Here is my code: searchform.php <script type=”text/javascript” src=”http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js” ></script> <script type=”text/javascript”> $(function(){ $(‘#apskritis’).change(function(){ var $apskritisSlug=$(‘#apskritis’).val(); // call ajax $(“#savivaldybe”).empty(); $(“#miestas_kaimas”).empty(); $.ajax({ url:”/wp-admin/admin-ajax.php”, type:’POST’, data:’action=get_savivaldybes&apskritis_slug=’ + $apskritisSlug, success:function(results) { //alert(results); $(“#savivaldybe”).removeAttr(“disabled”); $(“#savivaldybe”).append(results); } }); } ); $(‘#savivaldybe’).change(function(){ var $savivaldybeSlug=$(‘#savivaldybe’).val(); // … Read more
