## Tabs (Using Hyperscript)

This example shows how to load tab contents using htmx, and to select the "active" tab using Javascript.  This reduces some duplication by offloading some of the work of re-rendering the tab HTML from your application server to your clients' browsers.  

You may also consider [a more idiomatic approach](../tabs-hateoas) that follows the principle of [Hypertext As The Engine Of Application State](https://en.wikipedia.org/wiki/HATEOAS).

### Example Code

The HTML below displays a list of tabs, with added HTMX to dynamically load each tab pane from the server.  A simple [hyperscript](https://hyperscript.org) event handler uses the [`take` command](https://hyperscript.org/commands/take/) to switch the selected tab when the content is swapped into the DOM.  Alternatively, this could be accomplished with a slightly longer Javascript event handler.

```html
<div id="tabs" hx-target="#tab-contents" _="on htmx:afterOnLoad take .selected for event.target">
	<a hx-get="/tab1" class="selected">Tab 1</a>
	<a hx-get="/tab2">Tab 2</a>
	<a hx-get="/tab3">Tab 3</a>
</div>

<div id="tab-contents" hx-get="/tab1" hx-trigger="load"></div>
```

{% include demo_ui.html.liquid %}

<div id="tabs" hx-target="#tab-contents" _="on click take .selected for event.target">
	<a hx-get="/tab1" class="selected">Tab 1</a>
	<a hx-get="/tab2">Tab 2</a>
	<a hx-get="/tab3">Tab 3</a>
</div>

<div id="tab-contents" hx-get="/tab1" hx-trigger="load"></div>

<script src="https://unpkg.com/hyperscript.org"></script>
<script>
	onGet("/tab1", function() {
