Text validation for TextInput in Flex

Posted Date: 20 Jun 2008	Resource Type: Code Snippets	Category: Regular Expressions

In flex, a text input is a textbox. In forms, we always have a requirement to validate user input before accepting the form completely.

In flex, we can restrict input with the following code.


    <mx:TextInput restrict="A-Z a-z 012345689" />

The example code above restricts the input text to only alphanumeric characters. The restrict attribute of a TextInput facilitates such a restriction.
