## Display Negative Number As A Positive?

Dec 20, 2005

I have a calculated value that is negative, which I need to display in a javacript prompt as positive. In ColdFusion, there is a function called ABS(), which gives you the absolute value of the number in question, so ABS(-5) = 5. Is there something similar in javascript? If no, how would I display a negative number without it's negative sign? Again, this is only for display purposes withing an alert.

## Number / Category Association - Automatically Default Correctly When Put In Just The Number

## Script For Counting A Number - Want Down To Another Number That Resets?

Nov 28, 2011

I 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?

## Regular Expressions Replace - Detect The Number "2" And Put It Superscripted Past The Number 5

Jan 3, 2011

Formerly I've been replacing characters with javascript using the following code.
