Вы должны получить общее количество строк в DataTable не строки на определенной странице. ??? Но вы получаете общее количество строк - его 42 ... – Legionar

Кажется, кто-то спросил об этом уже. http://stackoverflow.com/questions/1149958/jquery-count-number-of-rows-in-a-table – dmigo

@Chesheersky Нет, это другое ... это данные, а не количество строк в HTML-таблица ... – Legionar

У вас есть 42 строк в вашем примере. Но ваш PageSize 10.

Чтобы получить PAGESIZE, вы можете использовать это: https://datatables.net/reference/api/page.len()

Может быть, это помогает сделать вещи яснее:

$(document).ready(function() { 
    var table=$('#example').dataTable({"pageLength": 30}); 
    var tbl = $('#example').DataTable(); 
    alert(JSON.stringify(tbl.page.info())); 
});

Я редактировал свой jsfiddle пример: https://jsfiddle.net/6w8nbhr1/1/

добавить это в DataTable варианты

var table = $('#datatable_fixed_column') 
       .DataTable({ 
columns: [{....}], 
"ajax": {....}, 
"initComplete": function (settings, json) {//here is the tricky part 
        var count = $('#my-table tr').length-1 
        $(".badge").html(count); 
       }

initComplete будет выполняться, когда ваша таблица полностью инициализирован,

так с помощью JQuery Получить все tr затем -1 для заголовка

Пожалуйста, скажите мне, где это неправильно, поэтому я могу улучшить сообщение –
