<h1>SheetJS + Dojo Memory Store Demo</h1>
|
||
|
|
<br/>
|
||
|
|
This demo fetches <a href="https://sheetjs.com/pres.xlsx">https://sheetjs.com/pres.xlsx</a>, parses the file, generates a Memory store from the first worksheet, and loads a Combo box. When a President is selected, the text box will display the "Index" field from the dataset.
