<p>我正在学习Vue.js。在我的应用程序中，我创建了一个带有多个复选框和搜索功能的表单。当用户使用Tab键聚焦复选框并按Enter键时，应该选中复选框。</p> <pre class="brush:html;toolbar:false;">&lt;template&gt; &lt;div&gt; &lt;div v-for=&quot;(ingredient, index) in filteredIngredients&quot; :key=&quot;index&quot; class=&quot;list-group-item px-md-4&quot;&gt; &lt;div class=&quot;row px-3&quot;&gt; &lt;div class=&quot;col-auto&quot;&gt; &lt;input v-model=&quot;ingredient.checkbox&quot; class=&quot;form-check-input&quot; type=&quot;checkbox&quot; @focus=&quot;checkFocus&quot; /&gt; &lt;/div&gt; &lt;div class=&quot;col ps-0&quot;&gt; &lt;span class=&quot;mb-2 d-block text-gray-800&quot;&gt; &lt;strong class=&quot;text-black-600&quot;&gt;{{ ingredient.name }}&lt;/strong&gt; &lt;/span&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/template&gt; &lt;script&gt; export default { methods: { methods: { checkFocus(event) { // 这里我能做什么 }, }, }, } &lt;/script&gt; </pre>
