Question

I’m looking to sum up all text as numbers inside the class called “sent” but when I alert the below code it gives output of zero:

var sum = 0;            
var thedate = $(".date:contains('15th February 2012')");

   $(thedate).each(function() {              
    var sents = $(this).next('.sent').text();

    var sentsnumb = parseFloat(sents);

        sum += Number($(sentsnumb));

});
    alert(sum);

Here is my html:

<tr>
   <td class="date">15th February 2012</td>
   <td class="sent"> 5</td>
</tr>
<tr>
   <td class="date">15th February 2012</td>
   <td class="sent"> 5</td>
</tr>
<tr>
   <td class="date">15th February 2012</td>
   <td class="sent"> 10</td>
</tr>
<tr>
   <td class="date">15th February 2012</td>
   <td class="sent"> 10</td>
</tr>

Desired output from above would be the number “30”.

Try this way:-

var sum = 0;            
var thedate = $(".date:contains('15th February 2012')");

   $(thedate).each(function() {              
    var sents = $(this).next('.sent').text();
    sum = sum + Number(sents);
});

alert(sum);​

Actual problem is with $(sentsnumb). It should be replaced with sentsnumb
