Javascript (JS) question - store and retrieve values

The Javascript question is in itself not storing any data in the survey. To store and retrieve respondent actions, you need to implement the following code in your javascript

To store data from javascript:

  1. window.parent.postMessage(JSON.stringify(state), '*');
To retreive data from database into javascript:

  1. bindEvent(window, 'message', function (e) {
  2. console.log('Listen to messages from parent window ', e.data);
  3. const state = e.data;
  4. });
Also, you can use a global variable "elementsData" in the js component which already contains a saved state.

Getting stored values in a survey:

The JSON value you store and retrieve will be exported as text data in the survey CSV export.
