创建blob期间Internet Explorer 11中的InvalidStateError [英] InvalidStateError in internet explorer 11 during blob creation

问题描述

我在blob创建行上得到一个InvalidStateError即11。不用说，它适用于Chrome和Firefox。
我可以看到二进制数据是我的客户端。有没有其他方法可以将其下载为文件？

I'm getting an InvalidStateError at the blob creation line on ie 11. Needless to say, It works in Chrome and Firefox. I can see that the binary data is my client side. Are there any alternatives to download this as a file?

var request= new ActiveXObject("MicrosoftXMLHTTP");
request.open("post", strURL, true);
request.setRequestHeader("Content-type","text/html");
addSecureTokenHeader(request);
request.responseType = 'blob';


request.onload  = function(event) {
if (request.status == 200) {
var blob = new Blob([request.response], {type: 'application/pdf'});
var url = URL.createObjectURL(blob);

var link = document.querySelector('#sim');
link.setAttribute('href', url);
var filename =  request.getResponseHeader('Content-Disposition');
$('#sim').attr("download", filename);
$(link).trigger('click');
fireEvent(link,'click');

}else {
//handle error
}
}

推荐答案

在实例化XmlHttpRequest对象后立即通过设置xhr.responseType =blob获取InvalidStateError后，移动

After getting InvalidStateError by setting xhr.responseType = "blob" right after instantiating the XmlHttpRequest object, moving

xhr.responseType = "blob" 

to

xhr.onloadstart = function(ev) {
    xhr.responseType = "blob";
}

为我解决了！ ：）
