I guess the variable puzzleHolder isn't available within the scope of the function checkElement. You're errorconsole should throw an error like 'undefined variable: puzzleHolder'.

You can calculate the row number and the value of i_2.
row number = Math.floor(i/9)
i_2 = -9+i%9

I'm wondering why you're loop is running to i<=grid.length, instead of i<grid.length though.

Yes, add the input boxes and call the function calculate_quarter, for the four quarters you need.
1st argument is an array with the names of the month input boxes for that quarter.
2nd argument is...

If you're repeating alot of code with different variable, you should try to make functions out of it.


function SumAverage(){

function calculate_quarter(months, categories, avgNode,...

It might seem confusing at first, but it helps to recognize those function in debuggers.

The outer (closure) function is self-executing and returning the inner the inner function. The global isPrime becomes the inner isPrime function.
The scope of the outer function is preserved and can...

Yes, that's correct

That console is a little confusing. The referenced object is an instance of the isPrime constructor. A contructor could be seen as a template to create objects.



function Person(name){

Since function declarations are executed before other statements, the conclusion from above example doesn't seem right to me.
The javascript interpreter runs it like:


function isPrime(){var...

IF you need to support older browsers you can do


function bind(func, object) {
return function(){
return func.apply(object, arguments);
};
};

parag.addEventListener("click",...

When you use document.getElementById on a non existing ID it returns 'null', not 'undefined'.


if(document.getElementById('testdiv') != null) {
// exists
} else {
// doesn't exist
}

You should use a 'while' loop instead of a 'do while' loop. The 'do while' will execute the code block once, before testing the condition.

When a function is invoked by an event 'this' refers to the invoking element, or to the 'window' object depending on the way the function is referred to by the event....

Should look like this:

function sumMatrix(matrix){
var row,
col,
rowLength = matrix.length,
colLength = matrix[0].length,
rowTotals = new Array(rowLength);
...

The second loop should be:

for(y=0; y<=personarr[x].length; y++)

Seems IE is testing the arguments for your window.doScroll method, as if they were given to it's own document.documentElement.doScroll method.
Giving you function a different name should fix your...

Code between scripttags pointing to an external file isn't executed.



<script type="text/javascript" src="/media/js/comments/comments-controller.js"></script>

<script type="text/javascript"...

Since colorArray.length gives 3, and the last index of the array is 2 since it starts at 0, i <= colorArray.length should be i < colorArray.length instead.
And there is a bracket to many in the if...

Here's another example.



// first create a Person constructor, which takes two arguments and sets them as properties of the created instance
function Person(name, age){
this.name = name;

All you need to do is call DragHandler.attach with the element as an argument, when the DOM is done loading.
There's no need to attach events to the element yourself.


<script>
window.onload =...

It's because IE versions lower than 9 convert bgColor="red" to bgColor="#ff0000", so you should test for that aswell. Or add descriptive classes to your cells so you can tell them apart in your...

function multiply(a, b) {
return a * b;
};

function partial(func) {
var slice = Array.prototype.slice;
var fixedArgs = slice.call(arguments, 1);
return function(){

That old code will only run in quirksmode.

Try this modernized version:

You're browsers are fine, if you scroll down a bit IE doesn't zoom in on the thumbnails anymore. You should try getting document.documentElement.scrollTop instead.

It's a problem with the version of mootools you're using. You could try with the latest version.
Or change


a="<"+a+">";}return document.id(this.createElement(a)).set(b);
