问题 I\'m using the vue-cli scaffold for webpack My Vue component structure/heirarchy currently looks like the following: App PDF Template Background Dynamic Template Image Static Template Image Markdown At the app level, I want a vuejs component method that can aggregate all of the child component\'s data into a single JSON object that can be sent off to the server.

But there exist a few little grey areas, mostly from an implementation standpoint. This one I feel is good by design, but don\'t know if it contradicts the Vuex cycle of uni-directional data flow. Basically, is it considered good practice to return a promise(

vuex 是一个专门为vue.js应用程序开发的状态管理模式。 这个状态我们可以理解为在data中的属性,需要共享给其他组件使用的部分。 也就是说,是我们需要共享的data,使用vuex进行统一集中式的管理。 vuex中,有默认的五种基本的对象: state:存储状态(变量) getters:对数据获取之前的再次编译,可以理解为state的计算属性。我们在组件中使用 $sotre.getters.fun() mutations:修改状态,并且是同步的。在组件中使用$store.commit('',params)。这个和我们组件中的自定义事件类似。 actions:异步操作。在组件中使用是$store.dispath('') modules:store的子模块,为了开发大型项目,方便状态管理而使用的。这里我们就不解释了,用起来和上面的一样。 下面我们正式开始,一步步使用vuex 来源: https://www.cnblogs.com/Rivend/p/11932178.html
