Question

我现有代码的一小段。我将每个“显示” div的内容复制到“结果” div中。我有两个问题-首先，我必须单击两次单选按钮才能使其启动。其次，我要替换“结果” div的内容，而不是附加内容。我尝试了.html，但没有任何乐趣。

          func validatePasscode(passcode: String,
                  successBlock: @escaping (Event?) -> Void,
                  failureBlock: @escaping (Error) -> Void)
    {
       let passcodeURL = URL (string: "\(PASSCODE_CHECKER_URL)/\(passcode)")


Alamofire.request(passcodeURL!, method: .get).responseJSON { (response) in
        print(response)

       if let error = response.error
       {
        failureBlock(error)
        return
    }

            if let passcodeJSON = response.result.value as? [[String : Any]],
                let passcodeObj = passcodeJSON.first {
                print(passcodeObj)
                let event = Event.init(JSON: passcodeObj);
                successBlock(event)
        }

        }

}

我想你想喜欢它：-

当您单击按钮时，这里有两个divs和一个按钮，然后.div1的内容被复制到.div2

$(document).ready(function(){
  $('body').on('click', 'button', function(){

    $('.loop').each(function(index, elem){
      var div1Content = $(elem).find('.div1').html();
      $(elem).find('.div2').html(div1Content);
    });
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    <button>replace content</button>    <br><br>


<div class="loop">
<div class="div1">This is first div -- loop 1</div>
<div class="div2">this is second div -- loop 1</div>
</div>

<br>
<div class="loop">
    <div class="div1">This is first div -- loop 2</div>
    <div class="div2">this is second div -- loop 2</div>
    </div>

复制div的内容以替换另一个div中的内容
