Calculating Shopping Total With A Quantity Textbox?
Sep 27, 2011
I've been given this ridiculous assignment where I have to create a shopping web page.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!
Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.
I'm creating a website where users won't need to register but can vote for one thing once per day. What I'm having trouble with however is how to go about calculating each vote, and displaying the total votes next to each item. Every a time user votes, I want the total to be updated and shown in the red areas next to the choices that can be voted for.
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.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.

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)
<script type="text/javascript"> function startCalc(){ interval = setInterval("calc()",1);[code]....
I found this useful script for setting equal column height for divs. But is doesn't account for the padding inside the divs. How to make it calculate the total height including the padding from the heighest column?
how to add up a series of text boxes which contain numbers that a user will input and have the total of those text boxes show up in a quantity text box on the next page.
Not sure if i should use javascript or php, but i don't know how to do it either
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?
I am trying to add a spin control to my quantity field before i add the ordered quantity to a shop cart array. The way its set up at the moment if you click the deincrement arrow it actually goes into negative numbers. (no good coz people cant order a negative number eh#$@#$@) This the
<head> Code <!---sPIN BUTTONS TO UP QUANTITY---> <script type="text/javascript"> function changeVal(n) { document.forms[0].quantity.value =parseInt(document.forms[0].quantity.value) + n; } </script> [Code]
<script language="javascript"> function getTotal(i){ var tot = 0; var total=0; var totalaccurate=0; var tbys = document.getElementById('blw'+i).value; var total=document.frmtot.totblw.value; if(tbys ==""){ tbys = 0; }if(total ==""){ total = 0; }var tot1 = parseInt(tbys) + parseInt(total); document.frmtot.totblw.value = tot1; } </script>
The above script is ok if entering the value first time. But when the user changes the value in any text box, it seems to add incorrectly. It adds what was already in the textboxes, then adds it again. How to display the correct value every time the user changes a value in one of the text boxes.
I'm trying to calculate the total on an php page. I'm able to get the checkbox portion to work properly but I'm having trouble with the textbox "txtshipping". The default is 7.95 but if changes I need to change the total.
How can I make the totalbox the default of the textbox of "txtshipping"? Code:
I am trying to add up some fields, it works but to get the total you have to click on the total box. Is there any way of getting it to total automatically i.e. when the user enter a quanity it will show the total straight away without having to click the total box.
Below is my code <html><head><title>Online Order</title></head> <body bgcolor=white onLoad="document.arith.total.value=eval(0);
I used the sum of check boxes script, altered it for radio buttons and it works... except for one little nit-picking thing.If a user changes their mind and chooses the other radio button in the set, the total does not reflect the actual total unless they click again on an already set radio button on the side they are using.Here's the JS:
Code: //Adds the sum of all radio buttons for the Home Team (Games Won) function UpdateCost() { var sum = 0;[code]......
How can I get this to reflect the actual games won if a user changes a radio button from home team to visiting team? I have a duplicate JS (UpdateCost2) and I have a matched pair of radio buttons for each game. Either you win (get 1) or lose (get 0).
I have a page that lists a bunch of golf clubs. They are ordered by catagory (drivers, woods, etc) When you click on a check box the javascript puts the price in a sub-total box. I need it to also add up the total for the page.Here's a link to the page:
http:[url]....Here is the javascript at the top:
Code: <script language=javascript> var a=<?php echo $row_recDrivers['cPrice']; ?>; //set driver value. var b=<?php echo $row_recWood['cPrice']; ?>; //set wood1 value.[code].....
The problem is when i will calculate if quantitiy/buyquantitiy is an integer. The reason is that some products can only be seld as 4 items, and if you press 3 wou should get a message that says "Sorry a quantity of 3 are not aviable because there are 4 items in package". Can transfer 2 varibales into the function? Or have anyone any suggestion how to solve this.
Need some possible technical solutions to my current project. Im in the middle of creating an 'offline' photo gallery website (on CD). Quite simple, but the challenge is how I can build an offline ordering process which
1) Allows the person browsing the cd photo gallery to select various photos, 2) Generate some sort of page/file which can then be printed then faxed, or even emailed if possible.
Does anyone have any tips on the best way to do this?
I have installed a purchased shopping cart and for the price is does most of what I need...the problem is the shopping cart doesn't empty after the order is sent. I have copied all of the various pieces of the script into an RTF if anyone would like to take a look at it. It's too long to post the whole thing here...or should I?
I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:
document.getElementById ('total').value = total
This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.
1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.
I have just joined this forum hoping for some help on a problem i am having, i have a feeling the solution is simple but im a noob at JAVA so i have no idea how to work it out.

When you select US (West Coast) as your location it doesn't update the price on the right properly. If you select it first it just won't display anything. if you select it after choosing another one and hitting continue then it doesn't change.
