The following function can download a txt file in other browsers, but jumps to a blank page in ie11. The file is URL-encoded and placed in the address bar. No download is triggered. How can I trigger downloading files in IE11?

Full project address: https://github.com/wangduandu...

this.downloadLog = function() { var file = "data:text/plain;charset=utf-8,"; var logFile = self.getLog(); var encoded = encodeURIComponent(logFile); file += encoded; var a = document.createElement('a'); a.href = file; a.target = '_blank'; a.download = self.formatTimestamp()+ '-' + self.logFilename; document.body.appendChild(a); a.click(); a.remove(); };

After checking the information, you can use Microsoft’s exclusive msSaveBlob. This method supports ie10 and above.

var downloadFileName = self.formatTimestamp()+ '-' + self.logFilename; if(window.navigator.msSaveBlob){ // for ie 10 and later try{ var blobObject = new Blob([self.output]); window.navigator.msSaveBlob(blobObject, downloadFileName); } catch(e){ console.log(e); } } else{ var file = "data:text/plain;charset=utf-8,"; var logFile = self.output; var encoded = encodeURIComponent(logFile); file += encoded; var a = document.createElement('a'); a.href = file; a.target = '_blank'; a.download = downloadFileName; document.body.appendChild(a); a.click(); a.remove(); }
