它在您使用Chrome模拟器时有效,但在使用ios 10 safari浏览器时无效.

下面是我用来聚焦元素的代码.

var rvMobileApp = angular.module('rvMobileApp.shared.directive');

market.actions.ts

  constructor(public payload: {error: any}) {}
}

export type MarketActions =
  | LoadMarket
  | UpdateMarket
  | LoadMarketFailure;

market.reducers.ts

export function marketReducer(state = initialState, action: MarketActions): …
