I am interested in learning how to access the index of elements outside of a v-for loop
<template>
<div class="hero-text">
<h4>0{{ index + 1 }}/{{ homePageImageList.length }}</h4>
</div>
<VueSlickCarousel id="rar" v-bind="settings" ref="carousel">
<div v-for="(item, index) in homePageImageList" :key="index" class="hero-image"
:style="{ backgroundImage: 'url(' + item.imageURL + ')' }">
</div>
</VueSlickCarousel>
</template>
If you are using the "vue-slick-carousel", keep in mind that it emits events. For more information, refer to the documentation.
One useful event is the afterChange event, which provides the new index.
In your scenario, you can store this index in the data:
data() {
return {
currentIndex: 0,
}
},
In your template:
<h4>0{{ currentIndex + 1 }}/{{ homePageImageList.length }}</h4>
And within VueSlickCarousel:
<VueSlickCarousel
id="rar"
v-bind="settings"
ref="carousel"
@after-change="currentIndex = $event"
>
<div
v-for="(item, index) in homePageImageList"
:key="index" class="hero-image"
:style="{ backgroundImage: 'url(' + item.imageURL + ')' }"
></div>
</VueSlickCarousel>
Unfortunately, it is not possible to access the index of a loop beyond its boundaries.
One solution suggested by @dahn is to create a local "counter" variable within your data() function in order to make it usable throughout the component.
