問題描述

如下，如何獲取children然后更新到father.children中，頁面就可以列表展示了

state: { father: [{ name: ’wang’, children: []} ]}action: { getChildren(fatherId).then(children => {// 獲得children，如何更新到father.children中 });}

問題解答

state: { father: [{ name: ’wang’, children: []} ]}, mutations:{updateChildren(state,children){ state.father[0].children = children;}},actions: { updateChildren({commit}){getChildren(fatherId).then(children => { // 獲得children，如何更新到father.children中 commit('updateChildren',children );}); }}

大概這樣吧，去看看文檔吧
