JavaScript - Calculate Once New Value Is Typed In
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. Similar TutorialsI have no clue if this is in the correct forum but.... is there a way to determine whether a user clicked on a link vs typed in the url to get to a page? I'm trying to stop users from messing with GET forms (and i have to use them, POST wouldn't make sense in this case). Thanks I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers. My formulas for all 4 calculations are as follows: First: Inputted Value * 10 Second: Inputted Value * 20 Third: Inputted Value / 2 Fourth: Inputted Value * 2 Here is my code I'm working with: PHP Code: <?php session_start(); $username = $_SESSION['username']; include_once('inc/connect.php'); $credquery = mysql_query("SELECT * FROM userstats WHERE username='$username'"); $row = mysql_fetch_assoc($credquery); $credits = $row['credits']; $bannercredits = $row['bannercredits']; $textcredits = $row['textcredits']; $sitetobanner = $_POST['sitetobanner']; $sitetotext = $_POST['sitetotext']; $bannertotext = $_POST['bannertotext']; $texttobanner = $_POST['texttobanner']; if (isset($sitetobanner)){ $bannerimp = round($_POST['bannerimp']); if ($bannerimp > 1){ $s = "s"; } if ($bannerimp <= $credits){ $newcredits = $credits - $bannerimp; $newbannercredits = $bannerimp * 10; $totalbannercredits = $bannercredits + $newbannercredits; $updatebanner = mysql_query("UPDATE userstats SET credits='$newcredits', bannercredits='$totalbannercredits' WHERE username='$username'"); $credits = $row['credits']; $bannercredits = $row['bannercredits']; $textcredits = $row['textcredits']; $convertedbanner = "You converted ".$bannerimp." credit".$s." into ".$newbannercredits." banner impressions"; } else{ if ($credits>1){ $mycredits = $credits - 1;} $errorbanner = number_format($mycredits, 0, '.', ''); } } if (isset($sitetotext)){ $textimp = round($_POST['textimp']); if ($textimp > 1){ $s = "s"; } if ($textimp <= $credits){ $newcredits = $credits - $textimp; $newtextcredits = $textimp * 20; $totaltextcredits = $textcredits + $newtextcredits; $updatebanner = mysql_query("UPDATE userstats SET credits='$newcredits', textcredits='$totaltextcredits' WHERE username='$username'"); $credits = $row['credits']; $bannercredits = $row['bannercredits']; $textcredits = $row['textcredits']; $convertedtext = "You converted ".$textimp." credit".$s." into ".$newtextcredits." text ad impressions"; } else{ if ($credits>1){ $mycredits = $credits - 1;} $errortext = number_format($mycredits, 0, '.', ''); } } if (isset($texttobanner)){ $texttobannerimp = round($_POST['texttobannerimp']); if ($texttobannerimp > 1){ $s = "s"; } if ($texttobannerimp <= $textcredits){ if ($texttobannerimp>=2&&$texttobannerimp>""){ $newcredits = $textcredits - $texttobannerimp; $newbannercredits = $texttobannerimp / 2; $totalbannercredits = $bannercredits + $newbannercredits; $updatebanner = mysql_query("UPDATE userstats SET textcredits='$newcredits', bannercredits='$totalbannercredits' WHERE username='$username'"); $credits = $row['credits']; $bannercredits = $row['bannercredits']; $textcredits = $row['textcredits']; $convertedtextimp = "You converted ".$texttobannerimp." text ad impression".$s." into ".$newbannercredits." banner impressions"; } else{ $convertedtextimp = "You Hag"; } } else{ if ($textcredits>1){ $mycredits = $textcredits - 1;} $errortextimp = number_format($mycredits, 0, '.', ''); } } if (isset($bannertotext)){ $bannertotextimp = round($_POST['bannertotextimp']); if ($bannertotextimp > 1){ $s = "s"; } if ($bannertotextimp <= $bannercredits){ $newcredits = $bannercredits - $bannertotextimp; $newtextcredits = $bannertotextimp * 2; $totaltextcredits = $textcredits + $newtextcredits; $updatebanner = mysql_query("UPDATE userstats SET bannercredits='$newcredits', textcredits='$totaltextcredits' WHERE username='$username'"); $credits = $row['credits']; $bannercredits = $row['bannercredits']; $textcredits = $row['textcredits']; $convertedbannerimp = "You converted ".$bannertotextimp." banner impression".$s." into ".$newtextcredits." text impressions"; } else{ if ($bannercredits>1){ $mycredits = $bannercredits - 1;} $errorbannerimp = number_format($mycredits, 0, '.', ''); } } ?> <html> <head> <title>Convert Credits</title> <script type="text/javascript" language="javascript"> function inputLimiter(e,allow) { var AllowableCharacters = ''; if (allow == 'NumbersOnly'){AllowableCharacters='0123456789.';} var k; k=document.all?parseInt(e.keyCode): parseInt(e.which); if (k!=13 && k!=8 && k!=0){ if ((e.ctrlKey==false) && (e.altKey==false)) { return (AllowableCharacters.indexOf(String.fromCharCode(k))!=-1); } else { return true; } } else { return true; } } </script> </head> <body> <h1>Convert Credits</h1><br /> Credits: <?php echo $credits; ?><br /> Banner Impressions: <?php echo $bannercredits; ?><br /> Text Ad Impressions: <?php echo $textcredits; ?><br /> <form action="convert.php" method="POST"> <h3>Credits To Banner Impressions</h3> Convert <input type="text" name="bannerimp" id="NumbersOnly" onkeypress="return inputLimiter(event,'NumbersOnly')" value="<?php echo $errorbanner; ?>" onChange=""> credits into BLANK Banner Impressions!

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.

For example "You got - 5 out of 5" "Time Taken - 3 minutes" "Date - 24-06-2011" Thank you. 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 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? 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();
}
Any insight is appreciated. 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! 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 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 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?

Hello, I'd like to be able to calculate the difference between 2 dates in the format dd/mm/yyyy var date1 = 06/01/2012 var date2 = 10/01/2012 Then an alert box would tell me there is a difference of 4 days. Thanks a bunch Jay. |
