When an App is created in Canvas, it does not expect any JavaScript code to be created by default. The following details are provided for scenarios where there is a need to listen to user interaction with the App and handle those events as appropriate.
The following sample code is a simple JS class for an App with the Id BEN_SUMMARY_LIST. Assuming the file name is beneficiarySummaryClassicList.js
CWEH.registerHandler('BEN_SUMMARY_LIST', CWEC.CELL_CLICK, function(colId, colValue, rowData)
{
// Cell click logic goes here
});
