Mozilla And Global Scope
Jan 22, 2005I've just realized that in Mozilla pointer variables always have local scope in a function. Unlike IE. I wondered if Mozilla was able to do it in some other way? readXML() is an init() function which might be a constraint - I'm no javascript expert.
// The following won't work in Mozilla.
var record;
function readXML()
{
record=xmlDoc.getElementsByTagName("record");
}
alert(record[0].childNodes[1].firstChild.nodeValue);
Sliding Panel - Take The Object OSidebar Out Of The Global Scope
Jun 10, 2011I created this code for a sliding panel and it works well. But I'm struggling to take the object oSidebar out of the global scope. I would prefer that it were a property of the clicked event object. That is, I want to be able to use 'this.oSidebar' within the click event. I've posted the whole page here along with the click image.

Function Defined In Global Scope Not Being Called By SetTimeout
Feb 2, 2011I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.Why is an object reference assigned to what was previously a string?
View 6 Replies View RelatedOverwriting A Prototype Function And Keeping Scope?
Nov 3, 2010Not sure if this is possible, but I have an external script that creates an object, and I want to overwrite some of its functionality, but keep the scope.
Here is a basic example:
Code:
<script>
Obj = function (userConfig) {
this._init(userConfig);
[Code]....
I want it to log two Objects, but instead I get two window elements. Is this because I am declaring the functions in the global scope, and not from within the object?
Anyway I can keep the scope of the object, whilst still overwriting the function?

JQuery :: GetJSON Method - Scope Of Variables
Sep 16, 2011I'm using jQuery's getJSON method to get the current date from a foreign server. I however, should this request fail (e.g. if the server is down), I want to have my page fall back to a sensible default.
What I'd like to do is this:
var date = "sensible default"
$.getJSON(url, function(data){ date = new Date(data.datetime); });
if request was successful date will contain new Date(data.datetime);
if request was unsuccessful date still contains "sensible_default"
What I have is this:
var timezone = "Europe/Berlin";
var date = "sensible_default";
$.getJSON("[URL]"+timezone+"&callback=?",
function(data){ date = new Date(data.datetime); });
alert(date);
But this produces an alert of "sensible_default", despite the fact that the getJSON request fired correctly.
Variables Scope In Dynamic Functions - Display The Number 1 At First And Then 2
Mar 19, 2011I have got this piece of code:
Code:
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?
Global Variables
Dec 12, 2005I 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, 2006I`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, 2005I 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, 2005Is 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, 2005Suppose 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?

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, 2009I'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.

Sharing Global Variables Accross Pages
May 23, 2004I 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.
Using Global Variables Defined In HTML Page?
Oct 14, 2011I 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.
