JavaScript - Need Help For Javascript Doubt

Hi All,

I am facing a problem with popup windows.

I have taken two Global variables

var popupWindow=null;
var popups = new Array();

In a function I am opening number of popup windows on click of a button and putting object of all the popups into an Array.

popupWindow = window.open(url,'WinName','resizable=yes,scrollbars=1,status=yes,alwaysRaised=yes,width=750px,height =500px');
popups.push(popupWindow);

I am using this Array to perform different operations like changes colors of popups and main window. But when I refresh the page all the object get lost is there any why to retain these object. We have a restriction that we can't use Frames.

If anybody have an idea Please share with me. Thanks In advance.

i'm using a JavaScript typing tutorial....here is my code

Can any one help me to input the speed, accuracy and count to a database. I can't able to take the value because its JavaScript....

Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once.

Does anyone know how to do this please?

Thanks so much for your help.

I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free.

I have Googled, but there are so many that I am almost dizzy with the choices.

Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic.

Does anyone know how to make URL links that use Javascript still work when
users have Javascript disabled on their browser?

The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version.

I tried the <script><noscript> tags, but I'm not sure if I'm using it
correctly, as my URL completely disappears.

Below is my HTML/Javascript code:

<p class="download">
<script type="text/javascript">document.write("<span
style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\"
onclick=\"window.open(
'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+
Math.floor( Math.random()*11 ) );\" >The Child Magazines Media
Kit</a></span> (PDF 1 MB) ");</script>
<noscript><span style="text-decoration: underline;"><a
href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf"
>The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript>
</p>


Thanks for any help,
Michael
