## 平台兼容
| H5 | 微信小程序 | 支付宝小程序 | 百度小程序 | 头条小程序 | QQ 小程序 | App |
| --- | ---------- | ------------ | ---------- | ---------- | --------- | --- |
| √ | √ | √ | 未测 | √ | √ | √ |
## 安装
在市场导入**[海报画板](https://ext.dcloud.net.cn/plugin?id=2389)uni_modules**版本的即可,无需`import`
## 代码演示
### 插件demo
- lime-painter 为 demo
- 位于 uni_modules/lime-painter/components/lime-painter
- 导入插件后直接使用可查看demo
```vue
<lime-painter />
```
### 基本用法
- 插件提供 JSON 及 Template 的方式绘制海报
- 参考 css 块状流布局模拟 css schema。
- 另外flex布局还不是成完善请谨慎使用普通的流布局我觉得已经够用了。
#### 方式一 Template
- 提供`l-painter-view``l-painter-text``l-painter-image``l-painter-qrcode`四种类型组件
- 通过 `css` 属性绘制样式,与 style 使用方式保持一致。
```html
<l-painter>
//如果使用Template出现顺序错乱可使用`template` 等所有变量完成再显示
<template v-if="show">
<l-painter-view
css="background: #07c160; height: 120rpx; width: 120rpx; display: inline-block"
></l-painter-view>
<l-painter-view
css="background: #1989fa; height: 120rpx; width: 120rpx; border-top-right-radius: 60rpx; border-bottom-left-radius: 60rpx; display: inline-block; margin: 0 30rpx;"
></l-painter-view>
<l-painter-view
css="background: #ff9d00; height: 120rpx; width: 120rpx; border-radius: 50%; display: inline-block"
></l-painter-view>
<template>
</l-painter>
```
#### 方式二 JSON
- 在 json 里四种类型组件的`type``view``text``image``qrcode`
- 通过 `board` 设置海报所需的 JSON 数据进行绘制或`ref`获取组件实例调用组件内的`render(json)`
- 所有类型的 schema 都具有`css`字段css 的 key 值使用**驼峰**如:`lineHeight`
```html
<l-painter :board="poster"/>
```
```js
data() {
return {
poster: {
css: {
// 根节点若无尺寸,自动获取父级节点
width: '750rpx'
},
views: [
{
css: {
background: "#07c160",
height: "120rpx",
width: "120rpx",
display: "inline-block"
},
type: "view"
},
{
css: {
background: "#1989fa",
height: "120rpx",
width: "120rpx",
borderTopRightRadius: "60rpx",
borderBottomLeftRadius: "60rpx",
display: "inline-block",
margin: "0 30rpx"
},
views: [],
type: "view"
},
{
css: {
background: "#ff9d00",
height: "120rpx",
width: "120rpx",
borderRadius: "50%",
display: "inline-block"
},
views: [],
type: "view"
},
]
}
}
}
```
### View 容器
- 类似于 `div` 可以嵌套承载更多的 view、text、imageqrcode 共同构建一颗完整的节点树
- 在 JSON 里具有 `views` 的数组字段,用于嵌套承载节点。
#### 方式一 Template
```html
<l-painter>
<l-painter-view css="background: #f0f0f0; padding-top: 100rpx;">
<l-painter-view
css="background: #d9d9d9; width: 33.33%; height: 100rpx; display: inline-block"
></l-painter-view>
<l-painter-view
css="background: #bfbfbf; width: 66.66%; height: 100rpx; display: inline-block"
></l-painter-view>
</l-painter-view>
</l-painter>
```
#### 方式二 JSON
```js
{
css: {},
views: [
{
type: 'view',
css: {
background: '#f0f0f0',
paddingTop: '100rpx'
},
views: [
{
type: 'view',
css: {
background: '#d9d9d9',
width: '33.33%',
height: '100rpx',
display: 'inline-block'
}
},
{
type: 'view',
css: {
background: '#bfbfbf',
width: '66.66%',
height: '100rpx',
display: 'inline-block'
}
}
],
}
]
}
```
### Text 文本
- 通过 `text` 属性填写文本内容。
- 支持`\n`换行符
- 支持省略号,使用 css 的`line-clamp`设置行数,当文字内容超过会显示省略号。
- 支持`text-decoration`
#### 方式一 Template
```html
<l-painter>
<l-painter-view css="background: #e0e2db; padding: 30rpx; color: #222a29">
<l-painter-text
text="登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼"
/>
<l-painter-text
text="登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼"
css="text-align:center; padding-top: 20rpx; text-decoration: line-through "
/>
<l-painter-text
text="登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼"
css="text-align:right; padding-top: 20rpx"
/>
<l-painter-text
text="水调歌头\n明月几时有把酒问青天。不知天上宫阙今夕是何年。我欲乘风归去又恐琼楼玉宇高处不胜寒。起舞弄清影何似在人间。"
css="line-clamp: 3; padding-top: 20rpx; background: linear-gradient(,#ff971b 0%, #ff5000 100%); background-clip: text"
/>
</l-painter-view>
</l-painter>
```
#### 方式二 JSON
```js
// 基础用法
{
type: 'text',
text: '登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼',
},
{
type: 'text',
text: '登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼',
css: {
// 设置居中对齐
textAlign: 'center',
// 设置中划线
textDecoration: 'line-through'
}
},
{
type: 'text',
text: '登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼',
css: {
// 设置右对齐
textAlign: 'right',
}
},
{
type: 'text',
text: '登鹳雀楼\n白日依山尽黄河入海流\n欲穷千里目更上一层楼',
css: {
// 设置行数,超出显示省略号
lineClamp: 3,
// 渐变文字
background: 'linear-gradient(,#ff971b 0%, #1989fa 100%)',
backgroundClip: 'text'
}
}
```
### Image 图片
- 通过 `src` 属性填写图片路径。
- 图片路径支持:网络图片,本地 static 里的图片路径,缓存路径,**字节的static目录是写相对路径**
- 通过 `css``object-fit`属性可以设置图片的填充方式,可选值见下方 CSS 表格。
- 通过 `css``object-position`配合 `object-fit` 可以设置图片的对齐方式,类似于`background-position`,详情见下方 CSS 表格。
- 使用网络图片时:小程序需要去公众平台配置 [downloadFile](https://mp.weixin.qq.com/) 域名
- 使用网络图片时:**H5 和 Nvue 需要决跨域问题**
#### 方式一 Template
```html
<l-painter>
<!-- 基础用法 -->
<l-painter-image
src="https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg"
css="width: 200rpx; height: 200rpx"
/>
<!-- 填充方式 -->
<!-- css object-fit 设置 填充方式 见下方表格-->
<l-painter-image
src="https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg"
css="width: 200rpx; height: 200rpx; object-fit: contain; background: #eee"
/>
<!-- css object-position 设置 图片的对齐方式-->
<l-painter-image
src="https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg"
css="width: 200rpx; height: 200rpx; object-fit: contain; object-position: 50% 50%; background: #eee"
/>
</l-painter>
```
#### 方式二 JSON
```js
// 基础用法
{
type: 'image',
src: 'https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg',
css: {
width: '200rpx',
height: '200rpx'
}
},
// 填充方式
// css objectFit 设置 填充方式 见下方表格
{
type: 'image',
src: 'https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg',
css: {
width: '200rpx',
height: '200rpx',
objectFit: 'contain'
}
},
// css objectPosition 设置 图片的对齐方式
{
type: 'image',
src: 'https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg',
css: {
width: '200rpx',
height: '200rpx',
objectFit: 'contain',
objectPosition: '50% 50%'
}
}
```
### Qrcode 二维码
- 通过`text`属性填写需要生成二维码的文本。
- 通过 `css` 里的 `color` 可设置生成码点的颜色。
- 通过 `css` 里的 `background`可设置背景色。
- 通过 `css `里的 `width``height`设置尺寸。
#### 方式一 Template
```html
<l-painter>
<l-painter-qrcode
text="limeui.qcoon.cn"
css="width: 200rpx; height: 200rpx"
/>
</l-painter>
```
#### 方式二 JSON
```js
{
type: 'qrcode',
text: 'limeui.qcoon.cn',
css: {
width: '200rpx',
height: '200rpx',
}
}
```
### 生成图片
- 方式1、通过设置`isCanvasToTempFilePath`自动生成图片并在 `@success` 事件里接收海报临时路径
- 方式2、通过调用内部方法生成图片
```html
<l-painter ref="painter">...code</l-painter>
```
```js
this.$refs.painter.canvasToTempFilePathSync({
fileType: "jpg",
// 如果返回的是base64是无法使用 saveImageToPhotosAlbum需要设置 pathType为url
pathType: 'url',
quality: 1,
success: (res) => {
console.log(res.tempFilePath);
// 非H5 保存到相册
// H5 提示用户长按图另存
uni.saveImageToPhotosAlbum({
filePath: res.tempFilePath,
success: function () {
console.log('save success');
}
});
},
});
```
### 主动调用方式
- 通过获取组件实例内部的`render`函数 传递`JSON`即可
```html
<l-painter ref="painter" />
```
```js
// 渲染
this.$refs.painter.render(jsonSchema);
// 生成图片
this.$refs.painter.canvasToTempFilePathSync({
fileType: "jpg",
// 如果返回的是base64是无法使用 saveImageToPhotosAlbum需要设置 pathType为url
pathType: 'url',
quality: 1,
success: (res) => {
console.log(res.tempFilePath);
// 非H5 保存到相册
uni.saveImageToPhotosAlbum({
filePath: res.tempFilePath,
success: function () {
console.log('save success');
}
});
},
});
```
### H5跨域
- 一般是需要后端或管理OSS资源的大佬处理
- 一般OSS的处理方式:
1、设置来源
```cmd
*
```
2、允许Methods
```html
GET
```
3、允许Headers
```html
access-control-allow-origin:*
```
4、最后如果还是不行,可试下给插件设置`useCORS`
```html
<l-painter useCORS>
```
### 海报示例
- 提供一份示例,只把插件当成生成图片的工具,非必要不要在弹窗里使用。
- 通过设置`isCanvasToTempFilePath`主动生成图片,再由 `@success` 事件接收海报临时路径
- 设置`hidden`隐藏画板。
请注意,示例用到了图片,海报的渲染是包括下载图片的时间,也许在某天图片会失效或访问超级慢,请更换为你的图片再查看,另外如果你是小程序请在使用示例时把**不校验合法域名**勾上!!!!!不然不显示还以为是插件的锅,求求了大佬们!

### Nvue
- 必须为HBX 3.4.11及以上
### 原生小程序
- 插件里的`painter.js`支持在原生小程序中使用
- new Painter 之后在`source`里传入 JSON
- 再调用`render`绘制海报
- 如需生成图片,请查看微信小程序 cavnas 的[canvasToTempFilePath](https://developers.weixin.qq.com/miniprogram/dev/api/canvas/wx.canvasToTempFilePath.html)
```html
<canvas type="2d" id="painter" style="width: 100%"></canvas>
```
```js
import { Painter } from "./painter";
page({
data: {
poster: {
css: {
width: "750rpx",
},
views: [
{
type: "view",
css: {
background: "#d2d4c8",
paddingTop: "100rpx",
},
views: [
{
type: "view",
css: {
background: "#5f7470",
width: "33.33%",
height: "100rpx",
display: "inline-block",
},
},
{
type: "view",
css: {
background: "#889696",
width: "33.33%",
height: "100rpx",
display: "inline-block",
},
},
{
type: "view",
css: {
background: "#b8bdb5",
width: "33.33%",
height: "100rpx",
display: "inline-block",
},
},
],
},
],
},
},
async onLoad() {
const res = await this.getCentext();
const painter = new Painter(res);
// 返回计算布局后的整个内容尺寸
const { width, height } = await painter.source(this.data.poster);
// 得到计算后的尺寸后 可给canvas尺寸赋值达到动态响应效果
// 渲染
await painter.render();
},
// 获取canvas 2d
// 非2d 需要传一个 createImage 方法用于获取图片信息 即把 getImageInfo 的 success 通过 promise resolve 返回
getCentext() {
return new Promise((resolve) => {
wx.createSelectorQuery()
.select(`#painter`)
.node()
.exec((res) => {
let { node: canvas } = res[0];
resolve({
canvas,
context: canvas.getContext("2d"),
width: canvas.width,
height: canvas.height,
// createImage: getImageInfo()
pixelRatio: 2,
});
});
});
},
});
```
### 旧版(1.6.x)更新
- 由于 1.8.x 版放弃了以定位的方式,所以 1.6.x 版更新之后要每个样式都加上`position: absolute`
- 旧版的 `image` mode 模式被放弃,使用`object-fit`
- 旧版的 `isRenderImage` 改成 `is-canvas-to-temp-file-path`
- 旧版的 `maxLines` 改成 `line-clamp`

查看 [功能介绍](https://jin-yufeng.gitee.io/mp-html/#/overview/feature) 了解更多
## 使用方法
- `uni_modules` 方式
1. 点击右上角的 `使用 HBuilder X 导入插件` 按钮直接导入项目或点击 `下载插件 ZIP` 按钮下载插件包并解压到项目的 `uni_modules/mp-html` 目录下
2. 在需要使用页面的 `(n)vue` 文件中添加
```html
<!-- 不需要引入,可直接使用 -->
<mp-html :content="html" />
```
```javascript
export default {
data() {
return {
html: '<div>Hello World!</div>'
}
}
}
```
3. 需要更新版本时在 `HBuilder X` 中右键 `uni_modules/mp-html` 目录选择 `从插件市场更新` 即可
- 源码方式
1. 从 [github](https://github.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 或 [gitee](https://gitee.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 下载源码
插件市场的 **非 uni_modules 版本** 无法更新,不建议从插件市场获取
2. 在需要使用页面的 `(n)vue` 文件中添加
```html
<mp-html :content="html" />
```
```javascript
import mpHtml from '@/components/mp-html/mp-html'
export default {
// HBuilderX 2.5.5+ 可以通过 easycom 自动引入
components: {
mpHtml
},
data() {
return {
html: '<div>Hello World!</div>'
}
}
}
```
- npm 方式
1. 在项目根目录下执行
```bash
npm install mp-html
```
2. 在需要使用页面的 `(n)vue` 文件中添加
```html
<mp-html :content="html" />
```
```javascript
import mpHtml from 'mp-html/dist/uni-app/components/mp-html/mp-html'
export default {
// 不可省略
components: {
mpHtml
},
data() {
return {
html: '<div>Hello World!</div>'
}
}
}
```
3. 需要更新版本时执行以下命令即可
```bash
npm update mp-html
```
使用 *cli* 方式运行的项目,通过 *npm* 方式引入时,需要在 *vue.config.js* 中配置 *transpileDependencies*,详情可见 [#330](https://github.com/jin-yufeng/mp-html/issues/330#issuecomment-913617687)
如果在 **nvue** 中使用还要将 `dist/uni-app/static` 目录下的内容拷贝到项目的 `static` 目录下,否则无法运行

## 插件扩展
除基本功能外,本组件还提供了丰富的扩展,可按照需要选用
| 名称 | 作用 |
|:---:|---|
| audio | 音乐播放器 |

查看 [插件](https://jin-yufeng.gitee.io/mp-html/#/advanced/plugin) 了解更多
## 关于 nvue
`nvue` 使用原生渲染,不支持部分 `css` 样式,为实现和 `html` 相同的效果,组件内部通过 `web-view` 进行渲染,性能上差于原生,根据 `weex` 官方建议,`web` 标签仅应用在非常规的降级场景。因此,如果通过原生的方式(如 `richtext`)能够满足需要,则不建议使用本组件,如果有较多的富文本内容,则可以直接使用 `vue` 页面
由于渲染方式与其他端不同,有以下限制:
1. 不支持 `lazy-load` 属性
2. 视频不支持全屏播放
3. 如果在 `flex-direction: row` 的容器中使用,需要给组件设置宽度或设置 `flex: 1` 占满剩余宽度
纯 `nvue` 模式下,[此问题](https://ask.dcloud.net.cn/question/119678) 修复前,不支持通过 `uni_modules` 引入,需要本地引入(将 [dist/uni-app](https://github.com/jin-yufeng/mp-html/tree/master/dist/uni-app) 中的内容拷贝到项目根目录下)

## 1.1.02022-03-12
* 【重要】`u-picker` 组件新增 `regionDiscern` 方法 智能识别省市区街道地址
如将字符串 `浙江省杭州市西湖区希望路1333弄是啊我庭12号楼1203` 中识别为
```json
{
"province": {
"code": "330000",
"name": "浙江省"
},
"city": {
"code": "330100",
"name": "杭州市"
},
"area": {
"code": "330106",
"name": "西湖区"
},
"address": "龙井路1号",
"formatted_address": "浙江省杭州市西湖区龙井路1号"
}
```
而组件的 `addressDiscern` 方法还可以识别收货信息,如 `张三 13888888888 上海市嘉定区希望路1333弄是啊我庭12号楼1203` 中识别姓名、手机号、地址(支持多种格式)
## 1.0.132022-03-12
* 【优化】部分细节。
## 1.0.122022-03-09
* 【修复】`u-radio-group` 在 vue3 模式下,设置默认值可能会无效的问题。
## 1.0.112022-03-07
* 【优化】部分细节。
## 1.0.102022-03-05
* 【修复】`u-radio` 中的值相等的判断 == 改为 ===
* 【优化】部分注释的错别字。
## 1.0.92022-03-03
* 【修复】`u-parse` 在 vue3模式下编译到app无法正常显示的问题。
## 1.0.82022-02-26
* 【优化】`u-form` 组件新增2个属性 `inputAlign``clearable` 用于统一设置表单内所有 `u-input` 组件的对应属性默认值
* 【优化】更新城市数据源信息
## 1.0.72022-02-25
* 【重要】`u-picker` 组件新增 `addressDiscern` 方法 智能识别收货信息
如在 `张三 13888888888 上海市嘉定区希望路1333弄是啊我庭12号楼1203` 中识别姓名、手机号、地址(支持多种格式)
即使这样的字符串也能识别 `!!!!~~~$张三~~~上海市嘉定区希望路1333弄是啊我庭12号楼1203【【【【13888888888】`
## 1.0.62022-02-24
* 【优化】`u-form-item` 组件的 `prop` 属性支持 a.b 形式
## 1.0.52022-01-11
* 【修复】`u-sticky` 组件 在微信小程序中无法正常吸顶的问题
## 1.0.42021-12-31
* 【优化】`u-dropdown-item` 组件 0和"" 无法区分的问题。
* 【修复】`u-modal` 在Vue3版本中使用了mask-close-able属性无效的问题
## 1.0.32021-12-20
【优化】u-icon在微信小程序下可能会显示null字符串的问题
## 1.0.22021-12-09
* 1、【优化】`u-button` 组件新增 `timerId` 属性
* 之前的效果是所有按钮一定时间内只能点击1次`共用计算时间`导致点击按钮A后无法马上点击按钮B
* 优化的效果是每个按钮一定时间内只能点击1次`分开计算时间`)且支持设置相同的 timerId 来达到指定按钮 `共用计算时间`
## 1.0.12021-11-22
* 修复 u-parse 组件在微信小程序上的显示问题。

* @property {String} label 输入框左边的文字提示
* @property {Boolean} password 是否密码输入方式(用点替换文字)type为text时有效默认false
* @property {Boolean} clearable 是否显示右侧清空内容的图标控件(输入框有内容,且获得焦点时才显示)点击可清空输入框内容默认true
* @property {Number String} label-width label的宽度单位rpx默认130
* @property {String} label-align label的文字对齐方式默认left
* @property {Object} field-style 自定义输入框的样式,对象形式
* @property {Number | String} clear-size 清除图标的大小单位rpx默认30
* @property {String} input-align 输入框内容对齐方式默认left
* @property {Boolean} border-bottom 是否显示field的下边框默认true
* @property {Boolean} border-top 是否显示field的上边框默认false
* @property {String} icon-color 左边通过icon配置的图标的颜色默认#606266
* @property {Boolean} auto-height 是否自动增高输入区域type为textarea时有效默认true
* @property {String Boolean} error-message 显示的错误提示内容如果为空字符串或者false则不显示错误信息
* @property {String} placeholder 输入框的提示文字
* @property {String} placeholder-style placeholder的样式(内联样式,字符串),如"color: #ddd"
* @property {Boolean} focus 是否自动获得焦点默认false
* @property {Boolean} fixed 如果type为textarea且在一个"position:fixed"的区域需要指明为true默认false
* @property {Boolean} disabled 是否不可输入默认false
* @property {Number String} maxlength 最大输入长度,设置为 -1 的时候不限制最大长度默认140
* @property {String} confirm-type 设置键盘右下角按钮的文字仅在type="text"时生效默认done
* @event {Function} input 输入框内容发生变化时触发
* @event {Function} focus 输入框获得焦点时触发
* @event {Function} blur 输入框失去焦点时触发
* @event {Function} confirm 点击完成按钮时触发
* @event {Function} right-icon-click 通过right-icon生成的图标被点击时触发
* @event {Function} click 输入框被点击或者通过right-icon生成的图标被点击时触发这样设计是考虑到传递右边的图标一般都为需要弹出"picker"等操作时的场景,点击倒三角图标,理应发出此事件,见上方说明
* @example <u-field v-model="mobile" label="手机号" required :error-message="errorMessage"></u-field>
