Overview

Data validation is a SpreadJS feature that you can use to define restrictions on what data can or should be entered in a cell. You can configure data validation to prevent users from entering data that is not valid. This can be particularly useful if you have a form connected to a database that you want to allow users to enter data in, but you want to restrict the input to fit the restrictions in your database.

To add a data validator to a sheet, create a validator and then add it to the sheet. For example: You can create six kinds of validators, as follows. createNumberValidator: Creates a validator based on numbers. createDateValidator: Creates a validator based on the data. createTextLengthValidator: Creates a validator based on text length. createFormulaValidator: Creates a validator based on a formula. createFormulaListValidator: Creates a validator based on a formula list. createListValidator: Creates a validator based on a list. After you set a validator to a cell, you can use the getDataValidator method to get the cell data validator. And you can use the isValid method to determine whether the cell value is valid. For example: You can use the highlightInvalidData option to get and set whether to highlight invalid data. If you set it to true, then if your value is not valid there will be a red circle on the cell.
