var links = [
'https://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.exe',
'https://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.dmg',
'https://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.jar'
];

function downloadAll(urls) { var link = document.createElement('a');

url要设置成文件名

link.setAttribute('download', null); link.style.display = 'none';

document.body.appendChild(link);

for (var i = 0; i < urls.length; i++) { link.setAttribute('href', urls[i]); link.click(); }

document.body.removeChild(link); }

```html
<button onclick="downloadAll(window.links)">Test me!</button>
