Custom Coding with the JSON API

If you need to add some custom code to your App for very special requirements,  there are 2 events triggered by the Json API that can be useful.

In order to respond to these events, you can select the events tab of the Widget properties panel,, and then access to the events onJSONdataLoadSuccess and onJSONdataLoadError:

By Selecting an event Handler, the event code will be automatically added to the custom.js file:

onRepeaterDataLoaded Event

Example of code

This event handler implements 2 parameters:

• repeater:  a DOM reference to the Repeater in the current context
  

• Items: a js object with the loaded data
  

  

  Example in the Safari Debugger

onLineChange Event

This event handler implements 4 parameters:

• event: the current event
  

• repeater:  a DOM reference to the Repeater in the current context
  

• rowindex:  index of the selected line (starts with 0)
  

• item: the current record as a JS object
