QwebEngineView运行javascript的问题，使用pdfobject显示PDF

gucunlin 2019-10-21 06:21:52

使用了 setUrl Load方法没一点反应，显示的是本地html html同级有js文件夹，里面是PDFObject.main.js显示pdf
使用sethtml调试输出有显示，最后卡在 PDFObject未定义的问题上，解决不了。网页用chrome打开能正常显示pdf



<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title>在线浏览PDF</title>

    </head>

    

    <body>

    

        <script type="text/javascript" src="js/pdfobject.min.js"></script>

        <script>

            PDFObject.embed("D:/visual3D/WorkstationMultiuser/Builder/Debug/report/Data/1.2.840.113704.1.111.5488.1521071043.1/2019-10-11_15-45.pdf");

        </script>

    </body>

</html>

pdf绝对路径，相对路径都试了
调用代码



ui->webEngineView->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);

QString path = "D:/visual3D/WorkstationMultiuser/Builder/Debug/report/Data/view.html";

	//ui->webEngineView->load(QUrl(path));

	//return;



	QFile file(path);

	bool isok = file.open(QIODevice::Text | QIODevice::ReadOnly);

	QByteArray htmldata = file.readAll();

	file.close();

	QString ans = QString(htmldata).toUtf8();

	ui->webEngineView->setHtml(ans);

报错信息

使用sethtml以exe为当前目录
