i want download file url

i using <a href="window.location.href='http://localhost:9999/file/bongda.png'">123123</a> or 

<a href="http://localhost:9999/file/bongda.png">123123</a>

but not success . please me ?

you've missed javascript: href:

<a href="javascript:window.location.href='http://localhost:9999/file/bongda.png'">123123</a>

if you'd force browser download file instead of opening it, following line should added backend code:

res.setheader('content-disposition', 'attachment; filename=' + filename);
