Adding Responsive Bootstrap Carousel in Vue.js
We are all set with basic configuration now we will learn to implement Image Slider or bootstrap carousel in Vue.js. Open your vue template and add the following code.
<template>
<div>
<b-carousel
id="carousel-1"
v-model="slide"
:interval="3000"
controls
indicators
background="#ccc"
img-width="1024"
img-height="480"
style="text-shadow: 1px 1px 2px #000;"
@sliding-start="onSlideStart"
@sliding-end="onSlideEnd"
>
<!-- Text slides with image -->
<b-carousel-slide
caption="First slide"
text="Nulla vitae elit libero, a pharetra augue mollis interdum."
img-src="https://picsum.photos/1024/480/?image=52"
></b-carousel-slide>
<!-- Slides with custom text -->
<b-carousel-slide img-src="https://picsum.photos/1024/480/?image=54">
<h1>Hello world!</h1>
</b-carousel-slide>
<!-- Slides with image only -->
<b-carousel-slide img-src="https://picsum.photos/1024/480/?image=58"></b-carousel-slide>
<!-- Slides with img slot -->
<!-- Note the classes .d-block and .img-fluid to prevent browser default image alignment -->
<b-carousel-slide>
<template v-slot:img>
<img
class="d-block img-fluid w-100"
width="1024"
height="480"
src="https://picsum.photos/1024/480/?image=55"
alt="image slot"
>
</template>
</b-carousel-slide>
<!-- Slide with blank fluid image to maintain slide aspect ratio -->
<b-carousel-slide caption="Blank Image" img-blank img-alt="Blank image">
<p>
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse eros felis, tincidunt
a tincidunt eget, convallis vel est. Ut pellentesque ut lacus vel interdum.
</p>
</b-carousel-slide>
</b-carousel>
<p class="mt-4">
Slide #: {{ slide }}<br>
Sliding: {{ sliding }}
</p>
</div>
</template>
<script>
export default {
data() {
return {
slide: 0,
sliding: null
}
},
methods: {
onSlideStart() {
this.sliding = true
},
onSlideEnd() {
this.sliding = false
}
}
}
</script>Let us understand carousel props.
We set the sliding-start event, and this event works when the image slider is triggered. The sliding-end event emits when transitioning to a new slide ends.
The carousel can be styled using style prop, and we can even manage the carousel or image slider’s width and height using img-width and img-height properties.
To set the delay duration between sides use. the interval prop in milliseconds.
We can activate the previous and next controls using controls prop.
The indicators prop enable the indicator buttons for directly going to particular slide.
Adding Animation in Carousel
By default, bootstrap carousel comes with a sliding animation. However, we can change the image slider animation to cross-fade animation, and it can be done by just adding fade property in b-carousel component.
<template>
<div>
<b-carousel
id="carousel-1"
fade
v-model="slide"
:interval="4000"
controls
indicators
background="#ababab"
img-width="1024"
img-height="480"
style="text-shadow: 1px 1px 2px #333;"
@sliding-start="onSlideStart"
@sliding-end="onSlideEnd"
>
<!-- Text slides with image -->
<b-carousel-slide
caption="First slide"
text="Nulla vitae elit libero, a pharetra augue mollis interdum."
img-src="https://picsum.photos/1024/480/?image=52"
></b-carousel-slide>
<!-- Slides with custom text -->
<b-carousel-slide img-src="https://picsum.photos/1024/480/?image=54">
<h1>Hello world!</h1>
</b-carousel-slide>
<!-- Slides with image only -->
<b-carousel-slide img-src="https://picsum.photos/1024/480/?image=58"></b-carousel-slide>
<!-- Slides with img slot -->
<!-- Note the classes .d-block and .img-fluid to prevent browser default image alignment -->
<b-carousel-slide>
<template v-slot:img>
<img
class="d-block img-fluid w-100"
width="1024"
height="480"
src="https://picsum.photos/1024/480/?image=55"
alt="image slot"
>
</template>
</b-carousel-slide>
<!-- Slide with blank fluid image to maintain slide aspect ratio -->
<b-carousel-slide caption="Blank Image" img-blank img-alt="Blank image">
<p>
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse eros felis, tincidunt
a tincidunt eget, convallis vel est. Ut pellentesque ut lacus vel interdum.
</p>
</b-carousel-slide>
</b-carousel>
<p class="mt-4">
Slide #: {{ slide }}<br>
Sliding: {{ sliding }}
</p>
</div>
</template>
<script>
export default {
data() {
return {
slide: 0,
sliding: null
}
},
methods: {
onSlideStart() {
this.sliding = true
},
onSlideEnd() {
this.sliding = false
}
}
}
</script>How to Disable Animation?
Disabling animation is very easy with bootstrap-vue plugin. Add no-animation prop in b-carousel component to disable slide animation.
<template>
<b-carousel
id="carousel-1"
no-animation
v-model="slide"
:interval="3000"
background="#ababab"
img-width="1024"
img-height="480"
style="text-shadow: 1px 1px 2px #333;"
@sliding-start="onSlideStart"
@sliding-end="onSlideEnd">
</b-carousel>
</template>
