    Got this error when I added the property scrollY.


    Could someone help me with this. Used 1.10.18 version

    I'm using the node.js datatable editor library. When trying to filter the select options depending on a specific user_id ... I'm getting TypeError: this.where is not a function

    I already posted the issue on SO ... https://stackoverflow.com/questions/54012451/node-js-datatables-editor-filter-select-option-depending-on-a-certain-value

    How do I get to filter the option values in editor for node.js?

    I would like to load data into a DataTable using "Child rows" attached to a parent table from a MongoDB data source. MongoDb allows for embedded documents as arrays and/or JSON objects. Some of that data will have the same structure as the sample AJAX used in the "Child rows" example page, with the exception that the name "data" might be "subcontractor" or "manager" instead . The following shows the start of the example AJAX with the name "data":

    "data": [
    {
    "id": "1",
    "name": "Tiger Nixon",
    "position": "System Architect",
    "salary": "$320,800",
    "start_date": "2011/04/25",
    "office": "Edinburgh",
    "extn": "5421"
    }

    I have no problems using the example JavaScript and AJAX data as long I don't modify the spelling for the name "data" in the source data. When I tried changing "data" to "subcontractor" or "data2" the DataTable wouldn't work. I tried modifying the JavaScript below by changing any reference to "data" to "subcontractor" or "data2" with no results. What do I need to change in the sample JavaScript below to use a different name than "data" in my source JSON?

    $(document).ready(function() {
    var table = $('#example').DataTable( {
    "ajax": "../ajax/data/objects.txt",
    "columns": [
    {
    "className": 'details-control',
    "orderable": false,
    "data": null,
    "defaultContent": ''
    },
    { "data": "name" },
    { "data": "position" },
    { "data": "office" },
    { "data": "salary" }
    ],
    "order": [[1, 'asc']]
    } );

    This is the link to the"Child rows" sample page:

  • 12/19/18--08:23: Bug Fix for columns.adjust()
  • There is a bug in the columns.adjust() function that can cause columns to extend past the scroll bar (if using scrollY) or past the right edge of the table in some cases. This behavior will happen when using the style table-layout: fixed, allowing table cells to shrink smaller than the text they contain, and setting a column width to 0%. I have created a JS Bin showing the behavior as well as the reason it happens: live.datatables.net/rumomuze/1/edit. The reason being that setting the width of a th to 0% has a different behavior than setting the width to 0px. When the cell is set to 0px it will still be rendered, consuming an amount of space determined by it's padding, margin and border. However, when the cell is set to 0% padding, margin and border are ignored and the column is not rendered at all.

    The culprit of this bug is the function _fnCalculateColumnWidths. In this function the datatable DOM instance is cloned and the columns of the cloned table are set to the column property sWidthOrig. If one of the columns sWidthOrig is 0% the cloned table's column is set to 0%, then the original table columns are calculated in px from that. This means that the px width for the other columns (those that aren't 0% width) are calculated with the 0% column not being rendered. When the calculated widths are applied to the original table the 0% column is set to 0px and suddenly has some width that didn't exist when the other columns were calculated, thus the original table is now larger than expected and extends beyond it's right boundary. The fix I am using for this involves calculating a sum of the padding, margin and border for any columns that are set to 0% and removing this space from the size of the cloned table. See the excerpt below:

    /**
    * Calculate the width of columns for the table
    *  @param {object} oSettings dataTables settings object
    *  @memberof DataTable#oApi
    */
    function _fnCalculateColumnWidths ( oSettings )
    {
    
    ...
    
    // Apply custom sizing to the cloned header
    headerCells = _fnGetUniqueThs(oSettings, tmpTable.find('thead')[0]);
    
    var hiddenWidth= 0;
    for (i = 0; i < visibleColumns.length; i++) {
        column = columns[visibleColumns[i]];
        if (/^0*\.?0*%$/.test(column.sWidthOrig)) {
            var header = $(column.nTh);
            hiddenWidth += header.width() === 0 ? header.outerWidth() :
                (header.css("padding-left") + header.css("padding-right") + header.css("margin-left") +
                 header.css("margin-right") + header.css("border-left-width") + header.css("border-right-width"));
        }
        headerCells[i].style.width = column.sWidthOrig !== null && column.sWidthOrig !== '' ?
            _fnStringToCss(column.sWidthOrig) :
            '';
    
    ...
    
    // When scrolling (X or Y) we want to set the width of the table as 
    // appropriate. However, when not scrolling leave the table width as it
    // is. This results in slightly different, but I think correct behaviour
    if (scrollX && scrollXInner) {
        tmpTable.width(scrollXInner);
    }
    else if (scrollX) {
        tmpTable.css('width', 'auto');
        tmpTable.removeAttr('width');
    
        // If there is no width attribute or style, then allow the table to
        // collapse
        if (tmpTable.width() < tableContainer.clientWidth && tableWidthAttr) {
            tmpTable.width(tableContainer.clientWidth);
        }
    }
    else if (scrollY) {
        tmpTable.width(tableContainer.clientWidth);
    }
    else if (tableWidthAttr) {
        tmpTable.width(tableWidthAttr);
    }
    
    //Remove width that was displaced by columns with 0% width
    tmpTable.width(tmpTable.width() - hiddenWidth);
    
    ...
    
    }

    Using the scroller extension with an xhtml document causes an exception when the table has less than 3 rows. The offending code is on line 1029 of the Scroller 1.5.1 source: https://github.com/DataTables/Scroller/blob/1.5.1/js/dataTables.scroller.js.

    This error is caused by invalid xml due to a &nbsp; character reference.

    Changing the named entity to the numbered entity (&#160;) has fixed the error in my local setup.

    Hello All,

    I need an example for Infinite Scroll.
    For example: - At first, there are 20rows in datatable. After I scroll down there should be an ajax call that should get next 20rows and display it.
    Can anyone send the example for that

    Thanks,
    Abhi R

    I'm using the node.js datatable editor library. When trying to do a complex left join 'portfolios_isin_mm.isin AND (securities.mic = portfolios_isin_mm.mic)' ... like this:

        let editor = new Editor( db, 'portfolios_isin_mm' )
            .fields(
                new Field( 'portfolios_isin_mm.account_id' ),
                new Field( 'portfolios_isin_mm.user_id' ),
                new Field( 'portfolios_isin_mm.uid_foreign' )
                new Field( 'securities.issuer_name' ),
                new Field( 'portfolios_isin_mm.isin' ),
                new Field( 'portfolios_isin_mm.mic' ),
               )
    
            .leftJoin( 'portfolios_isin', 'portfolios_isin.id', '=', 'portfolios_isin_mm.uid_foreign' )
            .leftJoin( 'securities', 'securities.isin', '=', 'portfolios_isin_mm.isin AND (securities.mic = portfolios_isin_mm.mic)' );
            //.leftJoin( 'securities', 'securities.isin', '=', 'portfolios_isin_mm.isin' );
    

    I'm getting an error. Debugging the error shows me:

    How can I get the complex left join to work in node.js as well?

    ... I'm using $ node -v ... v10.15.0 and "datatables.net-editor-server": "^1.8.1"

    I know how to create different editors and how to have one button for creating type A with editor A and another for type B, but how can I edit a table entry and get the correct editor?

    Simple example:

    Name, Type, Amount
    Name 1, Type A, 100
    Name 2, Type B, 200
    Name 3, Type A, 150

    That is, if I edit "Name 1" or "Name 3" I get the editor A and if I edit "Name 2" I get editor B.Is there an event for pre-open the editor that I can catch?

    Also, the ideal idea would be to be able to switch editor by catching a type combobox change event, like a tabbed editor. If I could do that, I would only need one button and let the combobox be the event driver.

    Hello Team,

    Is it possible to show document link in DataTable record along with its preview?
    If yes, kindly share example.

    Hey Guys,
    i have a little problem with the integration of the deepLink plugin into my existing table.

    This is my original table

    $(document).ready(function() {
       var dataTable = $('#mytable').DataTable( {
          "iDisplayLength": 30,
          "pagingType": "full",
          "ajax": "Database.txt",
       } );
    } );
    

    Now my table looks like this.

    $(document).ready( function () {
       $('#mytable').DataTable( $.fn.dataTable.ext.deepLink( [
          'search.search'
           ] ) 
       );
    });
    

    So where do i have to place my settings, for example.

    "iDisplayLength": 30,    or
    "pagingType": "full",    or
    "ajax": "Database.txt",
    

    Does anyone know that ?
    I know its a dumb question but i don't get it.
    Thx Samu
