How to update the Repeatable fields in Joomla 3 with jQuery

Question

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"]}';
jQuery('#jform_repeatable_id').val(fer);

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

Answer 1

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

jQuery(document).ready(function(){
  jQuery('#jform_repeatable_id').val('json string of your new value');
})
