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 class="form-signin-heading">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>

</div> <!-- /container -->

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.
