# Ajax
|
|
|
|
|
|
|
|
|
|
`Ajax` is a droplab plugin that allows for retrieving and rendering list data from a server.
|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
|
|
Add the `Ajax` object to the plugins array of a `DropLab.prototype.init` or `DropLab.prototype.addHook` call.
|
|
|
|
|
|
|
|
|
|
`Ajax` requires 2 config values, the `endpoint` and `method`.
|
|
|
|
|

|
|
|
- `endpoint` should be a URL to the request endpoint.
|
|
|
|
|
- `method` should be `setData` or `addData`.
|
|
|
|
|
- `setData` completely replaces the dropdown with the response data.
|
|
|
|
|
- `addData` appends the response data to the current dropdown list.

```html
|
|
|
|
|
<a href="#" id="trigger" data-dropdown-trigger="#list">Toggle</a>
|
|
|
|
|
<ul id="list" data-dropdown><!-- ... --><ul>
|
|
|
|
|
```
|
|
|
|
|
```js
|
|
|
|
|
const droplab = new DropLab();
|
|
|
|
|
|
|
|
|
|
const trigger = document.getElementById('trigger');
|
|
|
|
|
const list = document.getElementById('list');
|
|
|
|
|
|
|
|
|
|
droplab.addHook(trigger, list, [Ajax], {
|
|
|
|
|
Ajax: {
|
|
|
|
|
endpoint: '/some-endpoint',
|
|
|
|
|
method: 'setData',
|
|
|
|
|
},
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Optionally you can set `loadingTemplate` to a HTML string. This HTML string will
|
|
|
|
|
replace the dropdown list whilst the request is pending.
|
|
|
|
|
|
|
|
|
|
Additionally, you can set `onError` to a function to catch any XHR errors.
