Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

jybvue-img-preview 简介

安装

使用 npm 进行安装

npm install jyb-img-preview

在 main.js 进行全局引入

import jybvueImgPreview from "jyb-img-preview";
Vue.use(jybvueImgPreview);

在组件中进行使用

<img :src="url" @click="previewImg(url)" />
methods: {
	previewImg (url) {
		this.$jybvueImgPreview(url)
	}
}

使用

this.$jybvueImgPreview() 方法可以接收一个字符串类型的 url,或者对象类型的配置,具体使用方法如下

  • 接收一个地址字符串this.$jybvueImgPreview(url)
this.$jybvueImgPreview('https://fuss10.elemecdn.com/8/27/f01c15bb73e1ef3793e64e6b7bbccjpeg.jpeg') // 线上地址
this.$jybvueImgPreview('./img/logo.jpeg') // 本地地址
  • 接收一个对象this.$jybvueImgPreview(options)
# 单图预览
this.$jybvueImgPreview({
    url: 'https://fuss10.elemecdn.com/8/27/f01c15bb73e1ef3793e64e6b7bbccjpeg.jpeg',
})

# 多图预览
this.$jybvueImgPrevieww({
    multiple: true, // 开启多图预览模式
    nowImgIndex: 1, // 多图预览,默认展示第二张图片
    imgList: ['1.png', '2.png', '3.png'], // 需要预览的多图数组
})

配置项

| 字段 | 类型 | 默认值 | 备注 | | -------------- | ------- | ------ | ------------------------------ | | url | String | 无 | 预览的图片地址,多图预览时省略 | | multiple | Boolean | false | 是否多图预览 | | nowImgIndex | Number | 0 | 多图预览时默认显示的图片下标 | | imgList | Array | 无 | 多图预览时传入的图片数组 | | keyboard | Boolean | false | 是否开启键盘控制 | | clickMaskCLose | Boolean | false | 是否可以点击遮罩层关闭 | | controlBar | Boolean | true | 是否显示控制条及页码 | | closeBtn | Boolean | true | 是否显示关闭按钮 | | arrowBtn | Boolean | true | 是否显示左右翻页按钮 |

全局配置

对于某些配置,例如开启键盘事件,点击遮罩层关闭,我们可能要全局保持统一,但却需要在每一次调用时重复配置,为了解决这个问题,我们提供了全局配置项,您可以在引入插件的时候,将全局配置项作为第二个参数传入即可,以免再每次调用的时候重复配置。

// main.js
import jybvueImgPreview from 'jyb-img-preview'
Vue.use(jybvueImgPreview, {
  keyboard: true,
  clickMaskCLose: true
  ...
})

如开启键盘控制事件后,相对应功能控制按键如下

| 按键 | 功能 | | ---- | ------------ | | w | 放大 | | s | 缩小 | | a | 上一张 | | d | 下一张 | | q | 逆时针旋转 | | e | 顺时针旋转 | | r | 图片复位 | | esc | 关闭图片预览 |

如不考虑兼容性问题,上述的背景颜色均可接收渐变色
