# lime-qrcode 二维码
- 一款全平台通用的二维码生成插件,支持uniapp/uniappx(web,ios,安卓)
- uvue 需要导入[lime-qrcodegen](https://ext.dcloud.net.cn/plugin?id=15838)
## 使用
- 导入插件后直接使用
- uvue 需要导入**[lime-qrcodegen](https://ext.dcloud.net.cn/plugin?id=15838)**
#### 基础使用
```html
<l-qrcode value="http://lime.qcoon.cn" />
```
#### ICON
- 带 Icon 的二维码
```html
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" icon="/static/logo.png" iconSize="70rpx"></l-qrcode>
```
#### 颜色
- 通过设置 `color` 自定义二维码颜色,通过设置 `bgColor` 自定义背景颜色。
```html
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" color="rgb(82,196,26)"></l-qrcode>
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" color="rgb(22,119,255)" bgColor="rgb(245,245,245)"></l-qrcode>
```
#### 纠错比例
- 通过设置 `errorLevel` 调整不同的容错等级。
```html
<l-qrcode value="img10.360buyimg.com/img/jfs/t1/182127/16/37474/11761/64659c31F0cd84976/21f25b952f03a49a.jpg" size="300rpx" errorLevel="H"></l-qrcode>
```
#### 生成图片
- 1、通过调用插件的`canvasToTempFilePath`方法生成图片。
```html
<image v-if="image" :src="image" style="width: 300rpx;" mode="widthFix"></image>
<l-qrcode ref="qrcodeRef" value="https://limeui.qcoon.cn" size="300rpx" icon="https://img10.360buyimg.com/img/jfs/t1/182127/16/37474/11761/64659c31F0cd84976/21f25b952f03a49a.jpg" iconSize="70rpx"></l-qrcode>
<button @click="onClick">生成图片</button>
```
```js
// vue3
const qrcodeRef = ref(null)
const onClick = () => {
if(!qrcodeRef.value) return
qrcodeRef.value.canvasToTempFilePath({
success(res) {
image.value = res.tempFilePath
console.log('success:::', res)
},
fail(err) {
console.log('err:::', err)
}
})
}
// vue2
const el = this.$refs['qrcodeRef']
el.canvasToTempFilePath({
success:(res)=>{
this.image = res.tempFilePath
},
fail(err) {
console.log('err:::', err)
}
})
// uvue
const el:LQrcodeComponentPublicInstance = this.$refs['qrcodeRef'] as LQrcodeComponentPublicInstance
el.canvasToTempFilePath({
success:(res: TakeSnapshotSuccess)=>{
this.image = res.tempFilePath
},
fail(err: TakeSnapshotFail) {
console.log('err:::', err)
}
})
```
- 2、通过设置`useCanvasToTempFilePath`在`success`事件里接收图片地址
```html
<image v-if="image" :src="image" style="width: 300rpx;" mode="widthFix"></image>
<l-qrcode useCanvasToTempFilePath @success="success" value="https://limeui.qcoon.cn"></l-qrcode>
```
```js
const image = ref(null)
const success = (img) => {
image.value = img
}
```
### 关于vue2的使用方式
- 插件使用了`composition-api`, 如果你希望在vue2中使用请按官方的教程[vue-composition-api](https://uniapp.dcloud.net.cn/tutorial/vue-composition-api.html)配置
- 关键代码是: 在main.js中 在vue2部分加上这一段即可
```js
// main.js vue2
import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'
Vue.use(VueCompositionAPI)
```
另外插件也用到了TS,vue2可能会遇过官方的TS版本过低的问题,找到HX目录下的`compile-typescript`目录
```cmd
// \HBuilderX\plugins\compile-typescript
yarn add typescript -D
- or -
npm install typescript -D
```
### 查看示例
- 导入后直接使用这个标签查看演示效果
```html
// 代码位于 uni_modules/lime-qrcode/compoents/lime-qrcode
<lime-qrcode />
```
### 插件标签
- 默认 l-qrcode 为 component
- 默认 lime-qrcode 为 demo
## API
### Props
| 参数 | 说明 | 类型 | 默认值 |
| --------------------------| ------------------------------------------------------------ | ---------------- | ------------ |
| value | 扫描后的文本 | <em>string</em> | `-` |
| icon | 二维码中图片的地址 | <em>string</em> | `-` |
| size | 二维码大小 | <em>number,string</em> | `160` |
| iconSize | 二维码中图片的大小 | <em>number,string</em> | `40` |
| color | 二维码颜色 | <em>string</em> | `-` |
| bgColor | 二维码背景颜色 | <em>string</em> | `-` |
| errorLevel | 二维码纠错等级 | `'L' | 'M' | 'Q' | 'H' ` | `M` |
| marginSize | 边距码大小,默认为0码点 | <em>number</em> | `0` |
### 常见问题
- icon 是网络地址时,H5和Nvue需要解决跨域问题,小程序需要配置download
## 打赏
如果你觉得本插件,解决了你的问题,赠人玫瑰,手留余香。

# lime-shared 工具库
- 本人插件的几个公共函数
## 引入
```js
// 按需引入
// 这种只会引入相关的方法
import {getRect} from '@/uni_modules/lime-shared/getRect'
// 全量引入
// 这种引入方式,会全量打包
import {getRect} from '@/uni_modules/lime-shared'
```
## Utils
#### getRect
- 返回节点尺寸信息
```js
// 组件内需要传入上下文
// 如果是nvue 则需要在节点上加与id或class同名的ref
getRect('#id',{context: this}).then(res => {})
```
#### addUnit
- 将未带单位的数值添加px,如果有单位则返回原值
```js
addUnit(10)
// 10px
```
#### unitConvert
- 将带有rpx|px的字符转成number,若本身是number则直接返回
```js
unitConvert('10rpx')
// 5 设备不同 返回的值也不同
unitConvert('10px')
// 10
unitConvert(10)
// 10
```
#### canIUseCanvas2d
- 环境是否支持使用 canvas 2d
```js
canIUseCanvas2d()
// 若支持返回 true 否则 false
```
#### getCurrentPage
- 获取当前页
```js
const page = getCurrentPage()
```
#### base64ToPath
- 把base64的图片转成临时路径
```js
base64ToPath(`xxxxx`).then(res => {})
```
#### pathToBase64
- 把图片的临时路径转成base64
```js
pathToBase64(`xxxxx/xxx.png`).then(res => {})
```
#### sleep
- 睡眠,让 async 内部程序等待一定时间后再执行
```js
async next () => {
await sleep(300)
console.log('limeui');
}
```
#### isBase64
- 判断字符串是否为base64
```js
isBase64('xxxxx')
```
#### throttle
- 节流
```js
throttle((nama) => {console.log(nama)}, 200)('limeui');
```
#### debounce
- 防抖
```js
debounce((nama) => {console.log(nama)}, 200)('limeui');
```
#### random
- 返回指定范围的随机数
```js
random(1, 5);
```
#### range
- 生成区间数组
```js
range(0, 5)
// [0,1,2,3,4,5]
```
#### clamp
- 夹在min和max之间的数值,如小于min,返回min, 如大于max,返回max,否侧原值返回
```js
clamp(0, 10, -1)
// 0
clamp(0, 10, 11)
// 10
clamp(0, 10, 9)
// 9
```
#### floatAdd
- 返回两个浮点数相加的结果
```js
floatAdd(0.1, 0.2) // 0.3
```
#### fillZero
- 补零,如果传入的是`个位数`则在前面补0
```js
fillZero(9);
// 09
```
#### exif
- 获取图片exif
- 支持临时路径、base64
```js
uni.chooseImage({
count: 1, //最多可以选择的图片张数
sizeType: "original",
success: (res) => {
exif.getData(res.tempFiles[0], function() {
let tagj = exif.getTag(this, "GPSLongitude");
let Orientation = exif.getTag(this, 'Orientation');
console.log(tagj, Orientation)
})
}
})
```
#### selectComponent
- 获取页面或当前实例的指定组件,会在页面或实例向所有的节点查找(包括子组件或子子组件)
- 仅vue3,vue2没有测试过
```js
// 当前页面
const page = getCurrentPage()
selectComponent('.custom', {context: page}).then(res => {
})
```
#### createAnimation
- 创建动画,与uni.createAnimation使用方法一致,只为了抹平nvue
```html
<view ref="ball" :animation="animationData"></view>
```
```js
const ball = ref(null)
const animation = createAnimation({
transformOrigin: "50% 50%",
duration: 1000,
timingFunction: "ease",
delay: 0
})
animation.scale(2,2).rotate(45).step()
// nvue 无导出数据,这样写只为了平台一致,
// nvue 需要把 ref 传入,其它平台不需要
const animationData = animation.export(ball.value)
```
## composition-api
- 因本人插件需要兼容vue2/vue3,故增加一个vue文件,代替条件编译
- vue2需要在main.js加上这一段
```js
// vue2
import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'
Vue.use(VueCompositionAPI)
```
```js
//使用
import {computed, onMounted, watch, reactive} from '@/uni_modules/lime-shared/vue'
```
## Hooks
#### useIntersectionObserver
- 使用 Intersection Observer 观察元素可见性的钩子函数
```html
<div class="target">
<h1>Hello world</h1>
</div>
```
```js
// options 接口可传的参数,若在插件里context为必传
interface UseIntersectionObserverOptions {
root ?: string; // 观察器的根元素选择器字符串
rootMargin ?: {
top ?: number; // 根元素顶部边距
bottom ?: number; // 根元素底部边距
left ?: number; // 根元素左侧边距
right ?: number; // 根元素右侧边距
}; // 根元素的边距
thresholds ?: any[]; // 交叉比例数组,用于指定何时触发回调函数
context ?: any; // 上下文对象,用于指定观察器的上下文
initialRatio ?: number; // 初始的交叉比例
observeAll ?: boolean; // 是否同时观察所有交叉对象
}
const options: UseIntersectionObserverOptions = {
rootMargin: {top: 44},
context: this
}
const {stop} = useIntersectionObserver('.target', (result) => {
}, options)
```
