In my Rails app, I'm trying to hide a div (box) on page load in the Javascript function below. This function loops through a series of checkboxes with the same name (cb). If any of the checkboxes are checked, it should show the div.
function BoxCheck(cb,box){
var cbs=document.getElementsByName(cb);
var d=document.getElementById(box);
d.style.display = 'none';
var flag_check=0
for (var zxc0=0;zxc0<cbs.length;zxc0++){
if (cbs[zxc0].checked){
flag_check=flag_check+1
} else
{ }
}
if (flag_check > 0){
d.style.display = 'block';
document.getElementById('multi_control_spacer').style.display = 'block';
} else {
d.style.display = 'none';
document.getElementById('multi_control_spacer').style.display = 'none';
}
}
The function fires on load with:
<body onload="javascript:BoxCheck('doc_ids[]','multi_control');">
The problem is that when no checkboxes are selected, the div flashes on momentarily, and then disappears.
Here's the CSS:
#multi_control {
padding: 10px;
background: #333;
}
I tried setting the css to display:none, but then I can't seem to make it switch to back to display:block with Javascript.

Reset to default 8Why not? Have you tried:
element.style.display = 'block';
How about putting style="display:none" into the div tag so it's hidden to begin with?
