I working on an older legacy system using select2 3.5.2.
It's using the older hidden field method, and it currently passes data like so:
<input class="select2" data-url="/mapscrSearch/filterdata" data-parent="3" data-model="VMapscreenCategories" data-tags="1" data-searchterm="name" data-showitem="name" data-hiddenfield=".opcode_filters" data-allowuserinput="" data-enabled="1" type="text" value="" name="opcode_id" id="opcode_id" tabindex="-1" style="display: none;">
Right now, I have a small jquery function that changes the data-parent on the fly, and pulls in the correct data depending on the parent id; This works if I set data-parent manually, but when changing the data-parent via jquery it doesn't update the select2 component.
For example, I currently have:
$(document).ready(function(){
var opCodeFamily = $('#category_parent');
var opCodeParentId = $('#opcode_parent_id');
var opCodeDataUrl = $('#opcode_id');
// Set default
$(opCodeParentId).val($(opCodeFamily).val());
$(opCodeDataUrl).attr('data-parent', opCodeParentId.val());
// Change the value from parent select
$(opCodeFamily).change(function(){
$(opCodeParentId).val($(opCodeFamily).val());
$(opCodeDataUrl).attr('data-parent', opCodeParentId.val()).trigger("change");
console.log('data-parent set to: ' + opCodeParentId.val() + ', select2 passing: ' + opCodeDataUrl.data('parent'));
}).trigger("change")
});
I can see it changing the data-parent in the console and inspector, but select2 is still passing the original value. I've looked at trigger, but this doesn't seem to do anything. Is there something I'm missing?
