item.setRegex ?

nipper

OK, so from the manual I can do this:

item.setRegex(/^[1-9]$/);

to define the validation regex in formapi.

But what if I want to define a variable and use it as the regex (I am setting an array of choices and will choose the correct one)


val="/^[1-9]$/";
item.setRegex(val);


does not work

Any ideas ?

Your issue is method's Parameter Type, it should not be a String. Method signature is void IWItem.setRegex(RegExp).

So, you can try
var val = /^[1-9]$/; //Note the absence of quoting, /.../ imply RegExp Type

Personally, I would prefer more explicit:
var val = new RegExp("^[1-9]$"); //Note the presence of quoting in the (overloaded) Constructor
