[jQuery] is it a bug with validate?


Hi,
I valiate two fields that depend on each other if blank,for
example,user must supply he/her telephone number or mobile number,he/
her just need input the one of that(telephone number or mobile
number).
I set the rules like this:
rules:{
telephone:{
required:"#mobile:blank",
digits:true
},
mobile:{
required:"#telephone:blank",
digits:true
}
}
if input non-digits characters to both of these two fields,digits
validation is not working.
