wepy-redux中state更新后不能直接更新视图显示

Open thomasxlh opened this issue 6 years ago • 7 comments

@connect(
  {
    hisWords(state) {
      // return state.searchResultList.hisWords;  如果是执行这行的话，hisWords变化后，视图不会更新
      return [].concat(state.searchResultList.hisWords);  // 必须新开内存空间，否则更新hisWords后页面不会同步改变
    }
  }
)

hisWords作为参数会传递给子组件，然后用wx:for遍历显示。请问下这里是为什么需要新建对象，是因为隐藏执行$apply()的原因么?

异步action的话，确实是需要$aply的
