如何解决'来自注册为“被动”的侦听器的“ touchmove”事件上的调用“ preventDefault（）”被忽略。 '

Question

我正在开发一个Web应用程序。但是在智能手机中，我遇到了一些我不知道它来自哪里的问题。

public class MyViewModel : BaseViewModel
{
    public DelegateCommand<string> FilterOccupationsListCommand { get; }
    public MyViewModel()
    {
        FilterOccupationsListCommand = new DelegateCommand<string>(FilterOccupationsList);
    }
    private void FilterOccupationsList(string query)
    {
        if (!string.IsNullOrWhiteSpace(query))
        {
            FilteredOccupationsVisible = true;
            var searchResult = Occupations.Where(x => x.Name.ToLower().Contains(query));
            FilteredOccupations = new ObservableCollection<Occupation>(searchResult);
        }
        else
            FilteredOccupationsVisible = false;
    }

    private Occupation _occupation;
    public Occupation Occupation
    {
        get => _occupation;
        set
        {
            SetProperty(ref _occupation, value);
            SearchText = value.Name;
        }
    }

    private string _name;
    public string Name { get => _name; set => SetProperty(ref _name, value); }
    private string _searchText;
    public string SearchText 
    { 
        get => _searchText; 
        set { 
              SetProperty(ref _searchText, value); 
              FilteredOccupationsVisible = false;
            } 
    }

    private bool _filteredOccupationsVisible;
    public bool FilteredOccupationsVisible { get => _filteredOccupationsVisible; set => SetProperty(ref _filteredOccupationsVisible, value); }

    public ObservableCollection<Occupation> _filteredOccupations = new ObservableCollection<Occupation>();
    public ObservableCollection<Occupation> FilteredOccupations { get => _filteredOccupations; set { SetProperty(ref _filteredOccupations, value); } }
}

它可以在PC上运行，但是如果我使用移动设备，它将停止工作。

控制台中显示的错误：
