    Default QWebElement setAttribute not working as expected

    Not sure what is going on here. I'm loading some HTML in a QWebView and wanting to set the value of a <textarea> field.

    I already have a valid QWebElement reference to the element.

    Doing this does not work:
    QWebElement element = frame->findFirstElement("#myElement");
    element.setAttribute("value", "some value");
    qDebug() << "Attribute is:" << element.attribute("value"); // will output "some value"

    So the attribute is set, but visually the value of the text area is still blank.

    However this does work:
    QWebElement element = frame->findFirstElement("#myElement");
    element.evaluateJavascript("this.value='some value';");

    Now the textarea has "some value" in it as expected.

    Anyone know why the first method doesn't work?

    TEXTAREA doesn't use the value attribute of its tag (the syntax is <textarea>content</textarea>). Its javascript object indeed has a value property and that's what you should manipulate and that's what works as you noted yourself.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Oh yeah. Whoops. Makes sense, thanks.
