Individual column searching not working.

Hi,

Can anyone see what is wrong with this?
Following the example from : https://datatables.net/examples/api/multi_filter_select.html

The selects are appearing but the search is not doing anything. No errors in the console.

Thanks,

Mick

$(document).ready(function () {

    "bFilter": false,

    Search has been disabled. Remove that and it should work.

    Yes, thanks.

  • MickBMickB Posts: 103Questions: 25Answers: 2

    Is there an example where the selects have been moved to the top?

    edited July 2017

    Got it:

    var select = $('<select onclick="stopPropagation(event);"><option value=""></option></select>')
    
  • MickBMickB Posts: 103Questions: 25Answers: 2

    Ahhh, now I need to filter the other selects, after I have applied a filter.

    I will have a go at that.

  • MickBMickB Posts: 103Questions: 25Answers: 2

    This doesn't look this easy, has anyone done this?

    When a value is selected, the rows are filtered. I then want to update the other selects, so that they reflect the filtered columns.

    Does that make sense?

    Eg,

    Customer No Name
    CHU027 A
    CHU027 B
    WAH001 C
    WAH001 D

    When CHU027 is selected, only A and B are shown in the select for the Name filter.

    Happy to move this to paid support.

    I wrote this example a while back showing how the filters can be updated when an item is selected in another filter: http://live.datatables.net/gejojiqu/1/edit .

    Hi Allan,

    I have this working now, but I have a slight problem with the table headers. My filters are at the top and this is affecting the column name spacing.

    https://ibb.co/m1OA4a

    Any idea where I can start with this? Is just adding right and left padding to th the best way?

    This is where I add them:

      <thead>
        <tr>
            {{--This is the column headers--}}
            @foreach($neatHeaders as $neatHeader )
                <th>
                    @if($neatHeader != 'Row Highlight') {{--Skip this one, it's just used to add--}}
                    {{ $neatHeader }}
                    @endif
    
                </th>
            @endforeach
    
        </tr>
    
        @if ($filters == 1)
            <tr>
                {{--This is the column filters--}}
                @foreach($neatHeaders as~~~~ $neatHeader )
                    <th>
                        @if($neatHeader != 'Row Highlight') {{--Skip this one, it's just used to add--}}
                        {{ $neatHeader }}
                        @endif
    
                    </th>
                @endforeach
    
            </tr>
        @endif
    
        </thead>

    Try using the orderCellsTop option.

                                column
                                    .search(val)
                                    .draw();
                        });
                        column.data().unique().sort().each( function ( d, j )
                        {
                            select.append( '<option value="'+d+'">'+d+'</option>' );
                        } );
    

    Thanks in advance :)

    As serverSide is false, all the data will be in the table from the start. So, you're using initComplete already, you just need to add the

    table.on( 'draw', function () {
        buildSelect( table );
      } );
    

    code in there too, to ensure the table is updated with each draw.

    Hi Colin, AMAZING!
    I put all my code in to trash and use your code as base and everything its working very well.
    The only thing I detected for now is, when I create a limite on wich colunm I want the select filter displays, table.columns([2,3,4,5,6,7])

    The select filter doesnt work well.

    function buildSelect(table) {
            table.columns().every(function() { // table.columns([2,3,4,5,6,7]) ao colocar as colunas que quero deixa de ter smart filter
                var column = table.column(this, {
                    search: 'applied'
                });
                var select = $('<select><option value=""></option></select>')
                    .appendTo($(column.footer()).empty())
                    .on('change', function() {
                        var val = $.fn.dataTable.util.escapeRegex(
                            $(this).val()
                        );
    
                        column
                            .search(val ? '^' + val + '$' : '', true, false)
                            .draw();
                    });
    

    FORGET THIS POST, FIXED!
    I just selected the wrong columns.

    Once again Colin, thanks for help me out :)

  • nelsondcostanelsondcosta Posts: 13Questions: 0Answers: 0

    Hi Colin, how are you?

    Its hard to doa multiple filter?
    I want to select option A and B and the next filters give me just the information about A and B
    Like the post above

    Hi colin,

    Well you helped me out doing something like this = http://live.datatables.net/deboparo/1/edit

    And it work very well

    My ideia is, being able to select more options per filter like Accountant and Developer
    and the others filters only show up the options left.

    Im not sure if i explained right :/

    I tried adapt using this = http://live.datatables.net/xehexoye/1/edit
    And I just fail hard in my code :'(

  • colincolin Posts: 8,013Questions: 0Answers: 1,348

    Your last test case looks good to me - the select2 is working as expected and is filtering correctly! Can you explicitly say what it's doing wrong, and what you would expect it to do instead, please.

    Can you put this together in a test case so we can see what is happening? Scanning a bunch of code is difficult to do. All you need to do is provide the essential code to show the issue.

    Well mate, i cant put it work with JS BIn (im new)
    http://live.datatables.net/wahowodu/2/

    In my xampp

    If might help you I can share my code.

  • nelsondcostanelsondcosta Posts: 13Questions: 0Answers: 0

    Hi mates, I just edited inside JS bin and now works +/-
    http://live.datatables.net/kefojuse/3/edit

    Can help me out how to use select 2?
    For now I can only select 1 option, need 2 or more.

  • nelsondcostanelsondcosta Posts: 13Questions: 0Answers: 0

    The select 2 option its link this -> http://live.datatables.net/xehexoye/1/edit

  • kthorngrenkthorngren Posts: 8,082Questions: 25Answers: 1,816

    Here is your updated example with select2:
    http://live.datatables.net/nebujaya/1/edit

    Changes made:
    1. Added the select2.js and css libraries.
    2. Replaced the code with the select2 code from the example.
    3. Changed the appendTo() selector to match what you have in your regular select example.
    4. Commented you this code in initComplete:

                table.on('draw', function() {
                    //buildSelect(table);
                });     
    

    Commented out the code to update the select options because it causes a stack overflow error. A different solution will need to be created to handle updating the select options using select2. Here is the select2 docs for programmatic control of select2:
    https://select2.org/programmatic-control/add-select-clear-items

    I don't have an example of updating the select2 options. Someone on the forum may but you might need to look on Stack Overflow and the select2 docs to learn how to update the select2 options. If I have time later I'll look but no promises.

    I also noticed that you have two sets of sorting icons. This is due to conflicting CSS files. I commented out the jquery.dataTables.min.css include to fix your styling issues.

    Hi kthorngren, thanks alot it work :)

    Just a question plz. There is any way to when I pick "London and Sidney"
    The others filters"pre-filter" the option available for "London and Sidney"???

    Once again thanks :)

  • kthorngrenkthorngren Posts: 8,082Questions: 25Answers: 1,816

    The others filters"pre-filter" the option available for "London and Sidney"???

    That is what I mentioned above. The docs for select2 will need to be reviewed to learn how to do this.
