JavaScript - Help Needed:auto Calculate Total From Rows Added & Add Serv. Charge To Get Grandtotal

Hi, please help. I've been trying to check what I did wrong in my code but still the total doesn't show. Below is my javascript function:
Code:

function CalculateTotal(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r) 
{ 
    var tota= document.getElementById('a'); 
var totb= document.getElementById('b'); 
var totc= document.getElementById('c'); 
var totd= document.getElementById('d'); 
var tote= document.getElementById('e'); 
var totf= document.getElementById('f'); 
var totg= document.getElementById('g'); 
var toth= document.getElementById('h'); 
var toti= document.getElementById('i'); 
var totj= document.getElementById('j'); 
var totk= document.getElementById('k'); 
var totl= document.getElementById('l'); 
var totm= document.getElementById('m'); 
var totn= document.getElementById('n'); 
var toto= document.getElementById('o'); 
var totp= document.getElementById('p'); 
var totq= document.getElementById('q'); 
var totr= document.getElementById('r'); 	




	var grandTotal = tota + totb +totc + totd + tote + totf + totg + toth + toti +totj + totk + totl + totm + totn + toto + totp +totq + totr; document.getElementById('Total').value = grandTotal.toFixed(2);
}

Below is my textbox where there are more than 10 textboxes for user to enter donation amount. I'd like to calculate all the donation amount entered then show total in the bottom.
Code:

Please help. I tried for how many days using the javascript calculations and still didn't work. I have a form with the same calculations and it does work but this one doesn't. Please help. Thanks a lot. Hope to hear from you soon.

Need help please asap. It might be simple but i couldn't work out the script. help!
----------------
Formfield.anzahl1 = number entered by customer
Formfield.Price1 = Ergebnisfeld1
e.g.
Anzahl1= 1
Price = 270
*if Anzahl1 = 2 then Price = 270*2

I need to do this for two form option. 2nd field would be as follows

Formfield.Anzahl2= number entered by customer
Formfield.Price2 = Ergebnisfeld2

Then Formfield.Total = Ergebnisfeld1 + Ergebnisfeld2
-------------------
How can I convert these above to javascript?

Hi,

I have a dynamic JS table and the user can add several rows then populate rows with data.
There are 4 columns in table. First row, first two columns have JQuery calendar. Third column has populated select list. Fourth column, first row has JS function to ensure that user enters integer/decimal with corresponding alert for incorrect entry.
Two things I want to do:
1. Populate added rows with JQuery calendars and integer/decimal alert.
2. Capture added rows and data from user entries so that information can be sent to database via ColdFusion programming.

The following is the js code I am using:

For the datepicker I linked to an in-house URL so this is the function -

Code:

$(function() {
		$("#startdate").datepicker();
		$("#enddate").datepicker();
		$("#RcompStart").datepicker();
		$("#RcompEnd").datepicker();
	});
</script>

The objects (inputs) for the above are

Code:

<td><input style="width: 70px" type="text" id="startdate"></td> 
<td><input style="width: 70px" type="text" id="enddate"></td>

For the numeric alert the function is

Code:

<script type="text/javascript">
function checkQuarters( fld )
{
    var val = parseFloat(fld.value);
    if ( isNaN(val) || ( val*4 != Math.floor(val*4) ) )
    {
        alert("Value must be a numeric and a multiple of 0.25");
        return false;
    }
    return true;
}
</script>

The object (input) for the above is

Code:

<td><p>
<form style="width: 5px; height: 1px;">
<input type="text" name="No. of Hours" id="No. of Hours" style="width: 70px;" onblur="checkQuarters(this);" /> </form> </td>

And to add and remove rows the function is

Code:

<script language="Javascript" type="text/javascript">
/*<![CDATA[*/
		   
  var new_rows=new Array();
  var row_count=0;

function addRow()
 {
    var tbl = document.getElementById('ReqDtTbl');

    var sel = document.createElement('select');

          cellRight.appendChild(el);
          new_rows[row_count]['cell']=el;
          row_count++;
     }
     function removeRow()
     {
          // grab element again
          var tbl = document.getElementById('ReqDtTbl');
          // grab length
          var lastRow = tbl.rows.length;
          // delete last row if there is more than one row
          if (lastRow > 2) tbl.deleteRow(lastRow - 1);
     }
	 /*]]>*/
</script>

The buttons for this function are

Code:

<input type="button" value="Add a row" onclick="addRow('ReqDtTbl',5)";/>

   <input type="button" value="Remove a row" onclick="removeRow();" />

That's it.

Thanks - John

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?
Here is the link for reference : http://kavisandeepdwivedi.com/forum.php
Please go through the code below and help me out

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 all...

i need to auto calculate 3 fields and store the result in 2 fields:

field 3 = field 1 * field 2
field 5 = (field 1 * field 2) - field 4 or field 3 - field 4

so far i'm trying to modify an existing code but i'm still can't get it working correcly

Code:

    <html>
    <head>
    <script type="text/javascript">
    function compute(inputObj, otherInputID, multiID, subID, diffID) {
    var otherObj = document.getElementById(otherInputID)
    var multiObj = document.getElementById(multiID)
	var subObj = document.getElementById(subID)
    var diffObj = document.getElementById(diffID)
     
    var v1=inputObj.value
    var v2=otherObj.value
	var v3=multiObj.value
	var v4=subObj.value
     
    var val1 = v1=="" ? 0 : parseFloat(v1) // convert string to float
    var val2 = v2=="" ? 0 : parseFloat(v2)
	var val3 = v3=="" ? 0 : parseFloat(v3)
	var val4 = v4=="" ? 0 : parseFloat(v4)
	


    multiObj.value = val1 * val2
	diffObj.value =  (val1 * val2)-val4
	
	}
	
	
	
    </script>
    </head>
     
    <body>
    Value 1: <input id="txt1" type="text" onKeyUp="compute(this, 'txt2', 'addres', 'subtract', 'mulres')">
    <br />
    Value 2: <input id="txt2" type="text" onKeyUp="compute(this, 'txt1', 'addres', 'subtract', 'mulres')">
    <br />
    Added Result: <input id="addres" type="text">
    <br />
    substract: <input id="subtract" type="text" onKeyUp="compute('txt1', 'txt2', 'addres', this, 'mulres')">
    <br />
    Multiplied Result: <input id="mulres" type="text">
    </body>
    </html>

my problem is the Multiplied Result field not automatically change the result when i enter value in subtract field. it will change if i retype the value in field 1 and 2.
Hope somebody can help me.

Thank in advance

Hi..

I have syntax for autocalculate the max lot and the output display in Total_max same with min lot and the output display in Totam_min, now I need to have convert automatically the number I was inputted in max lot textbox and it will display in max doz textbox same also with min lot convert to min doz textbox.

the conversion is:

max doz = max lot * 10
min doz = min lot * 10

here is my code:

Code:

<html>
<head>

    document.loading_kanban.action="ParameterSettings.php";
    document.loading_kanban.submit();
}
function display_Kanban(){
    document.loading_kanban.action="kanban_report.php";
    document.loading_kanban.submit();
}
</script>

<script type="text/javascript">
//Code for auto calculate Total Max//
function autocalearn(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, Total_max = 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?
{
Total_max += val; //accumulate
}
}
oForm.Total_max.value = Total_max.toFixed(2); //out
}

</script>


<script type="text/javascript">
//Code for auto calculate Total Min//  
function autocalmin(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, Total_min = 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?
{
Total_min += val; //accumulate

I attach the sample imge of my webpage.

I am trying to create a simple auto-calculate function for a webpage.

What should be happening:
The 'onchange' command should pass the 'price' of the item to the function, the function should then cycle through all the dropdowns (or checkboxes or fields) and calculate the total.

What is happening:
It is only picking up the last checkbox. It seems that the 'for' loop only remembers the last item in the array.

What am I doing wrong? How can I get the code to remember all the items?
thanks,

Code:

<script language="JavaScript" type="text/javascript">

function calculateTotal(price)
{
	var total = 0;	
	var cList = ['sel1','sel2','sel3'];	
	for (i=0;i<2;i++); 
	var select = GetE(cList[i]); total+= price * (select.options[select.selectedIndex].value); 	
	GetE("totalShow").innerHTML = total.toFixed(2);		
}

function GetE(id) {return document.getElementById(id); }
</script>

<html>
<head></head><body>
<form id="form1" name="form1" method="post" action="">

    <select name="sel1" id="sel1" onchange="calculateTotal(100)">
        <option value="0">0</option>
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
    </select><br><br>
     <select name="sel2" id="sel2" onchange="calculateTotal(200)">
             <option value="0">0</option>
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
    </select><br><br>
     <select name="sel3" id="sel3" onchange="calculateTotal(300)">
        <option value="0">0</option>
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
    </select><br><br>
  </form>
<br>total <span id="totalShow">0.00</span>

Looking for an example of how to take the value typed in one textbox to be calculated and update the value of a second texbox on the fly.

The calculation is,

(2.9% X first textbox value) + $0.30 = second textbox value

Hello,

I don't know if this can be done in Javascript, or requires any other language but i was wondering if this would be possible.

I would like to embed this Javascript code in to a PHP file and then for it to run automatically upon the PHP file loading:

Code:

<td class="smallDesc"> <a name="fb_share" type="button_count" href="http://www.facebook.com/sharer.php">Share</a><script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script> </td>

The Javascirpt is the Facebook Share button that basically allows users that have Facebook to share the page there currently on in their Facebook status by pressing the button, but if there not logged in it shows the login page, not a problem just continue the script.

The current button i which is what i want to load automatically in the PHP file is located here, to test the functionalilty just click "Share" button in blue..

http://watch-movies-online.anyfilman...-Movie-17.html

To summarise, i would like the above Javascript code to execute automatically upon pageload of this PHP file.. http://www.watch-movies-online.anyfi...p://google.com.

If that could be done, and if this also is possible.. i would like for the "Share" button on the external page that is loaded from the Javascript code above to be clicked automatically so in effect when ever someone visits the PHP page after clicking "Click Here to Watch/Stream 2012 Online For Free" on this page it will automatically load the Facebook Share box, and automatically click the "Share" Button and then close the page if possible, but not required.

Please feel free to ask any questions, i'll be happy to answer.

Thanks in advance.

Best Regards,
Jonathan.

Hey all!

I have a script below that is very basic. when a user submits a blank form this popups. although i want to set the value of the input field to 'you@domain.com'. how would i add this value to this javascript so that even though there is 'you@domain.com' in the box, an error will still popup??

Thanks,

Code:

function validate(form_id,email) {
   var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
   var address = document.forms[form_id].elements[email].value;
   if(reg.test(address) == false) {
      alert('Please enter a valid email address');
      return false;
   }
}
