Question

如下，如何获取children然后更新到father.children中，页面就可以列表展示了

state: {
    father: [
        {
            name: 'wang',
            children: []
        }
    ]
}


action: {
    getChildren(fatherId).then(children => {
        // 获得children，如何更新到father.children中
    });
}

Answer 1

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

大概这样吧，去看看文档吧
