關於 html 渲染的 Vue.js 指令

Question

我做了這支筆。 使用 Vue.js 的簡單選項卡。

每個選項卡都從此對象獲取它的內容：

var tabs = [
  {
    title: "Pictures",
    content: "Pictures content"
  },
  {
    title: "Music",
    content: "Music content. Wanna see some <a @click.prevent=\"show = 3\">Documents</a> content?"
  },
  {
    title: "Videos",
    content: "Videos content."
  },
    {
    title: "Documents",
    content: "Documents content. Wanna see some <a @click.prevent=\"show = 1\">Music</a> content?"
  },   
];

要呈現每個選項卡內容：

<div v-for="(tab, index) in tabs" v-if="show == index" :key="index" v-html="tab.content"></div>

我一直試圖讓“tab.content”上的那些點擊指令起作用:(我錯過了什么嗎？

提前致謝。

v-html不是 Vue 內容，它只是一個元素的innerHTML 。 您將無法在v-html內容中使用 Vue 指令或組件（！）。

您可以做的是捕獲並處理組件內的原生點擊事件。 transition-group很方便。

 const tabs = [{ title: "Pictures", content: "Pictures content" }, { title: "Music", content: "Music content. Wanna see some <a data-show=\"3\">Documents</a> content?" }, { title: "Videos", content: "Videos content." }, { title: "Documents", content: "Documents content. Wanna see some <a data-show=\"1\">Music</a> content?" }, ]; var vue = new Vue({ el: "#app", data: { show: 0, tabs }, methods: { navigate(event) { const target = event.target; if (target.dataset.show) { event.preventDefault(); this.show = target.dataset.show; } } } });

 .section { padding: 2em 0; } .fade-up-enter-active, .fade-up-leave-active { transition: all 0.3s ease-in-out; } .fade-up-enter, .fade-up-leave-to { height: 0; transform: translateY(30px); opacity: 0; }
