需求对表单填写字段进行标记有误和取消标记有误
方案 最新想到的方案推荐
定义一个存放错误信息的对象,然后再自定义一个验证规则,在这个验证规则中,通过当前验证字段的prop值,到存放错误信息的对象中获取对应的错误提示文案,如果获取到了,则说明,该字段存在标记有误,则让验证不通过,反之,则让验证通过
运行效果: 实现代码<template>
<div>
<h1>标记有误/取消标记有误:</h1>
<el-button @click="() => onMarkError(['markField', 'mustAndMarkField'])">
将第二个和最后一个标记有误
</el-button>
<el-button @click="() => onMarkError(['markField'])"
>将第二个标记有误</el-button
>
<el-button @click="() => onMarkError(['mustAndMarkField'])"
>将最后一个标记有误</el-button
>
<el-button
@click="() => onCancelMarkError(['markField', 'mustAndMarkField'])"
>
取消第二个和最后一个标记有误
</el-button>
<el-button @click="() => onCancelMarkError(['markField'])">
取消第二个标记有误
</el-button>
<el-button @click="() => onCancelMarkError(['mustAndMarkField'])">
取消最后一个标记有误
</el-button>
