Hi every one,
I have a text field called control. This field should allow the following kind of values.
1) 1.2.3;4 : a) If I give some other value I should show error
2) 1.2.1_a.te.st_;6 : b) Here when I enter '_' then its mandatory to enter some char or no's next to '_'. For second '_' its not necessary to enteranything.
c) Need to block continous two dot like this(1.2.3...1;5)
Which means I need to check the validation after second dot (.) to (;) I can enter dot(.),char, no's , '_' and want to apply the mentioned conditions(b) also.
I tried out this reg exp but I don't know how to add conditions in that. Can anyone tell me how to do this validation?
/[0-9]{1,}.[0-9]{1,}.[0-9a-zA-Z._']{1,};[0-9a-zA-Z]{1,}/g;
Thanks in advance,
