Window.open二进制数据pdf正在下载但不显示pdf：Javascript

Question

我有pdf的base64二进制数据，我试图在新窗口中打开， 它正在下载但没有打开，新窗口为空，空白

<a click="openfile(sampledoc)"  href="#"><img src="some.png" /></a>

function openfile(binaryData){
 window.open('data:application/pdf;base64,'+binaryData, 'samplepdf', 'width=700px,height=600px');
}

Pdf正在下载完美，但它没有显示在打开的窗口中。

Pdf在firefox的新标签页中显示，但在chrome中显示下载但未显示

Answer 1

我在firefox和chrome上试过这个，它是在新窗口中打开而不是下载。

可能与您计算机上的Chrome设置有关。请从另一台机器上试试。

在浏览器上打开/打印pdf是有问题的。有些浏览器使用adobe插件打开，有些使用pdf.js，有些使用其他方法，有些使用下载而不是打开。
