How to filter textfield

[jo_bonanno]

How to code in Textfield expression if I wanted to make a simple label change base on the query result as per the below...

 

If $F{abc} = J

display "Job"

else if $F{abc} = E

display "event"

else display "Others"

You can either

• use the "? :" Java operator (the code assumes that $F{abc} is a java.lang.Character, you can adapt the code otherwise):

  Code:

• Write a decoding method in some accessible class and use it:
  

  Code:

  DecodeHelper.decodeABC($F{abc})[/ul]

I have change it to

 

$F{acType}.charValue == "J"?"JOB" : ($F{acType}.charValue() == "E"?"Even")

 

but what I rcvd were error messages... Would be great if u could check for me. thanks.

First of all, is acType a java.lang.Character field or not?

 

The code I posted contains a syntax error (should start with $F{abc}.charValue() == ..), it was only meant to give you an idea of what a decoding expression would look like. You have further syntax errors in your expression: character literals use single quotes ('J'), and the "? :" operator is incomplete.

 

JR expressions are Java expressions (if you use a Java-based report compiler) with param/field/var placeholders, so familiarity with Java expression syntax is a prerequisite for writing complex expressions.

Ok now Ive got it... the amended syntax is as per below:

 

$F{acType}.equals("J") ? "JOB" : $F{acType}.equals("E") ? "Even" : $F{acType}

 

Thanks bro
