我试图使用ajax显示与所选类别相关的数据。它仅适用于最后选定的术语，而不适用于所有选定的术语。任何帮助都将不胜感激。

var selected_cat = $(\'#my-categorychecklist input:checked\').map(function() {
    return this.value
}).get();

   $(document).ready( function () {
         var getid = $(\'#my-categorychecklist input:checked\').last().val();
         var matchid = $(\'#my-categorychecklist input:checked\').last().val();

         $(\'#section\').html(\'<div class="spinner"></div>\');
         var data = {
             \'action\': \'fields_selected\',
             \'post_id\': $(\'#fields-list-selected\').data(\'post_id\'),
             \'term_id\': selected_cat
         };

             $.post(ajaxurl, data, function (response) {
                     if(response != 0) {
                         $(\'.block\'+getid).html(response);
                         $(\'[data-toggle="tooltip"]\').tooltip();
                     } else {
                         $(\'.block\'+getid).html(" ");
                         $(\'[data-toggle="tooltip"]\').tooltip();
                     }
             });
