Import Script Libraries
You can import scripting code from JavaScript or Groovy files that are accessible from the local server using the
src attribute in the <script> statement. To use external code, you must deploy these scripts in the
Presto Server. See
Deploying Groovy or JavaScript Scripts in
Presto for more information on using external scripts.
For example:
<script type="text/javascript" src="myFunctions.js"
inputvariables="$order, $customer"
outputvariable="$scriptResult"/>
...
<script type="ruby" src="myRubyScript.rb"
inputvariables="$order, $customer"
outputvariable="$scriptResult"/>
The script has access to any variables that you pass in inputvariables. Order or input parameters is not important. The result of the script, if any, is placed in outputvariable.
