The purpose of the script, again, is to set the record boundary when EITHER the year OR the
artist changes.
The script would look like this:
/* Read the values of both columns we want to check */
var zeBand = boundaries.get(region.createRegion(1,1,30,1));
var zeYear = boundaries.get(region.createRegion(61,1,65,1));
/* Check that at least one of our variables holding previous values
have been initialized already, before attempting to compare the
values */
if (boundaries.getVariable("lastBand")!=null) {
(zeBand[0]!=boundaries.getVariable("lastBand") || zeYear
[0]!=boundaries.getVariable("lastYear"))
{
boundaries.set();
}
}
boundaries.setVariable("lastBand",zeBand[0]);
boundaries.setVariable("lastYear",zeYear[0]);
This script uses the exact same code as used for CSV files, with the exception of parameters
expected by the createRegion() method. The get method adapts to the context (the data source
file) and therefore expects different parameters to be passed in order to achieve the same thing.
Since a text file does not contain column names as a CSV does, the API expects the text
regions to be defined using physical coordinates. In this instance: Left, Top, Right, Bottom.
To try this code, paste the data into a text editor and save the file to Albums.txt. Then create a
new DataMapper configuration and load this Text file as your data file. In the Data Input
Settings, specify On lines as the Page delimiter type with the number of lines set to 1. When
you now set the boundary Trigger to On script, the file will be processed line per line
(triggering the event on each line). Paste the above code in the JavaScript expression field and
click the Apply button to see the result.
Note
The PDF context also expects physical coordinates, just like the Text context does, but since PDF
