我Error TS2554: Expected 0 arguments, but got 4在 observable 的管道中有一个getHappyDays()

getHappyDays()Observable 返回 a Observable<HttpResponse<IHappyDays>> | Observable<HttpErrorResponse>，我已经包含了一个 stackblitze 来更好地展示问题

 resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):
    Observable<IHappyDays> | Observable<never> {

    return this.happyService.getHappyDays()
      .pipe(//=>error thrown here
        first(),
        mergeMap((res) => {
          return of(res.body)
        })
      )
  }

极客!

我们都知道名为国际电话输入的真棒插件,有没有办法将它自己的验证方法绑定intlTelInput("isValidNumber")到jquery验证？

intlTelInput("isValidNumber") 返回真,如果真或假,如果假

下面还有更多细节!:

var handleContactFormValidation = function () {

    var value_form = $('#contact_form');//form i would like to validate where phone field is in!
    var value_error = $('.alert-danger', value_form);
    var value_success = $('.alert-success', value_form);
    value_form.validate({
        errorElement: 'span', //default input error message container
        errorClass: 'help-block help-block-error', // default input error message class
        focusInvalid: false, // do not focus the last invalid input
        ignore: "", // validate all fields including form hidden input
        rules: { …

使用CKeditor角度分量如何设置编辑器高度？

根据文档，可以通过将编辑器样式设置为：

 min-height: 500px !important;

但这不起作用！

我只是无法弄清楚 shaka 播放器如何能够解密我的 CENC 保护内容，即使我在播放器配置中提供了无效的解密密钥。

player.configure({
    drm: {
      clearKeys: {
        '6FepeJBbmaiozSMs18vPfA==': '6FepeJBbmaiozSMs18vPfA==', // ==> invalid key
        '6FepeJBbmaiozSMs18vPfA==': '6FepeJBbmaiozSMs18vPfA==', // ==> invalid key
      }
    }
  })   

这是给打包程序的参数

当我通过点击此URL请求特定国家/地区城市时,将获取太多无用的json数据:

http://api.geonames.org/searchJSON?username=ksuhiyp&country=us&maxRows=1000

这会返回太多的json字段,你可以看到,问题很热,查询只能获得城市,国家名称？
