封装组件 AmisComponent
<template>
<div id="amisid" ref="boxRef"></div>
</template>
<script setup lang="ts">
import {defineProps,watch,ref} from "vue"
import {ElMessage} from 'element-plus'

动态渲染组件 LowcodeEngine
<template>
<amisComponent :formid="formid" :formjson="formjson"></amisComponent>
</template>
<script setup lang="ts">
import {reactive, watch, ref} from "vue"
import amisComponent from "../amis/AmisComponent.vue"
import {useRoute,useRouter} from 'vue-router'
const route = useRoute()
const router = useRouter()
const formid = ref('')
const formjson = ref({})
watch(()=> router.currentRoute, (data)=>{
let _router:any = data.value
formid.value = res.result.id
formjson.value = {"type": "page","title": "标题","body": "Hello World!"}
// TODO 根据绑定菜单获取页面JSON
},
{immediate: true,deep: true}
)
</script>
路由处理
import request from '@/utils/request'
import Layout from '@/components/layout/Index.vue'
const modules = import.meta.glob('../views/**/**.vue')
const layoutModules = import.meta.glob("../components/layout/**.vue")
// 根据菜单构建动态路由
export const filterRouter = (routers:any, level:any) => {
level = level || 0
const accessedRouters = routers.filter( (router:any) => {
if (router.isShow) {
router.component = layoutModules[`../components/layout/LowcodeEngine.vue`]
if (router.children && router.children.length) {
router.children = filterRouter(router.children, level + 1)
}
return true
}
return false
})
return accessedRouters
}
