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";

   window.postercarousel = postercarousel;})(jQuery)

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"),      img: 'http://occe.ospc.cn/upload/2016-01-18/145309107223576.jpg',      // url: "http://www.htmleaf.com/"     },     {      // img: require("../assets/liaojiewaibao.png"),      img: "http://occe.ospc.cn/upload/2016-01-17/145302166917282.jpg",      // url: "http://www.htmleaf.com/"     },     {      img: require("../assets/ruhui.png"),      img: "http://occe.ospc.cn/upload/2016-01-17/14530216405007.png",      // url: "http://www.htmleaf.com/"     },     {      // img: require("../assets/callme.png"),      img: "http://occe.ospc.cn/upload/2016-01-18/145309108911041.jpg",      // url: "http://www.htmleaf.com/"     },    ]   );  } }};</script><style lang="scss">.broadcast { /* postercarousel */ #postercarousel {  width: 100% !important;  height: 450px; } .postercarousel {  position: relative;  height: 100%;  width: 100% !important; } .postercarousel img {  max-width: 100%;  max-height: 100%;  border: 0 none;  background: #888;  display: block; } .postercarousel .contentHolder {  position: relative;  overflow: hidden; } .postercarousel .contentHolderUnit {  cursor: pointer;  position: absolute;  width: 83% !important;  height: 450px; } .postercarousel .contentHolderUnit a.elementLink {  display: block;  overflow: hidden;  z-index: 3;  position: absolute;  left: 0;  right: 0;  width: 100%;  height: 100%; } .postercarousel .contentHolderUnit img {  width: 100%;  height: 100%;  display: block; } .postercarousel .contentHolderUnit .elementTitle { } .postercarousel .contentHolderUnit .elementOverlay {  z-index: 1;  position: absolute;  top: 0;  left: 0;  background: #000;  width: 100%;  height: 100%;  opacity: 0;  filter: opacity=0; } .postercarousel .contentHolderUnit .leftShadow {  position: absolute;  top: 23px;  left:-250px;  // width: 250px;  height:327px;  background: url("../assets/images/leftShadow.png") no-repeat;  background-size: contain; } .postercarousel .contentHolderUnit .rightShadow {  position: absolute;  top: 23px;  right:134px;  height: 327px;  background: url("../assets/images/rightShadow.png") no-repeat;  background-size: contain; } .postercarousel .bannerControls { } .postercarousel .leftNav, .postercarousel .rightNav {  cursor: pointer;  z-index: 10;  position: absolute;  top: 60%;  width: 45px;  height: 45px;  margin-top: -43px; } .postercarousel .leftNav {  left: 7px;  background: url("../assets/images/1.png") no-repeat;  _background: none;  _filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="@/assets/images/slide_prev_btn.png"); } .postercarousel .rightNav {  right: 7px;  background: url("../assets/images/2.png") no-repeat;  _background: none;  _filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="@/assets/images/slide_next_btn.png"); } .postercarousel .leftNav:hover { } .postercarousel .rightNav:hover { } .postercarousel .bottomNav {  z-index: 140;  position: absolute;  width: 100%;  height: 10px;  margin-top: 400px;  padding: 10px 0 0;  text-align: center; } .postercarousel .bottomNavButtonOFF {  cursor: pointer;  overflow: hidden;  display: inline-block;  *display: inline;  *zoom: 1;  width: 10px;  height: 10px;  margin: 0 5px;  vertical-align: top;  -webkit-border-radius: 5px;  -moz-border-radius: 5px;  border-radius: 5px;  background: #c3c3c3; } .postercarousel .bottomNavButtonOFF:hover {  background: #aaa; } .postercarousel .bottomNavButtonON, .postercarousel .bottomNavButtonON:hover {  background: #69aaec; } .postercarousel .bottomNavLeft { } .postercarousel .bottomNavRight { }}</style>
