Finding If Numbers In A Set Add Up To Another Given Number?
Aug 10, 2009I have what I thought was a fairly simple problem that I would be able to solve on my own, but the code I have found is just too complicated for me to understandI think what i have is similar to the knapsack problem, but I have a really simple version of/~moshe/recor/knapsack/knapsack.html#defSay I have a relatively small array of numbers:2, 2, 3, 3, 4, 4, 5, 5, 5, 6, 7, 8, 9, 10. I just need to verify true or false if a combination of these numbers will add up to 21. The numbers will obviously be changing, ( and in array size), i guess i could just use if statements but it would be stupid and go on for ages.Could anyone point me in the direction of some simple code, or easy to understand way to go about this problem?

Finding A Number In String - RegExp
Aug 13, 2005How can I check if a number exists by itself in this string by using
the RegExp object?
var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
var re = new RegExp( /1/ );

Number / Category Association - Automatically Default Correctly When Put In Just The Number
Jun 16, 2011When updating our agency's webpage daily, [URL] I am looking for a shortcut to save time.. When I update air quality numbers. I have to put the conditions. Ex.. 50 = good 100= moderate etc etc. As you see here(bold and underlined)

View 6 Replies View RelatedScript For Counting A Number - Want Down To Another Number That Resets?
Nov 28, 2011I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?

JQuery :: Replacing Number In Url With Another Number?
Oct 13, 2011What i'm trying to do is replacing the size=180 part of the src (in this case an image) with size=400 so that the images appear larger. I can't simply replace any "180" with "800" because the value might be present in the lid or isbn.So far I've pretty much cut the url up in pieces (I reckon it could be done a lot easier), but I'm stuck with replacing it.[code]

Finding The Height Of A Div
Apr 4, 2006I want to be able to find the height of a div in pixels without defining it in JavaScript. The Div needs to be able to have whatever content in it is required, and it will change without a refresh. I have no idea what could possibly do this, I was hoping somebody with more experience with JavaScript could help me :D
It also really needs to be at least Internet Explorer, Firefox and Opera proof.

Am I barking on a completely wrong tree, is NTLM authentication what I
