Sharing Global Variables Accross Pages

May 23, 2004

I have an HTML page which loads another page inside an IFrame. Each of the two pages has its own javascript code.

I would like to be able to define one global variable which will be accessed from functions in both scripts. The variable must be single. That means that if a script in one of the pages changes it, the change will be seen by the scripts in the other page.

Global Variables

Dec 12, 2005

I have some code that does this:

function openWindow(windowName){
timeStamp = new Date();
var timeStamp = timeStamp.getTime();
document.getElementById(window).style.display = 'block'
}

blahblahblah . . .
openWindow('order'); // calls openWindow function and sets timeStamp variable.
alert(timeStamp);

then I get error: timeStamp is undefined. Why? I defined it as a global variable within openWindow. Am I just doing this wrong?

URL`s As Global Variables

Feb 12, 2006

I`m building a site with html and GIF files on one server and audio files on another. That means I have to use absolute references to the audio files.

Problem is, the site will probably dwell some day in other server(s), and may also use a different audio format. I like to be able to globally change url strings and suffixes of the referenced files.

I think I can`t use "base href" because relative references (to files that are on the local server) would be affected.

The code looks something like this:

<a onclick=document.all.music.filename="URL/FILENAME.ZZZ" ...

I like to set "URL" and "ZZZ" on a separate file.

Where Can I Declare Global Variables

Jul 23, 2005

I prefer to keep all my scripts in an external '.js' file. I am currently loading the external '.js' file from the header. Problem is I would like to declare a global variable in the external file, but I keep getting an error about the object does not exist.

Can someone tell me where or how to declare a global variable in an external file that is available after the page is loaded.

AJAX Without Global Variables?

Aug 16, 2005

Is there a way to "pass" an XMLHttpRequest object to the callback
function for onreadystatechange? Or a way to access it from
onreadystatechange? I would like to avoid the use of a global
variable...

Example:

/* How do I get rid of this global variable? */
xmlHttp = new XMLHttpRequest();

function myFunc()
{
...
xmlHttp.onreadystatechange = myCallBack;
...
}

function myCallBack()
{
if (xmlHttp.readyState != 4)
{
return;
}

...
}

Any ideas?

Existence Of Several Global Variables

Jul 20, 2005

Suppose I have global variables: x1, x2, x3
and I have a function that needs to assign a value to a new global variable
x4

something like
function foo ()
{
count = 0;
do {
count ++
varname = 'x'+ count
} while (globalExists (varname)

eval ( varname + ' = "I am new in the x-series" ' )
}

how would the function globalExists () be implemented ?

Global Variables Not Working, But *seem* Right?

Dec 29, 2009

Here's my code:

//document.write("Test");
//Declare arrays
stats = new Array(6);
statMods = new Array(6);
/*
//Populate stat and statMod arrays

[Code]...

without first calling the other function that actually assigns values, it still works. As I said, though, if I assign values outside that function, then it all falls apart.

Global Variables - How To Interact With User

May 15, 2009

I'm new to javascript, but I need help and really hoping for a reply. I was trying to find an answer in Google but no result. So I have two table containing images, at the beginning only first table is displayed. Then when one of the images in the first table is clicked, a second table should appear, and user should click one of the images on that table. And that image should replace the one that was clicked originally in the first table.

So the question is, when the user clicks an image in the second table, how do I know what was originally clicked in the first one? I tried to use global variable but that doesn't work.

Using Global Variables Defined In HTML Page?

Oct 14, 2011

I have an external js file used by an html page but I want to use global variables defined in the html page in the js file. for example...

<html>
<head>
<SCRIPT type="text/javascript"
var test = "1";
</SCRIPT>
<SCRIPT type="text/javascript" src="jscript.js">
</SCRIPT>
</head>

So I have var test which is defined in my .html but my jscript.js also uses the variable. I am doing it this way because I have a lot of pages that are simular using the jscript.js functions but each page has different quantities and values of variables used.

Accessing Global Variables - Function DisplayResults - ImageArray

May 5, 2009

I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;

However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?

Here is the code for displayResults(imageArray); :

Passing Variables Between Web Pages

Jan 19, 2004

I am attempting to display info put into an array from an onClick() event in a different page - I have created different functions which populate an array with different info dependant on which link the visitor clicks ie HTML Code:

<a href="nextpage.htm" onClick="functiontopopulatearray()"> SELECT</a>

The function seems to work fine, however when the next page loads and I attempt to access the array elements they are now undefined - both pages are linked to the same JS document.

Testing Data Types Accross Multiple Function Parameters?

Aug 20, 2010

So I have a function, and in that function there are two paramaters: index and newLocation. Each of these parameters can initially either be an integer or a string: The string can only be the values of "first" or "last". I can do a long set of code for both parameters, but I was wondering if there was a way to iterate through the parameters to make the code more compact and reusable.

if(parseInt(index, 10) == "NaN")
{
if(index == "first")
{
//The first index of the array
index = 0;

JQuery :: Retrieve Content From DIV Sharing CSS Class

May 21, 2009

I have a bunch of <div>'s on a page, each of which shares a CSS class titled "portlet-header". What I would like to do is retrieve the content inside each of these div's, and then construct a string of each div content separated by a comma. At the moment I can retrieve the total content from ALL of the div's sharing the "portlet-header" class by using:
$(".portlet-header").text()

However, I was hoping that there would be a way of looping through each div of the shared CSS class in turn, constructing a string of the following format:
div content 1
,div content 2
,div content 3
etc...
I had a look at the .each method but couldn't get anything working.
