表单验证rules 绑定是规则 也可以自定义规则,:model是表单的数据源 el-form-item 标签里面prop的名字要和数据源的名字一致,才能验证生效 ;提交时调用this.$refs[formName].validate()方法,refs['这个值是和form标签里面ref值要一致']
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
<el-form-item label="活动名称" prop="name"> <el-input v-model="ruleForm.name"></el-input> </el-form-item>
<el-form-item label="即时配送" prop="delivery"> <el-switch v-model="ruleForm.delivery"></el-switch> </el-form-item>
<el-form-item label="特殊资源" prop="resource"> <el-radio-group v-model="ruleForm.resource">
<el-radio label="线上品牌商赞助"></el-radio> <el-radio label="线下场地免费"></el-radio> </el-radio-group> </el-form-item>
<el-form-item label="活动形式" prop="desc"> <el-input type="textarea" v-model="ruleForm.desc"></el-input> </el-form-item>
<el-form-item>
<el-button type="primary" @click="submitForm('ruleForm')">立即创建</el-button>
<el-button @click="resetForm('ruleForm')">重置</el-button>
</el-form-item>
</el-form>

this.$refs[formName].validate((valid) => { if (valid) { alert('submit!');//这里一般调用提交接口
} else {

});
