Question

输入数字后，我必须自动聚焦下一个输入元素。

我的HTML：

public static void Main(string[] args)
        {
            Task.WaitAll(IntegrateWithSlackAsync());
        }

        private static async Task IntegrateWithSlackAsync()
        {
            var webhookUrl = new Uri("https://hooks.slack.com/services/TmyHook");  
            var slackClient = new SlackClient(webhookUrl);
            while (true)
            {
                Console.Write("Type a message: ");
                var message = Console.ReadLine();
                Payload testMessage = new Payload(message);
                var response = await slackClient.SendMessageAsync(testMessage);
                var isValid = response.IsSuccessStatusCode ? "valid" : "invalid";
                Console.WriteLine($"Received {isValid} response.");
                Console.WriteLine(response);
            }
        }
    }
}

public class SlackClient
{
        private readonly Uri _webhookUrl;
        private readonly HttpClient _httpClient = new HttpClient {};

        public SlackClient(Uri webhookUrl)
        {
            _webhookUrl = webhookUrl;
        }

        public async Task<HttpResponseMessage> SendMessageAsync(Payload payload)
        {

            var serializedPayload = JsonConvert.SerializeObject(payload);

            var stringCont = new StringContent(serializedPayload, Encoding.UTF8, "application/x-www-form-urlencoded");

            var response = await _httpClient.PostAsync(_webhookUrl, stringCont);

            return response;
        }
    }
}

在我的JavaScript中，我有：

    public class Payload
{
    public string token = "my token stands here";
    public string user = "my userID";
    public string channel = "channelID";
    public string text = null;

    public bool as_user = true;


    public Payload(string message)
    {
        text = message;
    }
}

这实际上可以正常工作，事情是当我试图在手机上使用它时，它保持在相同的输入状态，而不会转到下一个。我真的需要帮助。

谢谢！

在触发keyup事件之前，手机的浏览器未在input元素内接收值。因此if ($(this).val())目前为假。您需要使用其他事件类型（例如input）来避免这种情况。

更多信息和游乐场：

$('.inp-num').on('input', function() {
 if ($(this).val()) {
   $(this).next().focus();
 }
});

为什么我的js函数不能在计算机上工作，而不能在手机上工作？
