  • loading-indicator is a child component implemented with default animation effect for the refresh component.

Events

  • onloading triggered when loading

Restrictions

  • refresh/loading does not support remove action, Weex 0.9 will fix it.
  • refresh/loading despite setting with display=’hide’, the refresh/loading view will still appear when scrolling due to known issues. it can be fixed with a another display=’hide’ when the refresh/loading should be hidden.
  • refresh/loading can only be hidden or displayed with an attribute display with value of show or hide. And there should be a statement of display=’hide’ when display=’show’ shows up in an event function, or your scroller may not response to user inputs.
