defaultValue APIを使用して、セルにデフォルト値／数式を設定することができます。セルが空白の場合、デフォルト値またはデフォルト数式によって計算した値が表示されます。
空白のセルにデフォルト値／数式が適用される場合、セルを編集してもデフォルト値は上書きされません。
APIは以下の通りです:
window.onload = function () {
let spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 1});
spread.suspendPaint();
let sheet = spread.getActiveSheet();
let fbx = new GC.Spread.Sheets.FormulaTextBox.FormulaTextBox(document.getElementById('formula'), {rangeSelectMode: true});
fbx.workbook(spread);
initSpread(spread, fbx);
bindEvents(spread);
spread.resumePaint();
};
function bindEvents(spread) {
spread.bind(GC.Spread.Sheets.Events.SelectionChanged, function () {
getDefault(spread.getActiveSheet());
});
spread.bind(GC.Spread.Sheets.Events.ActiveSheetChanged, function () {
self.getDefault(spread.getActiveSheet());
});
}
function getDefault(sheet) {
let selections = sheet.getSelections(), showDefault = document.getElementById('showDefault');
if (!selections || selections.length === 0) {
showDefault.value = '';
return;
}
let sel = selections[0], row = sel.row, col = sel.col;
if (sel.rowCount === 1 && sel.colCount === 1) {
showDefault.value = sheet.getDefaultValue(row, col);
} else {
showDefault.value = '';
}
}
function convertValue (value) {
if (!value) {
return value;
}
// try to convert to number
let num = Number(value);
if (!isNaN(num)) {
return num;
}
// try to convert to boolean
if (value.toLowerCase() === "true" || value.toLowerCase() === "false") {
return value.toLowerCase() === "true";
}
// try to convert to date
let date = new Date(value);
if (!isNaN(date.getTime())) {
return date;
}
return value;
}
