有没有办法将Pdf放入Swal模型中?

您可以在SweetAlert中添加一些html代码。

Swal.fire({
  title: '<strong>HTML <u>example</u></strong>',
  icon: 'info',
  html:
    'You can use <b>bold text</b>, ' +
    '<a href="//sweetalert2.github.io">links</a> ' +
    'and other HTML tags',
  showCloseButton: true,
  showCancelButton: true,
  focusConfirm: false,
  confirmButtonText:
    '<i class="fa fa-thumbs-up"></i> Great!',
  confirmButtonAriaLabel: 'Thumbs up, great!',
  cancelButtonText:
    '<i class="fa fa-thumbs-down"></i>',
  cancelButtonAriaLabel: 'Thumbs down'
})

然后尝试添加带有嵌入的pdf,例如:

<embed src="files/Brochure.pdf" type="application/pdf" width="100%" height="600px" />
