variable Editor

const Editor: ComponentType<EditorProps>;

  • 富文本编辑器，可以对图片、文字进行编辑。

    编辑器导出内容支持带标签的 html和纯文本的 text，编辑器内部采用 delta 格式进行存储。

    通过 setContents 接口设置内容时，解析插入的 html 可能会由于一些非法标签导致解析错误，建议开发者在小程序内使用时通过 delta 进行插入。

    富文本组件内部引入了一些基本的样式使得内容可以正确的展示，开发时可以进行覆盖。需要注意的是，在其它组件或环境中使用富文本组件导出的 html 时，需要额外引入 这段样式，并维护 <ql-container><ql-editor></ql-editor></ql-container> 的结构。

    图片控件仅初始化时设置有效。

    *编辑器内支持部分 HTML 标签和内联样式，不支持 **class** 和 **id*** forms weapp @example_react

const OfficialAccount: ComponentType<OfficialAccountProps>;

    在一个小程序的生命周期内，只有从以下场景进入小程序，才具有展示引导关注公众号组件的能力:

    当小程序从扫小程序码场景（场景值1047，场景值1124）打开时 当小程序从聊天顶部场景（场景值1089）中的「最近使用」内打开时，若小程序之前未被销毁，则该组件保持上一次打开小程序时的状态 当从其他小程序返回小程序（场景值1038）时，若小程序之前未被销毁，则该组件保持上一次打开小程序时的状态 open weapp

variable PageContainer

const PageContainer: ComponentType<PageContainerProps>;

  • 页面容器

    小程序如果在页面内进行复杂的界面设计（如在页面内弹出半屏的弹窗、在页面内加载一个全屏的子页面等），用户进行返回操作会直接离开当前页面，不符合用户预期，预期应为关闭当前弹出的组件。 为此提供“假页”容器组件，效果类似于 popup 弹出层，页面内存在该容器时，当用户进行返回操作，关闭该容器不关闭页面。返回操作包括三种情形，右滑手势、安卓物理返回键和调用 navigateBack 接口。

    Bug & Tip 1. tip: 当前页面最多只有 1 个容器，若已存在容器的情况下，无法增加新的容器 2. tip: wx.navigateBack 无法在页面栈顶调用，此时没有上一级页面 viewContainer weapp, alipay, rn

variable ScrollView

const ScrollView: ComponentType<ScrollViewProps>;

  • 可滚动视图区域。使用竖向滚动时，需要给scroll-view一个固定高度，通过 WXSS 设置 height。组件属性的长度单位默认为 px

    Tips: H5 中 ScrollView 组件是通过一个高度（或宽度）固定的容器内部滚动来实现的，因此务必正确的设置容器的高度。例如: 如果 ScrollView 的高度将 body 撑开，就会同时存在两个滚动条（body 下的滚动条，以及 ScrollView 的滚动条）。 微信小程序 中 ScrollView 组件如果设置 scrollX 横向滚动时，并且子元素为多个时（单个子元素时设置固定宽度则可以正常横向滚动），需要通过 WXSS 设置 white-space: nowrap 来保证元素不换行，并对 ScrollView 内部元素设置 display: inline-block 来使其能够横向滚动。 viewContainer weapp, alipay, swan, tt, qq, jd, h5, rn, harmony @example_react

variable ShareElement

const ShareElement: ComponentType<ShareElementProps>;

  • 共享元素

    共享元素是一种动画形式，类似于 [flutter Hero](https://flutterchina.club/animations/hero-animations/) 动画，表现为元素像是在页面间穿越一样。该组件需与 [PageContainer](/docs/components/viewContainer/page-container) 组件结合使用。 使用时需在当前页放置 ShareElement 组件，同时在 PageContainer 容器中放置对应的 ShareElement 组件，对应关系通过属性值 key 映射。当设置 PageContainer 显示时，transform 属性为 true 的共享元素会产生动画。当前页面容器退出时，会产生返回动画。 skyline weapp, alipay @example_react
