## AJAX Remote Option Loading
|
|
|
|
[](codepen://sagalbot/POMeOX?height=400)
|
|
|
|
The `onSearch` prop allows you to load options via ajax in a parent component
|
|
when the search text is updated. It is invoked with two parameters, `search` & `loading`.
|
|
|
|
```js
|
|
/**
|
|
* Accepts a callback function that will be run
|
|
* when the search text changes. The callback
|
|
* will be invoked with these parameters:
|
|
*
|
|
* @param {search} String Current search text
|
|
* @param {loading} Function Toggle loading class
|
|
*/
|
|
onSearch: {
|
|
type: Function,
|
|
default: false
|
|
},
|
|
```
|
|
|
|
The `loading` function accepts a boolean parameter that will be assigned
|
|
to the vue-select internal `loading` property. Call `loading(true)` to set the
|
|
`loading` property to `true` - toggling the loading spinner. After your
|
|
asynchronous operation completes, call `loading(false)` to toggle it off.
|
|
|
|
#### Disabling Filtering
|
|
|
|
When loading server side options, it can be useful to disable the
|
|
client side filtering. Use the `filterable` prop to disable filtering.
|
|
|
|
```js
|
|
/**
|
|
* When true, existing options will be filtered
|
|
* by the search text. Should not be used in
|
|
* conjunction with taggable.
|
|
*
|
|
* @type {Boolean}
|
|
*/
|
|
filterable: {
|
|
type: Boolean,
|
|
default: true
|
|
},
|
|
```
|
|
|
|
#### Loading Spinner
|
|
|
|
Vue Select includes a default loading spinner that appears when the loading class is present. The `spinner` slot allows you to implement your own spinner.
|
|
|
|
```html
|
|
<div class="spinner" v-show="spinner">Loading...</div>
|
|
```
|
|
|
|
#### Library Agnostic
|
|
|
|
Since Vue.js does not ship with ajax functionality as part of the core library, it's up to you to process the ajax requests in your parent component.
|
|
|
|
I recommend using [axios](https://github.com/axios/axios) for creating your applications HTTP layer,
|
|
or [`fetch()`](https://github.com/github/fetch) for simple requests.
