Log The Content Of The Global Namespace?

Jun 12, 2011

Using the Firebug console is there a way to log the content of the global namespace? I particularly want to recognise when something is added to it by my code. I could step through my whole code :( but I'm hoping there is an easier way.

JavaScript Namespace – IE7 Says Not Implemented

Oct 29, 2007

I am having an issue with adding namespaces to my JavaScript. When I run this code in FireFox everything works fine. When I run this code in IE7, I get and error saying “Not Implemented�. It is pointing to the line of code where I Instaniate the object (testNameSpace.menu = new js.JavaScriptCodeIsHere(); ). Does anyone know why this works in FireFox but IE7 tells me I have not implemented something? Code:

JQuery :: Creating Elements And Setting Attributes With Namespace

Mar 7, 2011

I'm working on an app, which createsvisualizations based on SVG. I was using jQuery SVG by Keith Wood at first [URL], but at some point I've noticed that it's very inconvenient for some stuff and wrote my own functions to handle everything. One of the quirks when creating svg trees dynamically is that you have to create all elements and set attributes using the SVG namespace ("[URL]"), otherwise they aren't rendered correctly by browsers.

Here's an example of how you create a text element...
var svgns = "[URL]";
var newText = document.createElementNS(svgns,'text');
newText.setAttributeNS(null,"x","0");
newText.setAttributeNS(null,"y","0");
$(newText).text("some text");
$(svgGroup).append(newText);

There doesn't seem to be a way to do that more effectively using jQuery. For instance, you can't use attr to set multiple attributes, since it won't use setAttributeNS.

JQuery :: Selector Works With Custom Tag In Namespace <dl:object>, Including In IE?

Jan 26, 2011

Actually the selector works in this form:

$objects = $("dl\:object",contextelement)

but not in this form: $(element).children("dl\:object").I don't care that it doesn't work in the second, because I only need one time access, since I replace these custom elements with valid html using javascript, as soon as the page loads (sort of like xfbml I guess).My concern is that it DOES work even in IE, which only returns a tagName of "object" from <dl:object>. (given the following html attribute: <html xmlns:dl>). So I'm suspicious. I've tried following the code that matches the selector, but I can't do it, it's too complex for me to follow in a reasonable time.

Event Groups - Attaching Event Listeners With A Namespace

Dec 16, 2010

The DOM Level 3 specification has a section (1.2.2.2) that talks briefly about "groups" of event listeners. What does this mean? Is this similar to attaching event listeners with a namespace, as in jQuery: "event.my_namespace"?

Using A Function To Create A "namespace"

Mar 26, 2007

I have seen namespaces created (or really to avoid creating namespaces) like this

(function () {
alert("hi");
})();

but today I saw this

new function() {
alert("hi");
};


Is there a difference? The second one looks much cleaner so I'd prefer to use that one.

Syntax

Jul 20, 2005

I am trying to order a laptop from the Dell online shop but
everytime I try to press 'continue' after picking the options, I get
an error message in the lower left hand corner of the browser.
I'm using WIN 98SE with java enabled on my laptop.

The error log says:
Line: 1
Char: 1
error: object expected
code: 0

And this is the line which pops up when I place the cursor on the
'continue' button causing the above error:

javascript:next_page(&#391;','c=us&cs=19&kc=6V602&l=en&oc=5100FS&s=dhs');

I would assume there's a bug in that line. Although there's little I
can do about it other than forward it to the Dell folks - my pgming
background has me curious as to what's causing this!

Is This Syntax Correct?

Jul 23, 2005

onClick="javascript:myFunction()"

or does it HAVE to be

onClick:"myFunction()"

I know 'javascript' is not necessary here, but just want to know whether to include it (which sometimes I do by mistake) is incorrect syntax or not..

Syntax Error

Aug 12, 2005

I have this JavaScript that is supposed to show random products from my
database, and show something different every time you refresh or revisit.
But I keep getting an error - on my computer - that says Syntax Error in
Line 2.

There is no error on most other computers, and the products show, but
another script on the page, an article title scroller, stops - on most
computers, but not all. It says "no articles available".

I've tried the script on an asp page and a htm page, all by itself, but it
still doesn't work. I tried changing all kinds of settings in my browsers,
but nothing helps. I'm on XP, SP2, which I've heard has some problems
handling javascripts. I don't know if that's true, but if it is, I know that
lots of other people will have the same problem as me when they view the
page. Actually, I think it is a good thing, that my computer is pointing out
this error. I get the error message in IE6, but in NS8 and FF, I just don't
see the products. No error message.

Anyway, here are the first three lines of the script:

<%
if TRIM(request.servervariables("http_referer")) = "" then
%>

Using spellcheck, I found that referer is spelled wrong, it should be
referrer. I don't know if that is right for javascript (or asp?), but
correcting it didn't make a difference.

The script is JavaScript on an asp page, and it is called in an htm page.

Is the error obvious from the 3 lines?

Syntax -0 At End Of Replace()

Nov 13, 2006

I found this in one of my old scripts but I can't remember what the -0 was used for. I remember it was a shortcut method but I can't remember for what. Does this ring a bell with anyone?

var Pattern = /px/;
var T = paddingArry[0].replace(Pattern, "")-0;

ECMAScript Syntax

Jul 20, 2005

Does the "semicolon insertion" really affect you if you format code as

function x (y)
{
// ...
}

instead of:

function x (y) {
// ...
}

The jslint page complains about lines ending in ) due to the nebulous
idea of "semicolon insertion". I have not reviewed the ECMAScript pdf
in great detail to try to pin this pretty-printing issue down. In
general, I find that code formatted in the "K&R" style (opening brace
on same line as if, while, function) confusing and difficult to read
compared with placing curly braces on separate lines.

On another subject, the difference between inner functions defined
explicitly versus defined using function expressions seems like a good
one for a FAQ. Under what circumstances does it make a real
difference whether you use function expression versus function
statement versus Function object?

Using Var Syntax Problem

Jul 20, 2005

Here is the code:

function fnSelectOption(fieldname)
{
document.mainform. + fieldname + .value = "value";
}

It obvliously bombs where I am trying to ref the param "fieldname". I
realize it is a simple syntax issue but I cannot seem to figure it out.

JQuery :: Syntax For$() For A Different Doc?

Oct 27, 2010

I have a text string that is a complete html doc. How do I tell jquery to parse that?

Variable theDoc holds the other html doc.

I tried:

var doc = $(theDoc);

If it is "this" doc it looks like: var x = $('table:contains('test')).html(); I tried: var x = doc.find('table:contains('resume')).html();

It keeps saying something is null.

So what is the syntax to look inside another doc , not the one the code is currently in?

PHP Variables To Javascript Variables

May 6, 2006

I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.

I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.

I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:

var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>

but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:

Substring Syntax In Javascript

Jul 23, 2005

Trying to debug someone else's javascript code. There is a line that

looks like this:

req = req.substring(req.length-2, req.length);

From what I can gather in their comments, they want to capture the last two characters of the string "req".

I'm guessing that the above line won't do that, and they want to change it to

req = req.substring(req.length-1, 2);

In other words, the parameters are starting position, and length. Is that correct?
