static void web_view_javascript_finished (GObject object, GAsyncResult result, gpointer user_data) { WebKitJavascriptResult js_result; JSCValue value; GError *error = NULL;

js_result = webkit_web_view_run_javascript_finish (WEBKIT_WEB_VIEW (object), result, &error);
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)) {
    JSCException *exception;
    gchar        *str_value;

    str_value = jsc_value_to_string (value);
    exception = jsc_context_get_exception (jsc_value_get_context (value));
    if (exception)
        g_warning ("Error running javascript: %s", jsc_exception_get_message (exception));
    else
        g_print ("Script result: %s\n", str_value);
    g_free (str_value);
} else {
    g_warning ("Error running javascript: unexpected return value");
}
webkit_javascript_result_unref (js_result);

}

static void web_view_get_link_url (WebKitWebView web_view, const gchar link_id) { gchar *script;

script = g_strdup_printf ("window.document.getElementById('%s').href;", link_id);
webkit_web_view_run_javascript (web_view, script, NULL, web_view_javascript_finished, NULL);
