## How Do I Convert A Number: From Dec To Hex Into A String?

Sep 9, 2006

Now I need to convert a number(decimal) into a hex.string. I want to pass my blurit() two colors and have it start at color one and step its way to color two based on a determined step. I need to convert the new color to a hex string to be used to control the color of text. This is a rough example of what I am doing:

function blurit(color1, color2) {
colorstep= (color2-color1) /10; clr=color;

test.innerHTML+= '<font color="#' +dex(clr) +'">'

## Convert A Number To A String?

Apr 3, 2010

I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.

Code:
function highlight(star) {
var num = Number(star.id);
for (i = 0; i < num; i++)

[Code].....

I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried

var id = String(i+1);

but this didn't work either.

what have I gotten wrong?

## Why Does 1+1 Equal 11? Or How Do I Convert A String To A Number?

Sep 2, 2006

Javascript variables are loosely typed: the conversion between a
string and a number happens automatically. Since plus (+) is also
used as in string concatenation, `` &#391;' + 1 '' is equal to `` &#3911;' '': the
String deciding what + does. To overcome this, first convert the
string to a number. For example:

## Finding A Number In String - RegExp

Aug 13, 2005

How 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/ );

## 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?
