I am working on scroll to top and bottom button using vuetify.
Currently, i only able to scroll to bottom page. I want it to be able to scroll to the top of the page when the user reaches the bottom of the page and vice-versa.
I try to use v-if and v-else but it seems like it does not work. Any idea on how to implement scroll to top and bottom in one single button ?
ScrollToTopBottom.vue
<template>
<div>
<v-btn v-if = "!isVisible"
v-scroll="onScroll" v-show="isVisible" fab fixed bottom right color="primary" @click="toBottom">
<v-icon>mdi-arrow-down-bold-box-outline</v-icon>
</v-btn>
<v-btn v-else
v-scroll="onScroll" v-show="isVisible" fab fixed bottom right color="primary" @click="toTop">
<v-icon>mdi-arrow-up-bold-box-outline</v-icon>
</v-btn>
</div>
</template>
<script>
export default{
data () {
return {
isVisible: false
}
},
methods: {
onScroll () {
this.isVisible = window.scrollY > 50
},
toTop () {
window.scrollTo({
top: 0,
left: 0,
behavior: 'smooth'
}
)
},
toBottom(){
window.scrollTo({
top: document.body.scrollHeight,
behavior: 'smooth'
})
}
}
}
</script>
Try like following snippet:
Vue.component('scrollToTopButton', {
template: `
<div v-scroll="onScroll">
<v-btn v-if="!isVisible" fab fixed bottom right color="primary" @click="toBottom">
<v-icon>mdi-arrow-down-bold-box-outline</v-icon>
</v-btn>
<v-btn v-else fab fixed bottom right color="primary" @click="toTop">
<v-icon>mdi-arrow-up-bold-box-outline</v-icon>
</v-btn>
</div>
`,
data () {
return {
isVisible: false
}
},
methods: {
onScroll() {
this.isVisible = window.scrollY > 50
},
toTop() {
window.scrollTo({
top: 0,
left: 0,
behavior: 'smooth'
})
},
toBottom(){
window.scrollTo({
top: document.body.scrollHeight,
behavior: 'smooth'
})
}
}
})
