一、Univer介绍
Univer 是 Office 系列办公套件的开源替代品,包括电子表格、文档和幻灯片。目前提供公式、数字格式、条件格式、数据验证、图文混排等功能。你可以将 Univer 集成到你的系统当中,并基于 Univer 开发个性化的业务需求。
二、使用步骤
1、使用UMD
<scriptsrc="https://unpkg.com/@univerjs/umd/lib/univer.full.umd.js"></script> <linkrel="stylesheet"href="https://unpkg.com/@univerjs/umd/lib/univer.css">
将上边两个链接复制到浏览器打开,另存为进行下载到本地
引入到publish/index.html中
组件内使用
<template>
<div ref="sheetContainer" style="height: 100%"></div>
</template>
<script setup>
const {
UniverCore,
UniverDesign,
UniverEngineRender,
UniverEngineFormula,
UniverDocs,
UniverDocsUi,
UniverUi,
UniverSheets,
UniverSheetsUi,
UniverSheetsNumfmt,
UniverSheetsFormula,
UniverFacade,
} = window;
const props = defineProps({
data: {
type: Object,
default: () => ({}),
},
});
const univerRef = ref(null);
const workbook = ref(null);
const sheetContainer = ref(null);
const univerAPI = ref(null);
const init = (data) => {
const univer = new UniverCore.Univer({
theme: UniverDesign.defaultTheme,
});
univerRef.value = univer;
univer.registerPlugin(UniverEngineRender.UniverRenderEnginePlugin);
univer.registerPlugin(UniverEngineFormula.UniverFormulaEnginePlugin);
univer.registerPlugin(UniverUi.UniverUIPlugin, {
container: sheetContainer.value,
});
univer.registerPlugin(UniverDocs.UniverDocsPlugin, {
hasScroll: false,
});
univer.registerPlugin(UniverDocsUi.UniverDocsUIPlugin);
univer.registerPlugin(UniverSheets.UniverSheetsPlugin);
univer.registerPlugin(UniverSheetsUi.UniverSheetsUIPlugin);
univer.registerPlugin(UniverSheetsNumfmt.UniverSheetsNumfmtPlugin);
univer.registerPlugin(UniverSheetsFormula.UniverSheetsFormulaPlugin);
workbook.value = univer.createUniverSheet(data);
univerAPI.value = UniverFacade.FUniver.newAPI(univer);
};
onMounted(() => {
init(props.data);
});
const getData = () => {
if (!workbook.value) {
throw new Error('Workbook is not initialized');
}
return workbook.value.save();
};
defineExpose({
getData,
univerAPI: univerAPI.value,
});
</script>
2、npm安装
npm install @univerjs/core @univerjs/design @univerjs/docs @univerjs/docs-ui @univerjs/engine-formula @univerjs/engine-render @univerjs/sheets @univerjs/sheets-formula @univerjs/sheets-ui @univerjs/ui
npm install @univerjs/facade

var { UniverCore } = window;
/**

export const DEFAULT_WORKBOOK_DATA = {

},
'sheet-03': {

cellData: {},
},
},
};
四、API
// 获取当前表数据
const activeSheet = univerAPI.getActiveWorkbook().getActiveSheet()
// 设置单元格 value
const range = activeSheet.getRange(0, 0)
if (!range) {
throw new Error('range is not defined')
}
range.setValue(value)
// 设置某个范围单元格数据
const values = [
['Hello', 'World!'],
['Hello', 'Univer!'],
]
const range = activeSheet.getRange(0, 0, values.length, values[0].length)
// getRange对应的从第0行第0列,到第X行,第X列(索引0开始)
if (!range)
throw new Error('range is not defined')
range.setValues(values)
// 获取某个单元格value =>getRange=>第X行,第X列, 到 到第X行,第X列(索引0开始)
const range = activeSheet.getRange(0, 0, 2, 2)
if (!range)
throw new Error('range is not defined')
const data = []
range.forEach((row, col, cell) => {
data[row] = data[row] || []
data[row][col] = cell.v?.toString()
})
// 获取workbookData 和传入的数据格式一致
const activeWorkbook = univerAPI.getActiveWorkbook()
console.log(JSON.stringify(activeWorkbook.getSnapshot(), null, 2))
// 获取sheetData 数据 -> 是获取workbookData中的sheet中的data
const activeWorkbook = univerAPI.getActiveWorkbook()
if (!activeWorkbook)
throw new Error('activeWorkbook is not defined')
const snapshot = activeWorkbook.getSnapshot()
const sheet1 = Object.values(snapshot.sheets).find((sheet) => {
return sheet.id === 'sheet-01'
})
// 创建sheet
const activeWorkbook = univerAPI.getActiveWorkbook()
const sheet = activeWorkbook.create('Sheet2', 10, 10) // 设置10行10列表格
// scroll to B100
const activeWorkbook = univerAPI.getActiveWorkbook()
univerAPI.executeCommand('sheet.command.scroll-to-cell', {
range: {
// top 设置 0 0
startColumn: 1,
startRow: 99,
},
})
// scroll to bottom
const { rowCount } = activeSheet._worksheet.getSnapshot()
univerAPI.executeCommand('sheet.command.scroll-to-cell', {
range: {
startColumn: 0,
startRow: rowCount - 1,
},
})
// 设置单元格背景
const range = activeSheet.getRange(0, 0, 1, 1)
range?.setBackgroundColor('red')
// 聚焦单元格
const subUnitId = activeSheet._worksheet.getSheetId()
univerAPI.executeCommand('sheet.operation.set-selections', {
selections: [{
range: {
startRow: 0,
startColumn: 0,
endRow: 0,
endColumn: 0,
rangeType: 0,
},
}],
subUnitId,
unitId: activeWorkbook.getId(),
type: 2,
})
// 清除A1 styles
const subUnitId = activeSheet._worksheet.getSheetId()
await univerAPI.executeCommand('sheet.operation.set-selections', {
selections: [{
range: {
startRow: 0,
startColumn: 0,
endRow: 0,
endColumn: 0,
rangeType: 0,
},
}],
subUnitId,
unitId: activeWorkbook.getId(),
type: 2,
})
univerAPI.executeCommand('sheet.command.clear-selection-format')
五、案例应用:univer在线协同表格
使用node.js搭建websorket
后端代码:
//创建一个WebSocket服务器,在8080端口启动
const WebSocket = require('ws');
const server = new WebSocket.Server({ port: 8089 });
// 监听前端连接websocket(ws.on的connection事件)
server.on('connection', function connection(ws, req) {
const ip = req.socket.remoteAddress;
const port = req.socket.remotePort;
const clientName = ip + port;
console.log('%s is connected ', clientName);
});
//只要有WebSocket连接到该服务器,就会触发'connection'事件;req对象可以用来获取客户端的信息,如ip、端口号
//获取所有已连接的客户端信息,则可以使用server.clients数据集
// 服务器接收数据(ws.on的message事件)
module.exports.listener = () => {
server.on('connection', (ws, req) => {
console.log('有客户端连接成功了', ws, req);
// 对客户端的连接对象进行message事件的监听
// 当客户端有消息发送给服务器时,服务器就能够触发该消息
// msg:由客户端发给服务端的数据
ws.on('message', (msg = {}) => {
console.log('客户端发送给服务器端', msg);
// 当接收到客户端传的参数之后服务器端可以执行某些操作(具体看需求)
// 小编这里是做了一个数据返回给客户端
// 是当客户端连接成功之后会发送一条信息告诉服务器,服务器监听到信息之后再返回数据给客户端
// 由服务端往客户端发送数据
server.clients.forEach((client) => {
console.log(client, 'client');
// client.send(JSON.stringify(info));
client.send(msg);
});
});
});
};
前端代码:
<template>
<div>
<div id="univerContainer" style="height: 500px"></div>
</div>
</template>
<script setup>
var {
UniverCore,
UniverDesign,
UniverEngineRender,
UniverEngineFormula,
UniverDocs,
UniverDocsUi,
UniverUi,
UniverSheets,
UniverSheetsUi,
UniverSheetsNumfmt,
UniverSheetsFormula,
UniverFacade,
} = window;
var univer = new UniverCore.Univer({
theme: UniverDesign.defaultTheme,
});
univer.registerPlugin(UniverEngineRender.UniverRenderEnginePlugin);
univer.registerPlugin(UniverEngineFormula.UniverFormulaEnginePlugin);
univer.registerPlugin(UniverUi.UniverUIPlugin, {
container: 'univerContainer',
});
univer.registerPlugin(UniverDocs.UniverDocsPlugin, {
hasScroll: false,
});
univer.registerPlugin(UniverDocsUi.UniverDocsUIPlugin);
univer.registerPlugin(UniverSheets.UniverSheetsPlugin);
univer.registerPlugin(UniverSheetsUi.UniverSheetsUIPlugin);
univer.registerPlugin(UniverSheetsNumfmt.UniverSheetsNumfmtPlugin);
univer.registerPlugin(UniverSheetsFormula.UniverSheetsFormulaPlugin);
univer.createUniverSheet({
id: 'univer-1',
sheets: {
'sheet-01': {
id: 'sheet-01',
name: 'sheet1',
cellData: {},
},
},
});
const univerAPI = UniverFacade.FUniver.newAPI(univer);
const ws = univerAPI.createSocket('ws://localhost:8089');
ws.open$.subscribe(() => {
console.log('websocket opened');
// ws.send('hello')
});
ws.message$.subscribe((message) => {
console.log('websocket message', JSON.parse(message.data));
const content = JSON.parse(message.data);
console.log('content', content);
const { command, options } = content;
const { id, params } = command;
console.log(params, 'params--------');
// 接受到协同数据,本地落盘
univerAPI.executeCommand(id, params, options);
});
ws.close$.subscribe(() => {
console.log('websocket closed');
});
ws.error$.subscribe((error) => {
console.log('websocket error', error);
});
univerAPI.onCommandExecuted((command, options) => {
// 仅同步本地 mutation
if (
command.type !== 2 ||
options?.fromCollab ||
options?.onlyLocal ||
command.id === 'doc.mutation.rich-text-editing'
) {
return;
}
const commandInfo = JSON.stringify({
command,
options: { fromCollab: true },
});
console.log(commandInfo, 'commandInfo');
ws.send(commandInfo);
});
</script>
注意:必须指定id才能协同
univer.createUniverSheet({
id: 'univer-1',
sheets: {
'sheet-01': {
id: 'sheet-01',
name: 'sheet1',
cellData: {},
},
},
});
