vue.js层叠轮播效果的实例代码

最近写公司项目有涉及到轮播banner,一般的ui框架无法满足产品需求;所以自己写了一个层叠式轮播组件;现在分享给大家;

主要技术栈是vue.js ;javascript;jquery;确定实现思路因工作繁忙,暂时不做梳理了;直接贴代码参考;

此组件是基于jquer封装,在vue项目中使用首先需要先安装jquery插件:指令:npm install jquery,安装完成之后再webpack.base.conf.js配置插件:

 plugins: [
  new webpack.ProvidePlugin({
   $: 'jquery',
   jQuery: 'jquery'
  }),
 ]

主要实现逻辑js文件:postercarousel.js;

代码如下:

(function(jq){
    function postercarousel(o, options, data){
    this.parent = jq("#"+ o);
    this.body  = jq("body");
    if (this.parent.length <= 0) { 
      return false;
    }
    
    this.options = jq.extend({}, postercarousel.options, options);
    if(typeof(data) !== 'object') return false;

    this.data = data || {};
    this.reset();
    //处理页面resize
    var _this = this;
    jq(window).resize(function(){
        _this.reset();
    });
  };
  postercarousel.prototype = {
    reset: function(options){
      if(typeof(options) == 'object'){
        jq.extend(this.options, options);  
      }
      if(parseInt(this.body.outerWidth())>1255 || navigator.userAgent.indexOf('iPad') !== -1){
        this.options.width = 970;  
      }else{
        this.options.width = 970;  
      }
      this.total = this.data.length;
      this.pageNow = this.options.initPage;
      this.preLeft = 0;
      this.nextLeft = this.options.width-530;
      this.preNLeft = -530;
      this.nextNLeft = this.options.width;
      this.pageNowLeft = (this.options.width-640)/2
      this.drawContent();
    },
    drawContent: function(){
      this.parent.empty();
      this.parent.css({width:this.options.width+"px", height:this.options.height+"px", position: "relative"});
      this.content = document.createElement("DIV");
      this.content.className = this.options.className;
      this.content.cssText = "width:"+this.options.width+"px;height:"+this.options.height+"px;cursor:move;position:absolute;";
        this.bottomNav = document.createElement("DIV");
        this.bottomNav.className = "bottomNav";
        for(var i=1; i<= this.total; i++){
          var bottomItem = document.createElement("DIV");
          bottomItem.className = "bottomNavButtonOFF";
          if(i == this.pageNow){
            bottomItem.className = "bottomNavButtonOFF bottomNavButtonON";
          }
          bottomItem.setAttribute("ref", i);
          this.bottomNav.appendChild(bottomItem);
        }
        this.content.appendChild(this.bottomNav);
        this.bannerControls = '<div class="bannerControls"> <div class="leftNav" style="display: block;"></div> <div class="rightNav" style="display: block;"></div> </div>';
        this.content.innerHTML += this.bannerControls;

      this.contentHolder = document.createElement("DIV");
      this.contentHolder.style.width = this.options.width + 'px';
      this.contentHolder.style.height = this.options.height + 'px';
      
      for(var item=0, i = 1, l= this.data.length ; item < l ; ++item, ++i){
        var contentHolderUnit = document.createElement("DIV");
        contentHolderUnit.className = "contentHolderUnit";
        contentHolderUnit.setAttribute("ref", i);
        contentHolderUnit.setAttribute("id", 'contentHolderUnit' + (i));
        var unitItem = '<a href="'+this.data[item].url+'" rel="external nofollow" target="_blank" class="elementLink">';
        unitItem += '</a>';
        unitItem += '<img src="/UploadFiles/2021-04-02/'+this.data[item].img+'">

相关vue组件代码以及使用方式:

代码如下:

<template>
 <div class="broadcast">
  <div class="htmleaf-container">
   <div class="htmleaf-content">
    <div id="postercarousel" style="margin:40px auto 0 auto;"></div>
   </div>
  </div>
 </div>
</template>
<script>
import "jQuery";
import "@/static/js/postercarousel";
export default {
 data() {
  return {};
 },
 mounted() {
  this.initposter();
  console.log(postercarousel);
  21  },
 methods: {
  initposter() {
   var postercarousel = new postercarousel(
    "postercarousel",
    { className: "postercarousel" },
    [
     {
      // img: require("../assets/callme.png"),
