文字大小

把选中的文字改成某个大小档位。如果选中了范围,该档位应用到该范围;如果只有光标,则改变当前段落的文字大小。保存的数据只保留允许的档位,不保留 px 这样的任意值。

安装
npm install nabi-note
代码
import {
  createNabiWith, mountSurface, mountToolbar, mountContextToolbar,
  mountHints, watchSettle, boldWing, italicWing, underlineWing,
  strikeWing, typefaceWing, fontSizeWing, clearFormatWing,
  mountViewTools,
} from 'nabi-note'

const selected = [
  boldWing,
  italicWing,
  underlineWing,
  strikeWing,
  typefaceWing,
  fontSizeWing,
  clearFormatWing,
]
const { nabi, registry } = createNabiWith(selected)

const root = document.querySelector('.nabi')!
const content = document.querySelector('.nabi-content')!

// The locale also sets the direction — Arabic and Urdu run right to left
mountSurface({ nabi, registry, root: content, locale: 'zh' })

const settle = watchSettle(document, { surface: content })
const shared = { nabi, registry, surface: content, settle, locale: 'zh' }
const toolbar = mountToolbar({ ...shared, root: document.querySelector('#toolbar')! })
const context = mountContextToolbar({ ...shared, root: document.querySelector('#context')! })
mountHints({ toolbar, context, root, surface: content })
// The preview and fullscreen buttons — they stand their own box at the end of the row
mountViewTools({ ...shared, root, container: document.querySelector('#toolbar')! })

// on every change — hook up your own code here
// nabi.onChange(() => user_callback(nabi.getHtml()))
ts
const selected = wings().use('fs', {
  values: ['sm', 'lg', 'xl'],
}).build()

如果省略 values,会使用 xssmlgxl 档位。若缩小列表,旧文档中已有的其他档位会在加载时被移除。

CSS 样式

可以通过 .nabi-content [data-nabi-size="xs"] 这样的保存档位选择器改变大小。不要编造文档中不存在的任意档位;只在注册的 values 范围内调整 CSS。

css
.article-body [data-nabi-size="xs"] { font-size: .78em; }
.article-body [data-nabi-size="sm"] { font-size: .9em; }
.article-body [data-nabi-size="lg"] { font-size: 1.3em; }
.article-body [data-nabi-size="xl"] { font-size: 1.65em; }

保持各档位之间的大小差距一致,可以在发布文档时保留作者在编辑器中选择的意义。
