WebKit2.WebView.prototype.run_javascript_finish

function run_javascript_finish(result: Gio.AsyncResult): WebKit2.JavascriptResult {
    // Gjs wrapper for webkit_web_view_run_javascript_finish()
}
  

Finish an asynchronous operation started with WebKit2.WebView.prototype.run_javascript.

This is an example of using WebKit2.WebView.prototype.run_javascript with a script returning a string:

<informalexample><programlisting> static void web_view_javascript_finished (GObject *object, GAsyncResult *result, gpointer user_data) { WebKitJavascriptResult *js_result; JSValueRef value; JSGlobalContextRef context; 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; }

context = webkit_javascript_result_get_global_context (js_result); value = webkit_javascript_result_get_value (js_result); if (JSValueIsString (context, value)) { JSStringRef js_str_value; gchar *str_value; gsize str_length;

js_str_value = JSValueToStringCopy (context, value, NULL); str_length = JSStringGetMaximumUTF8CStringSize (js_str_value); str_value = (gchar *)g_malloc (str_length); JSStringGetUTF8CString (js_str_value, str_value, str_length); JSStringRelease (js_str_value); 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); g_free (script); } </programlisting></informalexample>
