你可以通过isSelected方法来获取或设置一个表单的选择状态，例如：
活动工作表始终处于选中状态，不能设置为未选中状态。
如果使用isSelected方法将活动工作表设置为未选中，则活动但未选中的工作表将具有另一个工作表标签视图。
您还可以通过使用Shift / Ctrl键单击来更改一个或多个表单的选定状态（在MacOS中，您需要使用Shift / Command键）
当更改工作表的选定状态时，Spread还提供两个事件：
Spread支持批量删除和隐藏多个选定工作表的功能。
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(_getElementById('ss'), { sheetCount: 5 });
initCheckBoxesEvent(spread);
initSpread(spread);
};
function initCheckBoxesEvent(spread) {
var sheetsNames = ["Sheet1", "Sheet2", "Sheet3", "Sheet4", "Sheet5"];
sheetsNames.forEach(function (name) {
document.getElementById(name).addEventListener('change', function (e) {
var sheet = spread.getSheetFromName(name);
if (sheet) {
sheet.isSelected(this.checked);
spread.repaint();
}
});
});
}
function initSpread(spread) {
var sheet1 = spread.getSheetFromName("Sheet1");
var sheet2 = spread.getSheetFromName("Sheet2");
var sheet3 = spread.getSheetFromName("Sheet3");
sheet1.isSelected(true);
sheet2.isSelected(true);
sheet3.isSelected(true);
spread.bind(GC.Spread.Sheets.Events.SheetChanged, function (e, args) {
var checkboxElement = document.getElementById(args.sheetName);
if (checkboxElement) {
checkboxElement.checked = !checkboxElement.checked;
}
});
spread.repaint();
}
function _getElementById(id) {
return document.getElementById(id);
}
