I've got a web page which uses lots of divs to position the content of the
page and I'm using a nice javascript to alter the css of a table of links.
The thing is I don't want the table of links to point to an external site
but to calla function which will replace the content of a layer... perhaps
it's be better if I showed you the code:
This forum thread discusses the SitePoint article 'Re-Write a Layer's Content with Javascript' by Peter Todorov.
"How can you can replace the content of a Web page without additional requests to the server? The answer uses layers in JavaScript - Peter explains all."
I have this script running:
<html><head>
<script language="JavaScript" type="text/JavaScript">
var i=0;
function showcontent(){
document.all.myLayer.innerHTML+='Line '+i+'<br>'
i++;
setTimeout("showcontent()",200);
}
</script>
</head>
<body >
<div id="myLayer" style="position:absolute; left:20px; top:20px; width:300px; height:150px; z-index:1; overflow: auto;"></div>
</body></html>
As the function loops a new line is added to the contents of the layer. When the content is more than the height of the layer the scroll bars appear. This is fine, but what i want to be able to do is get the function to automatically scroll to the bottom of the content so the last line is always visible. Any ideas how i could do this?
Layer writing in Netscape. This is pretty straightforward >> However I'm trying to write to a <div> layer within a <div> layer.
My div:
Code:
<div id="blah">
<div id="aight">
</div>
</div>
I'm trying to write to "aight"
How should my code look?
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.

At some point while scrolling,the div 'movable' flickers continuously,while at some other point,it is perfectly stable.
I would like to load in content from an xml file, when the user clicks on one of the products from the sidemenu. The content will be an image and text for each type of headphone.I'm stuck on starting off, I'm not sure how to associate the click of one of the models with the correct model in the XML. In other words, in the JS how do I select the content for CX 300 in the same XML if they click on this model, I just need a little orientation please

<iframe src="http://www.page2.com" frameborder="no" width="410" height="600" name="worldFrame"></iframe>
and then change the visibility of elements on that page from my page?
I have a website with some navigation buttons on top. When one button is clicked I replace it's content with the content of a red button using this code:
document.getElementById('button').innerHTML = '
<a href="javascript:void(0)">
<img src="header/button_active.jpg" border="0" />
</a>'
The original code was enclosed in a DIV and I cant just change the img src because the original code is:
<div id="aanbiedingen">
<a href="javascript:void(0)">
<img src="1px_tranceparent.gif" name="Aanbiedingen" width="99px" height="20px" border="0" />
</a>
</div>
But when the orignal button is clicked, a ajax event goes off and loads the new page without reloading the button.
Using this code a button becomkes red once you click it. This is what I want.
Just one problem: when I click on another button, the first one stays red because it doesn't reload the page. Now I thought, I'll refresh the navigation page using a div and ajax. Code:

View 1 Replies View RelatedI've got a link that launches a little AJAX application in a window.
Like this:
function launchListener()
{
var newWindow = window.open("listener.php", "newWindow",
"width=300,height=150");
}
Ideally, once this window is loaded, it will sit in the background and
wait for stuff to happen. I would like to then change the title bar to
denote changes. Simple enough, right?
Anyway, problem is: When the new window launches, its title is not
exactly what I assign it in "listener.php" (for instance, "Listener"),
but rather "http://155.55.55.55 - Listener" (or whatever). This means
that while sitting the taskbar, generally all the user is going to see
is a domain name and some dots, rather than what I want them to see.
I have a div with a dynamic ID and content based on a database.I want to replace that ID's content with some content with I collect from the database via PHP.The new content may contain <br />'s.
View 1 Replies View RelatedI am running a website and I want to display many things on the same page. Currently what I have is something like this: [two buttons here][some code here, showing][some code here, hiding]When i click the second button, the hidden code replaces the code that was just showing. The first button then re-hides that code and shows the first code again. What I want to do is combine the two buttons so that when you click the first one, the text and hyperlink will change to display that of the second button. And when you click the button again, it will change to the text and hyperlink of the first button.

I've tested these in the following browsers:
Mac: Safari 3.2.1, Firefox 3.0.5
Windows: Firefox 2, Firefox 3.0.5, IE6, IE 7
These boxes work fine for me in all the browsers listed above, yet a friend using Windows can't get the drop downs working on either Firefox 3 or on IE 6.
I am using HTML/Javascipt/CSS to maintain a page whereby the content of the page is switched when a user selects a link. An example of the code used is below for your better understanding:
The container in which all of the content is loaded:
Code HTML4Strict:
<div id="container">
<div id="sub1"></div>
<div id="sub2" class="hide"></div>
[Code]....
I need the page to detect which "sub" is being displayed and change the style of that particular link so the user can see which is the active link.
For instance - When the page loads, by default, all subs are hidden except sub1 which is today's content - So when the page loads, I want the "Today" link to be styled differently to the rest... However, if they then go on to click "Tomorrow" - as well as changing the content like it already does, I need it to also switch the style of the link from the "Today" link to the "Tomorrow" link.
What website do any of you recommend for learning Javascript browser compatibility? I'd like to learn more about acceptable javascript programming.
I am using the script below for changing elements content without refreshing my page. Typically it works fine on recent Mozilla and IE releases if they haven't had too many hijacked settings. I know this isn't really much of an excuse for a script not to execute if it is done properly so I am hoping someone here can help me make what I have more compatible with more settings and browsers.

My application uses multiple lists in dynamic tables the contents of which change to reflext a user's context. I tried applying your tutorial code for assigning arrays to option values and text using the suggested pipe character "|" delimiter if one was used, but strangely in FireFox .search() to test for the presence of the pipe character returned 0 whether it was there or not! Using another character such as "#" worked fine. Also using DOM methods the text component had to be added by appending a TextNode otherwise the list simply displayed a list of 'undefined' items.My resulting function just unwraps an array of list items into an option group which is then appended to the select element at the calling end:[code]

View 9 Replies View RelatedI have a tab control finally behaving the way I want, with one exception. The second tab page contains a search form that returns data to be used in the first form on that page. The cgi program returns the results of the searh fine. The problem is that it when it returns the data, the tab control displays with the first page visible rather than the second. NB: I have not yet figured out how to add AJAX to the mix, but for now I just need a simple way for the search cgi program to tell the borwser that when it opens the page it produces, it should open with the second page visible Rather than the first.

View 4 Replies View RelatedI am trying to dynamically clear the value of a form input field and then submit the form.When I used $('#my_field').val('') to clear the field, it was cleared on the screen but when the form was submitted the original value of the input field was posted.My browser is FireFox and I can see using FireBug that when the field is cleared, firebug is still showing the html code with the old value. E.G. <input type="text" value="old_value" />The same situation occurred if I used $('#my_field').attr('value', '') to clear the field.The same situation occurred if I actually changed the value of the field rather than just clearing it.To work around this problem I ended up using the $('#my_field').removeAttr('value') to clear the field before it was submitted.
View 1 Replies View RelatedI 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?
I have a strange behaviour when applying onmouseout to a layer. it is
not trigged when the pointer goes out of the _layer_ but when it goes
off the _text within_ the layer.
I want to create a layer that 100% wide, 200 px high and stays at the
bottom of the screen, even when the page is scrolled, how do I do this?
I have seen it on websites but can't find any example code ...
Can someone please tell me how to print a single layer?
