('input:checkbox').click(function(e){ var total = 0;

('input:checkbox').click(function (e) { var total = 0;

("tr:has(:checkbox:checked)td:nth-​​child(" + columnIndexValue +)").each(function(){ 总计+ = parseInt(

("tr:has(:checkbox:checked) td:nth-child(" + columnIndexValue + ")").each(function () { total += parseInt(
