Validating user-entered data in form CTAs

Form CTAs allow you to collect data entered by users. JotUrl does not validate this data in any way, but classifies it simply by distinguishing the email addresses from what is not an email address. However, it is possible to insert a validation using JavaScript regular expressions: in the last step of the CTA form click on advanced options and enter a regular JavaScript expression for validation.

The user interface also allows you to check the entered regular expression, just click on Check, a validation interface will be displayed.

 

The JavaScript RegExp Object

A regular expression is an object that describes a pattern of characters.

Regular expressions are used to perform pattern-matching and "search-and-replace" functions on text.

 

Syntax

The syntax of a regular expression object is 

/pattern/modifiers

For example:

• /joturl/i  is a regular expression
• joturl is a pattern
• i  is a modifier
