I've noticed that if you declare a variable in one function, then call another function, the variables cannot be accessed in that function. Is there any way to get the value of a variable declared in a different function?

I'm new here, and new to js. Here is my problem: I have written out a code to make an image switch from state 0 to 1 and back to 0 again (an eye blink). The code works fine, but I would like to write the functions with arguments so it could be applied to more images. I have tried for a few hours (and searched forums) and am getting no where. Here's my code.
Code:
function home_blinkDown()
{
//alert('blink down');
var t = setTimeout("home_blinkSwap('home_js', 'images/main/home_blink.png')", 2000);

result = $("apot", xml).text();
//<-- this variable is not global... why ??
message = $("message", xml).text();
//<-- this variable is not global... why ??
alert(message); //<--here variables are shown ok

I'm trying to trap a user entry that cannot be found in the database. When a code is entered, the page should give a "Code Not Found" message if it is an undefined value.

I would like to display the number 1 at first and then 2. but this code produces number 2 for both alerts. I was able to achieve what i wanted with "new" constructor when creating functions but this is not a good practice and after all i am passing these functions as an event handlers and it can't be done with "new" keyword because it is throwing error. I think there are some solutions with arrays e.g the x would be an array of numbers, but i don't like it. Am i missing something important?

I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so:
<script type="text/javascript" src="gameSetting.js" ></script>
<script type="text/javascript" src="gameLibrary.js" ></script>
In gameSetting.js I have:
$(document).ready(function()
{
// call some functions / classes in gameLibrary.js
}
in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load.
However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem.
My options are:
1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense.
2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers).
jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work.
I was trying to "pin" a menubar to the top of a site. It should allways stay on its absolute position. Especially when the user scrolls the page...
I did like this:
<div id="object1" style="position:absolute; visibility:left:50px;
top:50px"> MENU </div>
called from a timer:
document.object1.style.top=50;
OR
window.document.object1.style.top=50;
OR
document.object1.top=50;
OR
window.document.object1.top=50;
none of them worked...now what?
I'm trying to access the source of an HTML page with as few alterations
from the actual source (as in, that seen from the View Source option)
as I can. The method document.documentElement.innerHTML returns the
HTML source, but adds HEAD and other elements if they are absent from
the source, and takes out whitespace (i.e., line feeds, carriage
returns and tabs) within tags and between tags. The follow function:
function xhr() {
xhr = new XMLHttpRequest()
xhr.open("GET","test-page.html",true);
xhr.onreadystatechange = function() {
if (xhr.readyState==4) {
alert(xhr.responseText);
}
}
xhr.send(null)
}
doesn't add or alter any tags that are absent in the source, and does
not take out line feeds within tags; it does, however, still take out
all non-line-feed whitespace within tags and all whitespace in general
between tags.
It seems that preserving whitespace is all that I need, but I haven't
found a way to do that through my searches. So is there any way to get
the unaltered HTML source of a page without innerHTML or applets, like
a better version of the XMLHttpRequest object's responseText method?
I am using a pre-built javascript DatePicker. It uses window.open to display
the Calendar and works fine if the user clicks on a link for a specific
date. The proper textbox in the parent window form is populated and the
DatePicker closes.
The problem is when a user clicks on the parent window, the datepicker is
hidden behind the parent window. Beleieve it or not, this creates a real
problem for many users.
Is there any way to put up an alert to the user and then set focus back to
the datepicker if the user clicks on the parent window by mistake?
In the datepicker.js there is a reference to the window created:
ggwindow = window.open(..parameters)
So I tried something like ggwindow.onblur=dont_close_me() referring to a
function that displays an Alert and then sets focus back to the datepicker
window. I know that onblur is an event and not a property or method of the
Window object, but I have also seen mentioned that the onblur event can be
applied to the Window object.
During window creation I don't see a way to set the onblur event for the
created window.
I need to keep a log in a test application, so I'm using a textarea for that, and I'm appending text using the+= operator.Follows the trace function which fills the textarea:

Ok first the bad, it will not work from a stylesheet, you have to use style="display:none" all over the place, I will try to fix that without adding more than 2 lines to the script somehow, I hope. you can not have line breaks in the innerHtml statements in your links(I think that's normal anyway). javascript:void(0); will not work for an iframe, you have to use #(or #null to keep from clicking up to the top of the page) for the hrefs, I don't know if that is a bad thing or not, there has to be something better than both of those options. now the good, if you do not have access to the head of a page, everything works from the body of a page. it is good for making ul/ol tags for a vertical menu without that complicated scripting having to differentiate ul/ol text and li links in those scripts for just a simple menu, the ecmascriptmenu is the only one that makes sense to me, hope he gets his server fixed. the script seems to work with or without a doctype in IE6 firefox and safari. people always wonder why I try to make these type of scripts, I usually maintain long lists of links so I like to provide small previews(iframes that do not load until clicked) for each link, the best part is that IE firefox and safari react to it flawlessly unlike most other types of scripting, one script had an eval statement that gave me tons of trouble taking it out and the other script I took out a server sql proprietary call to a rowid for a table and made almost any html element be a target(a p tag for instance).

i have developed an application that allows users to post code on their profile on various social networks, and activate the application by submitting data via an html form from within their profile. the application works fine.the form action is processed on my server the problem is that after they submit the form, the users are directed to my website and the display of the results are presented on my website - at hxxp/xxxxxxxx.com/process.php.
i am trying to keep the users on their profile on their social network. i tried unsuccessfully using targret="_self" and target="_blank" as part of the code they are posting on their profile I am trying to figure out a way that they will not be directed back to my website.
here is the way the code posted on the users profile on their social network looks like:
<form action="hxxp://xxxxxxxx.com/process.php" method="post" name="process" target="_self">
<textarea name="somename" id="somename" rows="5" cols="5">blah blah
I have a menu with a horizontal submenu. What I want is for the submenu to stay active if the mainmenu link is activated... This I got so far. Now what I cant figure out is how to make the active submenu hide when hovering over the other mainmenu links... And show again when not hovering...
Here is what I have tryid so far:
Code CSS:
#navbar {
top: 0;
left: 0;
[code]...
Now this allmost does the part except hidding the active submenu when hovering...
What I would like to achieve is that when a user goes back to the first page that his/her selection of the cities is still available. All items that have been selected are in the right hand box. This list is again empty when they return to this page via the "history.go(-1)" link.
The page is in dev status and in german, but it is very easy to understand, so it shouldn't be any problem for you guys. The javascript code can be seen in the source code on the first page. The left list is filled with a mySQL statement in the first place.
Of course I can to some PHP workaround by evaluating the submitted variables, but this would be much more work. I want to know if there is an easier approach? Code:
Is it possible to keep values in the status bar an then get them?

I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper()
