Hi All,

Im using Flex RegExpValidator. Can anyone suggest me the correct expression to validate this condition?....

I have tried this expression :----- /^[^///\/</>/?/*&]+$/...But in this it is also negating the alphabets.Also I have tried with opposite condition that in the String we should have alphabets and the expression is:-- ([a-z]|[A-Z]|[0-9]|[ ]|[-]|[_])*..... Please can anyone help me on this.

Thanks in advanced to all.

Munira

Hi ,

Thanks for your reply.I have tried this condition.

And got following result:--

If you give only alphabets with no special symbols.The expression is valid

that is what is my requiremnet.

If you give only special characters .Expression is invalid what is our

requiremnet.

But if you give mixed expression of Special symbols and alphanumeric

characters it is considering it as Valid .

did you use

var pattern:RegExp = /^[a-zA-Z0-9 -_]*$/;

or

var pattern:RegExp = /^[a-zA-Z0-9 \-_]*$/;

remember - needs to be escaped since it's used to indicate a range of values
