QWebEngineView runJavaScript() problem
Unsolved
QtWebEngine
-
Hello all.
I faced with some strange behavior in QWebEngineView.
I have a loaded page in QWebEngineView object witch has 'group0' element.
I run next script:... QString script = "document.getElementsByName('group0');"; page()->runJavaScript(script, [](const QVariant &v) {qDebug() << v;}); ...
It prints
QVariant(QVariantMap, QMap())
But now I need value of first element of 'group0' (or array with several values). I tried to run script:
QString script = "var elems=document.getElementsByName('group0');" "system.log(elems[0].value);"; page()->runJavaScript(script, [](const QVariant &v) {qDebug() << v;});
But I got
QVariant(Invalid)
Documentation says
Runs the JavaScript code contained in scriptSource. When the script has been executed, resultCallback is called with the result of the last executed statement. Note: resultCallback can be any of a function pointer, a functor or a lambda, and it is expected to take a QVariant parameter.
Could you say me how can I return result of the last executed statement from script to callback.
Thank you.
