I've done some different things to try to add the drop down to the function but nothing would work that I've tried so far. I have it setup so when a box is unchecked, that option is taken off the price, the drop down should do the same to switch between the options price. Thanks for the help! Code: <script language="javascript">
totalOptions = 0;
function calculateTotalOptions(thisCheckbox){
if (thisCheckbox.checked)
{
totalOptions += parseFloat(thisCheckbox.value);
} else {
totalOptions -= parseFloat(thisCheckbox.value);
}
document.getElementById("totalOptions").value = "$" + totalOptions + ".00";
}

Hi all, I'm very new to Javascript and wonder if someone can help me. I'm creating an online enrolment form for my company, who are a training company. Users enrolling on the course must make three choices - The level of course, the size of course and whether they wish to attend a workshop or study by distance learning. The combination of these three factors will determine the price. I'd like to have the price automatically calculated using javascript and displayed on the form before they submit. Can anyone give me an idea of how to do this? There are three drop down boxes for users to select their course. They a - Level of Qualification: Level 3 Level 4 Level 5 Level 6 Scale of Qualification: Award Certificate Diploma Preferred Delivery Method Workshop Distance Learning Each possible combination of these will affect the price. So for instance, if the user were to select 'Level 4', 'Certificate' and 'Workshop' the price would be calculated based on these three options. How can I calculate the ultimate price and then display it on the page (I was thinking of using innerHTML in a 'span' element to display the final value, but if anyone has any better ideas I'd be glad to hear them) The HTML code for the drop down boxes is below: Code: <form action="enrolment.php" method="post"> <select name="level" class="input" id="level"> <option value="chooselevel"></option> <option value="Level 3">Level 3</option> <option value="Level 4">Level 4</option> <option value="Level 5">Level 5</option> <option value="Level 6">Level 6</option> </select> <select name="size" class="input" id="size"> <option value="choosesize"></option> <option value="Award">Award</option> <option value="Certificate">Certificate</option> <option value="Diploma">Diploma</option> </select> <select name="delivery" class="input" id="deliv"> <option value="deliverymethod"></option> <option value="Workshop">Workshop</option> <option value="Distance Learning">Distance Learning</option> </select> </form> Thanks all, hope someone here can help! Regards Chris *EDIT: I should mention that the form is also inside a table - Not sure if that will make a difference. hi, I've got a problem and i really need help. this is my code <script> var y= new Date(); y.getFullYear() + '<br />'; alert(y); var year = new Date(); year.setFullYear(prompt('Enter the year','1990'),prompt('Enter the month','1'), prompt('Enter the day','1')); alert(year); var yy = y-year; alert(yy); </script> i want when a user write his/her birthday JS calculate the age. that's all hi, i need a help for experts out there. i've a set of questionnaire with 10 questions.answer for each question to choose from is 0-6 using radio button.for all the questions answered i need to calculate overall percentage based on the scores. i've done the html coding but having problem with javascript..is there any websites i can refer to write a coding or anyone can give example how to do it. pls help.. I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live? So if the current value is 5 and I change it to 6, it will automatically recalculate the new value. You can see what I'm working on he http://sheetmusichaven.com/admin/mys...calculator.php Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date. anyone would you help me I have some problem to calculate PHP Code: <table width="415" cellspacing="1" cellpadding="1"> <tr> <th width="151" scope="col">Price</th> <th width="189" scope="col">qty</th> <th width="63" scope="col">total</th> </tr> <tr> <td><label> <input name="price" type="text" id="price" value="2000"> </label></td> <td><label> <input name="qty" type="text" id="qty" value="2"> </label></td> <td><label> <input name="total" type="text" id="total" value="4000"> </label></td> </tr> <tr> <td><input name="price" type="text" id="price" value="2000"></td> <td><input name="qty" type="text" id="qty" value="4"></td> <td><input name="total" type="text" id="total" value="8000"></td> </tr> <tr> <td> </td> <td>Total</td> <td><label> <input name="gtotal" type="text" id="gtotal" value="12000"> </label></td> </tr> </table> How to calucate it from price * qty = Total and gtotal=sum of total, in the first rows. Ican do it if there is one row, but i dont know how to calculate samae name of text field like in 2nd or more rows I want to do a calculation between selectbox values. The problem with my code is that the first part of the calculation only gives me 0, which Motherboard value*quantity. the second part works fine which Chassis*quantity. My formulas is motherbord*Quanity+chassis*quantity. Code:
function calculate() {
var parsedMotherboard = parseFloat(document.calcform.Motherboard.value || 0);
var parsedQuantity = parseFloat(document.calcform.Quantity.value || 0); var parsedChassis = parseFloat(document.calcform.Chassis.value || 0);

I wonder is there any javascript to calculate IP length For example I have Start ADDR: VLAN_ADDR which is: 10.52.28.0 Stop ADDR: VLAN_LAST which is 10.52.29.254 As I know:result is 512 or another example: Start ADDR: VLAN_ADDR which is: 10.52.64.11 Stop ADDR: VLAN_LAST which is 10.52.64.15 As I know:result is 5 How to count it in javascript code ? Results are "numbers" Best regards Leos. Hi there, I'm new here in this forum and I've registered to ask a question about JavaScript or Jquery. I don't know which to use. I have my code php like that: <?php //Get the data from system and return in EU format function ShowDate() { $Date = date("d"."/"."m"."/"."Y"); return $Date; } //Get the time from system function ShowTime() { $Time = date("H".":"."i"); return $Time; } ?> Now I have two input box <html> <head> </head> <body> Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10"> <br> Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5"> <br> London: Friday May 21 2010 05:12:00 <br> New York: Friday May 21 2010 00:12:00<br> Hong Kong: Friday May 21 2010 12:12:00<br> Tokyo: Friday May 21 2010 13:12:00<br> </body> </html> So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code. Thank you for your help. Andrei Andrade hi, can someone help me create an auto pro rata calculator where there are four [4] boxes. first box should be where we could enter the customer's plan [29,39,40 etc.] and it should be divided with what ever i will enter on the second box w/c will be for the number of days in a month [28,29,30,31]. the 3rd box should be where i can enter the number of days the cust. was able to use the service and it needs to be multiplied from box 2. 4th box should be a read only box where the pro rata will be displayed. so: [box 1] divided "/" by [box 2] multiplied "*" by [box 3] equals "=" to box four thanks!!! Hi.I have found this nice code through forum.Now I want to modify it a little bit.But dont know how to It calculates amount column value by multiplying quantity to amount.i.e. amount=qty*rate and gross total is sum of all the array elements in amount.Here I want to add two more columns viz vat% and vat amount.Simply it will be amount*vat% / 100.Can anyone please tell me how I can do that?Other thing is, is it possible to separate the 5% vat and 12.5% vat values and display the total of them in respective column?

I am trying to calculate age based on the date of birth input into a text field. the date field should allow users to enter a one or two digit month, one or two digit date and a two or four digit year. Users should be able to enter any of the following date formats: 11-2-10, 1-25-2010, or 01/25/2010. On some days it works and others it wont, like 11-1-91 returns that the user is under 18. Code: function checkAge(){
var stDate = document.getElementById("birth").value;
var dayPartToDate = parseInt(stDate.substring(0,2),10);
var monPartToDate = parseInt(stDate.substring(3,5),10);
var yearPartToDate = parseInt(stDate.substring(6,10),10);
var dtTo = new Date(yearPartToDate, monPartToDate-1, dayPartToDate);
var mydate = new Date();
mydate.setDate(mydate.getDate());
var bday = dtTo - mydate
if (bday < 18){
window.alert("You must be 18 to rent equipment.");
document.getElementById("birth").value = "";
}
}
Can anyone help me with the following Javascript. I am going crazy trying to figure this out because it should be easy. Basically 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? Code: function displaymember()
{
var m = 1;
var f = 1;
for(i=0;i<x.length;i++)
{
sex=(x[i].getElementsByTagName("sex")[0].childNodes[0].nodeValue);
if (sex=="Male")
{
m++;
}
else
{
f++;
}
percent=f/x.length * 100
document.getElementById("fixed").innerHTML=percent;
}
}
hi, I have three variables - string openTime format hh:mm - eg "08:30" - string closeTime format hh:mm eg "17:30" - float lunchHours eg 1.5 Are there any js functions I can use to calculate how many hours the shop is open ? thanks Please can u help? how would i get the total work hours between two times (8:30 to 5:30) from a web form. I tried just minusing one from the orther but it came back with "Nan" I am working on a form that has 15 rows for order entry. These rows are called: qty | part | desc | cost | amount I have the following ASP code that generates the rows: Code: <% For i = 1 To 15 %> <TR align=center><td><input type="text" NAME="qty<%Response.Write i%>" onChange='DoMath()'></td> <TD><INPUT TYPE="text" NAME="part<% Response.Write i %>"></TD> <TD><INPUT TYPE="text" NAME="desc<%Response.Write i %>"></TD> <TD><INPUT TYPE="text" NAME="cost<%Response.Write i%>" onChange="DoMath()"></TD> <TD><INPUT TYPE="text" NAME="amount<%Response.Write i%>" readonly></TD></TR> <% Next %> This gives me the following fields in the form: qty1 | part1 | desc1 | cost1 | amount1 qty2 | part2 | desc2 | cost2 | amount2 etc. My Javascript (DoMath) to calculate the row totals looks like this for now: Code: <script type='text/javascript'>
function DoMath(){
var Units = document.PlaceOrder.qty1.value;
var Rate = document.PlaceOrder.cost1.value;
var Total = Units * Rate;
document.PlaceOrder.amount1.value = Total.toFixed(2);
document.PlaceOrder.grandtotal.value = Total.toFixed(2);
}
</script>
This works fine for the first row, but I need it to scale for the rest of the rows, and also allow for future addition/expansion. Unfortunately, I am Javascript-tarded and can't figure it out, despite numerous examples online... I also need to find a way to recalculate the "grandtotal" box on the form based on whether or not the checkbox called "taxChecked" is checked. If the user checks it, I need it to recalculate the "grandtotal" field with a tax rate, and if they un-check it, it should recalcuate "grandtotal" WITHOUT the tax rate. Any suggestions or pointers are greatly appreciated! I am trying to figure out how to calculate the date 30 days ago. I also will need to be able to change the interval. Anyone have a piece of code that does this? Hi there I have tried to work on this code for the last 2 weeks, can not figure out what is wrong with my code, please have a look for me, it will greatly appreciated from me; here my details; I work on <script type="text/javascript" language="javascript"> from dreamweaver to set my code to calculate, different Fiji tour (4 options, choose 1 in options) Payment (4 options, choose 1 in options) The cost of tour - discount base on tour cost. (discount has 4 different calculate) Need to be alert if they not choose 1 in each type. Second cost if they choose to fly out , will cost plus $400 on top the above cost. This is an optional, so they don;t need to buy if they want. I have attached my code, please have a look, Thank you very much |
