rules_onConfgure(data)
When a configuration code is read, rules_onConfigure() is called with the contents of
the configuration code as data. If the configuration data is handled in
rules_onConfigure(), the value “true” is returned which will stop further action by
reader.onConfigure().
In the example below, the rules_onConfigure() calls
jsSettings.parseUserParams() to scan the configuration data for a JavaScript user
parameter command and returns “true” if the configuration data was handled successfully,
otherwise “false”.
Example:
include(".settings.js");
rules_onConfigure = function(data)
{
if( jsSettings.parseUserParams )
return jsSettings.parseUserParams(data);
return false;
};
Optional Global variables
The writer can include global variables in JavaScript Rules file, outside any of the pre-defined
functions. These variables will be instantiated when the reader starts, as the JavaScript engine
starts.
.setttings.js
Code provides the ability to store persistent user settings by including “.settings.js” to an application
or rules file. Configuration barcodes may be created and must match the following format:
<JS Identifier> JSUP <P | S | R | G> <PP> <Val>, where
<JS Identifier>: Identifier indicating that this command is to be handled exclusively by JavaScript:
\x1
JS: Primary Category
UP: Sub Category
<P | S| R | G>: Action: Put, Set, Reset, or Get
<PP>: Two character parameter ID
<Val>: Quoted (optional) string
Example 1:
\x1bJSUPSP01 ≈ JSUPSP0”1”
Example 2:
\x1bJSUPSP1”exampleString” ≈ \x1bJSUPSP1exampleString
