你可以使用 setDataSource 和 getDataSource 方法来设置获取数据源。 在设置数据源之前, 你可以使用 autoGenerateColumns 方法来控制是否自动生成绑定列。 例如:
你也可以使用 getDataItem 方法来获取指定行的数据信息。
你可以像这个例子版将数据字段绑定到指定的列:
var _lines = ["Computers", "Washers", "Stoves"];
var _colors = ["Red", "Green", "Blue", "White"];
var _ratings = ["Terrible", "Bad", "Average", "Good", "Great", "Epic"];
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 2 });
initSpread(spread);
};
function Product(id, line, color, name, price, cost, weight, discontinued, rating) {
this.id = id;
this.line = line;
this.color = color;
this.name = name;
this.price = price;
this.cost = cost;
this.weight = weight;
this.discontinued = discontinued;
this.rating = rating;
}
function getProducts(count) {
var dataList = [];
for (var i = 1; i <= count; i++) {
var line = _lines[parseInt(Math.random() * 3)];
dataList[i - 1] = new Product(i,
line,
_colors[parseInt(Math.random() * 4)],
line + " " + line.charAt(0) + i,
parseInt(Math.random() * 5001) / 10.0 + 500,
parseInt(Math.random() * 6001) / 10.0,
parseInt(Math.random() * 10001) / 100.0,
!!(Math.random() > 0.5),
_ratings[parseInt(Math.random() * 6)]);
}
return dataList;
}
function initSpread(spread) {
spread.suspendPaint();
spread.options.tabStripRatio = 0.8;
var products = getProducts(100);
var sheet = spread.getSheet(0);
sheet.name("Default binding");
sheet.setDataSource(products);
var sheet2 = spread.getSheet(1);
sheet2.name("Custom binding");
sheet2.autoGenerateColumns = false;
sheet2.setDataSource(products);
var colInfos = [
{ name: "id", displayName: "ID" },
{ name: "name", displayName: "Name", size: 100 },
{ name: "line", displayName: "Line", size: 80 },
{ name: "color", displayName: "Color" },
{ name: "price", displayName: "Price", formatter: "0.00", size: 80 },
{ name: "cost", displayName: "Cost", formatter: "0.00", size: 80 },
{ name: "weight", displayName: "Weight", formatter: "0.00", size: 80 },
{ name: "discontinued", displayName: "Discontinued", cellType: new GC.Spread.Sheets.CellTypes.CheckBox(), size: 100 },
{ name: "rating", displayName: "Rating" }
];
sheet2.bindColumns(colInfos);
spread.resumePaint();
};
