Accessing Controls From JavaScript

What is the syntax for accessing control form javascript? I can't seem to find it anywhere - I thought it was something like

dunction HideOne(n)

{

var ele = Sys($(n))

}

not a lot to go on with what you have provided but...

assuming that "n" in this context is the id of an element you want to "access" or get then you should use "$(n)"
to avoid issues with that statement... in your example you would remove the Sys() part and only have the $(n) part

this all depends on, however, how you are creating your elements. if you are using the xml-script declarative approach then you might be better off using the $object() function.
the $object() function searches the current markup context for the element, then traverses the tree up to the Application level to try to find the element.
this is different than the $() function which is nothing more than a shortcut for "document.getElementById()"

this allows the ATLAS runtime to have (or support) multiple elements with the same "id" without violating the HTML 4.1 specifications stating "an elements id must be unique" which it clearly would be (in the current context)

hope that helps... if not try adding some more of your code so we can get a better understanding of what you are dealing with

That was perfect thanks.
