域名預(yù)訂/競(jìng)價(jià),好“米”不錯(cuò)過(guò)
這篇文章主要為大家詳細(xì)介紹了vue+iview實(shí)現(xiàn)分頁(yè)及查詢功能,文中示例代碼介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們可以參考一下
vue+iview 分頁(yè)及刪、查功能實(shí)現(xiàn)
首先要想實(shí)現(xiàn)分頁(yè)功能必須得知道 當(dāng)前頁(yè)碼、每頁(yè)大小、總數(shù)目。
iview對(duì)分頁(yè)的功能支持還是很強(qiáng)大的,有很多鉤子函數(shù)
具體實(shí)現(xiàn)看后端返回的數(shù)據(jù)
<template>

<Input type="text" search enter-button placeholder="根據(jù)施工人員姓名查找" v-model="peopleName" @input="search"/>
<Table width="100%" :columns="peopleCol" :data="peopleDat"></Table>
<!--通過(guò)sync修飾符可以動(dòng)態(tài)獲取頁(yè)碼-->
