前言
大家好 我是歌谣 今天继续给大家带来一个V3 ts实现的todolist的项目
目录结构
主要代码
TodoInput----index.vue
代码语言：javascript复制<template>
<div>
<input type="text" v-model="todoValue" @keyup="setTodoValue"/>
</div>
</template>
<script lang="ts">
import { defineComponent,reactive,ref } from 'vue';
import {IUseTodo, useTodo} from "../../hooks/index"
export default defineComponent({
name:"TodoInput",
setup(){
const todoValue=ref<string>("")
const setTodoValue=(e:KeyboardEvent)=>{
console.log(todoValue.value)
const {setTodo}:IUseTodo=useTodo()
if(e.keyCode===13&&todoValue.value.trim().length){
setTodo(todoValue.value)
todoValue.value=''
}
}
return {
todoValue,
setTodoValue
}
}
})
</script>
<style>
</style>TodoList---index.vue
代码语言：javascript复制<template>
<todo-item
v-for="(item, index) of todoList"
