Question

I have table with numbers tht needs to be summarize.
Example:

<td class="mcost_el.entry[0]">93,08</td>
<td class="mcost_el.entry[1]">544,33</td>

How get all values of td elements with class mcost_el.entry[] and summarize it?

For inputs i’m use $('#d1').attr("value");. Is suitable for this task? (by adding value=”” for td)

Answer 1

You can use .text() rather than what you have suggested.

Update your HTML to

<td class="mcost_el">93,08</td>
<td class="mcost_el">544,33</td>

Add in javascript for

var _total = 0;

$(function(){
    $('.mcost_el').each(function(){
         _total += parseFloat($(this).text()); // will give you the value.
    });
});

Also, rather than using .attr("value") in the future, you can just use .val()
