Any autocomplete dropdown, use this code
$(document).ready(function () {
var orgid = "0";
getSeverityList(orgid);
var $advAutoComplete = $('#addForm87 input[name="orgs_id"]');
$advAutoComplete.each(function()
{
var $el = $(this);
$el.on( "autocompletechange", function( event, ui )
{
orgid = $(event.target).attr('data-selectedid');
getSeverityList(orgid);
});
});
});
Html is like this
<div style="" class="mui-textfield ui-front mui-col-md-6">
<input name="orgs_id" class="autoCompCollAdv mui--is-empty ui-autocomplete-input mui--is-dirty" type="text" data-returnpropname="orgs_id" data-coll="12" data-alias="o" data-columns="{'ValueProperty':'_id', 'DisplayProperties':['_id','name'], 'FilterDBCols':['_id','name'], 'RunOnFocus':'true', 'Functions':{'Focus':'FocusFunc','Type':'TypeFunc'}, 'PermDBFilters':[] }" value="" data-modalid="addModel87" required="" data-dirty="0" data-selectedid="" autocomplete="off" data-oldval="">
