在函数中检索 Bootstrap table 中的所有计数器值
Retrieve in function all counter values from a Bootstrap table
这里我有一个 table 的示例，它显示每页 10 行的 25 条记录的列表。
当我应用过滤器“印度”时，如何在函数中获取更新的计数器指示值？
我有显示值，但没有条目数和总条目数。
这是一张用于直观解释的图片。
这是 HTML 代码和函数，只有我才能获得第一个计数器。

因为您正在使用 Datatables.net，所以您可以使用 Javascript 中的数据表 API 来获取此信息：
var myTable = $('#myTable').dataTable();
var fromRecord = ((myTable.page() * myTable.page.len()) + 1);
var toRecord = ((myTable.page() + 1) * myTable.page.len());
var entries = "?";
var totalentries = myTable.rows().count();
var message = "Showing: " + fromRecord + ' to ' + toRecord;
message += "\nEntries: " + entries;
message += "\nTotal Entries: " + totalentries;
alert(message);
有关详细信息，请查看 Datatables API reference
您可以使用 page.info() API of DataTable
$(document).ready(function() {
var table = $('#myTable').DataTable({})
$("#btnGetallCount").click(function() {
console.log(table.page.info());
var page_info = table.page.info();
var showing = page_info['end'];
var entries = page_info['recordsDisplay'];
var totalentries = page_info['recordsTotal'];
var message = "Showing: " + showing;
message += "\nEntries: " + entries;
message += "\nTotal Entries: " + totalentries;
alert(message);
