I know how to split the string within a Controller or Domain class.
But i want to split the string inside the GSP.
My string will look like:
ASD25785-T
I want to be able to split this into 2 strings inside the GSP view.
String a = ASD25785
String b = T
Is it possible to do that inside the GSP?
How about something like this:
<%
String[] tokens = "ASD25785-T".split("-")
String b = tokens[0]
String c = tokens[1]
%>
NB . use try catch because you may get ArrayOutofBoundException
It depends if you have a predefind format or you want something generic.
Without try/catch and using the regex find method in String:
<%
String s="ASD25785-T"
String a,b
s.find(/(.+)-(.+)/) { fullMatch, first, second -> [
a=first
b=second
}
%>
If you are certain that there will always be a match, then it is a cute one-liner:
<%
String s="ASD25785-T"
def (a,b) = s.find(/(.+)-(.+)/) { fullMatch, first, second -> [first,second]}
%>
NB: However, if you want to use it in your view, you should create a tag. Grails taglibs are almost trivial to write, and much better to use in GSP code.
http://grails.github.io/grails-doc/2.4.x/ref/Command%20Line/create-tag-lib.html
http://grails.github.io/grails-doc/latest/guide/single.html#taglibs
Here's a string manipulation taglib
class StringsTaglib {
def split = { attrs, body ->
String input= attrs.input
String regex= attrs.regex
int position= attrs.index as Integer
out << input.split(regex)[position]
}
}
you could then use it like this:
a:<g:split input="ASD25785-T" regex="-" index="0"/>
b:<g:split input="ASD25785-T" regex="-" index="1"/>
