JavaScript - Help With Calculating Shopping Total With A Quantity Textbox
I've been given this ridiculous assignment where I have to create a shopping web page. I really need help finding the javascript codes that will allow the user to update their total as they enter the quantities of the different products in the assigned text boxes.
I don't even know where to start because we were never taught how to do this in class! Similar TutorialsFolks, I am trying to calculate the total of fields on a web form. I have multiple rows of 10 fields with a total for each. Each row comes from a different record in a database. I am only showing 2 fields of the 10 for simplicity. The name and id of each field looks like "Q300_1" onchange="update(Q300)" "Q300_2" onchange="update(Q300)" "Q300_t" "Q301_1" onchange="update(Q301)" "Q301_2" onchange="update(Q301)" "Q301_t" My current attempt at the script looks like: [CODE] <script type="text/javascript"> function update(item) { var itemt=item + "_t"; var item1=item + "_1"; var item2=item + "_2"; document.myform[itemt].value = (document.myform[item1].value -0) + (document.myform[item2].value -0); } </script> [CODE] It does not work and I get Error: Q301 is not defined in the Firefox error console. Hi all, I am trying to have a form calculate total using this script, works OK until the total reaches 99 from there on it only returns 2 figures. Also it won't work if I complete the dollar value (i.e add .00) Anyone tell me where I am going wrong? Code: <script type="text/javascript">
function startCalc(){
interval = setInterval("calc()",1);
}
function calc(){
q1 = document.apply.appfee.value = 11;
q2 = document.apply.memfee.value = 20;
q3 = document.apply.levy.value;
q4 = document.apply.donation.value;
document.apply.total.value = (q1*1) + (q2*1) + (q3*1) + (q4*1)
}
function stopCalc(){
clearInterval(interval);
}
</script>
This is the form: Code: <form name="apply" action="" method="post" onsubmit="return validate(apply)"> <table style="width:680px;"> <tr> <td style="text-align:right; white-space:nowrap; width:300px;">Application Fee:</td> <td style="text-align:left; white-space:nowrap; width:441px">$<input type="text" readonly value="" name="appfee" style="width:17px; border:0; font:11px verdana; color:#006;margin-bottom:5px;"></td> </tr> <tr> <td style="text-align:right; white-space:nowrap; width:300px;">Annual Memebership Fee:</td> <td style="text-align:left; white-space:nowrap;">$<input type="text" readonly value="" name="memfee" style="width:17px; border:0; font:11px verdana; color:#006;margin-bottom:5px;"></td> </tr> <tr> <td style="text-align:right; white-space:nowrap; width:300px;">* Optional Annual Levy:</td> <td style="text-align:left;"> $<select name="levy" onFocus="startCalc();" onBlur="stopCalc();"> <option selected>0</option> <option value="22">22</option> <option value="44">44</option> <option value="66">66</option> <option value="88">88</option> <option value="110.00">110</option> </select> </td> </tr> <tr> <td style="text-align:right; white-space:nowrap; width:300px;">* Optional Donation:</td> <td>$<input type="text" name="donation" value="" onFocus="startCalc();" onBlur="stopCalc();" style="font:11px verdana; color:#006;margin-bottom:5px; width:80px;"></td> </tr> <tr> <td style="text-align:right; white-space:nowrap; width:300px;"><b>TOTAL:</b></td> <td white-space:nowrap;><b>$<input type="text" name="total" style="width:17px; border:0; font:bold 11px verdana; color:#006;margin-bottom:6px;"></b></td> </tr> </table> </form> I have everything working up to this point but when I try and put the math equation into my script section, I get multiple error and cannot figure out how to get the function to return the actual total rental cost. If you could please look at what I have, your opinions would be greatly appreciated. Thank you. Below is the code with the math function at the end of the script section in the heading which I seem to be receiving error on. Any help is greatly appreciated. Thanks. Code: <!DOCTYPE html PUBLIC

For various reasons, I need the value of my drop down box options to contain size information rather than price. However I would like to be able to calculate a price for the items based on what size the user selects as well as the quantity. Below is the code I came up with (which doesn't work obviously) What can I do to get this to work for me? Thanks in advance for any help! Code: <head>
<script type="text/javascript">
<!--
function calc(A,B,SUM) {
var price = document.getElementById(A).extrainfo;
var quantity = document.getElementById(B).value;
document.getElementById(SUM).value = price * quantity;
}
//-->
</script>

Good day! I am new in javascript function. I have Javascript code for auto calculate here is the code: Code: <script type="text/javascript" language="javascript">
function autocalearn(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, TotEarn = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements
{
field = arguments[a];
val = parseFloat(field.value); //get value
if (!isNaN(val)) //number?
{
TotEarn += val; //accumulate
}
}
var tot=Number(TotEarn) + Number(document.getElementById('Amount').value);
oForm.TotEarn.value = tot.toFixed(2);
//oForm.TotEarn.value = TotEarn.toFixed(2); //out
}
</script>
<!--Total Deduction AutoCompute-->
<script type="text/javascript" language="javascript">
function autocalded(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, TotalDed = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements

val = parseFloat(field.value); //get value

}
}
//oForm.TotalDed.value = TotalDed.toFixed(2); //out
var totded=Number(TotalDed) + Number(document.getElementById('Deductions').value);
oForm.TotalDed.value = totded.toFixed(2);
}
</script>
and now my problem is...I have a textbox for the overall total, and i want it automatic subtract the total earn and total deduction.. I will attach my codes for further understanding. Thank you in advance Hi.. I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php
error_reporting(0);
date_default_timezone_set("Asia/Singapore"); //set the time zone
$con = mysql_connect('localhost', 'root','');
if (!$con) {
echo 'failed';
die();
}
mysql_select_db("mes", $con);
?>
<html>
<head>
<script type="text/javascript">
function ini()
{
// Retrieve the code
var code =document.getElementById ("code_read_box1").value;
var code =document.getElementById ("code_read_box2").value;

var code =document.getElementById ("code_read_box4").value;
var code =document.getElementById ("code_read_box5").value;

subtotal.innerHTML = price;
grand_total.innerHTML = (shipping + price).toFixed(2);
update_tax();

Thanks Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post">
<table>

<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />

Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! I have an online shopping cart and some of the products are sold in boxes of 6. So I am trying to write some code that will alert the customer if they have entered a quantity that isn't some multiple of six. I've tried using the modulus operator as well as dividing by 6 and then checking to see if the result is a whole number but inevitably the alert box pops up no matter what I enter. This is what I'm trying to use now: Code: <head>
<script type="text/javascript">
function calculate(qtyordered)
{
if (qtyordered%6!=0)
{
alert("Blades are sold in boxes of 6." + '\n' + "Please correct your order quantity.");
return false;
}
else
{
return true;
}
}
</script>
</head>
<body>
<form action="http://ww4.aitsafe.com/cf/add.cfm" onsubmit="return calculate(qtyordered)" method="post">
<input name="qtyordered" type="text" value="0" size="4" maxlength="4">
</body>
What am I doing wrong? Is there a better way to check if the entered quantity is a multiple of 6? I am trying to combine shipping across different items in a javascript shopping cart. I can comine shipping based on how many items are in the cart, and characteristics of the item being added. But not both. I need the script to combine shipping based on how many items are in the cart, as well as the item name of the item being added to the cart. I assume I need to check the cart quantity in 1 function, then have it call 1 of 2 other functions based on how many items are in the cart. The 2nd function would charge the shipping based on the item name. I don't know if the code is wrong, and where I should put the 2 additional functions I am adding. It isn't working though. I am adding 2 ways I have tried below. Code: me.shipping = function(){
switch(me.quantity){
case '0':
return 0;
break;
case '1':
return oneItemInCart();
break;
default: otherNumber;
return moreThanOneItemInCart();
break;
}
function oneItemInCart();
{
if(item.name)
{
if(item.name.match = "Cricut Cartridge")
return 4.39
else if(item.name.match = "Glitter")
return 5.00
else
return quantity*0.00;
}
}
function moreThanOneItemInCart();
{
if(item.name)
{
if(item.name.match = "Cricut Cartridge")
return item.quantity*3.00-3.00+4.39
if(item.name.match = "Glitter")
return item.quantity*4.00-4.00+5.00
else
return quantity*0.00;
}
}
Code: me.shipping = function(){
if( parseInt(me.quantity,10)===0 )
return 0;
else if( parseInt(me.quantity,10)===1)
return oneItemInCart();
else if( parseInt(me.quantity,10) > 1)
return moreThanOneItemInCart();
else
return quantity*0.00;
function oneItemInCart();
{
if(item.name)
{
if(item.name.match = "Cricut Cartridge")
return 4.39
else if(item.name.match = "Glitter")
return 5.00
else
return quantity*0.00;
}
}
function moreThanOneItemInCart();
{
if(item.name)
{
if(item.name.match = "Cricut Cartridge")
return item.quantity*3.00-3.00+4.39
if(item.name.match = "Glitter")
return item.quantity*4.00-4.00+5.00
else
return quantity*0.00;
}
}
Here is the original document - the part I edited is the me.shipping part http://simplecartjs.com/ I now have the calculation, topic can be closed! thanks Hello everyone. Below is code I have developed for a simple spreadsheet. The issue I am having is that when I total a row or column using "=sum(a1:a5)" and then I try and total another row and add the sum of the two totals together I am not getting a valid response back. All I am presented with is a "0" in the column cell. Here is the code in two files and have also included an attachment of the whole project: tablepage.js Code: // JavaScript Document

Hi, I am trying to write a script that will take a date of birth and another date and, if the person was over 75 years old on the createdDate, return "true" (otherwise return "false"). Unfortunately my code doesn't seem to return either 'true' or 'false'! Any help would be grately appreciated. The code is: Code:
var dateofBirth="30/10/1982";
var createdDate="01/12/2010";
var sd = dateofBirth.split('/');
var dob = new Date(sd[2],sd[1],sd[0]);
sd = createdDate.split('/');
var submit = new Date(sd[2],sd[1],sd[0]);
var age=submit-dob;
var ageYears=Math.floor((((age/3600000)/24)+1)/365.25);
if(ageYears>75) document.write("true") else document.write("false") ;
Hi, There are two text boxes in a HTML form. The first text box takes the time when the user starts to work on a project. The second box takes the time when the user stops working on that project. Now, I would like to calculate the total time worked on that project for that user. That is (stop time - start time). I tried few things without success. Any help will be appreciated. to be honest I have no idea where to start, i have a table, with 2 numeric values at the minute, if the checkbox is selected I want the total price to be shown? Any help to get me started would be great! this is the form I have with the numeric values Code: <form id="calculation" action="#" method="post"> 100 <input type="checkbox" name="check1" value="100" onClick='total_cost()'/> 120 <input type="checkbox" name="check2" value="200" onClick='total_cost()'/> Total cost<input type="text" name="total" id="total" readonly="readonly" /> onClick='total_cost()' is referring to the javascript function where I just don't know where to start? I'm trying to find the difference between 2 times. Time formats are 00:00:00.0 For example... var t1 = "00:07:51.0"; var t2 = "00:53:21.0"; How do I calculate the difference between those 2 times? TIA. Hey there, first time poster. I am trying to create an order with the ability to dynamically self total the sum of the selected items but also be able to add a 25% labor fee having it be at least $90. So if someone buys $300 worth of items the labor charge would be $75 but it would be automatically bumped to $90. heres the existing code: PHP Code: * Calculates the payment total with quantites * @param {Object} prices */ countTotal: function(prices){ var total = 0; $H(prices).each(function(pair){ total = parseFloat(total); var price = parseFloat(pair.value.price); if ($(pair.key).checked) { if ($(pair.value.quantityField)) { price = price * parseInt($(pair.value.quantityField).getSelected().text, 10); } total += price; } }); if (total === 0) { total = "0.00"; } if ($("payment_total")) { $("payment_total").update(parseFloat(total).toFixed(2)); } }, /** * Sets the events for dynamic total calculation * @param {Object} prices */ totalCounter: function(prices){ $H(prices).each(function(pair){ $(pair.key).observe('click', function(){ JotForm.countTotal(prices); }); if ($(pair.value.quantityField)) { $(pair.value.quantityField).observe('change', function(){ $(pair.key).checked = true; JotForm.countTotal(prices); }); } }); }, I thought this would be simple. Evidently it's not With the date below (and it being 11.45 on the 27th as I type this), the counter returns the correct number of hours/mins/seconds remaining, but shows 33 days. It seems to be adding 31 days to the count, but I can't figure out where Code: function countdown(){
var bigday = new Date(2009,10,29,14,30,0,0);
var today = new Date();
var difference = bigday - today;
var remaining = Math.floor(difference/1000); // want seconds, not milliseconds
var days = Math.floor(remaining/86400);
remaining = remaining % 86400;
var hours = Math.floor(remaining/3600);
remaining = remaining % 3600;
var minutes = Math.floor(remaining/60);
remaining = remaining % 60;
seconds = Math.floor(remaining);
var out = days + " days, " + hours + " hours, " + minutes + " minutes and " + seconds + " seconds left...";
$('#countdown').text(out);
setTimeout(countdown, 1000);
}
