我试图用Vue和Vee验证来模拟Bootstrap form validation styling.
为了获得Boostrap验证错误消息，当出现验证错误时，输入本身必须有is-invalid个类出现.此外，错误消息元素当然必须有invalid-feedback类.
当出现验证错误时，我很难向输入中添加is-invalid个类.
在Vee validate 3中，我能够用this guide控制输入元素的类.但它似乎遭到了反对.
This是一个可以使用的代码Sandbox .没什么特别的，直接从Veevalidate example开始.
<template>
<div id="app">
<Form @submit="onSubmit">
<Field name="email" type="email" :rules="validateEmail" class="form-control"/>
<ErrorMessage class="invalid-feedback" name="email" />
<button class="btn btn-primary">Sign up</button>
</Form>
</div>
</template>
<script>
import {
Form,
Field,
ErrorMessage
} from "vee-validate";
export default {
components: {
Form,
Field,
ErrorMessage,
},
methods: {
onSubmit(values) {
console.log(values, null, 2);
},
validateEmail(value) {
// if the field is empty
if (!value) {
return "This field is required";
}
// if the field is not a valid email
const regex = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
if (!regex.test(value)) {
return "This field must be a valid email";
}
// All is good
return true;
},
},
};
</script>
<style>
span {
display: block;
margin: 10px 0;
}
</style>版本
