jQuery.ajax({
            type: "POST",
            url:"wp-admin/admin-ajax.php",
            data:\'action=nafham_list_cats_selection&selection_id=\' + $selection_id,
            success:function(results){
                jQuery(".semester_selection").empty();
                jQuery(".semester_selection").prop(\'disabled\', false);
                jQuery(".semester_selection").append(results);
            }
        })

这是ajax调用I\'ms的结尾，下面是发送数据的函数：

function nafham_list_cats_selection() {
    if(isset($_POST[\'selection_id\'])){ 
        nafham_get_listed_cats($_POST[\'selection_id\']);

    }
}

如何让函数输出两个值，以便使用

success:function(results1, results2){

$results[\'args1\'] = "value1";
$results[\'args2\'] = "value2";

echo json_encode($results);

success:function(results){
jQuery(".semester_selection1").append(results.args1); // This appends value1
jQuery(".semester_selection2").append(results.args2); // This appends value2
}
