SPA项目之CRUD+表单验证
1. 表单验证
Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
并将Form-Item的prop属性设置为需校验的字段名即可
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="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>
rules表单验证
rules: { title: [{ required: true, message: '请输入文章标题', trigger: 'blur' }, { min: 3, max: 5, message: '文章标题长度在 3 到 5 个字符', trigger: 'blur' } ], body: [{ required: true, message: '请输入文章内容', trigger: 'blur' }]
