curPic = 0;[code]..........
JS Declaring-Wrong Validation Due To Function With Variable Holding Same Valu?
May 21, 2011I am doing a Validation for Form "Text input". If the user leaves the input empty, a function is starting to run. If the field is bigger than 1 - so it doesn't get into the function.
The problem is: The first time, the user left the input empty, function ran, and I got the alert - that's OK. Second time, The user added 10 in the AGE input - And again he gets the Alert - But he should not.
Note: Age input value, returns from a different function (calc) to a var called: result.

Difference Between A Function Pointer And A Function Call?
Mar 11, 2011I'm working through the sitepoint ajax book and had a problem with a particular chunk of code. I eventually tracked down the error and it was being caused because I had:
window.onload = Monitor.init();
instead of:
window.onload = Monitor.init;
Now, one of the sticky threads mentioned that the first is a function call and the second is a function pointer. My questions are:What's the difference between a function call and a function pointer? Why did it cause problems in this particular case? What are the general implications/issues with using one over the other?
Js Function To Find The Difference Between Two Dates?
Apr 5, 2011i've written a js function to find the difference between two dates. the format being used is dd/mm/yyyy hh:mm. The function returns correct value when give one set of values, but go wrong with another set. examples are given below.

Here, it gives 31 days, 6 Hours & 30 Minutes. My code is given below. Also the alert of dates display strange values. Don't know if it is timezone issue.

{
var date1 = new Date(frmtime);

Different Ways To Declare Methods/properties Of An Object
Jul 23, 2005Well, I've been working with JS for three years and have a great experience here. But! I still have no really acceptable answer to the following

Mar 27, 2010(the "code" below is pseudo code, just to get the idea across)
Here's what I currently have:
var bill = new array[20];
var sam = new array[20];
var nancy = new array[20];
var Oscar = new array[20];
I'm assigning objects to them (ie Oscar[5] = new objLabel() This seems like a kluge, however. Here's what I'd like (again, pseudo-code)
var Objects = {bill:null; sam:null; nancy:null; Oscar:null};
var theObject = new Array of Objects[20];
// yes: i know that's wrong... and that's the part I'm having trouble with
so that I can do something like:
[Code]....
Just seems to me that keeping a single array of multiple objects is likely to be less error-prone than multiple arrays of single objects... But I don't have the syntax right... or can it be done in JS? If it's doable, would someone be kind enough to show me how to declare and access that example?
Declaring Parameter As An Array?

Declaring/Initializing Variables Inside Or Outside A Loop?
Apr 30, 2007I've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list[i];
}
or outside a loop routine, like this:
var i;
var name;
for (i=0; i<list; i++)
{
name = list[i];
}
or are both the same....
As a programmer, i always try to practice good programming. I always
thought that by declaring and initializing the variable inside the
loop, i was creating a new memory space every time instead of just 1
time...
What do you think?

JQuery :: Dynamically Declaring Functions - 'array' Variable Contains Strings Representing The Id's Of Different Elements
Oct 12, 2010Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.

Difference Between Object.prototype And Function.prototype?
Nov 25, 2011According to ECMAScript, the root of the prototype chain is Object.Prototype. Each object has an internal property [[Prototype]] that could be another object or NULL.... However, it also says that every function has the Function prototype object: Function.Prototype, it confused me, because a function is an object, for a function object, what is its function prototype and object prototype..For example:
var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype

Difference Between JS And HTML?
Sep 8, 2011I inherited an html demo (used to show customers our product w/o being connected to a server). Was going through the Html files to update the dates and fields and it seems that on some html files, when I change a date <td>08/11/2008 </td> to <td>08/11/2011</td>, save and refesh, I start getting a bunch of JS errors when I try and log back into the demo. I'm not changing anything in the JS files, so I don't understand why the errors are occuring.
I have a bunch of html files to change, and now, no matter which file I change (the dates, sample names, etc), I lose functionality on that particular page.
