可见性

SpreadJS 允许隐藏或者显示表单。如果你想访问某个表单的数据,但是又不想让用户看见的时候,这个功能很有用。

使用 “sheet.visible()” 方法和 sheetTabVisible 来改变工作表是否可见或获取工作表的可见状态。 可见状态: hidden:工作表标签被隐藏,等于false。 visible:工作表标签可见,等于true,为sheetTabVisible的默认值。 veryHidden:工作表选项卡深度隐藏。 如果你想在Spread组件中获得一个sheet的可见状态,你只需要下面的代码: 如果你想在 Spread 控件隐藏一个表单, 你只需要执行以下代码: 如果你想在 Spread 组件中深度隐藏一个工作表(这意味着它不能通过 UI 取消隐藏),你只需要执行以下代码:
window.onload = function() { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); document.getElementById("btnVisible").addEventListener('click',function() { for (var i = 0; i < spread.sheets.length; i++) { if (spread.sheets[i].visible() === 0) { spread.sheets[i].visible(true); break; } } }); document.getElementById("btnInvisible").addEventListener('click',function() { var sheet = spread.getActiveSheet(); if (sheet) { var activeIndex = spread.getActiveSheetIndex(); if (activeIndex - 1 >= 0) { spread.setActiveSheetIndex(activeIndex - 1); } sheet.visible(false); } }); document.getElementById("btnShowVeryHidden").addEventListener('click',function() { for (var i = 0; i < spread.sheets.length; i++) { if (spread.sheets[i].visible() === 2) { spread.sheets[i].visible(true); break; } } }); document.getElementById("btnVeryHidden").addEventListener('click',function() { var sheet = spread.getActiveSheet(); if (sheet) { var activeIndex = spread.getActiveSheetIndex(); if (activeIndex - 1 >= 0) { spread.setActiveSheetIndex(activeIndex - 1); } sheet.visible(2); } }); }; function initSpread(spread) { var sheet = spread.getActiveSheet(); }
