I have a question about my array. I have an array called numberarray with 20 elements and i want it to be accepted into a function as a parameter? But i only want the first 10 to be accepted. Does anyone know exactly how i would go about doing this in my function?

I was having some trouble with 2D arrays (or array of arrays). Essentially, the array has 100 rows, with two columns. The first column of every row holds a name, and the second holds a sales amount. With the use of a do while loop, the user can continuously add up to 100 names and sales amounts. After all the information the user wishes to add is stored into the 2D array I'm attempting to pass that very same 2D array as a parameter to a function called printRow as can be seen in the code below: Note: the function call and the actual function are found in two separate javascripts.

Captions for the images are called from the parameters of the main function and delivered into a span or div tag with the appropriate id. A very important part of what needs to be in the captions is text compiled by a separate function, in the project library.I've tried this with and without curly, square and round brackets, with and without semicolons and quotes- all with varying results. Sometimes the function is called, but it appears at the very top of the page and nowhere near the proper <span> tag.
addImage(a,b,c,d);
// filename, image name and caption are in a, b and c.
// d is the variable where I need to write my other function...
addRef(t,s);
// I need to put addRef in the d parameter of addImage.
Is there any way to pass a function(with its parameters) to another function using a parameter?

I have a simple JS function that I want to return a true or false value
based on the parameter passed in. At this point of time I receive the
error "'True' is undefined". Here is my code below.
JS Function -
function ShowSpecifiedPeriod(pShowPeriod){
document.mfperformance.ShowPeriod.value = pShowPeriod
document.mfperformance.method = 'get'
document.mfperformance.action = 'composite_requestdata.asp'
document.mfperformance.submit();
}
ASP Event Handler -
onclick="ShowSpecifiedPeriod(<%If bShowPeriod = false then
Response.Write true else Response.Write false%>)"
The ASP variable bShowPeriod is set based on the hidden form field
"ShowPeriod" and the initial value is set to false.
More than likely this has to do with the boolean Parameter but I am not
sure how to handle this in JS. I have tried the following but receive
the same results.
function ShowSpecifiedPeriod(boolean pShowPeriod) - Same Error
function ShowSpecifiedPeriod(pShowPeriod boolean) - Same Error
Please let me know what I am doing wrong here.

I'm adding buttons to my google map through a loop. I pass some parameters, and the addButtons() function creates the buttons. How can I pass the "task" for the button to the function? In the addDomListener line below, I'm now writing the function name literally, I'd like find a way with a parameter.
// The loop...
for (i=0;i<=4;i++) {

I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.
Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.
I've been searching now for quite a while trying to look for a way to give the default value to a function argument if it's not given. For example, in php one would do the follow:
function func_name(foo = 'default') {
...
}
In the above case, if foo isn't supplied while calling for the function, then foo would default to 'default'. I have tried that in javascript, but it doesn't appear to be working, so I am wondering how should I do this in javascript?
I have a js file which will open a web site.
Code:

can i pass a hash as a function parameter. ive seen it been used
before but i can't figure out how to do it.
i would like to call a function like this for example
doSomething({variable1:"blabla",variable2:"blabla"});
how would function doSomething be written for this to work.
I would also like the hash to be optional and the variables in the
hash to be optional.
meaning i should also be able to call doSomething(); with no variables
in it.
I tried to use setInterval like this but it did not work:
setInterval ( removeitem (theitem)

the function without the setInterval is

{
theitem.style.display="none";
}

The line that I commented out was an attempt at getting a variable that had the value of the image-id, but it doesn't work.
I am trying to pass a variable into document.getElementById and it is returning a null value. I am hoping someone can identify my error and point it out. The frustrating thing is, I got it to work and then changed the code and screwed it up again...ugh.

FireBug shows the problem is with the first line of the function - it's assigning myDiv null instead of what I want it to assign it (div#myDiv1 I think).
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?

I have an image with an onclick function and parameters 0, 1. I want to change the parameters of the onclick function through the same function?
<img id="down0" onclick=swap(0,1) />
<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}

Normally it should change the onclick to swap(1, 2) but it remains 0, 1.
I have a good understanding of javascript although I am new to working xml. So I am having a problem getting javascript to recognize that my parameter value in my function call is an attribute in my xml. I called the js function like this:

Here is my js function:
var category;
function ebookCategory(category) {
