1.element-plus中form表单的ref不能跟ts定义的一个变量名一致，不然导致input无法输入

2. element-plus的rules trigger的blur和change一起写方式改变了
3. 监听watch方式修改
4.缓存处理

5.路由跳转



6.组件工程化

components/index.ts

const requireComponent = require.context('./', true, /\.vue$/)
const components:any = []

requireComponent.keys().map(file => {
  components.push(requireComponent(file).default)
})

const install = function (Vue:any) {
  components.map((component:any) => {
    Vue.component(component.name, component)
  })
}

if (typeof window !== 'undefined' && window.Vue) {
  install(window.Vue)
}
const CSUI = {
  install,
  ...components
}
export default CSUI

因为会报window错误，所以要在shims-vue.d.ts里添加如下代码

declare interface Window {
  Vue: any
}

main.ts

import CSUI from '@/components/index.ts'
createApp(App).use(store).use(router).use(elementPlus, { locale }).use(CSUI).mount('#app')

7.父子组件通讯
父传子


子传父


8.接口代理，实现调用接口
request/index.ts

import axios from 'axios'

const service = axios.create({
    baseURL: '/api',
    timeout: 10000
})

service.interceptors.request.use(function(config:any):any {
    config.headers.Authorization = `Bearer 05f894b3-144f-48ea-bcc5-328ae49d7bf8`
    return config
})

service.interceptors.response.use(function(res:any):any {
    return res.data
})

export default service

api/index.ts

export * from './role/index'

api/role/index.ts

import http from '@/request/index'

export function getCode(params:any = {}) {
    return http.get('/code', { params })
}

代理

module.exports = {
    devServer: {
        host: '127.0.0.1',
        port: 80,
        proxy: {
            '^/api': {
                target: '',
                secure: true,
                changeOrigin: true,
                pathRewrite: {
                    '^/api': ''
                }
            }
        }
    }
}

9.table组件的封装
父组件

<template>
     <table-list
          @getInit="getInit"
          @detail="detail"
          @edit="edit"
          @deleted="deleted"
      ></table-list>
</template>

<script>
    import { roleList } from '@/api/index'
    import { defineComponent, provide, reactive, ref, onMounted } from 'vue'
    import { ElMessageBox, ElMessage } from 'element-plus'
    export default defineComponent({
        setup(prop, context) {
            let data = {
                tableData: ref([]),
                column: [
                    { label: '角色编号', prop: 'roleId', width: 150},
                    { label: '角色名称', prop: 'roleName'},
                    { label: '权限字符', prop: 'roleKey', width: 200},
                    { label: '创建时间', prop: 'createTime', width: 200},
                ],
                loading: ref(true),
                tableBtn: [

                    { text: '删除', method: 'deleted', type: 'danger' }
                ],
                conditionData: [

                totalList: ref(0),
                filterData: ref({
                    roleName: '',
                    roleKey: '',
                    create_time: '',
                    pageNum: 1,
                    pageSize: 10
                })
            }
            const methods = {
                getInit() {
                    methods.roleList()
                },
                roleList() {
                    roleList({
                        ...data.filterData.value
                    }).then(res => {
                        data.tableData.value = res.rows
                        data.loading.value = false
                        data.totalList.value = res.total
                    })
                },
                detail(row) {
                    console.log(row)
                },
                edit(row) {
                    console.log(row)
                },
                deleted(row) {
                    ElMessageBox.confirm('此操作将永久删除该文件, 是否继续?', '提示', {
                        confirmButtonText: '确定',
                        cancelButtonText: '取消',
                        type: 'warning'
                    }).then(res => {

                            message: '删除成功'
                        })
                    }).catch(res => {
                        
                    })
                },
            }
            provide('data', data)

        }
    })

10.引入图表echarts,后续改为组件
main.ts

import * as echarts from 'echarts'
const app = createApp(App)
app.config.globalProperties.$echarts = echarts

home.vue

<template>
  <echart-init></echart-init>
</template>

<script lang="ts">
import { defineComponent } from 'vue'
export default defineComponent({

})
</script>

echatInit.vue

<template>
    <div :id="echartId" style="width: 100%; height: 100%"></div>
</template>

<script>
    import { defineComponent, ref, getCurrentInstance, onMounted } from 'vue'
    import { uniqueId } from 'lodash'
    export default defineComponent({
        name: 'echart-init',
        setup(prop,context) {
            const echartId = ref(uniqueId('echartsId_'))
