Open the demo in new window can open the designer
The preserve formula setting is very useful when you want to retain formulas in the exported Excel file.
You can use the following code to set the preserve formula setting:
window.onload = async () => {
const loadingTip = addLoadingTip();
const { spread, designer } = createSpreadAndDesigner();
const res = await fetch('$DEMOROOT$/zh/sample/features/report-sheet/preserve-formula-in-export/spread.json');
await spread.fromJSON(await res.json());
loadingTip.remove();
if (designer) {
designer.refresh();
}
if (designer) {
document.querySelector('sjs-report-toolbar').remove();
document.querySelector('#demo-host').style.height = '100%';
} else {
document.querySelector('sjs-report-toolbar').attachSpread(spread);
}
}
function createSpreadAndDesigner() {
const demoHost = document.getElementById('demo-host');
if (window !== top) {
return {
spread: new GC.Spread.Sheets.Workbook(demoHost, { sheetCount: 1 }),
}
} else {
const designer = new GC.Spread.Sheets.Designer.Designer(demoHost, undefined, undefined, { sheetCount: 1 });
return {
designer,
spread: designer.getWorkbook(),
}
}
}
function addLoadingTip() {
const div = document.createElement('div');
div.style.position = 'absolute';
div.style.inset = '0';
div.style.display = 'flex';
div.style.alignItems = 'center';
div.style.justifyContent = 'center';
div.style.background = 'white';
div.style.zIndex = '100';
div.textContent = 'Loading data from server ...';
document.body.appendChild(div);
return div;
}
