SPA项目开发之CRUD+表单验证

一、表单验证

效果

二、crud（增删改查）

一、表单验证

所需表单

<!-- 编辑界面 -->
		<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
			<el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
				<el-form-item label="文章标题" prop="title">
					<el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
				</el-form-item>
				<el-form-item label="文章内容" prop="body">
					<el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
				</el-form-item>
			</el-form>
			<div slot="footer" class="dialog-footer">
				<el-button size="small" @click="closeDialog">取消</el-button>
				<el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
			</div>
		</el-dialog>

表单验证的规则（校验）都放入Articles.vue

data() {
			return {
				listData: [],
				formInline: {
					page: 1,
					rows: 10,
					title: ''
				},
				total: 0,
				title: '',
				editFormVisible: false,
				editForm: {
					title: '',
					body: '',
					id: 0
				},
				rules: {
					title: [{
							required: true,
							message: '请输入活动名称',
							trigger: 'blur'
						},
						{
							min: 3,
							max: 5,
							message: '长度在 3 到 5 个字符',
							trigger: 'blur'
						}
					],
					body: [{
						required: true,
						message: '请输入活动名称',
						trigger: 'blur'
					}]
				}
			};
		},
