I have to stuff multiple objects in global var populated in a foreach loop and seperated by a comma.The loop is:

// GlobalG.objects;
$('.class').each(function() {
var title = $(this).text();
var src = $(this).attr('src');

JQuery :: Creating Objects Within Each()

Oct 7, 2010

I have a tab compopenet object that works by passing a dom element to a constructor... which then finds all the relative elements to that element using .find() and adds the necessary behaviour. Now, since I have multiple tab components on the same page, I'm using each() to iterate through the dom elements and pass each into the tab component constructor function.

JQuery :: Creating Objects From Within .each Question?

Oct 7, 2010

I have a tab compopenet object that works by passing a dom element to a constructor... which then finds all the relative elements to that element using .find() and adds the necessary behaviour.Now, since I have multiple tab components on the same page, I'm using each() to iterate through the dom elements and pass each into the tab component constructor function.[code]This works fine for my purposes, but after running my code through JSLint and researching here (URL...), I've been made aware that I'm pretty much throwing these objects away, since I'm not assigning them to a variable.My question really is; is this particularly bad practice under the circumstances? If I assigned the object to a variable within .each(), I'd surely be overwriting that varibale with each iteration and essentially doing the same thing?

JQuery :: Creating Objects On The Page To Load?

May 10, 2010

if I am loading content into a div using the get feature of jquery, and that content has some clickable objects in it will jquery recognize those as well? What I am doing is building a site that tracks bugs on our software. The site pulls the bugs from a mysql db and displays in a table format. There's an edit link which passes the record id number of that bug (via ajax) to a php file, where a form is filled in with the bug data and passed back, a hidden div is then shown with the form in it. Part of the code I pass back has a submit button and a close button (css styled anchors) and I'm using the same process on them as I am on the edit link but not getting any results. My script looks like this:

<script src="js/jquery.js"></script>
<script language="javascript">
$(document).ready(function(){
//hide edit form

[Code].....

how it works. Does it sneak peek the page after it loads and get all the objects into some sort of array? I'm thinking it is doing that and because I am adding other object through AJAX it is not seeing those, since the page is not being reloaded.

Is It Possible To Loop Through All Objects?

Jul 20, 2005

If you have a javascript interpreter running in an environment unknown
to you (as in what objects it exposes to the language) is it possible
to loop through all objects in some way?

This is a non-browser environment, specifically the scripting engine
for doing xslt extensions in msxml.

Creating An Array Of Objects

Oct 3, 2011

As they all have the same property set but with different values I thought I'd try creating a servo object, the create an array of servo's but I don't think I'm getting anywhere fast. Heres what I have

<!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 TransitionalEN" "http:www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http:www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
[Code]...

Once this is done and I've got all the servo objects created with their properties, I'm hoping to be able to search for all servo's with a set property i.e all servo's with servo.application = 1 would that be possible, if not I geuss I'd be wasting all our time trying to create classes I can't use the way I'd like.

Creating True Copies (of Objects) In JS (possible?)

Jul 20, 2005

Lets say I have this array:

a1 = [1,"2",new Array(2.5,3,3.5),4];

And I apply slice(0) on it, to create a copy:

a2 = a1.slice(0);

But this isn't a true copy. If I go a1[2][1] = 42, and then
alert(a2[2][1]) I will see 42 there too. I'm doubting, but I was
wondering if there is a general solution to this problem?

Dynamically Creating And Naming Objects?

Oct 13, 2010

I'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" />

[code]....

Creating And Managing Unknown Numbers Of Objects?

Jan 30, 2011

ok, so I can make an object, I can also make a new instance of that object and have it running around the screen at the same time.What I'm a bit confused about is how to go about things when I want X number of these objects.So instead of making objects seperately I need a loop. Instead of referring to each object seperately every time I want to redraw it, I want to loop through all instances of the object.Except I can't quite see how one goes about doing this.

for (i = 0;i <= 10; i++) {
var dot + i = new Dot;
}

Creating Instantatable Objects Using Pure JSON? -- No Prototyping!

Apr 23, 2007

I've been pretty infatuated with JSON for some time now since
"discovering" it a while back. (It's been there all along in
JavaScript, but it was just never "noticed" or used by most until
recently -- or maybe I should just speak for myself.)

The fact that JSON is more elegant goes without saying, yet I can't
seem to find a way to use JSON the way I *really* want to use it: to
create objects that can be instantated into multiple instances without
prototyping. I've seen (and used) JSON for singleton object instances
-- this not a problem and this is how it works right out of the gate.

But given the following custom object written the past "normal" way, I
would like to write it in JSON format, and then be able to create new
instances from the one definition. Here's an example using the "old
way" most who have been writing JavaScript for years have seen:

function Two( x, y ) {
this.x = x;
this.y = y;
}

Two.prototype.sum = function () { return this.x + this.y }
Two.prototype.max = function () { return this.x this.y ? this.x :
this.y }
Two.prototype.min = function () { return this.x this.y ? this.y :
this.x }
Two.prototype.pow = function () { return Math.pow( this.x, this.y ) }

Now, I know I can get all "fancy" with the above and do either this:

Two.prototype = {
sum : function { return this.x + this.y },
max : function () { return this.x this.y ? this.x : this.y },
min : function () { return this.x this.y ? this.y : this.x },
pow : function () { return Math.pow( this.x, this.y ) }
};

Or this:

function Two( x, y ) {
// Properties.
this.x = x;
this.y = y;

// Methods.
this.sum = function () { return this.x + this.y }
this.max = function () { return this.x this.y ? this.x : this.y }
this.min = function () { return this.x this.y ? this.y : this.x }
this.pow = function () { return Math.pow( this.x, this.y ) }
}

(The later seems to work without prototyping...!)

But neither are really as close to pure JSON as I would like, so that
I can instantate those:

var hisPair = new Two( 11, 22 );
var herPair = new Two( 33, 44 );

What I'd like is a way in PURE JSON to be able to create the Two class
(as an example) using pure JSON. I've not seen anything yet on the
web that addresses this directly aside from some pages which require
you to include another JS to allow "deep embedding" of classes using
other helper "classes" (that are created the "old way" it seems), etc.

The best I've found so far on using pure JSON to create a class that
allows *multiple* instances is something like this:

function Two( x, y ) {

var class = {
x : x,
y : y,
sum : function { return this.x + this.y }
max : function () { return this.x this.y ? this.x : this.y }
min : function () { return this.x this.y ? this.y : this.x }
pow : function () { return Math.pow( this.x, this.y ) }
};

for (var element in class) this[element] = class[element];

}

Now *THAT* works, but it's still not as "pure" I would like. But it's
acceptable for now, I guess, since I *am* creating the entire "class"
as a JSON object, and I consider the outside function "wrapper" as the
necessary "constructor." But I keep wondering... There HAS to be a
better way.

I'm just wondering if anyone knows of a place that discusses JSON used
in situations like the above. Again, I've seen an ABUNDANCE of pages
and sites that discuss JSON in Singleton usage, but nothing that
discusses it as I am wanting here.

JQuery :: Bind One Event To Multiple Objects?

setupPage();
});
$("#obj2").change( function() {

I was wondering if there is a way to simplify or clean up the code, since they are all doing the same thing and responding to the same event. This is just for refactoring reasons because my code is getting too long/messy.

JQuery :: How To List Multiple Objects / Variables

Apr 9, 2010

I was wondering how you would list multiple variables after a equal ==?
Example....
if ( pathname == schoolinformation, chaplainchatter)
$('#button_newspress_archive,#button_tech_college,#button_parent_portal,#button_transition_portal,#button_6th_form,#button_connect,#button_vacancies,#button_vle_login').css('display', 'none');
$('#school_information_sub').css('display', 'block');
if ( pathname != schoolinformation, chaplainchatter)
$('#school_information_sub').css('display', 'none');

Or even list multiple URL's within the variables?
Example
....
var schoolinformation = '/st-paul-s-website/school-information/school-news/headteachers-headlines', '/st-paul-s-website/school-information/school-news/chaplain-chatter-headlines';

JQuery :: Fire Event Once When Having Multiple Objects Selected?

<FORM><select name="category" id="#link1">
<option value=1>1</option>
<option value=2>2</option>
</select></FORM>
<FORM><select name="category" id="#link2">
<option value=1>1</option>
<option value=2>2</option>
</select></FORM>
<FORM><select name="category" id="#link3">
<option value=1>1</option>
<option value=2>2</option>
</select></FORM>
When I click on any of the select fields, I always get 3 subsequent alerts, each with the id of the clicked select field. What I would like is to have only 1 alert with the clicked select id, whenever I click it.

JQuery :: Use Multiple Array Objects As Methods For A Plugin?

Dec 7, 2011

I have a set of functions that will transition/fade photos in and out as background images. Easy. But now I would like to run the same functions on a different html page with different photos (each different page represents a different JavaScript array).

I've been reading online on how jQuery methods can be called into functions. So my thought process is to create 2 methods (1 for the original images and the 2nd method for the other images).

So here is my base code which works...
$.landingpage = function() {

/*Enable background image cycles on landing page*/
var images=new Array('/image01.jpg','/image02.jpg');
var nextimage=0;

Creating Textboxes In Loop?

Dec 22, 2009

The idea here is to have a function in javascript that would take the value from one input box (lets call it txbA) and use it as the limit for a while loop or for-next loop and create a series of input boxes each with a unique name so that its value (when entered or changed)could later be used in other calculations.

When I try something like:

function MakeMany()
{
var y=parseInt(txbA.value);
for(var x=0;x<y;x++)

[Code]....

You can call this from a button and get the text boxes, but how do I get them to have unique names such as MMtb1, MMtb2, MMtb3 etc. ??

Dynamically Creating An Array In A For Loop?

I am trying to create a function that creates an array comprised of filenames based on a given range. I.E if 2-8 is selected and a foldername of UMCP/ and a common name of college is also given, the function should return and array such as [UMCP/college2.jpg,UMCP/college3.jpg.....UMCP/college8.jpg]. Here is what I've got but the alert that should tell me the filename of the first image says it is undefined, how can i fix this?

function getArrayPhotosNames (total,count,first,last) {
/*window.alert("get Array Photo Names");*/
var folderName = document.getElementById("photofold").value;
var Alias = document.getElementById("commonName").value;

Creating A For Loop To Detect How Many Selects Are On Form

Jul 23, 2005

On my form i have multiple select which all have an id value total1, total2,
total3 etc so i am trying to detect how many there are and then use this to
caculate a total.

Is there a javascript reference to basically go to a form and produce a loop
which will show me how many select drop down boxes there on a form.

Or would i have t use something like

for (var i=0; i < frm.elements.length; ++i) {
form.elements.length
form_field = frm.elements[i]

and then have a nested if to detect if it is select value or has an matching
value ..

When I run the page all that comes up is the start of the table that is written before the script executes. Also is there any way I could use a debugger to catch this on my own? I tried the firefox debugger but it didn't catch anything when I ran it through, maybe I was just doing it wrong.

Creating Massive Grid With Loop Without Freezing?

Oct 14, 2011

I have been struggling with a loop of mine. The loop should create a grid, of 204,000 squares(div's). And the total would create a grid field of 340 pixels by 600 pixels. All div's are sized 1 pixel.The idea is to create a grid, that shows temperature data in a gradient style, like a weather heat map. The data is collected from temperature sensors which are connected to a database.The only problem is that because it's such a massive amount of calculations to be calculated by javaScript, the whole thing freezes. Here is a sample of my code:

Code:

function makeGrid()
{
for (var i = 0; i < 8160; i++)
{

[code]....

Another problem is, the grid should be reloaded every 5 seconds or less.Because that's the interval used by the temp sensors, and for the usage that's planned for the project, its really important that the data is constantly up to date. using another web based language are welcome, as long as they are combinable with PHP or AJAX. Or maybe there is a ready to use library that I dont know of. Couldn't find anything for jQuery.
