Array, Hashtable Or Binary Tree?
Dec 13, 2005I am looking for the best performing solution for modifying and
iterating an object graph in JavaScript. I have outlined below a
simplified example of the object model and examples of how I will be
using this graph.
Object model:
Two objects, [BadApples] and [GoodApples] each contains a collection of
[Apple] items (500 max). [Apple] simply has an ID and a name.
Requirements:
A quick way of determining whether a certain apple exists in either
[GoodApples] or [BadApples] (by ID).
A quick way of iterating through [GoodApples] and [BadApples] in order
to update the web page.
A way of moving a certain [Apple] (by ID) between [GoodApples] and
[BadApples].
I currently have this implemented using arrays, but iterating these
arrays is expensive. Is there an implementation of a binary-tree for
JavaScript? The real-world application may contain many hundreds of
nodes, and performance is crucial.
Matrix Implementation In JS
Jun 4, 2004This is my implementation of an n x m matrix in JS:
var n=parseInt(prompt("n:",1));
var m=parseInt(prompt("m:",1));
function array(){
this.length=m+1;
for (var i=1;i<=m;i++)
this[i]=0;
}
function matrix(){
this.length=n+1;
for (var i=1;i<=n;i++)
this[i]=new array;
}
var a = new matrix();

JQuery :: IGoogle Like UI Implementation?
Jun 22, 2010I have a request to implement iGoogle like UI features, specifically, the drag/drop module boxes, and configurable elements for each module box. Currently, I have existing module box with all the forms and elements (backend support for them too). But they are not drag and droppable, and not configurable.My questions are: 1. Do I need backend engineering involved in this implementation? my understanding is: it's pretty much front end UI work and backend already provided all the form elements, backend DB, etc. for this.But my only concern is: how can the system save the user's configuration when they login the next time? Do I need backend engineering's help for this? related DB setup, java class files, etc? 2. is there any jquery UI API/plugin I can take advantage of so that I don't have to do everything from scratch?

View 1 Replies View RelatedCross Browser Shiftkey Implementation
Oct 4, 2005've been looking to implement a function which allows me to populate 2 form fields from an onClick event. I needed to be able to fill/modify one field on a single click and the other on a shift-click. This is all working fine but only for IE 5.2/Safari/Opera 8.02 but fails in Camino(Gecko). I don't have much experience in working across the different DOMs, I do know that I will need to use a different variation of the shiftkey (e.shiftkey?) and for NS4 (e.modifiers?); but I really am not certain as how to handle these correctly. Initial testing has been with limited success.
Could anyone give me some practical pointers to handle the 'shiftkey' for Gecko/Netscape4? (Gecko is more critical)
Current code as below:
function fillform(txt) {
if (event.shiftKey)
{event.returnValue = false;
alert('shift on');
MM_changeProp('fieldone','','value',txt,'INPUT/TEXT')}
else {alert('click only');
MM_changeProp('fieldtwo','','value',txt,'INPUT/TEXT')}
}
<map name="mymap" id="map16">
<area shape="rect" coords="100,14,191,41"
href="#" onClick="fillform('mytext')">
</map>
Ajax :: Updater Implementation Does Not Work / Fix It?
Oct 12, 2009I wanna make a live-error-checking sign up form.
So these are the codes
this is the php file which return echos to the js files (there's no error here, I've posted this so you know what it's all about) [code]...
if a user writes in the text box for nickname a nickname that is already registred then in a text box near the input text it will appear something like : "This Login name is already taken!"
and so on for every field (firstname, lastname...)
I have done this previously with classic ajax tehnics (that with onreadystatechanged) and it worked. But this version does not. Can you spot the error here?

View 6 Replies View RelatedJavascript Implementation Of XMLHTTP And SOAP Objects?
Jul 23, 2005I don't know enough about the technology yet to know whether this is a ridiculous question-- but is there no cross-browser javascript implementation of XMLHTTP and SOAP for use in calling web services?
It looks as though MSFT expects the client to be running Windows and ActiveX and have certain DLLs installed; and Mozilla seems to have its own implementation of SOAP. Is it
possible to implement these protocols in pure client-side javascript?
AJAX :: Implementation Of Virtual Mode In ListView?

JQuery :: Ajax Request And Get The Response Back From Implementation - .toggle() Does Not Work
Apr 7, 2010I have a problem which I am not able to solve. I read a lot and tried many things but without being successful. Mhh.. The problem I struggle with is a simple .toggle() of a DIV. This is working fine. But now I do an ajax request and get the response back from my javascript ajax implementation (I'm using ajax anywhere). Within this implementation I work inside a callback routine which makes it possible accessing the response before updateing the DOM. Inside this routine I want to .toggle() but this is not working. It happens just nothing. I also do not get any javascript errors. As soon as the request is completly done I am able to .toggle() again.
When I am accessing the DIV by using jquery ($('#div_id')) it is referenced to the correct object within de document. Only the .toggle() does not work. .hide() for example is working fine.
Background: I am doing this like this, because I want to know if the response contains validation erros. If so I leave the DIV with the form inside as it is an highlight the error. Otherwise (no errors) I close the div with .toggle(), update the dom with the new form and open the DIV again.
Many reports are facing a problem that they lose the jquery binding. But this is not my problem as far as I understand.
Call A Function Within A (function() {...})(); Implementation
Oct 11, 2006How do you call a function within an implementation that's in this form:
(function () {
var G_vmlCanvasManager_ = {
init: function() {
...
},
initElement: function (el) {
...
}
...
})();
I'm trying to call the initElement function that's within excanvas.js
which its comment says is public.
If I try calling initElement(c) or G_vmlCanvasManager_.initElement(c) IE
gives errors.
