JS Base64字符串可下载pdf - Edge [英] JS Base64 string to downloadable pdf - Edge

问题描述

我有一个问题，在所有浏览器和平台上，我可以使用以下命令将bse64字符串转换为PDF文件：

I have an issue at them moment, where in all browsers and platforms, I can convert a bse64 string to a PDF file using:

function runReport_onComplete(response)
{
    var element = document.createElement('a');
    element.setAttribute('href', encodeURI("data:application/pdf;base64," + response.Report));
    element.setAttribute('download', "LoginInquiry.pdf");
    element.style.display = 'none';
    document.body.appendChild(element);
    element.click();
    document.body.removeChild(element);
}

我做了一些研究，但我找不到解决办法我可以在其中指定文件名，并在Edge中自动下载文件。

I have done some research, but I have not been able to find a solution where I can specify the file name, and have the file download automatically in Edge.

提前感谢您的帮助。

推荐答案

如果我没记错，这是IE中的一般问题，而不仅仅是Edge。可以使用msSaveOrOpenBlob（）在IE中保存命名blob：

If I recall correctly, that is a general problem in IE and not just Edge. One can save named blobs in IE by using msSaveOrOpenBlob():

var tF = 'Whatever.pdf';
var tB = new Blob(..);

if(window.top.navigator.msSaveOrOpenBlob){
    //Store Blob in IE
    window.top.navigator.msSaveOrOpenBlob(tB, tF)
}
else{
    //Store Blob in others
    var tA = document.body.appendChild(document.createElement('a'));
    tA.href = URL.createObjectURL(tB);
    tA.download = tF;
    tA.style.display = 'none';
    tA.click();
    tA.parentNode.removeChild(tA)
}
