[Ext] Re: Scripted Attribute / weird issue

[Bryan Wooten]

Thanks Brent,

I tried all kinds of escape syntax, none worked on any javascript strings.

But I found a “solution”.

I found that var string = basicAttribute.getValues().toString().replace(“$”,”-“); will successfully get rid of the special char and then I could just split() on ‘-‘.

However for some reason string winds up with the special char ‘[‘ and ‘]’… And those have the same issue as ‘$’…

Anyway with much clugdy code I got the results I needed.

Lesson learned: don’t use special chars for delimiters.

So the split on ‘,’ on the courses string works, but the split on ‘$’ on ca[0] doesn’t do anything.

If I change ‘$’ to ‘2’ it will split on the ‘2’.

Also note that a replace on ‘$’ doesn’t work either.

Any ideas? My google foo is totally failing….


Well, the input to the Java String split() function is a regular expression, and the '$' is a special character. [1]

So if you want to split on a literal '$', you have to escape it.   Try split("\$").  (Or if that doesn't work try split("\\$").  In some cases with string literals in Java you have to have 2 escape characters and I can never remember when/why.  Don't know which case this is.)
