##How to write a carousel image in vue.js:

Let’s talk about a simple idea. Use

v-if or v-show for image carousel instead of the original Js sliding, and use transition for transition effect. It can be easily implemented. Note that you can see two pictures during the sliding process, so you need to use two transitions.

(1) First write the overall framework

Render the number of small dots based on the array of imgArray photos, bind on to the span to light up the small dots, photo The display and hiding are displayed through the custom variable ifshow, and nowindex controls the photos corresponding to the carousel.

(2) If the array of carousel images is a local image and is not placed under a static file, please circle the path with require, otherwise the path will report an error. Not required if obtained from the backend server.

data(){
return{
imgArray: [
require('../../img/item_01.png'),
require('../../img/item_02.png'),
require('../../img/item_03.png'),
require('../../img/item_04.png')
]
}
}

(3) The main purpose is to change the status of the carousel image by changing the custom variable nowindex. It should be noted that two images can be seen during the sliding process, so a short timing is set in the goto function. The device allows one to be displayed and the other to be hidden, and different transition effects can be added to each.

Here, this simple carousel image ends.
