The carousel effect source code is implemented with vue
May 30, 2021 Article blog
Vue thought is only available for beginners
1. Principle:
-
v-on:click="prev"v-on is used to bind events -
v-if="条件"v-if to control the existence (display) of a this dom, high performance consumption; -
v-show="条件"v-show to control the display properties of the element -
v-bind:src="#"
vue simply controls the display and hiding of left and right arrows by
v-show="index!=0"
v-show="index<imgArr.length-1"
2. Code (css style code can be designed by itself)
