Vue.js 锚定到同一组件内的 div [英] Vue.js anchor to div within the same component

问题描述

我正在开发 Vue.js 应用程序，但无法将锚点链接到组件内的某个 div.

我有以下锚点:

葡萄牙波尔图</a>

以及以下 div:

我在哈希模式下使用 vue-router.

问题是，每当我单击porto-button"时，它都会将我重定向到主页"页面('/')

我使用的是 Vue.js 1.X，我尝试使用历史模式(不带 hashbang 的 URL)，但它在刷新页面时给我一个 cannot GET '/page' 错误.

我做错了吗?我该怎么办?

解决方案

因为你在散列模式下使用路由器，你将无法轻松滚动，因为滚动到 /#something 实际上会将您重定向到某事"页面.

你必须自己模拟滚动行为，尝试做这样的事情:

//P.S.代码是为 Vue 2 编写的.//您必须将其调整为 Vue 1.//你的观点:<a class="porto-button" @click="scrollMeTo('porto')">葡萄牙波尔图</a>...<div ref="porto" class="fl-porto">

//您的代码:方法: {scrollMeTo(refName) {var element = this.$refs[refName];var top = element.offsetTop;window.scrollTo(0, top);}}

工作原理:

1. 通过 ref 属性将引用设置为要滚动到的元素；
2. 编写一个函数，以编程方式将 window.scrollY 设置为引用元素的 top.
3. 工作完成了:)

更新 2:

似乎在 Vue 1 ref="name" 看起来像 el:name (docs)，这是一个更新的例子:

I'm developing a Vue.js application and I'm having trouble to link an anchor to a certain div within a component.

I have the following anchor:

<a href="#porto" class="porto-button">Porto, Portugal</a>

and the following div:

<div id="porto" class="fl-porto">

I'm using vue-router in hash mode.

The problem is, whenever I click the "porto-button" it will redirect me to the "home" page ( ' / ' )

I'm using Vue.js 1.X and I tried using history mode (URL without the hashbang) but it gives me a cannot GET '/page' error upon refreshing a page.

Am I doing something wrong? What can I do about this?

解决方案

Because you are using router in hash mode, you will not be able to scroll that easily because scrolling to /#something will actually redirect you to 'something' page.

You will have to emulate scrolling behaviour on your own, try doing something like that:

//P.S. the code is written for Vue 2.
//You will have to adjust it to Vue 1.

//Your view:
<a class="porto-button" @click="scrollMeTo('porto')">Porto, Portugal</a>
...
<div ref="porto" class="fl-porto">

//Your code:
methods: {
  scrollMeTo(refName) {
    var element = this.$refs[refName];
    var top = element.offsetTop;

    window.scrollTo(0, top);
  }
}

How it works:

1. Set the references through ref attribute to the element you would like to scroll to;
2. Write a function that will programmatically set window.scrollY to the top of the referenced element.
3. Job is done :)

Update 2:

Seems that in Vue 1 ref="name" looked like el:name (docs), here is an updated example:
