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"),

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
