GetElementById And Visibility Issue

May 10, 2005

I am trying to loop through the ID's from the DIV's to toggle visibility on and off. The first time through my loop the visibility property returns null. Is there a known issue with Javascript and the visibility property?

The code is like this:
for(i = 1; i <= 3; i++)
{
if (document.getElementById('t' + i).style.visibility == 'visible')
{
document.getElementById('t' + i).style.visibility = 'hidden'
}

<STYLE TYPE="text/css">
<!--
#t1
{
position: absolute;left: 100px; top: 80px; height: 400px; width: 100px; z-index:1; visibility:visible; }

#t2
{
position: absolute;left: 100px; top: 80px; height: 400px; width: 100px; z-index:2; visibility:hidden; }

#t3
{
position: absolute;left: 100px; top: 80px; height: 400px; width: 100px; z-index:3; visibility:hidden; }
-->
</STYLE>

</head>
<body>
<form>
<div id="t1">Testimonial 1</div>
<div id="t2">Testimonial 2</div>
<div id="t3">Testimonial 3</div>

Element.getElementById Instead Of Document.getElementById

May 13, 2004

I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.

In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.

GetElementById Element Null - Error Stating "getElementById("ballElement") Is Null

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

Image Visibility In IE

Jul 20, 2005

I am trying to set up a page where there are a couple of checkboxes, and
based on the selected checkbox, certain input fields are required. For the
required fields, I want to display a red asterick as an image (
required.jpg ) next to the field iteslf. Thus, I am trying to write a
JavaScript function that will get called via the "onchange" action for each
checkbox.... this function willl either set the visibility to "visible" or
"hidden" for the red asterick ( required.jpg ) next to each input ( name,
address, email, etc... ). I am able to get this working in Netscape (
7.02 ), however I can't seem to get it to work for Internet Explorer (
6.02 ).

Here is a trimmed down, working ( at least in Netscape ) sample of what I am
trying to do. Any idea on what I need to do differently to get this to work
in IE? Code:

Changing Visibility Of DIV

Aug 18, 2006

I would like to change the visibility of the contents of a DIV by clicking a button or link. If possible, I'd like the button to toggle the visibility on/off. If not, I'll just have two buttons, one to make it visible, the other to hide it.

Also, I'd like the page content under the DIV to move up/down as the DIV is hidden/visible (as if the text inside the DIV did not exist when the it was hidden).

The code I tried before posting was this:
function visibility(id){
document.getElementById(id).style.visibility=hidden;
}
I couldn't find any documentation on the Visibility property, so I didn't know how to use it correctly. Also if there is a better way to achieve the effect I want than using style.visibility, please post it.

Changing DIV Visibility

Jun 19, 2006

I want to add a caption to certain images on a website I'm building when the user moves their mouse over it, along the lines of "Click to Enlarge". The HTML code I've got is as follows:

<div class="overlay">
<a href="#"><img src="image/example-4.jpg" alt="Example Image" /></a>
<div><p>Click to enlarge image</p></div>
</div>
The DIV with the caption is set in the CSS to display:none; and I have the following JavaScript code which is supposed to change this property to block on hover:

window.onload = function(){
var overlay = document.getElementsByTagName('div');
for(var i=0; i<overlay.length; i++){
if(overlay[i].className == 'overlay') {
overlay[i].onmouseover = function() { this.getElementsByTagName('div').style.display = 'block' }
} } }

But this gives this error:

Error: this.getElementsByTagName("div").style has no properties
Any idea what I've done wrong?

Turn Visibility On And Off?

Jul 8, 2011

I have a web page that has javascript running an html5 page where as the embedded movie plays, the captions play below the movie. What I'd like to do is to have a button that turns the captions' visibility on and off, but I can't seem to get it to work. Probably easier to just show you the web page so you can see the files and view source: [URL] Click the test.html file and hit the play button for the movies to see the captions. I think it might have something to do with the captions being within the media div, but I'm not sure how to address the caption id other than the way I have.

Element Visibility During Scrolling

Nov 23, 2005

I'm trying to figure out which elements of a document are visible as the user scrolls the Firefox browser. I haven't written the code yet but I think I should be able to do it by keeping track of the current display using the following properties:

window.content.scrollX, window.content.scrollY,
window.content.innerWidth, window.content.innerHeight. -- with these 4
I can determine which part of the document is visible.

Then for each element I can figure out its display position using, offsetWidth, offsetHeight, offsetTop, offsetLeft. This would entail traversing the DOM and perculating the offset values down to all the children.

While this would likely work, it seems inefficient. Do you know of any other ways to determine which elements are actually on the screen?

Toggle DIV Visibility After Link Followed

Oct 29, 2011

I've got a script that toggles the visibility of a div on "dashboard.html":
$(document).ready(function(){
$("#add_networks_wrapper, .remove_box").hide();
$(".toggle_add_networks").show();
$('.toggle_add_networks').click(function(){
$("#add_networks_wrapper, .remove_box").slideToggle();
});
});
On "dashboard.html" it works great. The div "add_networks_wrapper" is hidden until I click the link that toggles it. What I need is a link from a different html page (say "account.html" or whatever) to open "dashboard.html" with the hidden div's visible.

Opera Function Visibility Oddity

Jul 23, 2005

Opera seems to have different ideas about the visibility of Javascript
functions than other browsers. For example, if I have this code:

if (1==2) {
function invisible() {
alert("invisible() called");
}
}

then most browsers will consider invisible() to be undefined. But in
Opera you can call it! You can try this online here: Code:

-> Style.visibility Not Working In IExplorer ??? <-

Dec 5, 2006

I have a strange problem using Internet Explorer.
My page has a table included in a <DIV>
I have a checkbox that shows the div when checked
and hides it when unchecked.

var division = document.getElementById("passport") ;

Then I use
division.style.visibility = "visible" ;
or
division.style.visibility = "hidden" ;

Everything works perfectly under FireFox or Safari showing or
hidding the table.

BUT, in IExplorer 6 or 7, just checking the checkbox doesn't
change anything. You have to first click on the actual division
position to make it appear. Same for unchecking: click on the
displayed table and it will disappear. Code:

Set Element Visibility Using Switch/Case?

Nov 19, 2010

So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items.

This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail.

The Code (class references are irrelevant to this example, they belong to the final project):

<html>
<head>
<script type="text/javascript" language="JavaScript">
/*
