Passing A Function As An Argument And Using The Evaluated Functionas An Argument

Nov 30, 2006

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?

Find The Largest Number?

Sep 23, 2010

I am working on my assignment: The assignment is: The process of finding the largest value (i.e., the maximum of a group of values) is used frequently computer applications. Write a Javascript program that input a series of 10 single digit numbers as characters, determines the largest of the number and output XHTML text that displays the largest number. Your program should use 3 variables as follows:

a.) COUNTER: A counter to count to 10 (i.e. to keep track of how many number have been input and to determine when all 10 number have been processed). b.) NUMBER: The current digit input to the program.

c.) LARGEST: The largest number found so far.

Below is my code so far:

Finding Two Or More Matching Largest Values In An Array?

Jul 10, 2010

I am currently writing a program to analyse (to a degree), the points scored in a dance contest. The program mainly works so far. However I am struggling to conclude the program end. Using an if statement, I would like to compute if a dance-off is required, looping through the combinedPointsArray and determining if 2 or more numbers hold the higest score and are equal.The aim is to provide:

Maximum number of combined points

The couples and their combined points

The couples names with the highest points

If two or more couples have equal highest combined points - output whether a dance-off is required.

This is my program so far:

Can JS Pick Up LANG Attrib's ..?

May 29, 2006

I'm new and naive at JS, but use a lot of modified JS snippets in web
design. I'm working on a six-language site for a client right now that has
a small nav bar at the bottom of each template-based page.

I've had success in previous projects, writing out language-specific nav-bar
code nested in a document.write statement; a unique .js file for each
language.

An idea that I came up with that would allow me to create a function that
would cover all languages was this: if javascript could somehow detect the
"lang" attribute of the <html> tag, it could automatically choose which
"langage" js file to reference for my nav bar.

Example, if my german nav bar was in a file, "/scripts/de.js" the function
would pick up "de" from the "lang" attrib in the <html> tag, assign it to a
variable, say "navlang", and render a document.write statement that would
"write" out my script source reference as such:

<script>
document.write('<script src="/scripts/' + navlang +'.js"></script>');
</script>

my problem is I'm not adept enough at JS to write a function that would grab
the LANG attrib of the page .

Random Pick Of A Set Of Colors After A Time Interval?

Sep 27, 2011

I want to have a random change of the border and text color of certain DIVs (with a certian class) after a specific time interval. I managed to get a random color change after the time interval, but I'd like to just have a set of colors, which the random generator can choose from. So here's my code:

Code:

<script type="text/javascript">
$(document).ready(function(){
var intervalId = setInterval(function() {
int i = (int)(Math.random() * 4);

[Code].....

So "i" can be a number from 0 to 3 and depending on this number, the variable "col" is a specific colorvalue which the border and text color will animate to. That was my thought, but something about the random color generator doesn't work
