how to you use the result of a function as the argument for another function instead of passing the actual function to it. i.e.
function foo2(){}
function foo(func){}
foo(foo2);
This passes foo2 to foo, can I do foo(foo2()) ? i.e. is the difference between whether a function is passed or evaluated dependent on whether you use "()" after the function name?

I am new to Jquery and would like to know, when we write a Jquery function and pass 'e' or any other word or letter as first argument, what does it represent? Also If I want to pass some parameter to my function along with 'e', how can I pass it?
var xf2; function f1() { if (document.createElement && document.body && document.body.appendChild) { xf2 = new f2(arguments[]); } } I am getting a syntax error in the "new" statement following the [].
How do I pass the variable-length arguments list received by f1 on to f2?
How do i use a function to find the average of the values in an array of numbers passed as argument to a function.(using java script) thank you for your help...
im trying to take an array and create a new array in a function to have it be used in the calculation function. I keep getting undefined when trying to output it. I can pass it directly using Spec(skills, spec, train); inside the function but that defeats the purpose of the function since its not always going to be used.
ive looked for hours on google and its all just variables which i can work fine but for this it will not work.
function Aluvian(){ document.ACCalculator.skillcredits.value = 100; var skills = new Array(); var spec = new Array();
I would like to pass an array to a function but how does the program know which array I would like to choose from?? Lets say I have 3 arrays and I would like to pass array C, to my function. I checked the web but they only show if you have ONLY 1 array but NOT for multiple arrays. How would I even go about doing this??
I am coding a site for a friend who wants an image slideshow on her homepage. I've written a function that requests an array and that should pull in the images at timed intervals. Here is a snippet of the default.js code.

Code: var arrA=new Array("fox.com","nbc.com","abc.com", "google.com"); var arrB=new Array("car","bike","boat", "plane"); var arrC=new Array("1","2","3", "4", "5", "6", "7", "8", "9");
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.
I'm having trouble passing data in an array to a javascript function. I dynamically create a list with edit links on each row and pass the array to the function on each link. Of course, the function only gets the data from the last row, regardless of which link is pressed. Here's the code:
Can you pass an array reference to a constructor? I don't know if it's because the syntax is screwy or it's impossible, but the following doesn't work.
// row constructor with array called fields function RowObject(fields) { this.fields=new Array(); this.fields=fields; }
for example if you have a <span id = "test" onMouseOver ="myfunc(x)>
eg you have lots of differant span id's but you want then all to have a certain background-color with each individual on mouseover event without having to write separate code for each span id eg <span id=" test2"onmouseover ="this.style.background ='red'>....
I have used an object in the past as a function argument, but this was for a plugin that I wrote. Using it in the architecture of a plugin it worked. BUT, this time, I just want to write a normal function, but still use an object to set defaults and pass in changes to those defaults through as a param. Is this possible, or do I have to make this a jQuery function like $.myfunction() ?
How can I create argument defaults for a function? I have this function (the purpose of the lines I included were to set defaults if the user forget to input something simply to prevent an error.
I would like to save some programming space and time by finding another way to set defaults. I saw somewhere that you could set a default in the arguments list Code: function someFunction(aVariable = false) { //some code } But when I try to do this with all my arguments, I get the error: "Missing ) after formal parameters".
New to JS. Have ordered some new books, but need to get somethings going in the mean time. What I wanted to do is to link to a new page having a date range input in the form of 6 text boxes, 2 sets of mm-dd-yy, from and to, where the upon loading the page box 1 of the from would auto focus and then auto tab and then post where php could take over on the server side. Setting up the form and the lay out, no problem. Auto focusing went just like expected using the following code, included because on the next step everything fell apart.
So then the wheels came off and in response, began to simplify what was trying to be done to find where the issues were. As far as I can get working is: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]"> <html> <head> <script type="text/javascript" > window.onload=function() { document.getElementById("input1").focus(); } </script> <script type="text/javascript" > function myFunc() { alert("is this working"); } </script> </head> <body> <input id="input1" name="input1" type="text" onkeyup="myFunc()" maxlength="2" value="type a No." /> </body> </html>
First issue with this: When I first get to the page everything is just as ordered. The focus is on the text box and the default value is "type a No." When I press a key onkeyup, I bring up the alert box with "is this working" in it. But when I refresh the page with the refresh button, after clicking the "ok" on the alert box, the character that was typed in is still displayed. If I use the link to the page, or the URL from the address bar, then the page reloads properly with the default value, "type a No".
How do you get the default textbox value using the refresh button as apposed to reloading the page using a link or from the address bar? Using Firefox 8.0 more important at the moment: If I change the script to pass an argument to the function the script crashes. It does not pull up an alert box and freezes. My guess is that I'm doing something wrong on a concept level. Changed the default value of the text box to " ". Looked like to me there was an issue with the size specification and the default string length as you could only enter in a key stroke by highlighting the text and replacing it.
