title: how to create an array in javascript which contains a set of arrays and assigning values to them dynamically?
body: <p>i want to create a web page using javascript and html, which takes details of many students from the user and dynamically store it into an array.
  so i guess what i need is an array of arrays which can be dynamically given values to.
  i created a page to get details of students like "first name". "last name", "admission number", and "class". i created a form and got the values like this.</p>
  
  <pre><code>form = document.std_form;
  f_name=form.firstname.value ; 
  l_name=form.lastname.value ;
  a_no=form.ad_number.value ;
  c_no=form.class_no.value ; 
  </code></pre>
  
  <p>f_name holds firstname and so on..
  now i want to create an array student_list which holds arrays std1, std2, std3 etc each which holds the details of separate students. pls tell me how to create such an array and also how i can display each elements.</p>
