一、Element UI中表格数据的删除
- 在表格数据的删除按钮下,进行绑定删除事件,
removeUserById()
。在这个是事件中,传入当前项的id
值,通过scope.row.id
就可以获得当前项的id值,代码如下:
<el-button type="danger" icon="el-icon-delete" size="mini" @click="removeUserById(scope.row.id)">el-button>
- 在
method
中,定义removeUserById()
方法,传入id
。在点击删除按钮以后,可以给一个消息提示,判断用户是否决定删除,可以引用Element UI
中的MessageBox
弹框。我们可以在引入MessageBox
以后,进行原型挂载,代码如下:
Vue.prototype.$confirm = MessageBox.confirm
- 在
method
中定义的removeUserById(id)
方法中,使用MessageBox
组件。由于this.$confirm
的返回值是一个promise
对象,所以可以使用async
和await
进行简化操作。如果用户确认删除,则返回值为字符串 confirm
。如果用户取消删除,则返回值为字符串 cancel
。在用户确认删除以后,调用删除的api
,传入当前项的id
值。如果状态码不为200
,说明删除失败,反之则删除成功。然后给一个删除成功的提示,更新数据列表,代码如下:
async removeUserById (id) {
const confirmResult = await this.$confirm('此操作将永久删除该用户, 是否继续?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
}).catch(() => {
this.$message({
type: 'info',
message: '已取消删除'
})
})
if (confirmResult !== 'confirm') {
return this.$message.info('已取消删除')
}
const {data: res} = await this.$http.delete('users/' + id)
if (res.meta.status !== 200) {
return this.$message.error('删除用户失败!')
}
this.$message.success('删除用户成功!')
this.getUserList()
}
