JQuery :: Making A Simple Calculator

Sep 19, 2010

I'm getting started at javascript and jQuery, I want to make a calculator for my services, for example, checking a box will add value to a total.For example theres a textbox that asks how much gallons of paint will be used, the value of each gallon is 30 dollars, so the user can write for example 2 on the input and a div will output 60. I think that would be made with .change(), but in the demo of the documentations appears a selection list, and I can't figure out how to make an input work like that.

Getting Simple Instant Price Quote Calculator?

Jan 19, 2011

I am trying to come up with an instant price quote calculator in javascript.it would be a simple one with only three fields:

"label" -Number of Shirts
"label" -Number of Colors on Front
"label" -Number of Colors on Back
"button" calculate total
"results" total: $xx per bagxx

total price would decrease based on the number of shirts (more volume) / increase based on the number of colors both front and back.

something i found online that is 100% what i want:[URL]i am not too familiar with javascript. ok tinkering with jquery but that's it.i am obviously not asking anyone to work for free but if someone could point me to a semblance of a solution, some code, something online that i could modify etc. i would love to learn javascript in the process and ideally come up with a working version of the calculator.

i tried to work with the .js from that website but it calls in some qq2.php page. so i haven't been able to replicate the solution. plus, i would assume that their price structure would be different than mine.

Changing Calculation In Simple Interest Calculator

Aug 10, 2010

The exercise problem is to "MODIFY the code in the "calculate_click" event so interest is added to future value just once each year for the number of years that they were entered by the user". The calculation as you see it below assumes an amount is invested MONTHLY (not just once), and the interest is calculated accordingly. This is what I think the problem is trying to calculate: using a $100 one time investment at 10% interest (compounded once annually) for one year = $110 as the future value. For two years, the future value should equal $121 (110 + (110*.10)). Okay, if my math is wrong, let me know. This is what I'm trying to get it to match to.

I have been able to modify the calculate_click function to compound the interest annually (it does it monthly now). Cool. I cannot get it to stop adding $100 annually. See my math above? I think that's the answer. My manipulation of the code yields $110 for the first year, $231 for the second year, etc. The $231 is incorrect cuz it adds an extra $100. See, this is a simple interest calculator I can't figure out! The original code is below that calculates the investment as a monthly investment as opposed to one-time. To avoid confusion, I did not include any of my modifications. But yeah. I know that the major culprit is how the "for" loop is being executed. I've highlighted where I think the code needs to be changed, but I haven't changed it here. Note the first function is a shortcut to execute getElementbyID.

The Code:
var $ = function (id) {
return document.getElementById(id);
} var calculate_click = function () {
var investment = parseFloat( $("investment").value );
var annualRate = parseFloat( $("rate").value );
var years = parseInt( $("years").value );
$("futureValue").value = ""; .....

Dynamic Pull Down Menu Calculator

Sep 9, 2010

I have a client who requires a dynamic pull down menu (chained Select Menu) and also requires that it does a basic price estimation based on the selected options from the menus. I have been toying around with Xin Yang Chained Select Menu(Sample A1) as well as a randomly found javascript calculator(sample A2) I found through google search. When trying to combine the two the calculator becomes broken.

Sample A1
Code:
Sample A2
<html>
<head>
<title>Calculate Amount</title>
<script language="JavaScript">
function calcAmount(){
var oprice = parseFloat(document.getElementById("oprice").value );
var sprices = document.getElementById("sprice");
var sprice = parseFloat(sprices[sprices.selectedIndex].value);
var qties = document.getElementById("qty");
var qty = parseInt(qties[qties.selectedIndex].value);
var tot = document.getElementById("tot");
tot.value = (oprice + sprice) * qty;
}
</script>
</head>
<body>
<h3>Total Amount = (OpenPrice + SetPrice) * Quantity</h3>
<table border="0" cellpadding="2" cellspacing="2">
<tr>
<td>Open Price:</td>
<td><input style="width:100;text-align:right" type="text" id="oprice" value="0">$</td>
</tr><tr>
<td>Set Price:</td>
<td><select style="width:100" id="sprice">
<option value="100">100 </option>
<option value="200">200</option>
<option value="300">300</option>
<option value="400">400</option>
</select>$
</td></tr><tr>
<td>Quantity:</td>
<td><select style="width:100" id="qty">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="100">100</option>
</select>
</td></tr><tr>
<td colspan="2"><hr></td>
</tr><tr>
<td><input type="button" value="Total Amount" onclick="calcAmount()"></td>
<td><input style="width:100;text-align:right" type="text" value="0" id="tot">$</td>
</tr>
</table>
</body>

JQuery :: How To Create Simple Popup Box DIV

Aug 6, 2011

This is my first post. This is about how to create a very simple popup box using JQuery. No third-party plugins or downloads needed. So here goes: We'll create an html file, in my case I named it index.html...
<html><head>
<title> Popup Box DIV </title>
</head><body>
<div id="popup_box"> 
<h1>This IS A Cool PopUp</h1>
<a id="popupBoxClose">Close</a>
</div><div id="container"> 
<h1>sample</h1>
</div></body></html>

Then, for our css style, we have following:
Noticed the display:none on the popup_box's syle? That is important.
<style type="text/css">
/* popup_box DIV-Styles*/
#popup_box {
display:none; /* Hide the DIV */ .....

Can I Do A Simple Update In An Excel Through An Html Page Without Using Any Dynamic Web Pages?

Sep 22, 2006

All I need to do is; on the click of a button, import the numerical
data in an html form (only one field) to a cell in a spreadsheet. Both
spreadsheet and the html file reside on the same server but there are
no dynamic capabilities. All I can use is html pages + javascript (or
anything else which do not require any special programs to be installed
on the server). Is this at all possible?

JQuery :: Simple Hide And Show - Dynamic Input Fields

Jul 29, 2009

For example I have this sort code:
for ($i=0;$i<$db;$i++) {
$t1="toggleh$i";
echo "<div class='c'>Test<input name='$t1' type='image' id='$t1' src='test.png'/></div> <br>";
}
I try to make clear the screen for users, so I use hide & show to hide some row on screen what users actually don't need...

The JS part of code is something like this:
$('#toggleh0').click( function() {
$('div.showhide').toggle(400);
});
$('#toggleh1').click( function() {
$('div.showhide').toggle(400);
});
$('#toggleh3').click( function() {
$('div.showhide').toggle(400);
});
.
.
.
I dont know how can do this dynamic. So if "$i=6;" then I need toggle 0-6 function...

JQuery :: Simple Dynamic Variable - Select Multiple Inputs

Sep 15, 2011

Basically, i have a CSS/jQuery keyboard from NETTUTS; however my problem is trying to select multiple inputs. Everything works as it should, however i want to select the input, store it in hidden field (which input is current), then when i start to type, it can enter the characters into that input field (that is selected). Currently, it just allows me to enter inputs into a single textarea. I want to onfocus, set as "Focusedfield", and when i type it goes into that field.

Here is my JS code to select/store the "focusedField". Triggered by onFocus. to make the textArea i select, be the one i type into.

Code:

Here is the jQuery

The issue is with this first $write variable. I cannot for the life of me, get it to detect the dynamic variable. When i hardcode the inputs name, it works, but when i try something dynamic - it doesn't. Line 2 of that function is where my issue is (i believe).

Code:

I've tried to replace

Code:

With

Code:

And

Code:

As well as plain old JS var "current_form".

I think its just 1 or 2 lines where this issue is.
