1. u js-u kreiraj Blob objekt koji sadrži podatke koje šalješ klijentu
var data = ['Vrijeme;ChargeCurrent;LoadCurrent;Voltage2013.01.178:34:28;0.24;0.28;13.152013.01.17 09:50:48;0.36;0.22;13.452013.01.17 11:15:54;0.39;0.33;13.69'];
var blob = new Blob([data], {type : 'text/csv'});
2. Kreiraj data uri do Blob objekta
var url = URL.createObjectURL(blob);
3. Kreiraj ili modificiraj anchor
var anchor = document.getElementById('a');
anchor.href = url;
anchor.download = '1.csv'; // Naziv i ekstenzija datoteke
Ovako izgleda finalni element
<a id="a" href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO 9TXL0Y4OHwAAAABJRU5ErkJggg==" download="red_dot.png">Download red dot</a>
