Vue.js 實現的 3D Tab選單

今天給大家帶來一款基於VueJS的3D Tab選單，它跟我們之前分享的許多CSS3 Tab選單不同的是，它可以隨著滑鼠移動呈現出3D立體的視覺效果，每個tab頁面還可以通過CSS自定義封面照片。它的核心是基於vue和bootstrap實現，因此擴充套件起來非常方便，你可以任意新增或者減少tab頁面數量，同時只要更新對應tab頁面的CSS程式碼即可，無須修改js程式碼。

HTML程式碼：

<div id="app-container" data-tilt >
  <div id="app">
    <vue-tabs id="tabs">
      <v-tab title="First Tab" class="tab" :selected="true">
        <div class="tab-content">
          <div class="tab-image first-image"></div>
          <div class="tab-content-text">
            <h1>First Header</h1>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt nu aliqua. Sollicit udin purus faucibus ornare aliquam ultrices sagittis orci a scelerisque a consectetur atna purus.</p>
          </div>
        </div>
      </v-tab>

      <v-tab title="Second Tab" class="tab">
        <div class="tab-content">
          <div class="tab-image second-image"></div>
          <div class="tab-content-text">
            <h1>Second Header</h1>
            <p>Ac tortor vitae purus faucibus ornare suspendisse uis tristique sed nisi. Consectetur libero id ax faucibus in ornare faucibus nislt udin purus fi faucibus ac ornare aliquam ultrices in purus faucibu.</p>
          </div>
        </div>
      </v-tab>

      <v-tab title="Third Tab" class="tab">
        <div class="tab-content">
          <div class="tab-image third-image"></div>
          <div class="tab-content-text">
            <h1>Third Header</h1>
            <p>Scelerisque fermentum dui faucibus in ornare id. Amet consectetur adipiscing elit duis tristique sollicitudin purus faucibus ornare aliquam ultrices sagittis nibh elit duis nubro tristique itae purus faucibus.</p>
          </div>
        </div>
      </v-tab>
    </vue-tabs>

  </div>

</div>

當然，你要引入vue指令碼庫和bootstrap指令碼庫：

<script src='js/vue.min.js'></script>
<script src='js/bootstrap.min.js'></script>

這個外掛的核心程式碼如下：

if (typeof window !== 'undefined' && window.Vue) {
  window.Vue.use(VueTabsPlugin);

Object.defineProperty(exports, '__esModule', { value: true });

})));

一切準備就緒後，我們可以在頁面上呼叫外掛的初始化程式碼，即可完成這個vue tab外掛。

new Vue({
  el:"#app",
});

$('.js-tilt').tilt({

})
