有没有一种方法可以在语义ui上使用promise和自定义验证

Question

Is there any way to use promise with a custom rule on semantic ui? I want to validate a field with my custom rule. If response of server is false field must be red. Here's what I'm trying to do.

$.fn.form.settings.rules.myCustomRule = function(param) {
let myPromise = this.get('api').r_get(allUrls.urlName, model);
  myPromise.then(
    response => {
        return true;
    }
  ).catch(
    error => {
        return false;
    }
  );
}

You can add error class to a div or input when the promise returns false. Would that work? Like this:

 function simulateServer(){ $('#serverresponse').addClass('error'); } 

 <link href="https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.3.3/semantic.css" rel="stylesheet"/> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="serverresponse" class="ui input"> <input type="text" placeholder="Search..."> </div> <br><br> <button onclick="simulateServer()">Contact Server</button> 

It wouldn't be possible with a custom rule promise, as it expects an immediate response.
