# 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?

When 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)

## JQuery :: Replacing Number In Url With Another Number?

Oct 13, 2011

What 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]

## 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.

paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");

So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>

## Counter (up) From A Preset Number And Date To A Second Preset Number And Date?

May 10, 2011

I am delving into the coding world and while I understand the basic principle of cookies, conditional statements, arrays, etc...I have looked around the web and this forum with little success. If the situation below is too complicated, I would really appreciate even a shove in the right direction regarding the logic.How could I show a preset counter which counts up from a preset, beginning number toward a preset, end number? I imagine the increment and speed is set be the difference between the two numbers and a timeframe.

:confused: Assumptions:I would rather not set the increment but edit the end number to show a steady increase. As I update that number, the increment adapts dynamically. I would want the number/script to be useful, so it should not refresh to the beginning number on each page load (i.e. num=0). When a visitor comes to the page, it must seem like the counter has been steadily been increasing in their absence.Coke or Pesi did something similar one time regarding cans sold to date (doubt it was plugged into a DB somewhere but rather based on a steady sales figure) and it was pretty cool.

## Return Says NaN (Not A Number)?

Aug 1, 2009

i am using ajax but this is the problem in js it is giving me a NaN when i goto check the output. on two different servers two different responses on my localhost test environment i am getting the correct info and on the server online i get NaN response. i am using this to set the width of my hp bar

Code:
document.getElementById("ehpBar").style.width=count1+"%";
and count1 looks like this
Code:
var count1 = hp/basehp*100;

i have tried rounding it and everything and i just get the same stupid NaN error. I can use each variable by itself and it outputs the correct number on both servers and then when i try to divide it NaN on one server and works perfectly on the other. I know it is probably something simple i am just missing it.

## Get First Digits In A Number?

Jul 19, 2010

This is probably the stupidest question ever. I know in java you can take advantage of a number being an int (not double) and divide by something without getting a remainder. But in javascript you dont declare what kind of variable something is.

So my problem is: Given any double or triple digit number, how do i get all but the last digit. Like if i have 13, I need to make an int with 1. If it's 103 i need one with 10.
