How To Create An Arbitrary Object At Runtime?
Jul 23, 2005Can anyone suggest how to create an arbitrary object at runtime
WITHOUT using the deprecated eval() function. The eval() method works
ok (see below), but is not ideal.
function Client() { }
Client.prototype.fullname = "John Smith";
var s = "Client";
eval("var o = new " + s + "();");
alert(o.fullname);
Note: I want the type name of the object to be represented as a string
(in this case "Client" -- this is a non-negotiable requirement).
I also tried the following (which appears to fail):
function Client() { }
Client.prototype.fullname = "John Smith";
var s = "Client";
var o = new Object();
o.construct = s;
alert(o.fullname);
eval() is handy but not future-proof, so any suggestions would be
welcome.

Dynamically Create And Delete A Function At Runtime?
Jul 1, 2010I'm using a 3rd party API that does asynchronous requests for me and directs response to a callback that I specify. Since my code can issue multiple requests concurrently I want some mechanism to match each response to the specific request e.g. attach a unique ID to be returned with the response. The 3rd party API does not allow me to attach any user context to the request so the only way I could figure out how to do this was to dynamically generate a callback function per request and embed the unique id in the body of that function. When the callback is invoked I can use the information to complete my handling of the response.
1) First of all if anybody has a better idea on how to achieve the above without dynamically generating script I'd be happy to hear it.2) Regardless of (1), if using my proposed method repeatedly I will be generating a lot of garbage over time, so I want to clean up after myself. Meaning, to delete the dynamic callback after it completes. Below is an example of how I wanted to do it, but it seems not to work:
Code:
function CreateDynamicCallback(callID)
{

Even I do document.write('hello world'); it still has the same error.

{var obj = InputForm.elements[i];

JQuery :: Microsoft JScript Runtime Error: 'parentNode' Is Null Or Not An Object
Jan 6, 2012i am starting a new project using Visual Studio 2010 ad using the same jQuery filesofa previous project that didn't cause errors.Visaul Studio always raisesthe same error in jquery.min.js Microsoft JScript runtime error: 'parentNode' is null or not an object I click on "continue" for that error message and the page loads fine and I don't see the javascript error icon in the bottom left corner of IE. This really baffles me. When I launch the application using Firefox I don't get an error in Visual Studio. Does anyone have any tips on debugging this jquery.min.js ? Has anyone seen something similar. Just starting this project and I already lost 12 hours troubleshooting this problem. I've looked at the html code and I can't see anything that would cause an error Here is the HTML.

Why Does Alerting A Record Create A Dialogue Box With Only [object Object] Inside It
Nov 4, 2009every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
Create A New Template Object That Inherits From The Built In Date Object
Oct 6, 2011Is there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.

Create An Object On The Fly?
Nov 23, 2011I have a select with a OnChange Function. I would like to know how to create a different object depending on the selection on the Select.
Example:
MySelect have Option 1 and Option 2, so
If (Myselect.value == Option 1)
{Create Object 1}
If (Myselect.value == Option 2)
{Create Object 2}
I'm using the object under <body> and it's working, but when I'm trying to use it under a <script> does not work.
This is the object I'm trying to create: (It is a map) so what I'm trying is to change the values or map depending on the selection of the Select.
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="900" height="600" id="zoom_map" align="top">

Create New Blank Xml Object?
May 11, 2010I know I can use the functions like parseFromString() to access and modify an existing XML documents, but is it possible to use JavaScript to create a blank xml document?
I want to take data entered into the client, package it up as XML and use ajax to transmit it to the server. So far I've written my own class to create a simple xml document, but I'd like to do it properly with the inbuilt functions.

Ajax :: Create An Xmlhttprequest Object ?
May 7, 2011I am trying to create an xmlhttprequest object to update the shopping cart on my web page without submitting the entire page to the server for processing. However, what I have done so far is not working. All that is happening when I click the "update cart" button is the page sort of flashes and the check marks in the remove item check boxes disappear. The first code snippet is the "traditional" way of submitting the whole page to the server for processing - and it works. The second snippet is what I have done to try and implement AJAX to submit only the shopping cart - and it does not work.

Create A Date Object From An ISO8601string?
Jun 15, 2011I was wondering how you would create a javascript Date object from an ISO8601 string? We have done this successfully in FF4, but not IE.
If we try the following in FF4 it works:
alert(new Date("20091107T12:15:00))
In IE it returns:
'NaN'
What would be the Date standard used in JavaScript and AJAX from the server to the client? We were thinking about using UTC
Create An Object That Will Update Itself At A Set Interval?
Oct 11, 2011I'm trying to create an object that will update itself at a set interval, but I'm having a scope issue when using the "setInterval" or "setTimeout" function.
[Code]...
But I get the same result. Ultimately, I'd rather have the setTimeout (or setInterval) to be within the object, so that each instance of the object will fire the update on itself. I had a similar issue in this thread but I can't seem to figure out how to adapt it for this instance.

Create Image Object From Binary Data?
Mar 2, 2009Im trying to implement dynamic images on my site. Basically, there is a list box, and when the user selects an option, it calls a service that streams back a base64 encoded image that will be the preview of what they're looking at.in FF you can do this: img.src = "data:image/png;base64," + args ; This doesnt work for IE. from what ive learned, IE doesnt support this type of inline coding.
I was thinking that maybe the next best solution would be to convert the base64 back into binary, and set the new image object to that source. something like this:
Code:
var img = new image();
img.source = binarydata;
now obviously, img.source isnt a real method. but i would like to be ale to set the binary data as the image.
possiblities: Is there anyway to save that binary as a file on the client? and then be able to reference that file as the picture img.src = "images/" + newfilename;
Some other alternatives is to stream back a reference on the server to get the picture, this would require two callbacks, which i dont want.
Also, there is a method of turning the image into a big array of HTMl elements, and each element holds a color, being a pixel. im not doing that, that is the biggest hack job i have ever seen.
Difference Between Privileged Methods And Object.create
Apr 13, 2010I'm attempting to understand the use of privileged methods when used with Object.create. I put together a quick demo (code below) that shows what happens when I use Object.create to create a new object based on one that has a privileged method. The outcome is not pleasant, as changing the value in the first object also changes it in the second. Unless I am reading Crockford's articles incorrectly, this makes Object.create almost useless for anything but objects that have only public members.
I've seen many JavaScript programmers use closures extensively to create private members, and that still holds to be a good programming practice. However I still can't find an elegant way to create inheritance in combination with closures in JavaScript, given downfalls such as the one I mentioned above.With all of that said I still think Crockford has a nice way of programming, creating factory functions that produce objects, staying away from the prototype property and making the language look more functional.
Here's the code to demonstrate what I'm referring to. Firebug needs to be enabled to view the console.debug output, otherwise convert them to alerts.
if (typeof Object.create !== 'function') {
Object.create = function (o) {
function F() {}
