ElementPlusError: [ElPagination] undefined

本文主要是介绍ElementPlusError: [ElPagination] undefined，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

报错原因：必传值total最初传入的值为undefined

解决：使用watch进行监听赋值

<el-pagination@size-change="handleSizeChange"@current-change="handleCurrentChange"v-model:current-page="index"v-model:page-size="size":page-sizes="pageSizes"layout="total, sizes, prev, pager, next":total="totalNum":background="true"></el-pagination>setup(props, context) {const pageInfo = reactive({index:1,size: 10,totalNum:0})watch(() => [props.pagemeta.page, props.pagemeta.page_size, props.pagemeta.total] , (newValue, oldValue) => {pageInfo.index = newValue[0];pageInfo.size = newValue[1];pageInfo.totalNum = newValue[2];// console.log(`原值为${oldValue}`)   // console.log(`新值为${newValue}`)  })return {...toRefs(pageInfo),}
}
