Usually I have various JavaScript functions for common functionality on my pages (i.e. select all, export, etc.). Typically I will create a common.js file and place these functions within it. Is there any advantage to create a client side object which encapsulates this functionality such that I'd use something lik common.SelectAll() or something similar?
Not sure if there is a best practice peeps follow for this or not.
This has really got me stuck. Below is a distillation of my problem:
This is my function:
function Clear(form) {
???.checked = false;
}
<form name="myform">
[Code]....
How do I execute the function to clear the checkbox the moment it is clicked? How do I reference that specific checkbox, when there are multiple checkboxes with the same "name"?
The rules (the above is a simplified version of my actual problem. There is much more to my script, which means other possible solutions cannot be considered):
1. I am aware of onclick="this.checked=false", but I cannot use it.
2. The ID for the checkbox is dynamically generated, whereas the entire onclick command must be the same for all checkboxes.
3. All checkboxes must have the same name, and the name must have square brackets.
4. "this.form" must be in the onClick, as it is used by the rest of the function.
How would I go about copying all the prototype functions AND the constructor from one object into another object, and then call them?
I know I can use this.example.call(this), but that's not an acceptable solution. I want to deploy this style over dozens, potentially hundreds of objects.
Here is a link to my gallery: [URL] Here is a screencap of my problem: [URL] This just seems to randomly happen sometimes, and I can't figure out why. Very rarely, it will be one or two of the thumbnails that's lower, but I didn't get a screencap and haven't been able to get it to happen again. The problem with the main image occurs frequently after clearing the cache in Safari. I'm totally stumped, because other times it loads just fine, and seems to always be fine when the page is reloaded or a thumbnail is clicked.

I've been going through the documentation for the deferred objects API, and one thing that's still not clear to me is : what jQuery functions are returning a deferred object?
The documentation seems to say that jQuery.ajax() and the animation functions like jQuery.fadeIn() does (what about jQuery UI effects?), but the pages for those functions say they return a jqXHR object and a plain jQuery object.

I am using objects in JS and I am trying to add draggable() into a DIV that works when I move the function out of the object context.
Example:
Code:
That does not work. However, if I do this:
Code:
Then it will work... because the draggable() function is not within the object.
I need this to work within the object, because I will have several DIVs associated with objects and I need them to have draggable() in specific cases.
One of the great annoyances I have with JavaScript is the lack of a good
consistent code library. Oh, there are a few code libraries scattered
around for doing various things. The problem is that each of them have
their own way of doing things. If we want to use more than one library
at a time, we often end up duplicating code and working with different
interfaces and practices that aren't necessarily compatible with each
other...
So... isn't it about time that we have a Common JavaScript Framework?
I'm thinking of a standardised code library, mostly (but not entirely)
built from the free code that is already out there. (I'm thinking of a
LGPL core with independantly licensed extensions.)
I know of a few very cool projects that aim to make JavaScript
development easier, more professional and to bridge the gap between
browsers and environments. (To name a few: DynAPI, DOMAPI, Sarissa,
13th parallels' library, netWindows, bindows, ActiveUI, f(m).) But I
don't know of any effort to bring all of these features into one common
framework. Can we do anything about this?
I'm not exactly proposing that we form a group to design and implement a
complete framework. I just think that, us, JavaScript developers should
talk to each other more and agree on a few things. Then, I imagine
being able to access this centralized, well designed library that is
ready for serious (and less serious) development and the dream goes on...
I have been working with JS (client and server) for some years now and
I'd like to bring more consistency to my code and spend less time
writing lower level code. So I may be writing this email more out of
wishful thinking than determined action. In any ways, I remain
interested to support any effort that would lead me to better, well
designed, programming.
Is there a way to place a code that will be executed any time any button is pressed or any hyperlink is clicked? I don't want to write or call this code on every button press. Something similar to java's base class functionality that is extended by child classes? In my project ,I have to manage users to access my app - and if a user is deleted and that same user is having app open in one of her browser windows and she performs any action,she should be redirected to login screen.
I am thinking of writing a code that will check if user exists in the db or not and then put it in javascript file at a common place so that it gets executed everytime user presses a button(or does any other action). I am using jquery and Direct Web remoting framework in my app.
what character occurs most frequently in a textarea. Do I really have to store every single character in an array and then sort it? Is there a Regular Expression for this?

I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper()

I have come across an issue that only happens with IE.I have a custom save function that is designed to handle different ajax submits but I will simplify it for debugging. The issue is that once I make a submit everthing is fine at first. Then once I try to submit a second time it craps out. I am checking to see if there is an onsubmit function and then executing it like so before continuing. After the inital submit it is no longer found. When I alert the typeof document on the form it returns object but when I add the onsubmit it says object expected or object is null or undefined.
Code:
function secureBarSubmit(formId)
{
alert(typeof document.getElementById(formId)); // object always
alert(typeof document.getElementById(formId).onsubmit); // func first time then it is broken
