Need Javascript To Show A Layer

Jul 20, 2005

Can someone help me figure out how to show a hidden layer *ONLY* if the
browser is IE for windows? I want it to remain hidden for everything else,
Netscape, Opera, Mozilla and anything for Mac. I'm not having much luck
out here.

Show Initial Layer

Feb 10, 2006

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">


#tabsB {
width:100%;
font-size:93%;
line-height:normal;

}
#tabsB ul {
margin:0;
padding:2px 10px 1px 0px;

Getting Onclick To Show Hidden Layer?

Mar 1, 2010

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.

Show/hide A Layer In A 5 Second Rotation?

Jan 30, 2009

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"

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?

Show Hide Layer In Firefox/mozilla??

Aug 6, 2005

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?

Show / Hide Div Layer / Change Link Color / When Radio Button Is Selected

Aug 16, 2010

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.

Floating Layer - While Scrolling - The Layer Flickers Continuously

Jan 30, 2009

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.

Getting Javascript To Show In My Browser

Sep 23, 2007

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>

Wanted: Workaround To Javascript:show(...); Instead Of OnClick ForNetscare 4

Jul 20, 2005

I was calling a function in a js file from an image onClick event, but
someone still using Netscape 4 (!) complained that it didn't work. I
read that img onClick doesn't work in Netscape 4, so swithced it to
"javascript:show(...);" and the code works, but I read in this group
that it was not wise to do that, here's the working version, using the
not recommended approach:

<a href="javascript:show('art_2.jpg',',^');" target="_self">

I'd appreciate any suggetions that will let me call the "show" function
from an onClick image event that will work in most IE/Netscape 4+ browsers.

Fading A Layer. Is This Possible?

Jul 23, 2005

I am trying to make a banner the size of the with of my screeen, in
a layer.

BUt I also want to fade it to a complete transperency to reveal the contents
of what's behind it (my page ofcourse) and possible close or hide the faded
layer.

I've seen stuff like that happen in a flash everonment. I was thinking about
using a transition at first to go from one page to another with an
introductory page.

But I rather have everything on one page and just fade the introdutory layer
into the page. Is that too much work for jscript?

NN 4.0+ I/layer Self-awareness

Jul 20, 2005

I have written a javascript routine that populates a parent document
with a series of <iframe>s. Each <iframe> receives its contents from a
series of separate smaller HTML files. Of course my NN 4.8 browser
doesn't deal well with the <iframe> so I wrapped the code that generates
the <iframe> in <ilayer> tags. NN now recognizes the contents.

However within each of the 'content' files I have another javascript
routine that basically displays the file name (via document.URL &
document.write) of the content file. My IE 5.5 & Mozilla 1.5
understands this perfectly. However my NN responds to the document.URL
with the wrapper/parent document's URL, not it's own unique file name.

I've named/ID'd the iframes & ilayers. If the document.URL fails I can
still make use of the ilayer ID but I need to know the index into the
layers array. I can hard-code a index value into the
document.layers[x].name but given that the position of the particular
content file is dynamic within the parent, the index is going to be
wrong 9 out of 10 times. There doesn't seem to any way for an i/layer
to know who it is Code:

Layer Transparent In Web Page

Sep 27, 2005

STYLE = "position: absolute;top:68px; left:563px;
width:640px;height:480px;">
<IMG src="ReportImageBox_12.54.52.png" width=640 height=480></IMG>
</DIV>

I need that the parts of this layer which have a certain color
(for instance "white") be rendered transparent.

My question. Is it possible to have a simple javascript function
to incorporate in the web page which does this?

Layer Ontop Of Frames

Feb 21, 2006

I was wondering if it was possible (and if so how) to put a layer ontop
of frames. What I mean is that I would be able to put anything,
including tables ontop of frames so that it could go ontop of two
frames at once, independent of everything else.

Also if it is possible, how would I make it stay still, evenwhen the
page is scrolled... like so that it doesn't even giggle or anything it
stays fixed..

Also, on another subject how would i make it appear next to the top
right hand corner of a cell in a table?
