工作代码......只需使用async：false

jQuery.validator.addMethod("uniquerheading", function(value, element) { 

        $action_name = 'checkunquieannoucementheading';
        var response = false;
        var url = '<?php echo "$module_name/$controller_name/checkunquieannoucementheading"; ?>';
            $.ajax({
            url: url,
            type: 'get',
            data: {
                    "txt_heading":value             
            },
            success: function(data) {               
                // Display list on the page by replacing the content on existing, get from the controller-action
                response =  data;
            },
            async:   false
        })

        return response;

}, "Annoucement heading already used");
