在IE9中使用JS下载PDF作为Blob [英] Downloading PDF as Blob with JS in IE9

问题描述

我有一个blob并想下载它。它适用于Chrome，Firefox，IE10及更高版本。问题是IE9。

I have a blob and want to download it. It works for Chrome, Firefox, IE10 and higher. The problem is IE9.

                    var isIE = /*@cc_on!@*/false || !!document.documentMode;  
                    var blob = new Blob([data], {type: "application/pdf"});
                    if (isIE) {
                        window.navigator.msSaveOrOpenBlob(blob, "Download.pdf");
                    } else {
                        var link = document.createElement('a');
                        link.href = window.URL.createObjectURL(blob);
                        link.download = "Download.pdf";
                        link.id = "TEST";
                        $('body').append(link);
                        document.getElementById("TEST").click();
                    }

问题出在哪里？ IE在URL中具有2.083作为字符的最大限制。也许这很关键。我有什么替代品？我必须支持IE9 ...谢谢。

Where is the problem? The IE has 2.083 as maximal limit for chars in URL. Maybe this is critical. What alternatives do I have? I have to support IE9... Thanks.

推荐答案

您可以阅读这里从IE版本10支持Blob构造函数。您可能想要使用 PDF.js 。

As you can read here the Blob constructor is supported from IE version 10. You may want to use PDF.js.
