Javascript and regexp

[zillaZ]

Hi all.

I'n new in regexp and I wonder how can check is value valid.

valid value is 7-9 numbers long and in the beginning there can be #-character

So values: 4398733 and #384 are ok, but
values 3455 or #477938742983 aren't.

I have tried something like this, but this is not correct

val.match(/^\#\d{7-9}$/))

Hi

Are you sure ? "#384" is not 7-9 character long.

Anyway
[ul]
[li]no need to escape #[/li]
[li]zero or one of something can be specified with the [tt]?[/tt] quantifier[/li]
[li]in the [tt]{}[/tt] quantifier the limits are separated with comma ( , )[/li]
[/ul]

val[teal].[/teal][COLOR=darkgoldenrod]match[/color][teal]([/teal][fuchsia]/^#?\d{7,9}/[/fuchsia][teal])[/teal]

Hi

Oops. Now I see that somehow I removed the [tt]$[/tt] for matching at the end. That is still necessary :

val[teal].[/teal][COLOR=darkgoldenrod]match[/color][teal]([/teal][fuchsia]/^#?\d{7,9}$/[/fuchsia][teal])[/teal]
