How to delete all rows to refresh data?

GeasLu

Hi at all,
i use a datatable to show some details-data in a modal form. When the user click on a person, the datatable shown his details-data, like name, surname, date born... so everytime he change the data, the datatable have to change.

Now I'm using :
in the top of my function

var dtb;  

then in the ajax-jquery-call:

success:
 dtb =  $('#' + pIdDataTable).DataTable({
                        destroy: true,
                        responsive: true,
                        data : elnParamOspite,
                        dataSrc : "ElnParametriOspite",
                        selectType : "row",
                        columns: [
                            { // 0
                                data: "ID_ROW",
                                title : 'ID_ROW',
                                visible : false
                            },
....etc...

to initialize my datatable, every time the modal closed and change person select.

Everything it's ok, but when i have to read which row is clicked with this function:

    $('#' + pIdDataTable).on('click', 'tbody td', function () {

        let indRow = this._DT_CellIndex.row;
        var indCol = this._DT_CellIndex.column;
        var idUserLogin = $('#idUserLogin').val();

        if (indRow > -1) {
            var rowData = dtb.row(this).data();    <---------------------------------------- HERE IS THE ERROR

            switch (dtb.column(indCol).header().textContent){

....etc....

there was an error:

"dtb is undefined"

can anyone help me?

thanks

I suspect the variable dtb is out of scope. We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

Cheers,

Colin
