login.ejs contain following HTML

<h1>Log in</h1>
<div>
<label>Username:</label>
<input type="text" id="username" name="uname" /><br/>

</div>
<div>
<input type="submit" value="Submit"/>

and the code in .js file where I want to use that value is

if(username==teacher)
{
//some thing
}
else if(username==student)

//some thing
}

Answer 1

You can put this in the head of your ejs file, before loading the a.js file

 "<script > var username<%= title %> </script>"

This will define the variable username with the parameter passed to the ejs file, and you would be able to access it in any js file linked to the page
