• SPA项目开发之CRUD+表单验证


    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-form-item label="活动名称" prop="name">
    
       <el-form :model="ruleForm" :rules="rules" ref="ruleForm"

     

    有多个表单,怎么在提交进行区分?

            我们在rules这里写了对表单的验证规则,但是我们如何在methods里进行指定的表单进行认证,

            所以我们一开始就在el-form里写了 ref="ruleForm",我们在methods里就可以用

     

    清空表单验证信息

     

    this.$refs[formName].resetFields();
