1、Element UI中表格數據的刪除
- 在表格數據的刪除按鈕下,進行綁定刪除事件,
removeUserById()
。在這個是事件中,傳入當前項的id
值,經過scope.row.id
就能夠得到當前項的id值,代碼以下:
<el-button type="danger" icon="el-icon-delete" size="mini" @click="removeUserById(scope.row.id)"></el-button>
複製代碼
- 在
method
中,定義removeUserById()
方法,傳入id
。在點擊刪除按鈕之後,能夠給一個消息提示,判斷用戶是否決定刪除,能夠引用Element UI
中的MessageBox
彈框。咱們能夠在引入MessageBox
之後,進行原型掛載,代碼以下:
Vue.prototype.$confirm = MessageBox.confirm
複製代碼
- 在
method
中定義的removeUserById(id)
方法中,使用MessageBox
組件。因爲this.$confirm
的返回值是一個promise
對象,因此可使用async
和await
進行簡化操做。若是用戶確認刪除,則返回值爲字符串 confirm
。若是用戶取消刪除,則返回值爲字符串 cancel
。在用戶確認刪除之後,調用刪除的api
,傳入當前項的id
值。若是狀態碼不爲200
,說明刪除失敗,反之則刪除成功。而後給一個刪除成功的提示,更新數據列表,代碼以下:
async removeUserById (id) {
const confirmResult = await this.$confirm('此操做將永久刪除該用戶, 是否繼續?', '提示', {
confirmButtonText: '肯定',
cancelButtonText: '取消',
type: 'warning'
}).catch(() => {
this.$message({
type: 'info',
message: '已取消刪除'
})
})
if (confirmResult !== 'confirm') {
return this.$message.info('已取消刪除')
}
const {data: res} = await this.$http.delete('users/' + id)
if (res.meta.status !== 200) {
return this.$message.error('刪除用戶失敗!')
}
this.$message.success('刪除用戶成功!')
this.getUserList()
}
