更新時(shí)間：2022年03月03日 16:29:34 作者：陶然同學(xué)。
這篇文章主要為大家詳細(xì)介紹了Vue項(xiàng)目之學(xué)生管理系統(tǒng)實(shí)例，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，希望能夠給你帶來(lái)幫助
查詢學(xué)生
步驟1：設(shè)置導(dǎo)航
步驟2：添加路由
步驟3：創(chuàng)建頁(yè)面
步驟：
- 步驟1：準(zhǔn)備2個(gè)變量（pageInfo、studentVo）
- 步驟2：編寫查詢condition函數(shù)，接收參數(shù)num
- 步驟3：頁(yè)面加載成功時(shí)，查詢第一頁(yè)
- 步驟4：遍歷結(jié)果

步驟3：創(chuàng)建頁(yè)面
步驟：
- 創(chuàng)建數(shù)據(jù) 班級(jí)數(shù)組 和 學(xué)生對(duì)象
- 班級(jí)數(shù)據(jù)跟select綁定 table綁定學(xué)生對(duì)象
- 發(fā)送post請(qǐng)求添加學(xué)生

步驟1：設(shè)置導(dǎo)航
步驟2：添加路由
步驟3：創(chuàng)建頁(yè)面
步驟：
- 先獲得路由傳參傳過來(lái)的參數(shù) 存儲(chǔ)到data數(shù)據(jù)區(qū)域 cid
- 根據(jù)cid查詢到學(xué)生 存儲(chǔ)到student table對(duì)student進(jìn)行數(shù)據(jù)雙向關(guān)聯(lián)
- 修改學(xué)生信息 發(fā)送ajax請(qǐng)求
