html - Vue.js anchor to div within the same component

Question

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?

Answer 1

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:
