Error message "Uncaught TypeError: undefined is not a function" (DataTable)

Question

I have the simple DataTable that should be populated with data using the bellow AJAX call. Except that when the page load, I get the error message "Uncaught TypeError: undefined is not a function"

My Imports

The reason why I have so many imports is because I am working with a very complex datatable.

JavaScript

<script type="text/javascript">
   var contractUrl = "Service.asmx/GetContracts";
   $(document).ready(function() {
    var table = $('#contracts').DataTable({
    dom: 'lBfrtip',
    stateSave: true,
    lengthChange: false,
        buttons: [
            'pageLength','excel'
        ],
    scrollY:        300,
    scrollX:        true,
    scrollCollapse: true,
    columnDefs: [
        { width: 200, targets: 0 }
    ],
    fixedColumns: true,
        stateSave: true,
    "processing": false,
    "serverSide": true,
    "ajax": {
        type: "POST",
        url: contractUrl,
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        },
    "columns": [ 
            { "data": "Code" }, 
            { "data": "ContractType" }],
    "lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
    "pagingType": "full_numbers",
    "searching": false
} );

table.buttons().container()
    .appendTo( $('div.eight.column:eq(0)', table.table().container()) );
});

</script>

Here is my Json

[{"Code":"Dev","ContractType":"GPO"}]

The only syntax error you have is defining the stateSave property twice on the config object.

I tried to initialize with your code + some dummy data i got from their examples.

I had to comment out ajax and columns properties. Also, I had to comment stateSave (both times :) ), but this might have to do with StackOverflow limitations. To be clear: having it once might not be possible on SO. Having it twice is an error and won't work anywhere.

Everything else seems fine, including the table.buttons() .

Because of the duplicated property on config object DataTable() does not correctly initiate and the methods you're trying to access are not exposed.

See it working in this example:

 $(document).ready(function() { table = $('#contracts').DataTable({ dom: 'lBfrtip', // stateSave: true, lengthChange: false, buttons: [ 'pageLength', 'excel' ], scrollY: 300, scrollX: true, scrollCollapse: true, columnDefs: [{ width: 200, targets: 0 }], fixedColumns: true, // stateSave: true, processing: false, // serverSide: true, /* "ajax": { type: "POST", url: contractUrl, data: '{}', contentType: "application/json; charset=utf-8", dataType: "json", }, // replaced with data, below */ data: dataSet(), columns: [ { title: "Name"}, { title: "Position"}, { title: "Office"}, { title: "Extn."}, { title: "Start date"}, { title: "Salary"} ], lengthMenu: [ [10, 25, 50, -1], [10, 25, 50, "All"] ], pagingType: "full_numbers", searching: false }); table.buttons().container().appendTo($('div.eight.column:eq(0)', table.table().container())); }); function dataSet(){return [ ["Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"], ["Garrett Winters", "Accountant", "Tokyo", "8422", "2011/07/25", "$170,750"], ["Ashton Cox", "Junior Technical Author", "San Francisco", "1562", "2009/01/12", "$86,000"], ["Cedric Kelly", "Senior Javascript Developer", "Edinburgh", "6224", "2012/03/29", "$433,060"], ["Airi Satou", "Accountant", "Tokyo", "5407", "2008/11/28", "$162,700"], ["Brielle Williamson", "Integration Specialist", "New York", "4804", "2012/12/02", "$372,000"], ["Herrod Chandler", "Sales Assistant", "San Francisco", "9608", "2012/08/06", "$137,500"], ["Rhona Davidson", "Integration Specialist", "Tokyo", "6200", "2010/10/14", "$327,900"], ["Colleen Hurst", "Javascript Developer", "San Francisco", "2360", "2009/09/15", "$205,500"], ["Sonya Frost", "Software Engineer", "Edinburgh", "1667", "2008/12/13", "$103,600"], ["Jena Gaines", "Office Manager", "London", "3814", "2008/12/19", "$90,560"], ["Quinn Flynn", "Support Lead", "Edinburgh", "9497", "2013/03/03", "$342,000"], ["Charde Marshall", "Regional Director", "San Francisco", "6741", "2008/10/16", "$470,600"], ["Haley Kennedy", "Senior Marketing Designer", "London", "3597", "2012/12/18", "$313,500"], ["Tatyana Fitzpatrick", "Regional Director", "London", "1965", "2010/03/17", "$385,750"], ["Michael Silva", "Marketing Designer", "London", "1581", "2012/11/27", "$198,500"], ["Paul Byrd", "Chief Financial Officer (CFO)", "New York", "3059", "2010/06/09", "$725,000"], ["Gloria Little", "Systems Administrator", "New York", "1721", "2009/04/10", "$237,500"], ["Bradley Greer", "Software Engineer", "London", "2558", "2012/10/13", "$132,000"], ["Dai Rios", "Personnel Lead", "Edinburgh", "2290", "2012/09/26", "$217,500"], ["Jenette Caldwell", "Development Lead", "New York", "1937", "2011/09/03", "$345,000"], ["Yuri Berry", "Chief Marketing Officer (CMO)", "New York", "6154", "2009/06/25", "$675,000"], ["Caesar Vance", "Pre-Sales Support", "New York", "8330", "2011/12/12", "$106,450"], ["Doris Wilder", "Sales Assistant", "Sidney", "3023", "2010/09/20", "$85,600"], ["Angelica Ramos", "Chief Executive Officer (CEO)", "London", "5797", "2009/10/09", "$1,200,000"], ["Gavin Joyce", "Developer", "Edinburgh", "8822", "2010/12/22", "$92,575"], ["Jennifer Chang", "Regional Director", "Singapore", "9239", "2010/11/14", "$357,650"], ["Brenden Wagner", "Software Engineer", "San Francisco", "1314", "2011/06/07", "$206,850"], ["Fiona Green", "Chief Operating Officer (COO)", "San Francisco", "2947", "2010/03/11", "$850,000"], ["Shou Itou", "Regional Marketing", "Tokyo", "8899", "2011/08/14", "$163,000"], ["Michelle House", "Integration Specialist", "Sidney", "2769", "2011/06/02", "$95,400"], ["Suki Burks", "Developer", "London", "6832", "2009/10/22", "$114,500"], ["Prescott Bartlett", "Technical Author", "London", "3606", "2011/05/07", "$145,000"], ["Gavin Cortez", "Team Leader", "San Francisco", "2860", "2008/10/26", "$235,500"], ["Martena Mccray", "Post-Sales support", "Edinburgh", "8240", "2011/03/09", "$324,050"], ["Unity Butler", "Marketing Designer", "San Francisco", "5384", "2009/12/09", "$85,675"] ];}
