I have a jquery datatable which I am showing on UI. I want to apply filter on the datatable data and store the filtered data into a variable (not looking for filtering the data on UI).
I tried the below code but it returns the same rows as that of the original datatable.
var filteredData = $('#table').DataTable().column(1).filter( function ( value, index ) {
return value == 'test' ? true : false;
} ).data();
$('#table').DataTable().column(1).filter( function ( value, index ) {
console.log("VALUE: " + value);
console.log("INDEX: " + index);
} ).data();
This is showing next, is not correct:
VALUE: 1 INDEX: 0
So... change to this:
var filteredData = $('#table').DataTable().column(1).data().filter( function ( value, index ) {
return value=="P";
}).toArray();
console.log("FILTERED DATA: " + filteredData);
This is showing next:
FILTERED DATA: P,P
As you can see, this only stores the column that you are filtering... If you want to store other column (and in general), I would use this other method ( Reference ):
var array = [];
$('#table').DataTable().rows().every( function ( rowIdx, tableLoop, rowLoop ) {
var data = this.data();
if (data[1] == "P"){
array.push(data[5])
}
// ... do something with data(), or this.node(), etc
} );
console.log(array);
As you can see, this stores the value of column 5 filtering by column 1.
