General
Disabled dialog elements
Are always validated, i.e. an error message appears when sending the step if validation fails for such an element.
Hidden dialog elements
The required field validation does not take place. Other validations, such as whether it is a numeric value, are usually performed anyway.
Textbox
You have the possibility of check the validity of the input value of a form element of type Textbox.
The following properties are available for validation:
Properties |
Description |
|---|---|
None |
No validation |
Alphanumeric |
Only alphanumeric characters |
Numeric |
Only numeric characters |
Decimal |
Here you can determine the precision (decimal places) in an additional field. |
Date |
You can specify the format of the date. |
Regular Expression |
You can enter a regular expression and a matching error message. |
Regular expressions
With a regular expression, an input value can be checked more precisely for its validity.
Example 1: A part of the input must consist of two consecutive letters and six consecutive digits (e.g. InNo012345).
[a-zA-Z]{4}[0-9]{6}
Example 2: The input must be a valid e-mail address (e.g. info@jobrouter.de).
[a-zA-Z0-9-.]{1,}[@]{1}[a-zA-Z0-9-.]{2,}\w{1,}\.{1}[a-zA-Z]{2,6}
In order to create regular expressions in advance and to check them with a test string, we recommend the site https://regex101.com/.
Please note: The modifiers/flags Global: g, Multiline: m, Case insensitive: i, Ignore whitespaces: x, Single line: s, Unicode: u, eXtended: X, Case Ungreedy: U, Anchor: A and Duplicate group names: J are not permitted in the regular expression and do not lead to the expected result when the input value is checked.
