r-swiper vue3 version contains no sliding block, fast continuous broadcast mode, which perfectly solves the mobile/PC end carousel needs

This is a vue3 version of the carousel plug-in, which is perfectly adapted to the mobile terminal and the PC terminal.

Some friends may ask, it is already 2023, and there are countless carousel components on the market, who would be stupid enough to build carousel wheels?

Ah this. . .

Doesn't it mean that existence is reasonable?

The reason? There are two main points

1. If the official swiper package is introduced, will it be too big, is it necessary?

2. There are other small-sized vue3 open source components, which can be adapted to most scenarios, and have encountered special needs many times, but have no choice but to change the source code many times

But Please: Don't Repeat Yourself!

That being the case, then I will package a carousel component with powerful functions and exquisite animation effects, which can perfectly adapt to most of the normal business needs (if this component of mine still can’t meet your needs, in the spirit of patience, think more and more for a while. Gas, take a step back from the principle that the more you think, the more you lose, I advise you to find a product alignment immediately... Ah no, contact me immediately, and I will see if I can optimize it).

This plugin contains the forbidden slider mode (noMove attribute), which can realize the blocking sliding effect inside the swiper carousel Silky mode (fast attribute), when switching continuously, there is no mandatory limit on the animation time, the switching speed only depends on your hand speed, Dove ~ enjoy silky smoothness Can be nested, all bugs encountered so far have been changed

The first time I wrote carousel was 17 years ago. I used jQuery, and the code can no longer be found. This time I browsed a lot of swiper open source codes, organized them comprehensively, and made some optimizations. If you feel that it is not smooth or have suggestions for modifying this plugin, please Contact me in time (the contact information is at the bottom), and finally hope you like it!

Kind tips

By default, the bottom indicator, [pc end: two left and right switching buttons] will be displayed, and both the indicator and the button have the effect of clicking the page

It can be hidden according to the value of props

Named slots: If you feel that the style of the left and right buttons and the indicator is not beautiful or you want to write new content, you can use the following slots

  <!-- left and right button switch page up and down -->
  <template #leftBtn>
      ...
  </template>
  <template #rightBtn>
      ...
  </template>

  <!-- indicator -->
  <template #indicator>
      ...
  </template>

  <!-- other slots -->
  <template #all>
      ...
  </template>

noMove explained

Why is there a noMove attribute [default: cs]?

If I want to nest two carousels, the parent carousel will not be affected when the child carousel is switched. At this time, the child carousel must not trigger the parent carousel to slide when sliding

pc side:

1. Slide the top blue hello world! area, the overall parent swiper page will be switched, the effect is as follows

2. Swipe the earth picture, only switch the internal sub-swiper

We only need to add the className attribute "cs" to the inner element

  <img class="cs" src="../2.png" alt="">

Note that if you feel that cs does not meet the requirements, you can choose to change the props attribute

<rSwiper :noMove="yourClassName"></rSwiper>

<!-- This is consistent with noMove parameter passing -->
<img class="yourClassName" src="../2.png" alt="">

<template>
<div class="home-style">
   <rSwiper class="swiper" :autoPlay="false" :indicator="false" ref="swiper" @loadEnd="funLoadEnd" @transitionend=funTransitionend :mobile="true">
     <rSlide>
       <div class="first-cont">
         <div class="can"></div>
         <!-- Note here that the noMove attribute of the child swiper must not be cs [the noMove attribute in the parent swiper, otherwise its own sliding events will also be blocked] -->
         <rSwiper class="child" noMove="nononononono" playTime="2000" :mobile="true" :autoplay="false">
           <rSlide>
             <img class="cs" src="../5.png" alt="">

Mobile terminal: Many platforms such as JD.com/Taobao/Pinduoduo/Dewu have this demand

Swipe the red box part of the left picture, and the overall swiper will switch

Slide the red box part of the right picture, the overall swiper will not switch, but the internal swiper-banner will switch

Or, some internal areas (such as the blue quick list below) need to complete their own scrolling effect

The complete code is as follows

<template>
   <div class="home-style">
     <rSwiper class="swiper" :autoPlay="false" :identifier="false" ref="swiper" @loadEnd="funLoadEnd" @transitionend="funTransitionend " :mobile="true">

         <div class="first-cont">
           <img src="../1.png" alt="">
           <!-- Add noMove attribute cs here -->
           <div class="box cs">
              <div class="can cs">
                <div class="cs" v-for="i in 100" :key="i">{{i}}</div>

</style>

The above situations can be solved by using the current swiper.

fast silky mode

You can try the swiper official website and the carousel pages of JD.com, Taobao, and Dewu. When you swipe quickly, you will feel disconnected Because inside the carousel component, there will be a protection mechanism for a time period. During this time period, you need to wait for the dynamic effect of the carousel event to complete. At this time, if you force the slide, there will be an exception For the fast mode of the plug-in in this article, you only need to set the fast mode of the swiper to immediately open the silky mode

<rSwiper fast></swiper>

At this point, fast sliding can be realized, and the switching time only depends on your hand speed, enjoying silky smoothness

That's all for this issue, thank you for reading.
