            Bug ID: 261043
           Summary: bug in documentation for
                    webkit_web_view_evaluate_javascript
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

The example in the documentation for webkit_web_view_evaluate_javascript at

https://webkitgtk.org/reference/webkit2gtk/stable/method.WebView.evaluate_javascript.html

is incorrect.

The statement "webkit_javascript_result_unref(js_result);" (see code fragment below) seems to be a holdover from the example for the deprecated Function webkit_web_view_run_javascript.
Therefore, it remains unclear how to correctly deal with the JSCValue "value" returned by the function webkit_web_view_evaluate_javascript_finish.

Code fragment from the documentation:

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

    value = webkit_web_view_evaluate_javascript_finish (WEBKIT_WEB_VIEW (object), result, &error);

    --- some lines of code removed ---

    webkit_javascript_result_unref (js_result);
}
