How can I select all checkboxes from all the pages in a jQuery DataTable

问题

I have HTML page which have multiple checkboxes and individually they can be checked. I have button for "Select All" and when I click on this button all the checkboxes should get selected, and when I click again on the same button all the checkboxes should get deselected from all pages.

In my original program there are thousands of records, but at a time 10 records are getting display, but when user click on select it should select all thousands record.

I am using jQuery Datatables plug-in for displaying the data. It provides pagination, searching, sorting etc. so at a time I am displaying only 10 records on my current page. if I click on next or page number which is provided by Bootstrap Datatable another 10 records will be displayed. As mention in the problem I want to select all check-boxes from all the pages.

$(document).ready(function () {
   $('body').on('click', '#selectAll', function () {
      if ($(this).hasClass('allChecked')) {
         $('input[type="checkbox"]', '#example').prop('checked', false);
      } else {
       $('input[type="checkbox"]', '#example').prop('checked', true);
       }
       $(this).toggleClass('allChecked');
     })
});

回答1:

Try this code instead:

$(document).ready(function () { 
    var oTable = $('#example').dataTable({
        stateSave: true
    });

    var allPages = oTable.fnGetNodes();

    $('body').on('click', '#selectAll', function () {
        if ($(this).hasClass('allChecked')) {
            $('input[type="checkbox"]', allPages).prop('checked', false);
        } else {
            $('input[type="checkbox"]', allPages).prop('checked', true);
        }
        $(this).toggleClass('allChecked');
    })
});

The magic should happen in fnGetNodes():

fnGetNodes(): Get an array of the TR nodes that are used in the table's body

Edit

This alternative solution is mostly for debugging (to see if it works). Hardly optimal code:

$(document).ready(function () { 
    var oTable = $('#example').dataTable({
        stateSave: true
    });

    var allPages = oTable.cells( ).nodes( );

    $('#selectAll').click(function () {
        if ($(this).hasClass('allChecked')) {
            $(allPages).find('input[type="checkbox"]').prop('checked', false);
        } else {
            $(allPages).find('input[type="checkbox"]').prop('checked', true);
        }
        $(this).toggleClass('allChecked');
    })
});

Use datatable $ instance for selections https://datatables.net/docs/DataTables/1.9.4/#$

$(document).ready(function () { 
    var oTable = $('#example').dataTable({
        stateSave: true
    });

    $("#selectAll").on("change", function(){
        oTable.$("input[type='checkbox']").attr('checked', $(this.checked));  
    });
});

回答3:

Try This,

   if ($(this).hasClass('allChecked')) {
     $('input[type="checkbox"]').prop('checked', 'checked')
   } else {
     $('input[type="checkbox"]').prop('checked', 'false')
   }

DEMO

Easiest way is to use following jQuery code:

//EDIT on the second click, you now remove all checked boxes.

$('#selectAll').click(function(e) {
    if($(this).hasClass('checkedAll')) {
      $('input').prop('checked', false);   
      $(this).removeClass('checkedAll');
    } else {
      $('input').prop('checked', true);
      $(this).addClass('checkedAll');
    }
});

回答5:

use dataTables.checkboxes.min.js and use "selectAllPages" : false . It should be work for selection of each page records .

回答6:

var oTable = $('#myTable').DataTable({
    lengthMenu: [[10, 25, 50, -1], [10, 25, 50, 'All']]
    // stateSave: true
});
$('#selectAll').on('change', function() {
    oTable.$('.student_id:checkbox').prop('checked', $(this).prop('checked'));
});

jQuery(document).on('change', '.student_id', function() {
    if (jQuery(this).is(':checked')) {
        if (jQuery('.student_id:checked').length == jQuery('.student_id').length) {
            jQuery('#selectAll').prop('checked', true);
        } else {
            jQuery('#selectAll').prop('checked', false);
        }
    } else {
        jQuery('#selectAll').prop('checked', false);
    }
});
