||||
<g-preview-img :imgList="imgList" ref="preview"><g-preview-img> |
||||
</template> |
||||
|
||||
<script setup> |
||||
import { ref } from 'vue' |
||||
const preview = ref(null) |
||||
const imgList = ['图片路径1','图片路径2'] |
||||
const handleClick = (idx)=>{ |
||||
// idx为要打开的图片的索引，也可以不传，默认打开第一张 |
||||
// handlePreviewImg的参数支持传入单张图片地址或单个视频地址 |
||||
preview.value.handlePreviewImg(idx) |
||||
} |
||||
</script> |
||||
``` |
||||
|
||||

||||
|
||||
<g-preview-img :imgList="imgList" ref="preview"> |
||||
<template> |
||||
<!--你的翻页按钮--> |
||||
<view @tap.stop="previousImg">上一页</view> |
||||
<view @tap.stop="nextImg">下一页</view> |
||||
</template> |
||||
</g-preview-img> |
||||
|
||||
<script> |
||||
const preview = ref(null) |
||||
//上一页的方法 |
||||
const previousImg = ()=>{ |
||||
preview.value.previousImg() |
||||
} |
||||
//下一页的方法 |
||||
const previousImg = ()=>{ |
||||
preview.value.nextImg() |
||||
} |
||||
</script> |
||||
``` |
||||
|
||||
#### 支持uniapp原生swiper的属性 |
||||
|
||||
插件内部swiper标签上绑定了$attrs,所以在使用时可以传入一些swiper的属性 |
||||
注意：不要传disable-touch这个属性，会有意想不到的错误 |

# 最简洁的模拟图片预览,支持长按事件，多图左右滑动，大图上下滑动查看，支持图片放大，支持覆盖原生组件/原生导航栏/tabbar 支持vue2/vue3/app/小程序/h5 |
||||
|
||||
- 为了解决项目中因一些特殊原因无法使用uni.previewImage，例如App.onShow或者页面的oShow中写了方法。 |
||||
- 如果用uni.previewImage，每次预览图片都会进到onShow的方法里 |
||||
- 可以基本实现官方的预览图片功能，但是体验不如uni.previewImage() |
||||
- 如没有特殊原因，还是推荐官方的uni.previewImage() |
||||
|
||||
## 安装指引 |
||||
|
||||
##1. 在插件市场打开本插件页面，在右侧点击`使用 HBuilderX 导入插件`，选择要导入的项目点击确定 |
||||
|
||||
##2. 使用方法 vue2写法 |
||||
|

##4. 项目示例 (一般返回的数据图片是以逗号或特殊字符分割的字符串，点击时就需要传两个参数，一个是图片数组，一个是当前图片的index) |
||||
## 注意q-previewImage不要写在循环体中，imgs其实就是用来存放当前图片的数组，每次点击每次赋值就行 |
||||
|
||||
