基本应用

SpreadJS包括对180多种形状的支持,其中包括这很多Excel形状。SpreadJS还使用数据驱动的形状来提供更高级的功能,比如说你可以通过源自数据库或者其他数据源的数据来动态生成形状,这些数据源允许你创建交互式形状,例如用于生产车间。

Spread.Sheets支持一下三种形状类型 基础形状: 基础形状可以单独使用。 线条形状: 线条形状即可以单独使用也可以链接其他基础形状。 分组形状: 分组形状并不是一个真实的形状,但是被用作一个形状的管理者,以便方便快捷的操作一组形状。 使用形状功能需要添加如下的JS文件到文档的Head部分: 你可以使用ShapeCollection类上的API来管理所有的形状: 你可以通过sheet.shapes.add方法创建一个基础形状: sheet.shapes.add('autoShape', GC.Spread.Sheets.Shapes.AutoShapeType.heart, 100, 50, 100, 150); 你可以通过sheet.shapes.addConnector方法创建一个线条形状: sheet.shapes.addConnector('connectorShape', GC.Spread.Sheets.Shapes.ConnectorType.elbow, 200, 50, 300, 200); 你可以根据形状的名字来获取或删除一个形状:
