How to get value of td elemets on JQuery?

I have table 开发者_如何学Cwith 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)

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()

var tdtotal = 0;
$("td[class^='mcost_el.entry[']").each(function() {
    tdtotal += parseInt($(this).text().replace(",","")); 
})
alert(tdtotal);

I'm not quite sure i'm answering correctly here, its unclear if you are seeking a way to get text from a TD element, or wether your having trouble targetting all td's with a certain class (selector issues)

.attr("value") or better .val() is for input fields

if you want to get text from a TD element, you should be using:

$('td').text();
