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="'+this.data[item].img+'" alt="'+this.data[item].title+'"/>'; unitItem += '<span class="elementOverlay"></span>'; unitItem += '<span class="leftShadow"></span>'; unitItem += '<span class="rightShadow"></span>'; contentHolderUnit.innerHTML = unitItem; this.contentHolder.appendChild(contentHolderUnit); } this.content.appendChild(this.contentHolder); this.parent.append(this.content); this.parent.css({overflow:'hidden'}); this.initContent(); this.bind(); this.start(); }, initContent: function(){ contentHolderUnit = this.parent.find(".contentHolderUnit");

相关vue组件代码以及使用方式:
代码如下:
