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']?
Rather than just creating a two dimensional array and keeping up with which occurrence number represents, is their a way to identify fields within a one D array? For example:
Code:
MyArray[i][3] = DiffY/DiffX; //Current way
// Preferred (if possible):

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.

Ok i want to name an alert so that It can be called upon without being in a function. Code is as follows:
<html>
<head>
<title>
Sign In page
</title>
<script type="text/javascript">
function AccessText()
{
return document.getElementById("FirstName")
}
</script>
<script type="text/javascript">
{
window.alert("Welcome, "+document.getElementById("FirstName")+" you are signed in")
}
</script>
</head>
<body>
<form>
<input type="text" id="FirstName" value="Enter your first name">
<input type="button" value="Sign In" onclick="">
</form>
</body>
</html>
OK so how would I assign the window.alert a name?? So that I can access it with the onclick feature? Thank you.
I wrote a generic script to handle getting a cookie value, setting a cookie value, and replicating the $_GET request. I'm wondering what I should call a script that covers both cookies and URL requests.
View 2 Replies View RelatedI was peaking around on the W3C site to see if I could find a clear definition of which characters are allowed within an ID.The problem is that I have a series of divs that have id="aq-1234" "cd-456" etc. I have no real control over the - in the name. What would be another way of clearly identifying an object without the id? <td id="aq-1234"> is what I have now. I've not used the rel="xxx" that I see some people use. Would that be acceptable? Clearly $("#aq-1234") is not.
View 3 Replies View RelatedI've got an input with a value. The input is called 'command2' and I want to send it's value to the 'rover2' object (although I don't know if that object exists yet). I test and say if(rover2){... and if not then I create the object/if so then I insert the value.Question is: I want to do:Code JavaScript:var rover2 = new Rover();but I want to pass the name of the new object by association, so in effect:Code JavaScript:var "rover"+i = new Rover();How would you do that? So that the objects and their names are generated dynamically (or [perhaps a better explanation] so that the string value of a variable can be used as the name of new variable/object)?PS Bonus marks: If I hold HTML fragments as an object and those fragments include inputs, is the value of the input collected as well? i.e. if I have
Code HTML4Strict:
<fieldset>
<input id="foo" type="text" />

what's the syntax for naming a variable on the fly? for example a for loop sitting inside a function:
for (var i = 0, j = divs.length; i < j; i++) {
"item"+i=whatever;
}
where "item"+i evaluates to item1, item2 etc...
I'd like the variables to be available outside of the for loop as well ....
I'm building a website that needs to be able to check the value of an
element and give it a new value based on what it's current value is.
So for example, if I had a product and my code read like this...
<input type="text" name="name" size="20"><br>
<input type="text" name="description" size="20"><br>
<select size="1" name="public">
<option value="1">on</option>
<option value="0">off</option>
</select>
Assuming the name of my form was "form", I could access the value of the
text fields by "window.document.form.FIELDNAME.value" and the select by
"window.document.form.public.selectedIndex". But the page i'm working with
has multiple products listed and so I've addopted a nming convention for the
elements name's so that I could access it more efficiently in PHP. So for
example, I'd have multiple products as such Code:
I have the following code which adds a dynamically created textbox to a form:
function addarow() {
if (count > 5) {return false}
count ++;

I have 2 select windows and have a function to move items from one select window to another. That was working fine until I had to change the names of each box in order to be able to post the select window as an array in PHP.

<select size="10" name="select_list2[]" id="select_list2[]" MULTIPLE>

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 ...

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:
Code:
I'm trying to insert each of the elements of the katMusik-array into the checked-line, thus checking the checkboxes with those names. However, it doesn't seem to work.
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:

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.
