Rounding Off Percentage Values
Oct 27, 2010
I have a problem in my code which is as follows:
Code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
[code]....
My problem here is that I am calculating the percentage values of a whole number and storing those values in text boxes respectively through javascript function.Now,what I need is that I want to round all the values to integer value such that the sum of integer values is equal to the final value.

I have to round a fractional value from a form input to either 0, 25, 50 or 75. I have succesfully tested the value and stripped the decimal place. If the value is for example .1, I round it to 0. If the value is say .2, I round it to .25. My problem is that when the value is > .75, my function is returning undefined. For the sake of brevity I will include only the relevant code.
var increments = new Array(0,25,50,75);
CharBefore = parseFloat(CharBefore); //the whole number
CharAfter = parseFloat(CharAfter); //the decimal
var x = parseFloat(increments.length - 1) ;
for ( i = 0; i <= x ; i++ ) {
var testValue = parseFloat(increments[i]);
if (CharAfter > testValue) { continue ; }
else {
var lowerValue = parseFloat(increments[i-1]);
if ((CharAfter > testValue) && (i==x)) {
median = (testValue + 100)/2 ;
if (CharAfter >= median) {
CharAfter = Ɔ'
CharBefore++;} //round up to next whole number
else { CharAfter = testValue; }
}
else {
median = (testValue + lowerValue)/2 ;
if (CharAfter >= median) { CharAfter = testValue; }
else { CharAfter = lowerValue; }
}
return CharBefore + '.' + CharAfter;
break;
}
} // End for loop

So just found out the problem I was having, and came up with a solution (bandaid really) but would like to know if anyone else has run into this and what they did.
Code JavaScript:
var left_margin = $(this).css('margin-left').replace(/D/g,'');
So the above, get the left margin of the object, strip all but numbers and store into a variable. Easy, right? Here's what happened. Inserted the object into the DOM, Chrome returned 212px, which was converted to 212�*fine. Firefox on the other hand returned 212.5px, which was converted to 2125� not fine. I'm centering the element on the screen based on this number, so the additional 2000ish pixels is WAY off. My solution was to increase one of my initial values a single pixel in which both browsers return 213px�*but like I said this is only a bandaid solution. Not really understanding the value of .5 pixel, but looking into that. Is there a rounding function in jquery? Javascript I would have to strip the px from the string, convert to integer and THEN round.

I need help with figuring out how to round to the nearest 5th number.For example, if I had a variable with the value of 42, how can I round that up to 45; another example being 37 to 40.

I have a half dozen bookmarks for rounded corner plugins, but am wondering if there's a "state of the art" plugin kicking any booty on that these days? What I'd *really* like is to just be able to set -moz border radiuses in CSS and have a plugin magically use those to create rounded corners in IE and Safari (IE mainly... using excanvas or something with it is fine, too).

Suppose I do (5 * 0.039) + 0.59, then the result is 0.7849999999999999 - but I want to round it upwards and should have only 3 digits after decimal point. I found out that using toFixed(3) will get it to be 0.785, but the problem is that it add x.x00 for some numbers where there aren't much decimal numbers. Is there a way I can remove the 0's?

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]

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.

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.

I am having an issue with converting my decimal to a percentage. Below is my code:
(cost * .06) is where the issue is
var cost = prompt("What is the cost of your purchase?", "")
document.write("Return Value: "+cost,("<br />"));
var salestax = cost * .06
document.write("Return Value: "+salestax,("<br />"));
var total = cost + salestax
document.write(cost + salestax);

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;

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">
<fieldset>

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?

I am wondering if anybody can provide statistics what is percentage of visitors with disabled JavaScript.
Even more interesting would be statistics of users with disabled JavaScript making a purchase. I am more likely to purchase from my home than from work and I think the disabled JS is mostly result of IT dept. policies.
Is e-commerce site missing much if requires JavaScript?

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%',

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;

I am trying to customize this scrollbar so that it will fit all screen resolutions and I was wondering how I could do this by somehow customizing the JavaScript files created by Nathan Faubion or if I could do this using other JavaScript variables (var widthPercentage) to change the pixels to percentages?One of the pages on the website I'm using the JavaScript on
