Run a bash script from HTML (Javascript function)

Question

I have a basic HTML file that takes inputs. I need to use those inputs to run a Bash file.

Right now I have:

function generate(){
 var arg=document.getElementById("site").value;
 RUN THE FILE WITH ./filename arg
}

Argument: <input type="text" id="arg" maxlength="3" size="3">
<br><input type="button" value="run file" onclick="generate()"> 

How can I run the bash file (./file arg)?
