How to get sum of html element's values with specific class names in the multiple divs have same class name.

HTML

<html>
<link REL="STYLESHEET" TYPE="text/css" HREF="checkoperations.css">


<script type="text/javascript" src="jquery.js"/>&lt;/script>
<script type="text/javascript" src="checkoperations.js"></script>
<body>

<input type="button" id="calculate" value="calculate"/>
<div class="testdiv">
      <input type='checkbox' name='checked2' value='check' class='ckbox'>
      <input type='text' class ='fieldsbankrecon1' readonly='readonly' value='7'/>
      <input type='text' class ='fieldsbankrecon' readonly='readonly' value='8'/>

</div>

<div class="testdiv"  >
      <input type='checkbox' name='checked' value='check' class='ckbox'>
      <input type='text' class ='fieldsbankrecon1' readonly='readonly' value='1' />
      <input type='text' class ='fieldsbankrecon2' readonly='readonly' value='2' />

</div>


<div class="testdiv"  >
      <input type='checkbox' name='checked' value='check' class='ckbox'>
      <input type='text' class ='fieldsbankrecon1' readonly='readonly' value='1' />
      <input type='text' class ='fieldsbankrecon2' readonly='readonly' value='2' />

</div>

<div class="testdiv"  >
      <input type='checkbox' name='checked' value='check' class='ckbox'>
      <input type='text' class ='fieldsbankrecon1' readonly='readonly' value='1' />
      <input type='text' class ='fieldsbankrecon2' readonly='readonly' value='2' />

</div>

<body>

</html>

jQuery code

JavaScript

var sum = 0;
$('#calculate').click(function()
    {

    $('.testdiv').each(function() {
    //var $this = $(this);
    //if ($this.is(':checked')) {
        var currentValue = parseInt($(".fieldsbankrecon1").val(),10);
        sum = sum  + currentValue;
        //}
         alert(message);

    });

Message is always 7 which is the first text box in the first div.
It's iterating four times though, but I don't know why the value is not changing.

I guess my message is not completely shown here. My HTML code has four divs with same class name that is testdiv and inside each div there are three input boxes.

I would really appreciate the help.

You would want to do something like this:

var sum = 0;        
$(".fieldsbankrecon1").each(function() 
{ 
  if(!isNaN(this.value) && this.value.length!=0) 
  {
    sum += parseFloat(this.value);            
  }         
});

Update
Add the following div to the body of your document

<div id="output">

</div>

This script will automatically recalculate the sum as the user checks and unchecks the checkboxes:

<script>
    var evaluateFields = function ()
    {

        var sum = 0;
        var n = $("input:checked").each(function ()
        {
            $(this).parent().find(".fieldsbankrecon1").each(function ()
            {
                sum += parseFloat(this.value);
            });
        });
        $("#output").text("Sum:"+sum);
    };
    evaluateFields();

    $("input[type=checkbox]").on("click", evaluateFields);

</script>

You can also add multiple fields with the appropriate class to each of your divs.
