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:

Calculating 2+ Form Field Inputs On The Fly

Mar 6, 2007

I'm working on a financial form that is filled out and then a pdf is outputted (via php).

I'm an xhtml/css and php guy but new to javascript - I'm sure there's got to be a way to do the following with js...

I've got a section for "project costs" with 4 fields (numeric is expected). I'd like to add a 5th field "Total Project Cost" that adds all the inputs of the first 4 fields on the fly as they are typed (or at least, after focus changes).

Also I'd like to have a field which defaults to "10" and a drop down with 3 items that will either add 0, 5 or 10 to the field which defaults to 10.

Calculating / Multiplying Form Fields (on Exit)?

Jul 16, 2009

This is probably very basic, but I don't think I'm searching the right terms to find what I need, I'm looking for an example code of how to do this.I have 3 columns (form fields below)

PRICE | ITEMS | Total

I want a user to be able to enter in a price and the amount of items so that when they leave one of those two fields, it will autocalculate and populate the "total" field. I also want the option for them to be able to fill out the total field alone, without having to enter "price" or "items". So basically 'total' has to be filled out either way, because I will then be doing calculations with that data.

Calculating Form - Calculate The Square Footage And Cost Of A Vinyl Banner?

Jul 24, 2010

I'm trying to create a four-box form in which the user enters information into the first two boxes,and the program fills the second two boxes in.Basically,I need a form to calculate the square footage and cost of a vinyl banner.In the first text box the user would enter the banner's height.In the second box the user would enter the banner's width.

The third box would multiply the height by the width and display the total square footage of the banner.So far, I have this part down. The following is what I need help with: the fourth box.The fourth box needs to display the cost of the banner. I have a complicated pricing structure. For example:

If the total square feet for the banner is under 12 square feet, the cost is \$60.00. If the square feet for the banner is between 13 and 25 square feet. The cost is \$4.80/square foot and ect...I believe this would be done using some variation of an IF statement but I can't get it to work.Using this example, what would I add to the form to get this work? The following is the form I have so far which just consists of the calculation of the square feet which is all I've been able to get working.

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%

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.

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?

What Is Percentage Of Browsers With Disabled JavaScript ?

Dec 16, 2006

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.

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;
