我是初學者網路開發人員。我做小碎屑。這是我的第一個應用程式:)
我有這個代碼：
<template>
<CRow>
<CCol col="12">
<CCard no-header>
<CCardBody>
<h3>
Create Note
</h3>
<CAlert
:show.sync="dismissCountDown"
color="primary"
fade
>
({{ dismissCountDown }}) {{ message }}
</CAlert>
<CInput label="Title 123" type="text" id="title" placeholder="Title" v-model="note.title"
v-bind:class="{ 'text-danger invalid': hasError }"></CInput>
<CInput textarea="true" label="Content" id="content" :rows="9" placeholder="Content.."
v-model="note.content" v-bind:class="{ 'text-danger invalid': hasError }"></CInput>
<CInput label="Applies to date" type="date" id="applies_to_date" v-model="note.applies_to_date" v-bind:class="{ 'text-danger invalid': hasError }"></CInput>

</CSelect>

<template>

</div>
</template>
<div class="text-center py-5">
<CButton color="success" @click="store()" class="mr-3">Zapisz</CButton>
<CButton color="primary" @click="goBack">Cofnij</CButton>

</script>
<style>
.invalid input, textarea, select, checkbox {
border-color: red;
}
</style>
此時，它的作業方式是在單擊“保存”后自動發生字體顏色和輸入邊框的更改。
我希望此邊框僅添加到空輸入。
我怎樣才能做到這一點？
請幫我 ：）

您必須在系結類中添加條件
<CInput label="Title 123" type="text" id="title" placeholder="Title" v-model="note.title"
v-bind:class="[note.title == '' ? 'text-danger invalid' : '']"></CInput>
uj5u.com熱心網友回復：
每個輸入都需要一個錯誤指示器。嘗試在物件中放置和查找錯誤。
模板
<CInput label="Title 123" type="text" id="title" placeholder="Title" v-model="note.title"
v-bind:class="{ 'text-danger invalid': errors['title']}"></CInput>
<CInput textarea="true" label="Content" id="content" :rows="9" placeholder="Content.."
v-model="note.content" v-bind:class="{ 'text-danger invalid': errors['content'] }"></CInput>
資料
data: () => {
return {
errors: {
title: false,
content: false,
},
note: {
title: '',
content: '',
applies_to_date: '',
status_id: null,
note_type: '',
},
檢查輸入法
checkInputs() {
let errorCount = 0;
// check each input individually
if (!this.note.title){
this.errors['title'] = true;
errorCount ;
}
else {
this.errors['title'] = false;
}
if (!this.note.content){
this.errors['content'] = true;
errorCount ;
}
else {
this.errors['content'] = false;
}
// TODO need to check the rest
return errorCount;
}
