基本应用

数据验证是一个你可以使用定义的约束来表明一个单元格上可以或者应该设置什么样的数据的特性。你可以通过配置数据验证来阻止用户输入无效的数据。如果你有一个数据源是从用户输入的数据集合来的表单,当你想要控制用户输入的数据来适应表格的要求,那么这将是非常有用的。

要为工作表添加一个数据验证器,应该创建一个验证器然后将其添加到工作表上。例如: 你可以创建如下的六种验证器: createNumberValidator:创建基于数字的验证器。 createDateValidator:创建基于日期的验证器。 createTextLengthValidator: 创建基于文本长度的验证器。 createFormulaValidator: 创建基于公式的验证器。 createFormulaListValidator: 创建基于公式列表的验证器。 createListValidator: 创建基于列表的验证器。 在你为一个单元格设置验证器之后,你可以调用 getDataValidator 方法来获取单元格上的数据验证器。你也可以调用 isValid 方法来判定单元格的值是否是有效的。例如: 你可以调用 highlightInvalidData 属性来获取或者设置是否要高亮显示无效的数据。如果它被设置为 true ,那么当单元格中的数据无效时,单元格中会显示一个红色的圆圈。
