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?
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.
<script>
//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...
[code]....
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 ...
How do I convert the this object to an array.

How do I explain this? I am grabbing several elements from my document and placing them in an array, using jQuery. When I test the
Code:
typeof
this item, it returns as an Object, not an Array, which is problematic for IE. Firefox seems not to have an issue with
Code:
Object.length
, but IE won't have any of that, so I need
Code:
Array.length
or do I? In the end, I just want IE to know how many keys are in the Array/Object...
What I'm trying to do, I think, is to use elements of an array as a part of an object. Here's a lil' code snippet:

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
s['studentID'], s['studentName'], s['class']?
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]
i'm an actionscript3 developer who is somewhat new to js/jquery and am struggling through creating a site using jquery.I would like to be able to use the show/hide/toggle methods to switch between content using a standard navigation list. basically, what I want to do is this:1. store list of 10 <divs> in array with the id set to w1_blog, w2_blog, etc2. list of 10 links with ids = w1_blog_a, w2_blog_a, etc.3. store references to divs and links in array/s4. add event listener to each link5. .click event calls function that loops through each blog entry and shows the one matching the link (w1, w2, etc) and hides all others.I could do this in 2 mins in as3 but I'm struggling with the js syntax, despite it being very close to as3. It should (I think) look something like this:
$(document).ready(function(){
var blogArr = new Array();
var blogLinkArr = new Array();

I got an php page who picks up data out of my data base and puts it ina multidimensinal array. That array is being encoded to Json$event = json_encode($super_array);Then i made an javasript get funtion to get that array to my mainpage.
function get(){
$.get("../position of my file/test.php", function(data){
alert (""+data);
[code]....
What I'm trying to do here is even possible.
I've tried numerous variations of the alert line with evals, brackets and jQuery syntax but always seem to get the error:
XML filter is applied to non-XML value ({one:["1", "2", "3"], two:["a", "b", "c"]})
Which makes me think I'm either attempting something stupid or only missing my target slightly.
The code will be running within a jQuery project up if that helps in any way.
I have an array but I'm not exactly sure how to finish the build using an if statement. I have 6 elements and need the build to load a different top image for each array that loads that matches the specific element. Here is what I have but it only shows the first top image no matter what:
<LINK REL=StyleSheet HREF="scrolling_popup/scrolling_popup.css" TYPE="text/css">
<script type="text/javascript" language="javascript" src="scrolling_popup/scrolling_popup.js"></script>
<script type="text/javascript" >
var array = new Array();
array[0]='<a href="[URL]" target="_blank"><img src="[URL]" border="0" alt=""></a>';
array[1]='<a href="[URL]" target="_blank"><img src="[URL]" border="0" alt=""></a>'; .....
I have an array of objects that I would like to sort through and "join" objects that are the same. And if they are the same, I need to sum up the number value given for those two items. So I guess Im sorting through and maybe even recreating this array to get rid of duplicates while I tally quantities. see the screenshot of my array of objects to help understand better. The highlighted 'sPSPN' would indicate that it is a duplicate item and its 'fUnits' need to be totalled. in the end I would have a total of 3 objects, because 'sPSPN'= BT-221-44 would now be only one object with 'fUnits' = 35.

I'm trying to send my array object through ajax using the jQuery .get method, but when it sends, ids show up as multiple parameters and I'm not sure if that's the way to do it.
Here is my code:

I'm a little puzzled over the possibility of accessing an array. I've declared the previd id - in the proxy.invoke call which works just fine (we have already implemented an .each loop which also works. My problem is this - after accessing the proxy.invoke function, the previd is populated correctly with push but after the call, we cannot seem to access the previd array to make a join to a string. Here's the basics of the code.
var previd = [];
proxy.invoke("validdateIDCard", p_caregiverid,
function(validaterID) {
var valcard = validateID;
previd.push(valcard);
}, onPageError);
var finalvalue = previd.join("|"); <-- this is where the problem lies - cannot seem to read the variable...

I have created a class array (or variable that contains an array) and am trying to add an element to the array when a new Element object is created. Thus, the line of code to add a new element to the array is within the Element object's constructor function. However, the browser just gives me an error "object expected on line 9", the line of code trying to add an element to the array.
Are arrays not functional within objects? Or, is it that the array is made as a class variable?
Code:
function Element() {
// INSTANCE VARIABLES
this.name = "newElement" + Element.total_elements_created; // GIVE UNIQUE NAME
// INITIALIZATIONS
Element.element_count ++; // INCREASE TOTAL NUMBER OF ELEMENTS EXISTING
