1、代码:

// ZC: 下面的 PatchElement()和PatchElementUn(),暂时是在 Release中使用,Debug中不确定一定OK... PatchElement(&eleFind); // ZC: 使用QWebElement::???Inside(...)的时候,就要对 那个节点 进行Patch ! ! ! eleFind.appendInside(str); PatchElementUn(&eleFind); PatchElement(&eleFind.parent()); // ZC: 使用QWebElement::???Outside(...)的时候,就要对 那个节点的父节点 进行Patch ! ! ! eleFind.appendOutside(str); PatchElementUn(&eleFind.parent()); } void MainWindow::on_pbtnPrintSvgContent_clicked() { qDebug() << ui->webView->page()->currentFrame()->toHtml(); }
