I've been experimenting with Local Storage. I can do things like this just fine:
But if I do this:
...then place it in local storage, reading it back gives me a TEXT STRING that says "[Object object]" and not the actual object.
I would like to be able to store multiple values in one object, but it doesn't seem to work.
I also tried to store a variable obtained with "document.getElementById" and when read back it just says [HTMLDivElement] (something like that) instead of the actual element.
Am I doing something wrong, or does local storage not support objects? (btw, tested on FF 3.6).

View 1 Replies View RelatedWhat I am trying to do is to create an array that could hold "dates". (1/3/2004)
I have a file that has 6 sets of 3 dates. So 18 individual dates.
The program reads the file and takes in the dates.
What I have is a while loop. Inside the while loop it reads each set one at a time and passes it to a method which will sort the dates in the chronological order. Code:

First off, The application in question can be found at:[URL]... It uses pixastic, then the "convert to png" button converts the canvas to a saveable image. The application is going to produce a slideshow using the edited images. I obviously have the option of allowing my users to save the edited images locally, and then reload them to create the slideshow.
Ideally though, I would like this image loading process to be done from within the browser though.

View 2 Replies View RelatedA <select> box is dynamically created based on a table in the database. Using jQuery, the user can then select multiple email addresses (the value of the options in the select box), and remove them from the select box completely. This leaves only the email addresses the user wants to include in the email.
The problem I've encountered is that the once the user is done removing options they don't wish to include, they have to then select all the remaining options before hitting submit in order for the mail processor to see them as addresses to include.I was thinking maybe instead of the submit button, I just create another button tied to a jQuery function that selects all the remaining values, and then submits the form for the user?
Does any one knows the javascript that read step by step single line from form and then store in array and that array use 4 further references.

i need to ask the user for details about a car, i will not know how many cars are going to be stored and therefore need an array i think. I need the function for asking the user and will need to repeat the code later in a menu. at this stage i just want to ask the user for input, store it in array and use an alert to check if it works?

I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.

//This is an example of a problem im having in my own code...
//I want to access the name of the object within the links array wintin the object...

I am following an example of an array in
http://www.faqs.org/docs/htmltut/im...famsupp_59.html. Here
is a part of the code:
var rollOverArr=new Array();
function rollover(pageImageName)
{
if (! document.images) return;
if (! rollOverArr[pageImageName]) return;
if (! rollOverArr[pageImageName].outImg)
{
My questions are:
1 what does (! document.images) means?
2 where does .outImg come from?
Is it possible to have an Object as the key for an Associative array
like in the following example....
function Obj(var1, var2)
{
this.var1 = var1;
this.var1 = var1;
}
function test() {
var sectionArray = new Array();
var obj = new Obj("c","k");
var obj2 = new Obj("3","n");
var obj3 = new Obj("v","qk");
sectionArray[obj] = "king";
sectionArray[obj2] = "queen";
sectionArray[obj3] = "joker";
alert(sectionArray[obj]);
}
This does not give any error but the alert says "joker" instead of
"king". Is there anything wrong with my code or is an Object something
that just can not be used as a key.
If it is the latter can someone please suggest another way for me to do
it? Can I use a concatenated String instead of an object? My only
problem then is how would I extract the values from the String, does
JavaScript have a tokenizer method like Java?
Is it possible to have an Array object (or an object derived from
Array) that is 'aware' of other code modifying its contents? I'd like
to have such an "onModify" function process an array everytime the []
operator is used to make a change. I know you can derive from Array,
but you cannot directly override the [] operator. Any way to make
this possible?
// possible definition of 'SpecialArray'
...
function OnModify()
{
// process the list
}
...
//an example of use ...

View 3 Replies View RelatedHow do I explain this? I am grabbing several elements from my document and placing them in an array, using jQuery. When I test the

I have a array to store some student information, eg:
var s = new Array('2006001', 'Apple Joker', '5B');
normally, We get the data using s[0], s[1],s[2] ...
How can I define them more readable like

I have a function were the input parameter can either be an
string,array,dom node or NodeList (getElementsByTagName()) and I have
somthing like this function which works great for what I want in every
case except if the pNd is the NodeList at which point I end up with the
nodeList in the first element of the array instead of acting like the
array would.
function doSomething(pNd){
if(pNd.constructor != Array){pNd = new Array(pNd)}
return pNd
}
So my question is how is there any easy way to figure out if pNd is a
NodeList ? When I use pNd.constructor on NodeList all I get is [object]
