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 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);
var parsedQuantity1 = parseFloat(document.calcform.Quantity1.value ||0);
document.calcform.total.value = (parsedMotherboard * parsedQuantity + parsedChassis * parsedQuantity1); }

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.

#parent {overflow:auto; height:100px; }

Mike I am having troubles with calculating costs on a form. When I press the cost button, it doesn't generate the calculations. Code: var fday = document.getElementById("reg_start_date").value;
var lday = document.getElementById("reg_end_date").value;
if (fday == "2011-09-05" && lday == "2011-09-06")
{
cost = cost * 2;
}
else if (fday == "2011-09-06" && lday == "2011-09-07")
{
cost = cost * 2;
}
else if (fday == "2011-09-05" && lday == "2011-09-07")
{
cost = cost * 3;
}
I have a form where I have to calculate a future date (end date) from two fields. First the start date and then the number of months. So if the start date is 1/1/2011 and the months given is 12 then the end date should return as 12/31/2011. I can't figure out why it's not returnign a value. Here's what I have: Code: function AddDays() {
DaysToAdd=document.getElementById("DaysToAdd").value;
startdate=document.getelementbyid("startdate").value;
var newdate=new Date();
var newtimems=startdate+(DaysToAdd*730*60*60*1000);
newdate.setTime(newtimems);
document.getElementById("display").value=newdate.toLocaleString();
}

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 = "";
}
}

For example "You got - 5 out of 5" "Time Taken - 3 minutes" "Date - 24-06-2011" Thank you. 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! |
