What is the difference between Object Literals and Array Literals in JavaScript? I know it has something to do with the length method but i don't fully understand it.
So I'm searching for a good crash course on localstorage and interacting with it in Javascript. I want to build a to-do list webapp with some extra functionality but it would be just for 1 user. I don't want to mess with php/mysql and have the server doing anything. Links to tutorials would be best :-D

I've been having a crack at some of the problems over at http://projecteuler.net/ with JavaScript. I've been using a simple html page and running my code in script tags so I can log my results in the browsers' console. When experimenting with loops I sometimes cause the browser to crash.
Is there a better environment for me to do this kind of development?
I was implementing a routing algorithm in javascript, but when I assign a negative one variable in the array gives me this error: invalid array length.
var node = new Array()
node[0] = new Array(6,7)
node[1] = new Array(5,-4,8)
node[2] = new Array(-2) //Here, invalid array length
I do not know how to resolve this error.
Applet Communication:

2. show dynamic mouse position in applet-window and display position in html-site. use live-connect between applet and browser communication.
I have a table row with 4 columns on my ecommerce site and I want to replace the content of 1st column if total amount in last column (TD class "total") is over 10 EUR.
How can I do this with javascript only, I guess somehow to enumerate through the table rows and look for a correct row (one with the last column class as total) and then access the content of 1st column on this row but how?
Is there a way to add a method to all javascript functions without using the prototype library?
something along the lines of :
Function.prototype.methodName = function(){
return dowhateverto(this)
};
this is what i tried so far but it didnt work. Perhaps it is a bad idea also if so could you please tell me why?
if so can I add it to a set of functions i choose
something like :
MyFunctions.prototype.methodName = function(){
return dowhateverto(this)
};
where MyFunctions is an array of function names
thank you

What I need is to have divs with id's (1,2,3...) and be able to insert a div between, for example, 2 and 3, with jquery, and then have that be the new three, and three becomes four, four becomes five, etc. I've got the div insertion working, I just need to know how to reorder the divs. Any ideas?

I have a print function on a page in my website. the problem is, when it hits this line:
<script type="text/javascript" src="http://cdn.powerreviews.com/repos/12564/pr/pwr/engine/js/full.js"></script>, it tries to load it, and just never finishes.
Any ideas on how to get around that?
Hello,
I'm running into a scenario where at random times I am getting "Access Denied" when executing javascript. It is not repeatable and occurs in random places of my application. There is not indication of what is causing it in the logs and I'm really at a loss on this. It seems to be UI problem only. However, there is no reason it should appear as I do not have any such permission checking to could be getting triggered.
Thanks in advance
just wondering if anyone knows anything of using javascript to set html to new content instead of linking to new pages, if this is generally a bad idea or if it kind of hurts SEO(which im kind of new to)
Basically the home page displays given content, and the links to like contact pages and stuff, just change the body content to what would normally be a separate html page. my OCD kinda bugs me when pages reload and either flash the background or its offset somehow, so i wanted to know if making sites like this was a bad idea or whatever-
i suppose at the least, i could create duplicates/hidden pages for SEO purposes

I Have a PerformancePoint Server 2007 Dashboard in a Sharepoint 2007 page.
In my Sharepoint page, there's 2 Filters who get passed to the Report, and I need to print this report in the page (in another button, not the SSRS one).

Since I'm building a dynamic site, I need to track the changes between pages, ie. Ajax calls, POST, GET stuff and similar stuff.
I'm looking for the same functionality like in Firebug (where you can enable "persistent" and the console is not cleared every time you reload a page or submit a form.
So, my questions is: is there a way to make Google Chrome JavaScript console persistent?
(And if yes, how?)
