正如我提到的here 这两个ajax操作，下面是如何使用第二个操作以db格式提取表单值

创建将返回设置选项的ajax操作

您可以将此代码添加到{theme}/functions.php 或至{theme}/inc/hooks.php

function _action_ajax_fw_theme_get_settings_options() {
    wp_send_json_success(array(
        \'options\' => fw()->theme->get_settings_options()
    ));
}
add_action( \'wp_ajax_fw_theme_get_settings_options\', \'_action_ajax_fw_theme_get_settings_options\' );

var dbSettingsOptions = {
    $form: jQuery(\'.fw-settings-form\'),
    options: null,
    getOptions: function (callback) {
        if (this.options) {
            return callback(this.options);
        }

        jQuery.ajax({
            url: ajaxurl,
            type: \'POST\',
            data: \'action=fw_theme_get_settings_options\',
            dataType: \'json\',
            success: _.bind(function (response, status, xhr) {
                if (!response.success) {
                    alert(\'Ajax error\');
                    return;
                }

                this.options = response.data.options;

                callback(this.options);
            }, this),
            error: function (xhr, status, error) {
                alert(\'Ajax error\');
            }
        });
    },
    getValues: function(callback) {
        if (!this.options) {
            return this.getOptions(_.bind(function(){
                this.getValues(callback);
            }, this));
        }

        jQuery.ajax({
            url: ajaxurl,
            type: \'POST\',
            data: [
                \'action=fw_backend_options_get_values\',
                this.$form.serialize()
                    .replace(/fwf=[^\\&]+\\&/, \'\'), // remove special hidden input value to prevent form save
                \'options=\'+ encodeURIComponent(JSON.stringify(this.options))
            ].join(\'&\'),
            dataType: \'json\',
            success: _.bind(function (response, status, xhr) {
                if (!response.success) {
                    alert(\'Error: \'+ response.data.message);
                    return;
                }

                callback(response.data.values);
            }, this),
            error: function (xhr, status, error) {
                alert(status +\': \'+ error.message);
            }
        });
    }
};

dbSettingsOptions.getValues(function(values){ console.log(values); });
