In this lesson, we create a set of tabs with Alpine JS, where only the content of the currently active tab is visible. To do this, we define an activeTab state value with x-data. We then wire up our buttons to change the value ofactiveTabon click, and usex-showto determine if the tab content should be visible or not, based on the value ofactiveTab`.
We also take control of the class attribute with x-bind, and we conditionally output an "active" class based on, you guessed it, the value of activeTab.
<div x-data="{activeTab: 0}"> <div> <!-- :class: means bind to class attr, just like [ngClass] in Angular--> <button @click="activeTab = 0" :class="{‘active‘: activeTab === 0}">Tab 1</button> <button @click="activeTab = 1" :class="{‘active‘: activeTab === 1}">Tab 2</button> <button @click="activeTab = 2" :class="{‘active‘: activeTab === 2}">Tab 3</button> </div> <div> <div x-show="activeTab === 0"><p>I am the content of tab number one, and I think I just won! ??</p></div> <div x-show="activeTab === 1"><p>Heya! I root for number two, and so should you! ??</p></div> <div x-show="activeTab === 2"><p>Haha nice one, but I am number three, and now it‘s all about me! ??</p></div> </div> </div>
