web前端-js教程
这篇文章主要介绍了vue + vuex todolist的实现示例代码，我觉得挺不错的，现在分享给大家，也给大家做个参考。

最近有空重新看了一下vuex,然后又写了一个todolist小demo,原理比较简单,主要是自己规范了一下代码的写法.

效果图
根组件
todo list demo
import { createNamespacedHelpers } from vueximport TypeFilter from ./filterimport AddTodo from ./addTodoimport TodoItem from ./itemconst { mapState, mapMutations } = createNamespacedHelpers(TodoList)export default { name: odo-list-demo, components: { TypeFilter, TodoItem, AddTodo }, computed: { ...mapState([list, ypes, filter]) }, methods: { ...mapMutations([ handleAdd, handleRemove, handleToggle, handleUpdateFilter ]) }}@import ./style.scss;过滤条件组件
{{item}} export default { name: ype-filter, props: [ ypes, filter, handleUpdateFilter], methods: { filterClass(filter) { return { filter: true, active: filter === this.filter } } }}@import ./style.scss;
添加待办组件
export default { name: add-todo, props: [handleAdd], methods: { add(e) { const val = e.target.value.trim() if (val) { this.handleAdd({ id: new Date().getTime(), message: val, status: false }) e.target.value = \ } } }}@import ./style.scss;
单个待办事项组件
{{index+1}}. {{data.message}} Delete
export default { name: odo-items, props: [data, filter, index, handleRemove, handleToggle], computed: { show() { return ( this.filter === ALL || (this.filter === UNDO && !this.data.status) || (this.filter === DONE && this.data.status) ) } }, methods: { dateFormat(time) { const date = new Date(time) return `(${date.getFullYear()}-${date.getMonth() + 1}-${date.getDate()})` }, messageClass: status => ({ message: true, done: status }) }}@import ./style.scss;
vuex部分(模块)
const state = { list: [], types: [ALL, UNDO, DONE], filter: ALL}const mutations = { handleAdd(state, item) { state.list = [...state.list, item] }, handleRemove(state, id) { state.list = state.list.filter(obj => obj.id !== id) }, handleToggle(state, id) { state.list = state.list.map( obj => (obj.id === id ? { ...obj, status: !obj.status } : obj) ) }, handleUpdateFilter(state, filter) { state.filter = filter }}export default { namespaced: true, state, mutations}
上面是我整理给大家的，希望今后会对大家有帮助。
