Data Tables Custom View then export to csv - problem

yooelton

Hello and thanks for interesting in my problem.

I've got implemented database with datatables for equipment in company.

The problem is when I export my data to csv. Always every row is included into the csv file(I open it with excel), even when i custom view only a few of columns.

$( "#custom_print_view" ).dialog({
                   autoOpen: true,
                   modal: true,
                   height:400,
                   width:350,
                    buttons: {
                    "Show": function() {

                            $("#empty").dialog("close");
                            toShow.elements.push("inTime");
                            toShow.data = $("#custom_print_date").val();
                        if(toShow.elements.length >= 1){
                            $.post( baseUrl+"CustomPrint/download",{toShow: JSON.stringify(toShow)}).done(function(data){
                            data = JSON.parse(data);
                            columns = elementsToTable(toShow.elements);
                            update(data,columns);
                            //data = JSON.parse(data);

                            $('#exportLink').css('display', 'inline-block'); //show button when ready 
                            var filename = 'hardware.csv'; //export .csv file           
                            var blobby = new Blob([makeCSV(data)], {type: 'text/csv;charset=utf-8'}); //make blob object

                                    $(exportLink).attr({
                                                'download' : filename,
                                                'href': window.URL.createObjectURL(blobby),
                                                'target': '_blank'
                                                });

                            })
                    }
                    else{
                            $("#empty").dialog("open");

                        }

                            $(this).dialog("close");
                        }
                    }
            });

        function update(data,columns){
                    var result='';
                    table = $('#Date').DataTable({

                    "pagingType": "simple",
                    "lengthMenu": [[50, 100, 150,200, -1], [50, 100, 150,200, "All"]],
                    "data": data,
                    "destroy": true,
                    "order": [[ 1, "asc" ]],
                    "scrollY": ($(window).innerHeight()-300)+"px",
                    "scrollCollapse": true,
                    "paging":         true,
                      "columns": columns,
                      "columnDefs": [ {


                            "targets": 0,

                            "render": function ( data, type, full, meta ) {
                                if(data!=null)
                                    {
                                       return data.replace('"',"'");
                                    }
                                else{
                                    return data;
                                    }

                            }
                          } ]

                    })  

        }

Where is the problem? I found on examples that it can work, and export only things that i searched through the search box or only the custom view with defined columns.

Please help me or ask me to copy other lines of code.

Cheers

I don't actually see where you are defining the CSV button for the Buttons extension. Is that is separate code?

function makeCSV(arrObj) {
        var jsonArray = typeof arrObj != 'object' ? JSON.parse(arrObj) : arrObj;
        var fullStr = '';
        var partialStr='';
        fullStr='\ufeff';
          for (var i = 0; i < jsonArray.length; i++) {
                var oneLine = '"';
                   for (var j in jsonArray[i]) {
                      if (oneLine != '"') oneLine += '";"'

and in another files .php there is:
<a id="exportLink">Export to CSV</a>

yooelton

i've got it physically, problem is its data is not updating due to searching datables by search box

allan

It looks to me like you are making a request to the server to get the data to export, so I don't really see how DataTables' filtering would come into play. You'd need the server to filter the data if you are getting it from there.
