I'm using DataTables and also using server side processing (Django).
I have a seperate textfield in which I use it to custom filter data in the DataTable after the table has been rendered already.
The following works just fine (I want to custom filter columns):
var table = $('#problem_history').DataTable( {
"bJQueryUI": true,
"aaSorting": [[ 1, "desc" ]],
"aoColumns": [
// various columns here
],
"processing": true,
"serverSide": true,
"ajax": {
"url": "/getdata",
"data": {
"friend_name": 'Robert'
}
}
} );
So on the page load (initial load of the DataTable) it filters for 'Robert' just fine. But now I want to programmatically change the data to filter for "friend_name" == "Sara"
I already tried the following, the filteredData
has a correct filtered object but the table itself does not redraw with the new filter.
var filteredData = table.column( 4 ).data().filter(
function ( value, index ) {
return value == 'Sara' ? true : false;
}
);
table.draw();
I also tried this but no luck:
filteredData.draw();
How can I achieve this?
Thank you for your help.
Here is a very nice explanation on how to do it: https://datatables.net/reference/option/ajax.data
I am currently using this code:
"ajax": {"url":"/someURL/Backend",
"data": function ( d ) {
return $.extend( {}, d, {
"parameterName": $('#fieldIDName').val(),
"parameterName2": $('#fieldIDName2').val()
} );
}
}
You call it by doing the following:
$('#myselectid').change(function (e) {
table.draw();
});
If you want to submit by clicking on the button, change the .change
to .click
and make sure that ID is pointing to button's id in a HTML
You've almost got it. You just need to assign the filter var to the data parameter that's passed in the datatables request:
"ajax": {
"url": "/getdata",
"data": {
"friend_name": $('#myselectid').val();
}
}
And to filter the data, just call draw()
on the select change event
$('#myselectid').change(function (e) {
table.fnDraw();
});
