I have looked in the /media/system/js/repeatable-uncompressed.js file but could only find events that trigger after the init of JRepeatable.

Is there a way to update the input value of the repeatable field, and then initialize a new draw or build of the repeatable fields based on the new values.

To update the value of the repeatable field is easy:

var fer = '{"key":["1","38","3","13","23"],"cpe":["3","2","3","3","2"],"mbr":["3","2","3","3","2"],"mtr":["3","2","3","2","2"]}';

But to get it to initialize based on those new values is what I need.

By default Repeatable initialised on load event, so you have time to change the value on ready event, that occurs before load event.

  jQuery('#jform_repeatable_id').val('json string of your new value');
  • I need to change the values some time later when the user clicks on another field.

  • hm, unfortunately I do not see a way to do this .. you still can set jQuery('#jform_repeatable_id').val('json string of your new value') but it will not affect existing instance, and can be reseted ...
