$('.views-table').children('tbody').children('tr').each(function(i){

//下面这个就是each的长度

alert($('.views-table').children('tbody').children('tr').size());
//取得每个td内的值

var oneTdfloatValue = parseFloat($(this).children('td').eq(2).html())*1000000000000;

oneTdfloatValue = judgeIsNaN(oneTdfloatValue);

tdvalue = tdvalue+oneTdfloatValue;

});
