Question

功能性： 我正在尝试设置一个随机图像页面。因此，当用户进入页面时，页面中的图像表始终是随机的。

我做了什么：

首先，我创建了一个图像文件数组var ImageArray=["","","",....]。其次，我创建了一个随机方法var random_BrandIndex = Math.floor(Math.random() * BrandNameArray.length);，最后，我创建了一个for循环，允许图像填充在html体内创建的表。

我附上了您的细读代码：

//Brand Array
var BrandNameArray = ["lib/img/PAGE03/Brands/Ads.png", "lib/img/PAGE03/Brands/AEO.png", "lib/img/PAGE03/Brands/AO.png", "lib/img/PAGE03/Brands/Beauty.png", "lib/img/PAGE03/Brands/Be.png", "lib/img/PAGE03/Brands/DS.png", "lib/img/PAGE03/Brands/Cch.png", "lib/img/PAGE03/Brands/Coton.png", "lib/img/PAGE03/Brands/Dwel.png", "lib/img/PAGE03/Brands/esBr.png", "lib/img/PAGE03/Brands/Et.png", "lib/img/PAGE03/Brands/E.png"];
//To Set random Brand
var random_BrandIndex = Math.floor(Math.random() * BrandNameArray.length);
//Assign Variable to generate random Brands
var Brand = BrandNameArray[random_BrandIndex];

$(function() {
  console.log(Brand);
  //Auto populate into brand container once randomised
  for (i = 0; i < Brand.length; i++) {
    $('#Brand_' + (i + 1)).attr('src', Brand[i]);
    $('#Brand_' + (i + 1)).show();
  }
});

.Container {
  position: absolute;
  top: 300px;
  left: 300px;
  height: 600px;
  width: 1250px;
  overflow-y: scroll;
}
.innerScroll {
  position: relative;
  width: 1250px;
  height: 600px;
  font-size: 25px;
  color: #8d8989 !important;
  overflow: scroll;
}

<div class="Container">
  <div id="list" class="innerScroll">

问题

从退货控制台日志中，只有返回品牌列表时才会返回1个品牌。我想问一下我做错了什么以及如何将每个返回的随机图像附加到div中的容器中？

请帮忙。

Answer 1

在您的代码（var Brand = BrandNameArray[random_BrandIndex];）中，因此Brand是单个字符串而不是数组。

var BrandNameArray = ["lib/img/PAGE03/Brands/Ads.png", "lib/img/PAGE03/Brands/AEO.png", "lib/img/PAGE03/Brands/AO.png", "lib/img/PAGE03/Brands/Beauty.png", "lib/img/PAGE03/Brands/Be.png", "lib/img/PAGE03/Brands/DS.png", "lib/img/PAGE03/Brands/Cch.png", "lib/img/PAGE03/Brands/Coton.png", "lib/img/PAGE03/Brands/Dwel.png", "lib/img/PAGE03/Brands/esBr.png", "lib/img/PAGE03/Brands/Et.png", "lib/img/PAGE03/Brands/E.png"];
//To Set random Brand

$(function() {
  //Auto populate into brand container once randomised
  for (i = 0; i < $('#list').find('img').length; i++) {
var random_BrandIndex = Math.floor(Math.random() * BrandNameArray.length);
//Assign Variable to generate random Brands
var Brand = BrandNameArray[random_BrandIndex];
    $('#Brand_' + (i + 1)).attr('src', Brand);
    $('#Brand_' + (i + 1)).show();
  }
});

随机图像未显示
