instead of    x000D   x000D  document getElementById  txtBillingGroupName   value   groupName  x000D   x000D   x000D    You can use    x000D   x000D      txtBillingGroupName   val groupName   x000D   x000D   x000D    instead of groupName you can pass string value like  Group1

Pass the variable to the form element like this  your form element   lt input type  text  id  mytext  gt    javascript  var test    Hello   document getElementById  mytext   value   test   Now you get the js variable inside your form element

You could also use to localStorage feature of HTML5 to store your test value and then access it at any other point in your website by using the localStorage getItem   method   To see how this works you should look at the w3schools explanation or the explanation from the Opera Developer website   Hope this helps

This was a problem for me  too  One reason for doing this  in my case  was that I needed to convert a client-side event  a javascript variable being modified  to a server-side variable  for that variable to be used in php   Hence populating a form with a javascript variable  eg a sessionStorage key value  and converting it to a   POST variable    lt form name  formName  gt   lt input name  inputName  gt   lt  form gt    lt script gt  document formName inputName value var  lt  script gt
