The number of digits before the decimal separator could be validated by setting the “maxValue” editor option. For example if you need a maximum of 3 digits, it could be set to “maxValue: 999” – exceeding it would show a validation notification. The number of digits after the decimal separator could be set by enabling the “maxDecimals” option. Here is a sample snippet showing a maximum of 3 digits before the decimal separator and four after it:
maxDecimals: 4, // 4 digits after the decimal separator
maxValue: 999 // 3 digits before the decimal separator
Also, the igValidator has many options that allow the user to validate the input with more complex logic – like a custom validation function or regular expressions.
