Considering you use jQuery, you can write something like this:

$("#contentdiv>div").each(function(e) {
    if ($(e).attr("name") == "toShow") $(e).show("fast");
    else $(e).hide("fast");
})

It is quite hard to understand what you want to achieve, but I assume you want to be able to specify a name of the div, show this div, and hide all the others.

This could be done like that:

function showdiv(toshow){
    $("#contentdiv > div").hide("fast"); //Hide all divs
    $("#" + toshow).show("fast"); //Show one specific div
}

Then you can run the function like that:

showdiv("div1"); //Hides all divs, only shows the one with id 'div1'

Also, you don't need to write:

$(document.getElementById("div1"));

To get a jquery element by id, you just have to specify that you're picking the element by its id by writing # before the name. Do it like that:

$("#div1")
