使用 jQuery 自定义动态幻灯片答案

【问题标题】：Custom dynamical slideshow with jQuery使用 jQuery 自定义动态幻灯片
【发布时间】：2018-09-25 18:44:21
【问题描述】：

我正在尝试主要使用jQuery 从头开始制作自己的幻灯片。我遇到的问题是当我尝试将其用于手机和平板电脑（通常较小的屏幕）时。所以我的第一个想法就是将所有px 更改为%，但这并没有那么好，我不知道如何以“最佳”方式解决这个问题。

这就是“正常”的样子调整窗口大小时会出现问题，然后我在图像上看到这个黑条。我的目标是整个盒子应该调整大小并看起来像上面的那个。（这是使用谷歌浏览器的移动预览截图）

你可以测试下面的sn-p，它直接显示一个黑条，因为窗口很小。 #AutoSlider{min-height: 400px;} 只是为了不达到 10 px 的高度。

var options = {
Image: {
        Width: "100%",
        Height: "80%",
        BackgroundColor: "black",
        SecPerSlide: "5000"
    },
    ThumbnailContainer: {
        Width: "15%",
        Height: "100%",
        RowColor: "black"
    },
    ThumbnailCell: {
        BackgroundColor: "black",
        Space: "3px",
        Width: "100%",
        Height: "15%",
        FadedEdge: "15%"
    }
}

carsGallery = [];
var container = $("#AutoSlider");
var thumbnailContainer;
var thumbnailCell;
var activeImage;
var autoCount = 1;
var stopSlider = false;
var subImageSliderPage = 0;

$(document).ready(function () {

    startSlider();

【问题讨论】：

很高兴为您提供帮助.. 当您接受时，我正在输入评论.. :) .. 如果您将图像设置为背景，您可以将背景大小设置为封面或包含，但是它可能会歪曲外观..滑块上的好工作:)
@RachelGallen 你的帮助为我节省了很多时间，谢谢！ :) 我主要做后端，但喜欢在有时间的时候做一些 js
节省时间总是好的。时间很宝贵！谢谢你的称赞。继续努力????

【解决方案1】：

我在您的图像选项中添加了一个 VerticalAlign:"top"，并且像素显示在中间垂直对齐（如添加的那样）。我将容器的背景颜色调整为灰色，将 AutoSlider 的高度调整为 320，你当然可以调整回来，我只是为了测试目的而减少了这些..

希望对你有帮助
