Spread.Sheets
SpreadJSでのWijmo DataViewの使用

Wijmo DataViewソース（IDataViewインタフェースを実装）を使用して、ページング、フィルタリング、および並べ替え機能を実装できます。

DataViewソースをSpreadJSで使用するには、次の手順を実行します。

1. JavaScriptsへの参照を追加します。

JavaScript
コードのコピー
<!--JS Reference-->
 ....
 <script type="text/javascript" src="../XXX/globalize.min.js"></script>
 <script type="text/javascript" src="../XXX/knockout-2.1.0.js"></script>
 <script type="text/javascript" src="../XXX/knockout-2.1.0.js"></script>
 <script type="text/javascript" src="../XXX/gcspread.sheets.all.9.20161.0.min.js"></script>
 ....

2. ビューモードを定義し、IDataViewインタフェースを実装します。

3. SpreadJSに連結します。

JavaScript
コードのコピー
<div id="ss" data-bind="gcspread-sheets: { sheetCount:1,
                 activeSheetIndex:0,
                 tabEditable:false,
                 newTabVisible:false,
                 sheets:[
                     {
                         data: products, columns: [
                             { displayName: 'ID', name: 'Product_ID', width:60 },
                             { displayName: 'Product name', name: 'Product_Name', width:260 },
                             { displayName: 'Category ID', name: 'Category_ID', width:100 },
                             { displayName: 'Price', name: 'Unit_Price', width:60 }
                         ]
                     }
                 ]
             }" style="width:850px; height:300px; border: 1px solid black;"></div>

4. IDataView APIを起動し、SpreadJSを更新して結果を表示します。

JavaScript
コードのコピー
<button data-bind="click:clearPaging">pageSize = 0</button>
<button data-bind="click:setPaging">pageSize = 10</button>
<button data-bind="click:prevPage">prev</button>
<button data-bind="click:nextPage">next</button>
