vue+elementui 實現新增和修改共用一個彈框的完整代碼

element-ui是由餓瞭麼前端團隊推出的一套為開發者、設計師和產品經理準備的基於Vue.js 2.0的桌面組件庫,而手機端有對應框架是 Mint UI 。整個ui風格簡約,很實用,同時也極大的提高瞭開發者的效率,是一個非常受歡迎的組件庫。

一、新增

1、新增按鈕

2、新增事件 在methods中,用來打開彈窗,
dialogVisible在data中定義使用有true或false來控制顯示彈框

**3、新增確定,彈框確定事件 ,新增和修改共用一個確定事件,使用id區別

**3、新增事件

調新增接口,判斷是否有id,沒有就調新增接口

二、修改

2-1、修改按鈕 ,表格行編輯按鈕使用scope.row拿到當前行的數據

2-2、修改事件, 把當前行數據賦值給表單,就把當前行數據回顯出來瞭

2-3、修改事件

修改接口,判斷是否有id,有就調修改接口**

下面直接上代碼瞭
