    JSCValue               *value;
    GError                 *error = NULL;

    if (!js_result) {
        g_warning ("Error running javascript: %s", error->message);
        g_error_free (error);
        return;
    }

    value = webkit_javascript_result_get_js_value (js_result);
    if (jsc_value_is_string (value)) {
        gchar        *str_value = jsc_value_to_string (value);
