We Keep Coding

cannot download file from BlobUrl (using MediaReader)

I have the following code:
let self = this;
this.chunks = [];
const canvas2 = document.getElementById("self-canvas");
let recordStream = canvas2.captureStream(1);
var options;
options = {mimeType: 'video/webm; codecs=vp9'};
this.recorder = new MediaRecorder(recordStream, options);
this.recorder.ondataavailable = function(evt) {
self.chunks.push(evt.data);
};
this.recorder.onstop = function(evt) {
console.log("recorder stopping");
const link = document.createElement('a');
const videoBlob = new Blob(self.chunks, { type: "video/webm" });
console.log("file size: " + videoBlob.size);
const url = URL.createObjectURL(videoBlob);
link.href = url;
link.download = "sample.webm";
document.body.append(link);
link.click(); //if I comment out here I can see the video
};
console.log("finished setting controller")
console.log("recorder starting");
this.recorder.start(10000);
// the recorder.stop is called somewhere else
What it is supposed to do is pretty simple:
I have the element with id "self-canvas" that is showing my camera.
Now I am trying to record the camera and download the video from the browser using MediaRecorder, but for some reason I am unable to download the file.
I am sure that the file is being recorded, and console.log("file size: " + videoBlob.size); does not return empty.
But when I let the code run, instead of downloading the file, it tries to open it on the same window, and I cannot even see the video because the previous window disappears with the data of the recording.
However if I comment out the link.click(); I am able to see the video by opening the link on a new page (without closing the previous one). But it still doesn't download...
I used this as example, what am I doing wrong?

For heaven's sake...
I just added target blank and it worked.
link.href = url;
link.download = "sample.webm";
link.target = '_blank';
Probably because the resources are lost if it tries to open on the same page, and because it doesn't actually download the file if it is not a link "click".
Still, I never saw anyone having to add target blank in their examples like this one.
So I wonder why this is the case only for me...

Angular open a link always in a new tab Firefox

I have the following Angular code to download a PDF document. It works fine in other browsers but in Firefox when browser settings are set to "Open in Firefox" for PDF download then it doesn't open a new tab.
const blob = new Blob([data], { type: docType });
const blobDoc = window.URL.createObjectURL(blob);
const link = document.createElement('a');
link.href = blobDoc;
link.download = 'Filename.pdf';
link.click();
What I want is that in case of Firefox the link must always be open in a new tab. Even if when I set the target attribute, it doesn't open the new tab.
link.target = '_blank'
I tried the following and it works but then I do not get the file name.
const agent = window.navigator.userAgent.toLowerCase();
if (agent.indexOf('firefox') > -1) {
window.open(blobDoc, '_target');
} else {
// Normal download
}

Prevent OPEN file prompt in microsoft edge using angular js

I have a code in angular js which downloads an excel file on clicking a button. In chrome the file download starts automatically on clicking the button. But on Microsoft Edge clicking the button displays a prompt asking the user, whether they want to open or save file. Clicking on save button in prompt shows yet another prompt with 3 buttons OPEN, OPEN FOLDER and VIEW DOWNLOADS.
I know that edge provides settings options to disable the prompt on each download.
But is there any way on edge to start download but after downloading it does not show the second prompt asking what to do, using angular js or jquery?
The code for downloading file is as follows:
var fileName;
var a = document.createElement("a");
document.body.appendChild(a);
var type = headers('Content-Type');
var disposition = headers('Content-Disposition');
if (disposition) {
var match = disposition.match(/.*filename=\"?([^;\"]+)\"?.*/);
if (match[1])
fileName = match[1];
}
var blob = new Blob([data], {
type: type
}),
url = window.URL.createObjectURL(blob);
if (blob.size == 0) {
return;
}
a.href = url;
a.download = fileName;
var isIE = false || document.documentMode || /Edge/.test(navigator.userAgent); //if browser is IE and Edge
if (isIE) {
window.blur();
window.navigator.msSaveOrOpenBlob(blob, fileName);
} else {
a.style = "display: none";
a.click();
window.URL.revokeObjectURL(url);
}

Open Play Store on component load in Mobile Browser

I want to open Play Store on ngOnInit.
I have tried every combination but host name is added automatically.
myComponent.ts
var url1 = 'market.android.com/details?id=com.test&referrer=' + sponser;
window.open(url1, '_blank') //try1
$.get(url1, function () { /!*callback*!/
}); //try2
const link = document.createElement('a');
link.target = '_top';
link.href = url;
link.setAttribute('visibility', 'hidden');
link.click();//try3
But none of them are working. Thanks in advance.

window.open not working with Google Chrome?

I'm trying to open 2 pages with one click of a link, and this is what I have so far:
<a onclick="download()" href="?event=thanks&dl=<?php echo $_GET['dl']; ?>"><?php echo $linkname ?></a>
and the Javascript function:
function download() {
newwindow=window.open('http://www.google.com','download','height=200,width=150');
if (window.focus) {newwindow.focus()}
return false;
}
The code above works perfectly with FireFox and Safari, but it fails to open a new window with Google Chrome. Why is this? My thanks to anyone who can help.

<a> elements have a download attribute in HTML5 as explained here, with a default value of "" (an empty string).
This means that download === this.download in the onclick handler (this is the element in onevent attributes), and therefore the download attribute of the element is superior to the download property of window.
Oh, what a nightmare. Your function should not named download(). Change your function name to download1() and change your onclick to download1() too

You can use HTML5 download attribute.This attribute will tell browser that virtual link we created is aimed for download only. It will download file from links href to file with name specified as download attributes value. This feature works with Chrome.
Sample Code:
window.downloadFile = function(sUrl) {
//If in Chrome or Safari - download via virtual link click
if (window.downloadFile.isChrome || window.downloadFile.isSafari) {
//Creating new link node.
var link = document.createElement('a');
link.href = sUrl;
if (link.download !== undefined){
//Set HTML5 download attribute. This will prevent file from opening if supported.
var fileName = sUrl.substring(sUrl.lastIndexOf('/') + 1, sUrl.length);
link.download = fileName;
}
//Dispatching click event.
if (document.createEvent) {
var e = document.createEvent('MouseEvents');
e.initEvent('click' ,true ,true);
link.dispatchEvent(e);
return true;
}
}
// Force file download (whether supported by server).
var query = '?download';
window.open(sUrl + query);
}
window.downloadFile.isChrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
window.downloadFile.isSafari = navigator.userAgent.toLowerCase().indexOf('safari') > -1;
