Flex regex versus java regex + howto embed regex in flex

Tuesday, 04 January 2011 04:33

// Only allow 6 to 9 digits (and no more)
Flex: ^\d{6,9}$
Java: \\d{6,9}

Following code will NOT function as desired (the {} are interpreted as binding markers, thus not part of the regex):



    source="{te_value}" 

    property="text" 

    expression="^\d{6,9}$" 

    required="true" 

    flags="g"

    trigger="{te_value}" 

    triggerEvent="change"/>

Following code will function as desired:



 ..

   public var regex:String = "^\\d{6,9}$";

   ..



    source="{te_value}" 

    property="text" 

    expression="{regex}" 

    required="true" 

    flags="g"

    trigger="{te_value}" 

    triggerEvent="change"/>
