Javascript, programmatically trigger file download in firefox [closed]

Answer 1

I realize this is an old post, but I came across it when I had a similar problem downloading files in FF. This may not have worked in FF at the time the question was written, but it does now.

a = document.createElement('a');
document.body.appendChild(a);
a.download = name;
a.href = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAOCAYAAAAmL5yKAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAABWSURBVDhPY0xISPh//0UOA7mAiVyNMH2jBjAwkBQGjD9KGBTEJ6OEO0kG2NvbMwCjnXwDsEU5SS5ANuDhjRCGJbPFSQsDdBfIyMhQZgDIQLK9QLWkDABPsQw5I+5qmAAAAABJRU5ErkJggg==";
a.click();

Changes from the original fiddle:

1. Add call to document.body.appendChild(a);
2. Change triggerEvent() to a.click()
