Spread.Sheets 支持将工作表绑定到数组或者 Knockout.observableArray。
Spread.Sheets 也支持单元格级别的绑定。单元格级别的绑定可以绑定到任何对象上。
Spread.Sheets 的数据绑定为双向绑定。
使用 bindColumn 方法来绑定特定的列。

示例代码
以下代码使用 bindColumn 方法绑定了特定的列。
| JavaScript | Copy Code |
|---|---|
| var datasource = [ { name: "Alice", age: 27, birthday: "1985/08/31", position: "PM" }, { name: "Aimee", age: 28, birthday: "1984/07/31", position: "TL" }, { name: "Charles", age: 29, birthday: "1983/03/31", position: "QC" }, { name: "Fred", age: 30, birthday: "1982/02/20", position: "DL" }, { name: "Angelia", age: 31, birthday: "1981/05/30", position: "QC" }, { name: "Peter", age: 32, birthday: "1980/11/08", position: "QC" } ]; var nameColInfo = { name: "name", displayName: "Name", size: 70 }; var ageColInfo = { name: "age", displayName: "Age", size: 40, resizable: false }; var birthdayColInfo = { name: "birthday", displayName: "Birthday",formatter:"d/M/yy", size: 120 }; var positionColInfo = { name: "position", displayName: "Position", size: 50, visible: false }; activeSheet.autoGenerateColumns = true; activeSheet.setDataSource(datasource); activeSheet.bindColumn(0, nameColInfo); activeSheet.bindColumn(1, ageColInfo); activeSheet.bindColumn(2, birthdayColInfo); activeSheet.bindColumn(3, positionColInfo); | |
示例代码
以下代码使用 bindColumn 绑定了特定的列。
| JavaScript | Copy Code |
|---|---|
| var test = [ {"Series0":2,"Series1":1}, {"Series0":4,"Series1":2}, {"Series0":3,"Series1":4} ]; activeSheet.setDataSource(test); activeSheet.bindColumn(1,"Series0"); activeSheet.bindColumn(0,"Series1"); | |
示例代码
以下代码使用 setDataSource 将数据和工作表绑定在了一起。
| JavaScript | Copy Code |
|---|---|
| var test = [ {"Series0":2,"Series1":1}, {"Series0":4,"Series1":2}, {"Series0":3,"Series1":4} ]; activeSheet.setDataSource(test, true); //activeSheet.setDataSource(test); | |
示例代码
以下代码示例了如何绑定到一个 JSON 格式的数据源。
| JavaScript | Copy Code |
|---|---|
| var jasonArray = '{"phoneNumbers": [{"type": "home","number": "212 555-1234"},{"type": "fax","number": "646 555-4567"}]}'; var arr = JSON.parse(jasonArray); activeSheet.setDataSource(arr.phoneNumbers); | |
