如何在新窗口打开pdf文件，并修改网页标题

一、使用iframe打开

newWindow.document.title = "新页面标题";
const iframe = newWindow.document.createElement('aaa')
iframe.src = url; // 你想要加载的URL
iframe.width = '100%';
iframe.height = '100%';
newWindow.document.body.appendChild(iframe);

二、使用embed标签

 const blob = new Blob([res.data], { type: 'application/pdf' })
 const url = URL.createObjectURL(blob)
 const newWindow = window.open('', '_blank')
 if (newWindow) {
      newWindow.document.write(`
          <html>
            <head>
              <title>考核比例参照表</title>
            </head>
            <body>
              <embed src="${url}" type="application/pdf" width="100%" height="100%">
            </body>
          </html>
        `)
  newWindow.document.close()
