Answer 1

function WriteToFile(passForm) {
    set fso = CreateObject("Scripting.FileSystemObject");     
    set s   = fso.CreateTextFile("<your Path>/filename.txt", True);
    var firstName = document.getElementById('FirstName');
    var lastName  = document.getElementById('lastName');
    s.writeline("First Name :" + FirstName);
    s.writeline("Last Name :" + lastName); 
    s.Close();
 }

<form onSubmit="WriteToFile(this)">
<label>Type your first name:</label>
<input type="text" name="FirstName" id="firstName" size="20">
 
<label>Type your last name: </abel>
<input type="text" name="LastName" id="lastName" size="20">
 
<input type="submit" value="submit">
</form>
