    Yes, but it does not work too.

    [ Qt ]
    webView = new QWebView;
    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget(webView);
    [ ... ]
    QWebElement el = webView->page()->mainFrame()->findFirstElement("#tool_open");
    el.evaluateJavaScript("this.click()");

    the click() action doesn't work

    With an another Qt code, I can call a Javascript function, but all actions (click, mouse events...) don't work :
    [ Javascript ]
    function test()
    {
    alert('clic');
    document.getElementById('tool_open').click();
    }

    I have Js pop-up "clic" but the click() action on the webelement 'tool_source' doesn't work...

      Does this return the exact element that you wanted ?
      You can just do

      qDebug() << el.toPlainText(); //prints the button text
      

      If this works then evaluateJavaScript should work too.

            qDebug() << "WebElement : " + el.attribute("type");

            it works, el.plainText does not work for this kind of webelement

            el.evaluateJavaScript("this.click()");

            it does not work

              It works too. It will print the list's text.
              Also for list click() works.
              What are you trying to do on click ? Can you post you HTML code which doesnot work ?

                I try to simulate a webelement click thanks Qt.

                In a web navigator the 'tool_open' click() opens an another web page (with javascript code...). I would like to do the same (simulate mouse clic) with Qt.

                [ HTML ]
                [ ... ]
                <ul>
                <li id="tool_clear">
                <div></div>
                Nouvelle Configuration
                </li>
                <li id="tool_open" >
                <div id="fileinputs">
                <div></div>
                </div>
                Open Image
                </li>
                </ul>
                [ ... ]

                  and yes the el.plainText works (I tried with an <input> HTML element instead of <li>...)

                    @fgdevel I dont see any code which gets invoked on click of tool_open. For eg . the following works i.e alert is called

                    <script>
                    function click(){
                               alert("Clicked");
                    }
                    </script>
                    <li id="list" onclick="click()">Clickable list</li>
                    

                    and from Qt

                    QWebElement b = ui->webView->page()->mainFrame()->findFirstElement("#list");
                    b.evaluateJavaScript("this.click()");

                      the action is realized by this function :
                      [ JS ]
                      var clickOpen = function() { [ ... ] }

                      but I don't know how to call this function in HTML, just clickOpen() doesn't work, even if I include the JS file in the HTML (<script src="myfile.js"></script>)

                        @fgdevel Well then you need to first figure out how to call that function on click of li element in HTML.

                          evaluateJavaScript is your friend

                          Exemple of code working with Jquery, replace with javascript code

                                          QString jsToExecute += "$('#login-btn').click(); ";
                                          ui->webView_login->page()->mainFrame()->documentElement().evaluateJavaScript(jsToExecute + "; null" );
