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"), 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="/UploadFiles/2021-04-02/slide_prev_btn.png">总结

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
