Setting attribute in webpage and press button ‘GO’

[sujan.dasmahapatra]

I am developing a web application. I need to select an option from dropdown in a website and press ‘GO’ button.

I am connect with the website like as below.

QNetworkAccessManager *m_manager = new QNetworkAccessManager(this);
connect(m_manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*)));
m_manager->get(QNetworkRequest(QUrl("http://www.mysite.com/")));

m_WebPage = new QWebPage();
m_WebPage->setNetworkAccessManager(m_manager);
QString attr = m_WebPage->mainFrame()->documentElement().setAttribute("Diablo 3 (Diablo III)", "MySelection");
but with this my application crashing. Please tell me how can set an attribute in a webpage and press go. How can I get the attribute and the button ‘GO’ in my application.

Any suggestions is highly appreciated. Thanks Sujan

This line makes no sense and does not compile:

QString attr = m_WebPage->mainFrame()->documentElement().setAttribute("Diablo 3 (Diablo III)", "MySelection");

QString attr = m_WebPage->mainFrame()->documentElement().setAttribute("Diablo 3 (Diablo III)", "MySelection");

To copy to clipboard, switch view to plain text mode 

setAttribute() does not return a value (it's void). In any case, you are trying to set an attribute on a default, empty HTML document because you have not loaded anything into your QWebPage.

If you want to drive the web page as if a user were doing it then you need to:

• load the web page into the QWebPage,
• wait until loadFinished(),
• locate the element representing the drop down list
• change its value
• locate the element representing the submit button, and
• fake clicking it.

To select 2 options I do the following. And also click. But the values in my QWebView are not changing based on this. Please help whats wrong going on.

QWebElement selectBox =
m_WebView->page()->mainFrame()->findFirstElement("select[id=gameid]");

selectBox.setAttribute("value", "187");

QWebElement selectBox2 =
m_WebView->page()->mainFrame()->findFirstElement("select[id=hostid]");

selectBox2.setAttribute("value", "24351");


QWebElement button = m_WebView->page()->mainFrame()->documentElement().findFirst("input[type=button]");
button.evaluateJavaScript("this.click()");
