Datatables remove this !!~ it doesnt return
Regarding in this sample
I dont understand whats the use of this !!~
This is the script in fiddle
$.fn.dataTable.ext.search.push(
function(settings, data, dataIndex) {
var tdValues=[];
var $tds=table.row(dataIndex).nodes().to$().find('td');
$tds.each(function(){
var $this=$(this);
var hasSelect=$this.find('select').length >0; // check if current cell has a select box
var curTdValue= hasSelect ? $this.find('option:selected').text() : $this.text();
tdValues.push(curTdValue);
});
var rowValues=tdValues.join(' ');
return !!~rowValues.toLowerCase().indexOf(table.search().toLowerCase()); //<---this area
}
);
If I remove the !!~ It doesnt return. I cant see it in the manual of datatables about this also this $.fn.dataTable.ext.search.push I cant also see this in their manual.
EDITED
This answered the tilde or ~ but how about this? $.fn.dataTable.ext.search.push
