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.

the situation: I'm building a web page, and the client wants to have three flash galleries on staggered timing (i.e., the first one loads and runs, 4 seconds later the second loads and runs, 4 seconds later, third one loads and runs).
I've been trying to figure out how to use Javascript to handle the initial delay between each object, and the best I can figure is to use an onLoad to start the first flash (Flash1), and then call out a function with setTimeout to start Flash2 4 seconds after Flash1 loads, and the same thing for Flash3. However, my attempts thus far have failed, and all three load up at the same time.

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.

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?

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');

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.

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?

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" />

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;
}

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.

I have a single webpage that contains information on all 50 U.S. states. There are 50 links at the top to jump down to the state you want, and at the bottom of the information for each state a Back to Top link.
I'm making the Back to Top link into something more complex, and it will require three or four lines of code.
So that I don't have to repeat the code 50 times, and create a burden when I need to edit it, I want to place it in a .js file and call it x. Then below the information for each state I'll simply have:
Does calling code from a .js file 50 times slow down the page load? Which method would load faster?

Is it faster/more beneficial to have two snippets of code be generated by php at 2 different urls and then have a load function for each url? Or have the two snippets on one page, surrounded by id's and then load them that way?

I have some javascript code that does some GET and POST requests that are required. Sometimes it doesn't fully execute for the user because they close or click onto another page before the javascript is completely done. Is there anyway I can let all of the javascript load first and slow down the actual page load of the website.

Any way to create a presentation on a website WITHOUT showing load bars? Background info: it is about photography website where someone after seeing full size picture could click to view it in a room setting. Right now my developer created a presentation where full size picture zooms out then there is a load bar (hideous) and then the presentation starts. So it looks like it is 2 different parts and I would like to make it into one smooth presentation. Btw: would like if possible avoid flash animation due to recent developments on Apple's side.

I know the question begs a question. Why? I have no control over the DB or the Forms. Using 3rd Party based web app. I have this: $(document).ready(function() {
$("#MyButton").click(function (){ $('#CurrentPageInputTextArea').load('jqloadFrom.htm #OtherPageInputTextArea');
});

I'm new to java script and am desperately trying to understand it all. My first question is, I'm trying to create a "rotator" for my companies home page, much like the one on [URL]. And by rotators, I am referring the the deal that right underneath the nav bar that is rotating pics, etc. I found one I like at a different site as well, so I talked to the web developer and he graciously supplied me with the java script code for it. The code is fine, but when I place it in a document, it has the pics and text underneath each other instead if rotating the pics.

I am creating a basic page for a client to allow them to update photo captions on their own. The test page is here: [url]
There are only 4 photos right now for testing, but eventually there will be 100's. The issue I'm having is that only the first image caption is being updated. If I edit the caption for photo #4 and click update, it appears to update, but it actually doesn't. Further testing shows if I change the caption for #1 and click submit on ANY other caption, it updates #1. This makes me think that the jQuery code is only referencing the first form.
I know I could use ID's on the forms and in the jQuery to differentiate the forms, however the form HTML code is generated with PHP and there will be 100's of them. Is there any way for jQuery to determine which form was submitted? I need to be able to tell which form was submitted so I can use that form's caption text to update the photo caption via SQL (photo info stored in an SQL database).
Here's the code from the page. The forms are generated via PHP:

Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.

I've been having a problem that I noticed started yesterday with my site [URL]. At first, I thought it was a Project Wonderful ad problem as that was the first thing I noticed disappearing once the page was fully loaded. Then as I took a look around my site, I began to see it was everything that was javascript was gone at full page load. I did the Google search for every syntax I could think of but have come up empty so I decided to come here to see if someone has encountered this problem and has a solution to offer.
When you first go to the site, all javascript loads, PW ads, amazon widgets, footer copyright date, etc. However, when the page is nearly loaded completely, all things Javascript disappear from the page. I've been trying to see what process point they disappear at but the process loading at the bottom moves by pretty fast. I see a query-yahooapis right before the javascript objects go bye-bye, but can't verify 100% if something may happen right after it. Google search for query-yahooapis doesn't yield anything more than what query-yahooapis is.
I started disabling widgets one at a time, working backwards to see if perhaps one of them was causing the javascript hiding or failure, but even with all widgets disabled, the javascript that remains on the page, disappears when page is fully loaded. I was even considering having javascript load from the footer, but due to the design of wordpress sites, I have to call javascript where needed <script> ... </script> for Project Wonderful ads, widgets, etc. Has anyone encountered javascripts disappearing when page is fully loaded or is there a tool that I am not finding in my Google searches that will allow me to load my web page one process at a time to see which one may be conflicting with javascript when it loads?

I have a main page(html) and an iframe in it.
<html>
<body>
<iframe src="myIframe.html" />
</body>
</html>
In the iframe I have DIV element with a picture/or another element in it. I need to center the DIV element in the iframe, the DIV in the end should be in the center of the iframe(client area), this iframe can be resize, so every time the iframe is resize I need to center the DIV according to the new client area. How I can get the client area and center the DIV? I'm guessing that I will need also the size of the element(picture) to center it, right?

I'm having an issue with the status bar in Mozilla and Netscape showing that
it is still waiting on the page to load even after it is finished. This
problem does NOT occur with IE.
In summary, I am using a onLoad event in the BODY tag to communicate back to
another server each time a page finishes loading. I do this by using a "new
Image()" and setting the .src property to the server. The .src includes a
value in the querystring so I know what request it was that finished
loading.
The challenge here is that the status bar still shows "Transferring data
from www.mysite.com..." despite the image being loaded. It never clears and
leaves the user with the impression that there was a problem loading the
page. My web server logs at the mysite.com show that the browser does
indeed make a request for the image and I get the querystring just fine and
it returns a status of 200 so the image is being found and served ok.
I've tried everything I can think of to solve this and really could use your
help please. Bottom line is that if you use the "new Image" statment from
within the OnLoad event of the Body tag, Netscape and Mozilla never seem to
update the status bar to show "Done" despite it succesfully loading the
image.
Here is a simply snippet you can use to easily reproduce this issue:
