vue.js层叠轮播

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：

  1 (function(jq){
  2         function postercarousel(o, options, data){
  3         this.parent = jq("#"+ o);
  4         this.body   = jq("body");
  5         if (this.parent.length <= 0) { 
  6             return false;
  7         }
  8         
  9         this.options = jq.extend({}, postercarousel.options, options);
 10         if(typeof(data) !== 'object') return false;
 11 
 12         this.data = data || {};
 13         this.reset();
 14         //处理页面resize
 15         var _this = this;
 16         jq(window).resize(function(){
 17                 _this.reset();
 18         });
 19     };
 20     postercarousel.prototype = {
 21         reset: function(options){
 22             if(typeof(options) == 'object'){
 23                 jq.extend(this.options, options);    
 24             }
 25             if(parseInt(this.body.outerWidth())>1255 || navigator.userAgent.indexOf('iPad') !== -1){
 26                 this.options.width = 970;    
 27             }else{
 28                 this.options.width = 970;    
 29             }
 30             this.total = this.data.length;
 31             this.pageNow = this.options.initPage;
 32             this.preLeft = 0;
 33             this.nextLeft = this.options.width-530;
 34             this.preNLeft = -530;
 35             this.nextNLeft = this.options.width;
 36             this.pageNowLeft = (this.options.width-640)/2
 37             this.drawContent();
 38         },
 39         drawContent: function(){
 40             this.parent.empty();
