1、QT QWebengine運行JavaScript獲取圖片的數量
pView->page()->runJavaScript("document.getElementsByTagName(\"img\").length", []
(QVariant result) {
qDebug() << result.toString();
});或者
struct GetElementCountFunctor {
GetElementCountFunctor(){ }
void operator()(const QVariant &result) {
qDebug() << result.toString();
}
};
pView->page()->runJavaScript("document.getElementsByTagName(\"img\").length", GetElementCountFunctor());
