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');
})
});
回答2:
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);
}
});
