How to create dynamic function in javascript?

Help with writing JavaScript code in notepad?

How do i create an html document with a function in the head section named printPersonalInfo(), and within this function use the document.write() and document.writeIn() methods to print my name,adress,date of birth, and social security number on the screen. I need to call the function from the body section of the document. Can someone please help! CODE SO FAR BUT DOSEN"T WORK! <html><head> <title>Print Personal Info Function</title> <script language="JavaScript">  </script></head><body> <script language="JavaScript">  </script></head></body></html>
Answer:

First, that's the document.writeln() method (with a lower-case L in the name where you have a capital I). I found that by copying your code, saving it as an HTML file, and running it. If you fix that, you'll find that it will write the "John Doe" and that's all. The reason is that you have four separate parameters in the call to your function, and only one argument defined. That argument, personal_info, is matched to the first parameter in the call, and that's all that's written. Change the function to function print_personal_info(name, hometown, birthdate, ssn) { document.writeln(name, hometown, birthdate, ssn); } and it works. (Of course, the fields are all run together, because no spacing was specified.) Now change the .writeln() call to document.writeln(name, '<br>', hometown, '<br>', birthdate, '<br>', ssn); and each field will appear on a separate line.
