シリアライズ(データ)

シートまたはテーブルのデータソースをJSONにシリアル化できます。

<p>JSONにシリアル化するには、対象オブジェクトの<strong>includeBindingSource</strong>プロパティをtrueに設定してSpread.toJSONを呼び出します。これにより、JSONにシリアル化する場合に、Spreadインスタンスが連結されていた実際のデータソースを簡単に含めることができます。このJSONを別のSpreadインスタンスにロードする場合も、このデータソースはすでに含められているため、Spreadとデータソースを再度連結する必要がありません。</p> <pre><code class="hljs js language-js"> sheet.setDataSource(dataSource); <span class="hljs-keyword">var</span> spread1 = GC.Spread.Sheets.findControl(<span class="hljs-built_in">document</span>.getElementById(<span class="hljs-string">'ss'</span>)); <span class="hljs-keyword">var</span> jsonString = <span class="hljs-built_in">JSON</span>.stringify( spread1.toJSON( { <span class="hljs-attr">includeBindingSource</span>: <span class="hljs-literal">true</span> } ) ); </code></pre>
