javascript - Questions about bootstrap form validation

The bootstrap set in the backend can satisfy most of the styles in terms of style. There is an issue with form submission, which uses the ready-made bootstrap template. The code is as follows

<code>  <form class="form-signin">
    <h2 id="Please-sign-in">Please sign in</h2>
    <label for="inputEmail" class="sr-only">Email address</label>
    <input type="email" id="inputEmail" class="form-control" placeholder="Email address" required autofocus>
    <label for="inputPassword" class="sr-only">Password</label>
    <input type="password" id="inputPassword" class="form-control" placeholder="Password" required>
    <div class="checkbox">
      <label>
        <input type="checkbox" value="remember-me"> Remember me
      </label>
    </div>
    <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
  </form>

</code>

Regarding the method of form verification, there is no introduction on the official website. I know what require means, but I want to know where to find the introduction on this aspect, but I can’t find it on the official website. Thank you everyone

Because I wrote ajax to submit asynchronously, but it didn’t work. I want to use the verification form that comes with bs to do asynchronous submission. Thank you

Simple.

<code>$("form").submit(function(e){
    e.preventDefault();   // disabled default action
    // do something and ajax ....
    $.post("url", $("form").serializeArray())
    .done(function(){})
    .failed(function(){})
    
  });</code>

Before submitting the form data to ajax for processing, write a function to verify the data first. If successful, it will be handed over to ajax, and if it fails, a prompt message will be returned.

Write the server address of the action in the form tag.
