表格绑定

表格绑定是一种特定的单元格级别绑定; 它可以为表格提供数据。

使用 bindingPath 方法来绑定表格到数据记录, 然后绑定表格的列到数据记录的数据字段。 例如: 当您设置其他数据源时,该表格将自动绑定到相应的记录。 我们还提供了一种简单的方法 bind API以解决复杂的调用问题,您可以通过以下代码使用它,例如: 绑定数据源时,更改数据源后可以得到脏数据项:
var spreadNS = GC.Spread.Sheets; window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { //define BindingPathCellType function BindingPathCellType() { spreadNS.CellTypes.Text.call(this); } BindingPathCellType.prototype = new spreadNS.CellTypes.Text(); BindingPathCellType.prototype.paint = function (ctx, value, x, y, w, h, style, context) { if (value === null || value === undefined) { var sheet = context.sheet, row = context.row, col = context.col; if (sheet && (row === 0 || !!row) && (col === 0 || !!col)) { var bindingPath = sheet.getBindingPath(context.row, context.col); if (bindingPath) { value = "[" + bindingPath + "]"; } } } spreadNS.CellTypes.Text.prototype.paint.apply(this, arguments);
