结构，我们有数据。有一个按钮，从该数据结构删除数据。

I have a jsp file in which I have a form. It shows data about an "account" data structure we have. There's a button to remove the data from that data structure.

<form action="removeThisData.html" method="post">
  ... blah blah blah ...
  <input type="submit" value="Remove"/>
</form>

现在，还有，我想成为一个可编辑的组件。基本上，我想那第三嗒嗒要变成一个日期。这就是我希望我能做到。

Now, there's a component that I want to be editable. Basically, I want that third blah to be turned into a date. Here's what I wish I could do.

<form action="removeThisData.html" method="post">
  ... blah blah blah ...
  <input type="submit" value="Change blah to date"/>
  <input type="submit" value="Remove"/>
</form>

不幸的是，刚刚按钮作用于形式的行动，这将调用映射到removeThisData.html的功能。

Unfortunately, that button just acts upon the form action, which invokes the functionality mapped to "removeThisData.html".

我怎样才能得到相同的形式两种不同的行为？是同一个表单中的多个行为甚至有可能的调用？如果不是，是有办法preserve一个范围内的所有信息，或者我必须重复数据/信息两种不同的形式？

How can I get two different behaviors from the same form? Is the invocation of multiple actions even possible within the same form? If it is not, is there a way to preserve all the information within a single scope or do I have to repeat the data/information in two different forms?

谢谢！

推荐答案

您可以重命名 removeThisData.html ，比方说，manageThisData.html 。您可以检查值的提交对服务器端按钮，并进行适当的行动的基础上，值，这将是一个删除或更改等等最新

You could rename removeThisData.html to, say, "manageThisData.html". You can examine the "value" of the submit button on the server-side and perform suitable action, based on the value, which would be one of "Remove" or "Change blah to date".
