# Add By A Percentage Rather Than A Number?

Nov 2, 2011

I am using a JavaScript price calculator. Right now it does everything I need except for one thing.

If you look at the "type" field, they can choose either woven or printed. Right now, if they choose "woven" it adds 6 cents to to the total as you can see in this portion of the code:

if (theForm.select.value=="woven") {
priceeach+=0.06;

Rather than 0.06, how do I get it to add a percentage--say 20%

The form is located here: [URL]

## Calculate The Percentage Of A Number?

Apr 12, 2011

I want to calculate the percentage of a number, but I'm getting a really weird result. In the following code f is equal to 3 and x.length is equal to 8. The part that isn't working is emphasised in bold. Basically 3/8 * 100 should result in 37.5 but the result I am getting with the following code is 7934570.3125. How do you calculate this percentage in Javascript?

function displaymember()
{
var m = 1;

## Working Out Percentage

Jun 9, 2006

I am going to use javascript to calculate a value depending on what the user selects from a dropdown menu.

I have 2 columns in a table and a dropdown menu. The value in the 2nd column is going to be calculated by taking a percentage of the number that is hardcoded in the 1st column.

The user will select an option from the drop down e.g. 10% 20% 30% etc... and the value in the 2nd column will be calculated according to the percentage of the value in the 1st column.

## JQuery :: Animate With A Percentage Placed Div?

Jan 26, 2010

I have divs on a page that are placed in the center with something like
width:100px;height:100px;position:fixed;top:50%;left:50%;margin:-50px, 0, 0, -50px;
I want to animate this div to the bottom left (similar tominimizingeffect on windows)

I am trying to use.animate({

opacity: 0.25,

left: '10px',
bottom: '10px';
height: 'toggle'
}, 5000);

However when I activate this it simply jumps (or glitches) to that position, the opacity and height animate perfectly.

## Calculating Percentage In A Form?

Mar 23, 2010

I am writing a form and doing a bunch of calculations one of which is a percentage based on the value selected. I am returning a correct result for two of the values but for the other two I am not.The 'discount' value is what I am looking for. It should return as 0 for values of 1 but it is doing the math as though it is multiplying by 1. And again for the value of 6 it should be 10% but is taking the value as 4.6 or something.Code is below I've included all of it (sorry) for better ease of understanding the math that is happening:

HTML Code:

<form id="form1" action="" method="get">

## Style.filter Percentage To Hex?

May 27, 2011

I'm working with a style.filter related function.Some of my function appear as ...

Code:

document.getElementById('audio').style.filter = 'progid:DXImageTransform.Microsoft.gradient(startColorstr=#A8' + c.substring(1) + ',endColorstr=#A8' + c.substring(1) + ')';

Everything is working but I'm trying to replace the "A8" part with a percentage typed in by the viewer.The percentage is simply a non-decimal number between 0 and 100 typed into a box.I know how to grab the value of the box (again, it's 0-100) but how do I convert that number into it's "A8" equivalent?

## Changing Image Size In Percentage?

Dec 1, 2011

I am implementing a zoom in feature, but actually tricking the user as a full screen image is simply being stretched.

I plan to apply it to several pages, and don't really fancy working out the pixels for each.

I believe that if you simply put width: 150% height 150% it will change the image size relative to the browser. I don't want that, I want it relative to the original image size. Could I do sort of height*1.5 or something? How would I write that if so?

<script>
\$('#in').click(function() {
\$('#drag img').animate({
width: '150%',

## Sizing A New Window By Percentage Of Image Size?

Mar 25, 2009

I didn't write much of this code, but basically, it opens an image in a new window. The problem is that the new window can either be the whole page, or a certain set size. I would like to make the window height and width determined not by a pixel number, but by a percentage of the size of the image I am opening in the new window.

here is the piece of code I think is pertinant.

// Strip file name from image src
var spath=targ.getAttribute('src');
wholePathLength=spath.length;
strippedPathLength=spath.substring(0,spath.lastIndexOf("/")).length;

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

Jun 16, 2011

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)

## 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?
