Question

我是公司的网站开发人员从本周开始，我和网络客户的所有同事都无法打开嵌入式pdf数据我们传输数据协议的方式，数据：application / pdf示例可以在plunker http://embed.plnkr.co/Bjkypkht4RjIWE1AyFP0/index.html中找到不久，我们将数据放入数据：application / pdf并使用window.open（）方法在浏览器中打开pdf二进制数据。
这个功能在本周之前正常工作，它实际上已经在IE / Firefox / Chrome浏览器中使用pdf附加组件或查看器插件工作了将近一年。

但本周开始，所有IE版本都不再起作用，错误显示如下，有谁可以帮我找出原因？

Error displayed by IE:
The webpage cannot be displayed
Most likely cause:
Some content or files on this webpage require a program that you don't have installed.

请不要告诉我重置IE或启用/禁用IE，所有这些方法都已经过我们的尝试但是没有用。感谢

这是我使用javascript验证的代码段。

            //create a Blob with an array and the optional dictionary object.
            var TEST_PDF_DATA = data;
            var byteCharacters = atob(TEST_PDF_DATA);

            var charCodeFromCharacter = function(c) { return c.charCodeAt(0); }
            var byteArrays = [];
            for (var offset = 0; offset < byteCharacters.length; offset += 1000)
            {
                var slice = byteCharacters.slice(offset, offset + 1000);
                var byteNumbers = Array.prototype.map.call(slice, charCodeFromCharacter);
                byteArrays.push(new Uint8Array(byteNumbers));
            }

            var blob1 = new Blob(
                byteArrays, //array
                { type: "application/pdf"} //dictionary object
            );

            //create a second blob that uses the first blob in its array
            var blob2 = new Blob([blob1, "Those who understand binary and those who don't."]);

            // Save the blob2 content to a file, giving both "Save" *and* "Open" options
            window.navigator.msSaveOrOpenBlob(blob2, 'msSaveBlobOrOpenBlob_testFile.pdf');
            alert('File saved using msSaveOrOpenBlob() - note the two "Open" and "Save" buttons below.');

最近在IE11 / 10/9上看不到PDF
