Reset to default 6First get the contents of the label, then use the regex /-/.
> "blabla".match(/-/)
> null
> "bla-bla".match(/-/)
> ["-"]
You don't even need a regex here, you can use indexOf:
> "blabla".indexOf('-')
> -1
> "bla-bla".indexOf('-')
> 3
If you just want to select the label element if it contains a "-", you could use:
$('label:contains("-")')
It depends on what you are trying to do.
