main.js
import 'vue-loading-overlay/dist/css/index.css'
app.component('vue-loading', VueLoading)
// app.use(VueLoading) --> component로 이동
LoadingOverlayView.vue
<template>
<div class="vl-parent">
<vue-loading
v-model:active="isLoading"
:can-cancel="true"
:on-cancel="onCancel"
:is-full-page="fullPage"
/>
<label><input type="checkbox" v-model="fullPage" />Full page?</label>
<button class="btn btn-primary me-2" @click.prevent="doAjax">
fetch Data
</button>
<button class="btn btn-danger" @click.prevent="onCancel">Cancel</button>
</div>
</template>
<script>
export default {
data() {
return {
isLoading: false,
fullPage: true
}
},
methods: {
doAjax() {
this.isLoading = true
// simulate AJAX
setTimeout(() => {
this.isLoading = false
}, 5000)
},
onCancel() {
this.isLoading = false
console.log('User cancelled the loader.')
}
}
}
</script>
우선 위와 같이 수정하니까 되는데
조금 단순하게 하는 방법은 없을까요?
