How to add tooltip to table header
17,546
CAUSE
There are multiple issues with your code:
- You have incorrect CSS selectors, you should be targeting
th
elements and nottr
. -
initComplete
is a proper place to do this since you only need to do it once.
DEMO
My example below is for Bootstrap Tooltip. Adjust to your tooltip plugin accordingly.
$(document).ready(function() {
var table = $('#example').DataTable( {
"ajax": 'https://api.myjson.com/bins/qgcu',
"initComplete": function(settings){
$('#example thead th').each(function () {
var $td = $(this);
$td.attr('title', $td.text());
});
/* Apply the tooltips */
$('#example thead th[title]').tooltip(
{
"container": 'body'
});
}
});
});

I'm using jQuery DataTables and I have been trying to add tooltips to the Header column of my datatables for the past 2 days to no avail.
I have used the example on the datatables website where tooltips were added to the row data, but that didn't work. I only see one tooltip, and it does not even get the title of the column.
Below is the code I have so far.
if (oTable != null) { oTable.fnClearTable(); oTable.fnAddData(columnData); } else { oTable = $('#caseDataTable').dataTable({ "bDestroy": true, "aaData": columnData, "aoColumnDefs": columnNames, bFilter: true, bAutoWidth: true, autoWidth: true, "responsive": true, dom: 'Bfltip', buttons: [ { extend: 'colvis', postfixButtons: ['colvisRestore'], collectionLayout: 'fixed two-column' } ], "fnDrawCallback": function() { if (typeof oTable != 'undefined') { $('.toggleCheckBox').bootstrapToggle({}); } $('#caseDataTable thead tr').each(function () { var sTitle; var nTds = $('td', this); var columnTitle= $(nTds[0]).text(); this.setAttribute('title', columnTitle); }); /* Apply the tooltips */ $('#caseDataTable thead tr[title]').tooltip({ "delay": 0, "track": true, "fade": 250 }); } }); }
