Using the browser event OnLoadDone()
{
WebWin=EOWeb.GetDOMWindow();
WebDoc=WebWin.docouement; ParsePg();
}

void ParsePg()
{
...
EO.WebBrowser.DOM.Element e = WebDoc.getElementById("someID");
...
}

The above line crashes when F5 is pressed with error
EO.WebBrowser.JSInvokeException: 'Invoking function 'getElementById' failed because object is invalid.'

How can prevent or what should be check when parsing the page?

Hi,

Sorry about the delay. Somehow we missed this post.

The error message indicates that the document object no longer exists. This can happen if your page immediately redirect to a different page after it has finished loading. If this is not the case, please try to isolate the problem into a test project and send the test project to us. Once we have that we will investigate further. See here for more information about sending test project to us:

Also how did you connect F5 to your OnLoadDone event handler? I understand that F5 triggers a refresh, but it does not directly trigger any of EO.WebBrowser's event.

Thanks
