SpreadJSでは、JavaScriptライブラリの1つであるVue.jsがサポートされます。Vue.jsは、開発者に複雑なユーザーインターフェイスおよびWebアプリケーションを構築するためにツールを提供します。
SpreadJSでは、次の2つの方法でVue.jsを使用できます。
次の手順を実行します。
Composition API を使用してアプリケーションを作成するには、次の手順を実行します。
Vueアプリを作成する
コマンドプロンプトウィンドウを開き、次のコマンドを入力します。
npm init vue@latest // プロジェクト名に「sjs-vue-app」を指定します
cd sjs-vue-app
コマンドを実行すると、ディレクトリ内の指定の場所にVue.jsプロジェクトが作成されます。Vue.jsプロジェクトの作成方法については、https://ja.vuejs.org/guide/quick-start.html を参照してください。
SpreadJS Vueモジュールをインストールする
次のコマンドを使用して、SpreadJS Vue モジュールをプロジェクトにインストールします。
npm install @grapecity/spread-sheets@xx.x.x
npm install @grapecity/spread-sheets-vue@xx.x.x
npm install @grapecity/spread-sheets-resources-ja@xx.x.x
type=warning
'xx.x.x'の部分には製品のバージョンを指定してください。バージョンの指定を省略すると最新バージョンがインストールされますが、日本語版での動作保証は日本語版サイトで公開しているバージョンのみとなります。
Vue.jsアプリでSpreadJSを使用する
次のサンプルコードを使用して、main.jsファイルを編集します。
import { createApp } from 'vue'
import App from './App.vue'
import { GcSpreadSheets, GcWorksheet, GcColumn } from '@grapecity/spread-sheets-vue';
let app = createApp(App);
app.component('gc-spread-sheets', GcSpreadSheets);
app.component('gc-worksheet', GcWorksheet);
app.component('gc-column', GcColumn);
app.mount('#app')
次のサンプルコードを使用して、App.vueファイルを編集します。
<template>
<div>
<gc-spread-sheets
:hostClass="hostClass"
@workbookInitialized="initWorkbook">
</gc-spread-sheets>
</div>
</template>
<script setup>
import "@grapecity/spread-sheets/styles/gc.spread.sheets.excel2016colorful.css";
import * as GC from "@grapecity/spread-sheets";
import "@grapecity/spread-sheets-vue";
import "@grapecity/spread-sheets-resources-ja";
// 日本語カルチャを設定します
GC.Spread.Common.CultureManager.culture('ja-jp');
const hostClass = "spread-host";
function initWorkbook(spread) {
let sheet = spread.getActiveSheet();
sheet.setValue(0, 0, "Hello");
}
</script>
<style>
.spread-host {
width: 100%;
height: 600px;
}
</style>
アプリケーションを保存して実行する
npm run dev
Vue.jsプロジェクトを作成する
コマンドプロンプトウィンドウを開き、次のコマンドを入力します。
npm install -g @vue/cli
vue create sjs-vue-app // ここでVue 2を選択します
cd sjs-vue-app
コマンドを実行すると、ディレクトリ内の指定の場所にVue.jsプロジェクトが作成されます。
Spread.Sheets Vue.jsモジュールをインストールする
Spread.Sheets Vue.jsモジュール、および日本語リソースを、npmからインストールします。
npm install @grapecity/spread-sheets
npm install @grapecity/spread-sheets-vue
npm install @grapecity/spread-sheets-resources-ja
Vue.jsアプリでSpread.Sheetsを使用する
必要に応じてApp.vueファイルを編集します。ブラウザウィンドウを更新すると、変更が反映されます。例として、次のサンプルコードを使用します。
<template>
<div>
<gc-spread-sheets :hostClass='hostClass'>
<gc-worksheet
:dataSource="dataTable"
:autoGenerateColumns = 'autoGenerateColumns'
>
<gc-column
:width="width"
:dataField="'price'"
:visible = 'visible'
:formatter = 'formatter'
:resizable = 'resizable'
></gc-column>
</gc-worksheet>
</gc-spread-sheets>
</div>
</template>
<script>
import '@grapecity/spread-sheets/styles/gc.spread.sheets.excel2016colorful.css'
import '@grapecity/spread-sheets-vue'
import '@grapecity/spread-sheets-resources-ja';
import * as GC from "@grapecity/spread-sheets";
// カルチャ設定
GC.Spread.Common.CultureManager.culture('ja-jp');
export default {
data(){
return {
hostClass:'spread-host',
autoGenerateColumns:true,
width:300,
visible:true,
resizable:true,
formatter:"$ #.00"
}
},
computed:{
dataTable(){
let dataTable = [];
for (let i = 0; i < 42; i++) {
dataTable.push({price: i + 0.56})
}
return dataTable
}
}
}
</script>
<style scoped>
.spread-host {
width: 500px;
height: 600px;
}
</style>
アプリケーションを保存して実行する
npm run serve
SpreadJSでは、従来のHTMLを使用してVue2を使用できます。この方法には、次の手順があります。
HTMLページを作成する
最初の手順として、HTMLページを作成します。
HTMLテンプレートにSpread.SheetsおよびVue-Spread.Sheetsを追加する
gc.spread.sheets.all...*.min.js 、 gc.SpreadJS...*.css および gc.spread.sheets.vue...*.js ファイルへの参照を、HTMLテンプレート(index.htmlファイル)に追加します。
VueアプリケーションでSpread.Sheetsを使用する
これで、Spread.SheetsをVue.jsアプリケーション内で使用できるようになりました。例として、次のサンプルコードを使用します。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Hello SpreadJS Vue</title>
<link rel="stylesheet" href="lib/gc.spread.sheets.excel2016colorful.0.0.0.css" type="text/css"/>
<style>
#app{
width: 100%;
height:100%;
}
.vue-demo{
width: 800px;
height:400px;
margin: 0 auto;
}
</style>
</head>
<body>
<div id="app">
<app></app>

<script type="text/x-template" id="app-template">
<div>
<gc-spread-sheets
v-bind:hostClass='hostClass'
@workbookInitialized='spreadInitHandle'
>
<gc-worksheet >
</gc-worksheet>
</gc-spread-sheets>
</div>
</script>
<script type="text/javascript">
window.onload = function () {
Vue.component('app', {
template: '#app-template',
data:function () {
return {
hostClass: "vue-demo"
}
},
methods: {
spreadInitHandle: function (spread) {
window.mySpread = spread;
console.log('now you can also get spread from window');
}
}
});
new Vue({
el:"#app",
})
}
</script>
</body>
</html>
<gc-spread-sheets>、<gc-worksheet>、および、<gc-column>は、タグ階層の基本要素です。他の要素は、それぞれ設定して使用します。なお、タグ階層は、以下のとおりです。
<gc-spread-sheets>
<gc-worksheet>
<gc-column></gc-column>
...
</gc-worksheet>
...
</gc-spread-sheets>
以下の各トピックでは、さまざまな要素(ディレクティブ)について説明します。
