```html

import Loading from 'vue-loading-overlay';
import 'vue-loading-overlay/dist/css/index.css';
export default {
data() {
return {
isLoading: false,
fullPage: true
}
},
components: {
Loading
},
methods: {
doAjax() {
this.isLoading = true;
// simulate AJAX
setTimeout(() => {
this.isLoading = false
}, 5000)
},
onCancel() {
console.log('User cancelled the loader.')
}
}
}
```
### As plugin
Initialise the plugin in your app
```js
import {createApp} from 'vue';
import {LoadingPlugin} from 'vue-loading-overlay';
import 'vue-loading-overlay/dist/css/index.css';
// Your app initialization logic goes here
const app = createApp({});
app.use(LoadingPlugin);
app.mount('#app');
```
Then use the plugin in your components
```html
Full page?
Login
export default {
data() {
return {
fullPage: false
}
},
methods: {
submit() {
let loader = this.$loading.show({
// Optional parameters
container: this.fullPage ? null : this.$refs.formContainer,
canCancel: true,
onCancel: this.onCancel,
});
// simulate AJAX
setTimeout(() => {
loader.hide()
}, 5000)
},
onCancel() {
console.log('User cancelled the loader.')
}
}
}
```
#### or same with Composition API
```html
import {ref, inject} from 'vue'
import {useLoading} from 'vue-loading-overlay'
const $loading = useLoading({
// options
});
// or use inject without importing useLoading
// const $loading = inject('$loading')
const fullPage = ref(false)
const submit = () => {
const loader = $loading.show({
// Optional parameters
});
// simulate AJAX
setTimeout(() => {
loader.hide()
}, 5000)
}
```
## Available props
The component accepts these props:
| Attribute | Type | Default | Description |

| can-cancel | Boolean | `false` | Allow user to cancel by pressing ESC or clicking outside |
| on-cancel | Function | `()=>{}` | Do something upon cancel, works in conjunction with `can-cancel` |
| is-full-page | Boolean | `true` | When `false`; limit loader to its container^ |
| transition | String | `fade` | Transition name |
| color | String | `#000` | Customize the color of loading icon |
| height | Number | * | Customize the height of loading icon |
