I am trying to write a function to check if any of the table rows are selected.
I need this function to be triggered at any <tr> click.
Thank you.
Here is my code for selecting rows:
$('#Request tbody').on('click', 'tr', function () {
if ($(this).hasClass('selected')) {
$(this).removeClass('selected');
} else {
oTable.$('tr.selected').removeClass('selected');
$(this).addClass('selected');
}
});
As of Datatables 1.10, there is an any() method that can be used:
var table = $('#example').DataTable();
if ( table.rows( '.selected' ).any() )
// Your code here
You have answer in your question already. The code below would let you determine if there are any selected rows.
var $rows = oTable.$('tr.selected');
// If some rows are selected
if($rows.length){
// Otherwise, if no rows are selected
} else {
}
I assume that somewhere in your code you have var oTable = $('#Request').DataTable(). Otherwise you can use $('#Request').DataTable().
var table = $('#foo-table').DataTable();
var selectedRows = table.rows({ selected: true });
This is proper way to get the selected rows as of DataTables 1.10.8.
Using the API.
var oTable = $("#yourtable").DataTable();
anyRowSelected = oTable.rows({selected : true}).indexes().length === 0 ? false : true;//false - nothing selected. true - 1 or more are selected.
