# 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 |
|||
|
|||

|||
import {getRect} from '@/uni_modules/lime-shared/getRect' |
|||
|
|||
// 全量引入 |
|||
// 这种引入方式，会全量打包 |
|||

|||
``` |
|||
|
|||
#### addUnit |
|||

|||
``` |
|||
|
|||
#### 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 |
|||
``` |
|||
|
|||
#### canIUseCanvas2d |

|||
``` |
|||
|
|||
#### isBase64 |
|||

|||
|
|||
#### throttle |
|||

|||
#### debounce |
|||

|||
|
|||
#### range |
|||
- 生成区间数组 |
|||
|
|||

|||
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) |

|||
``` |
|||
|
|||
#### floatAdd |

|||
``` |
|||
|
|||
#### exif |
|||

|||
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 |
|||

|||
}) |
|||
``` |
|||
|
|||
|
|||
#### 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) |
