Show/hide Layer Dependent On Browser
Jun 17, 2005
I'm using the scroll function with a layer containing a graphic that sits over the slider on the y axis. This works fine in IE but overhangs the lower scrollbar arrow in Netscape, Firefox and Opera, killing its functionality, so I'd like to hide it in these browsers.
Could someone show me the best way to work a function that says (taking the layer ID as 'Bar')
IF browser = IE
THEN 'Bar' = visible
or (better?)
IF browser <> IE
THEN 'Bar' = hidden
And how should I allow this to behave in Safari?

I'm looking to show/hide a layer in a 5 second rotation.
IE: For 5 seconds the layer is shown, then the next 5 seconds it is hidden, the next 5 seconds it is shown, the next 5 seconds it is hidden... {ad nauseum} - you get the idea.
How could I accomplish this with JavaScript? The layer id="overlay"

Found a simple script to show and hide layers. Using this to have an ad with 60px height and onMouseOver 350px
function adtechhideElement(elmID)
{
for (i = 0; i < document.all.tags(elmID).length; i++)
{
obj = document.all.tags(elmID)[i];
if (! obj || ! obj.offsetParent) continue;
obj.style.visibility = "hidden";
}
}
function adtechshowElement(elmID)
{
for (i = 0; i < document.all.tags(elmID).length; i++)
{
obj = document.all.tags(elmID)[i];
if (! obj || ! obj.offsetParent) continue;
obj.style.visibility = "";
}
}
but the thing is this doesn't work in firefox/mozilla.
Where should I alter this to get it working in firefox?

I am trying to develop an exam system.Find my code below.I request you to copy the code and save it as an html file .I have 2 problems:
1. Kindly notice that when the quiz is loaded,it shows both the questions by default.I want only question 1 to be visible when the quiz loads.What happens presently is that ,both questions are visible even after I click on the link
Q.1( referring to question 1).However,when I click on
Q. 2,then only question 2 can be seen and then(after clicking on Q.2) if I click on Q.1,then only question 1 can be seen
What I want is that when the page loads only question 1 is visible.Then when I click on Q.2,I can see only question 2 and when I click on Q.1, I can see only question 1.I later plan on adding many questions,so it should be a general solution rather than a solution good only for 2 questions.
2.Also,what I want is that,if someone selects any of the answers of a particular question,it's link color should turn green to indicate to the user that he answered that question.So for,instance,if I select an answer to the first question(select one of London,New York,Seattle,Washington,Chicago), the link Q.1 should turn green.

Since the code is triggered ever onclick event it may be resource hungry on large pages.
I guess desired upgrades to suit it more for general purpose and reuse would be:
1> Replace document.write with a way of altering the CSS class rule property. Hard part on this after reading quirksmode would be in targeting the CSS rule in a cross browser, not to intensive way.
2> Find a better cross browser trigger attachment than the current firing on every click.

I built a dynamic ajax suggest engine, and you would think I could
figure this out, but I am having a brain cramp. When I don't have any
characters in the search box, it shows a little blip of the layer
where the suggestion results go...
How do I make this go away? Something along the lines of
if ( document.getElementById('txtSearch').length == 0){
thelayer.style.display=(thelayer.style.display=="none");
}???

I am using CSS text-shadow but of course IE doesn't like it. I've looked into some methods for achieving the same effect in IE, but it's not at all the same so I've opted for another method..I'm going to have two layers. In layer1, it will be standard text, shadowed with CSS. I then screenshotted that and will use the resulting jpeg for layer2.I was then planning to find a script that:1. Detects if browser is IE2. If IE, layer2 is visible, layer1 is invisible3. If not IE, layer1 is visible, layer2 is invisibleThe problem is that I can't find a simple script to detect if the browser's IE or not. I can find loads of scripts that check what version of IE someone's using. The version isn't important!

Below code creates a tabbed navigation. Works well. But how do I set it up so Tab 1 shows when the page is loaded?
Code:
<script type="text/javascript">
function initShowHide() {
if (document.getElementById && document.getElementsByTagName && document.createTextNode) {
hide();
var toggle = document.getElementById('toggle');
var as = toggle.getElementsByTagName('a');
for (var i = 0; i < as.length; i++) {
as[i].onclick = function() {
show(this);
return false;
}
}
}
}
function show(s) {
hide();
var id = s.href.match(/#(w.+)/)[1];
document.getElementById(id).style.display = 'block'
}
function hide() {
var toggleable = document.getElementById('toggleable').getElementsByTagName('div');
for (var i = 0; i < toggleable.length; i++) {
toggleable[i].style.display = 'none'
}
}
window.onload = initShowHide;
</script>
<style type="text/css">

I want the hidden layer to open when the visitor clicks and stay open until they click the close x. I can get the hidden layer to show onMouseover, but not onclick.
Code:
<script type="text/javascript"> // Copyright 2006-2007 javascript-array.com var timeout= 500; var closetimer= 0; var ddmenuitem= 0; // open hidden layer function mopen(id) { // get new layer and show it ddmenuitem = document.getElementById(id);
[Code]....
I find script that does something similar and adapt it to do what I need it to do. Usually, I can work it out on my own - but I have been working on this for several days now.

I have created a floating layer using Javascript that remains always on top of page on scrolling.Issue is,at some point while scrolling,the layer flickers continuously.
The html page is as follows:
Many common software systems, JavaScript has a history of security problems. Many of these problems could allow a person with malevolent intent to steal sensitive information from a visitor. The number and type of such holes in security vary among browsers and operating system versions. Most JavaScript security holes have been caught and fixed, but new ones are being discovered all the time. For a list of current security holes check out your browser's and operating system's Web pages. As a Web site author, it is your responsibility to keep up-to-date on the current status of known security holes in the applications you create.
Signing Scripts. In Chapter 11, I explained that JavaScript does not provide the ability to directly access files on the client computer. This can be a very large hurdle to overcome if you're trying to upload a file to a server from the client computer. Fortunately, file uploading is one of many functional enhancements that signed scripts provide. Signed scripts are specially packaged scripts that have been verified and signed to be correct and non-threatening. These scripts have additional rights on the client computer that allow a programmer to do many things that he wouldn't otherwise be able to.
With the introduction of Netscape 4.0, a new security model was put in place that would allow digitally signed scripts to bypass some of the restrictions that had previously been placed on them. A signed script can request expanded privileges from the visitor and, with the visitor's permission, gain access to restricted data. A signed script requests these additional permissions through LiveConnect, which allows your JavaScript code to communicate with the Java Capabilities API. The security model allows JavaScript to access certain classes in Java in order to extend its functionality while still maintaining tight security for the client.
A digital signature is a fingerprint of the original programmer, and it allows the security model of the browser to detect where (or from whom) it originated. A script signer can be a person or an organization. By signing a script, you acknowledge yourself as the author and accept responsibility for the program's actions. A signed script contains a cryptographic checksum, which is just a special value that ensures the signed script has not been changed. When a digital signature is detected, you are assured that the code has not been tampered with since the programmer signed it.
Once you finish writing a script, you can use the Netscape Signing Tool to digitally sign it. Signing a script does the following:
Unambiguously assigns ownership of the script to a person or organization.
Allows an HTML page to use multiple signed scripts.
Places the signed script into a Java Archive (JAR) file.
Places the source of the script in the JAR file.
Once a user confirms the origin of the script and is assured that it has not been tampered with since its signing, he or she can then decide whether to grant the privileges requested by the script based on the validated identity of the certificate owner and validated integrity of the script.
JAVASCRIPT FILE IS AS FOLLOWS:
AND CSS FILE IS AS FOLLOWS:
At some point while scrolling,the div 'movable' flickers continuously,while at some other point,it is perfectly stable.

I know how to click a link to show a hidden div. However, how can I hide the div when users click anywhere in the browser? I would like some behaviour like "releaseOutside" in javascript.
I search this forum and find some code to try, but it doesn't work. When I click the link, the div does not show anymore (if I took out the document.onclick function, the div shows). Here is my code:
<script language="javascript" type="text/javascript">
function showdiv() {
document.getElementById("mydiv").style.display = "block";
return false;
}
document.onclick = function() {
document.getElementById("mydiv").style.display = "none";
}
</script>
</head>
<body>
<a href="#" onclick="return showdiv()">Link</a>
<div id="mydiv" style="display:none">bah bah bah...</div>

In my course on website design we just started some JavaScript. In the very first assignment nothing shows in my browser. I have two questions:
Is there a way to get it to show in my browser so I can complete the assignment?
Is JavaScript widely unviewable? Here is the script I used:
<script language="JavaScript">
<!Hide from non-JavaScript browsers
document.write("Today is 12/15/2003<br>");
document.write("Only 10 days until Christmas");
//Stop hiding -->
</script>
