验证单元格值是否满足数据验证规则
验证单元格值是否符合数据验证规则
有时,动态验证给定值是否满足应用于单元格的数据验证规则是必要的。为此,Aspose.Cells API提供了cell.getValidationValue()方法。如果单元格中的值不满足应用于该单元格的数据验证规则,则返回False,否则返回True。
使用以下示例 Microsoft Excel 文件与下面的示例代码一起测试 cell.getValidationValue() 方法。从快照中可以看到,单元格 C1 应用了 十进制数据验证,并且只接受 10 到 20 之间的值。每当单元格的值在 10 到 20 之间,cell.getValidationValue() 方法会返回 True,否则返回 False。
以下示例代码说明了 cell.getValidationValue() 方法的工作原理。首先,它将值 3 输入到 C1 中。因为这不符合数据验证规则,cell.getValidationValue() 方法返回 False。然后,它将值 15 输入到 C1 中。因为这个值符合数据验证规则,cell.getValidationValue() 方法返回 True。类似地,对值 30 返回 False。
用Java代码验证单元格值是否符合数据验证规则
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getDataDir(VerifyCellValueSatisfiesDataValidationRules.class); | |
// Instantiate the workbook from sample Excel file | |
Workbook workbook = new Workbook(dataDir + "Sample1.xlsx"); | |
// Access the first worksheet | |
Worksheet worksheet = workbook.getWorksheets().get(0); | |
/* | |
* Access Cell C1. Cell C1 has the Decimal Validation applied on it.It can take only the values Between 10 and 20 | |
*/ | |
Cell cell = worksheet.getCells().get("C1"); | |
// Enter 3 inside this cell. Since it is not between 10 and 20, it should fail the validation | |
cell.putValue(3); | |
// Check if number 3 satisfies the Data Validation rule applied on this cell | |
System.out.println("Is 3 a Valid Value for this Cell: " + cell.getValidationValue()); | |
// Enter 15 inside this cell. Since it is between 10 and 20, it should succeed the validation | |
cell.putValue(15); | |
// Check if number 15 satisfies the Data Validation rule applied on this cell | |
System.out.println("Is 15 a Valid Value for this Cell: " + cell.getValidationValue()); | |
// Enter 30 inside this cell. Since it is not between 10 and 20, it should fail the validation again | |
cell.putValue(30); | |
// Check if number 30 satisfies the Data Validation rule applied on this cell | |
System.out.println("Is 30 a Valid Value for this Cell: " + cell.getValidationValue()); | |
示例代码生成的控制台输出
这是在上面显示的示例Excel文件执行示例代码生成的控制台输出。
Is 3 a Valid Value for this Cell: False
Is 15 a Valid Value for this Cell: True
Is 30 a Valid Value for this Cell: False
