更新時(shí)間：2024年01月11日 08:30:07 作者：五月呀

這篇文章主要給大家介紹了關(guān)于前端強(qiáng)大的圖片預(yù)覽組件Viewer.js使用方法的相關(guān)資料,Viewer.js是一款強(qiáng)大的圖片查看器,雖然簡單且易上手,但是卻并不影響其在圖片查看方面的強(qiáng)大功能,同時(shí)這款優(yōu)秀的插件配置操作起來也非常的方便,需要的朋友可以參考下

1、 Viewer.js簡介

Viewer.js 是一款強(qiáng)大的圖片查看器。我們通過Viewer.js 在頁面上添加強(qiáng)大的圖片查看功能，同時(shí)，這款優(yōu)秀的插件配置操作起來也非常的方便。

Viewer.js分為2個(gè)版本，js版本和jquery版本，下載地址分別為

純JS版本：https://github.com/fengyuanchen/viewerjs

jQuery 版本：GitHub - fengyuanchen/jquery-viewer: A jQuery plugin wrapper for Viewer.js.、

網(wǎng)上看到有說jquery版本有bug，最后選用啦js版本，demo截圖大概如下：

2、Viewer.js支持的功能

支持移動(dòng)設(shè)備觸摸事件
支持響應(yīng)式
支持放大/縮小
支持旋轉(zhuǎn)(類似微博的圖片旋轉(zhuǎn))
支持水平/垂直翻轉(zhuǎn)
支持圖片移動(dòng)
支持鍵盤
支持全屏幻燈片模式(可做屏保)
支持縮略圖
支持標(biāo)題顯示
支持多種自定義事件

3、Viewer.js的API

4 使用方法

4.1 引入方式

js，jquery版本,直接文件引入

Javascript版：

<link rel="stylesheet" href="css/viewer.min.css" rel="external nofollow"  rel="external nofollow" > 
<script src="js/viewer.min.js"></script>

jQuery版：

 <link rel="stylesheet" href="css/viewer.min.css" rel="external nofollow"  rel="external nofollow" >
 <script src="js/jquery.min.js"></script> 
 <script src="js/viewer.min.js"></script>

npm，直接install

npm install viewerjs
