推荐答案

您必须对QWebEnginePage进行子类化才能覆盖javaScriptConsoleMessage虚拟函数.( http://doc.qt.io/qt-5/qwebenginepage.html#javaScriptConsoleMessage )

You have to subclass QWebEnginePage to override javaScriptConsoleMessage virtual function. (http://doc.qt.io/qt-5/qwebenginepage.html#javaScriptConsoleMessage)

class CustomPage : public QWebEnginePage
{
public:
    CustomPage(QObject* parent = 0) : QWebEnginePage(parent) {}
    virtual void javaScriptConsoleMessage(JavaScriptConsoleMessageLevel level, const QString &message, int lineNumber, const QString &sourceID)
    {
        // Here goes your logging code
    }
};
