使 html 按钮不会触发 node.js 中的 app.post

Question

I am using app.post to redirect the user. when the user presses the first button, I do not want them to be redirected, but i still want the first button to send the value. I cant put the <form> above the first button, so how do i make the first button not trigger the app.post.

You can add attribute type="button" to button tag to remove this behavior. Example:

<form action="/" method="post">
  First name: <input type="text" name="fname">

  <button>I'll submit form</button>
  <button type="submit">I'll submit form too</button>
  <button type="button">I'm just a button so I don't submit anything</button> <-- It's work
</form>
