loading divs dynamically -- how to detect which one loaded currently..

[maya]

I'm using a function like this to load divs dynamically (and hide
current one..)

function get_img(curr_img,curr_nav,new_img,new_nav2) {
var img_top = eval('document.getElementById(' + "curr_img" + ')');
var img_new = eval('document.getElementById(' + "new_img" + ')');
var nav_top = eval('document.getElementById(' + "curr_nav" + ')');
var nav_new = eval('document.getElementById(' + "new_nav" + ')');
img_top.style.visibility = "hidden";
img_new.style.visibility = "visible";
nav_top.style.visibility = "hidden";
nav_new.style.visibility = "visible";
curr_img = new_img;
curr_nav = new_nav;
}

problem I always run into in situations like this is I can't tell which
one is currently loaded.. how do you detect which div is currently loaded?

this is in JSP, divs generated with loops...

for (int i = 0; i < photos.length; i++) {
%>
<div id="nav<%=photos%>">

etc...

thank you.............

Why are you evaluating instead of just doing

var img_top = document.getElementById(cur_img);

??????????

var img_new = eval('document.getElementById(' + "new_img" + ')');
var nav_top = eval('document.getElementById(' + "curr_nav" + ')');
var nav_new = eval('document.getElementById(' + "new_nav" + ')');
img_top.style.visibility = "hidden";
img_new.style.visibility = "visible";
nav_top.style.visibility = "hidden";
nav_new.style.visibility = "visible";
curr_img = new_img;
curr_nav = new_nav;
}

Not enough information here to have any clue what you mean.

%>
<div id="nav<%=photos%>">
