Make table on page load empty?

Make table on page load empty?

webmanwebman Posts: 5Questions: 1Answers: 0

I have a datatable that I am returning from a mysql database. I would like the table to be empty at first page load then load based on my filter radio buttons. Can I do this? Not sure where to place the clear() tag, then the draw tag?

    Just set the default of your filter radio buttons to filter out everything. Then you won't see anything in the front-end. Once the user changes the radio buttons your filter should be less restrictive.

    This is one way to use search.push: https://datatables.net/examples/plug-ins/range_filtering.html

    And here is another one that allows you to get hold of individual rows:

    On page load brings back everything in my query, should I have a default radio on the page load that clears everything? Or should I filter everything out on the actually table until a user choose something, sorry a little confused by your answer.

    I would recommend the latter. Leave your back end query unchanged and filter all records on the client side. Initially just filter out everything. The filtering I suggest is client side only. No changes on the back end!

    Can you supply the syntax?

    On the table or add a new radio button

    where do I hide the table at first load? Driving me nuts everything I try it doesnt work?

    $(document).ready(function() {
    oTable = $('#example').dataTable({
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "iDisplayLength": 25,
    "aLengthMenu": [[25, 50, 100], [25, 50, 100]],
    responsive:true,
    });
    $('div.container').removeClass('hidden');
    } );

    This looks like the old syntax. No experience with that.

    You need to use an event to hide the table initially. I thought you only wanted an empty table. Then you wouldn’t have needed it.

    I really want to hide the table on page load, maybe using DIV, then on click using my radio display the table.

    here is an example from my own coding. I am using multiple tables on the same page and show and hide them dynamically based on events.

    When I iniitalize the first table I hide all others

    contractGovDeptTable
            .on ('init', function () {
                hideTbls( [contractTable, contractFixedTable,
                           contractVariableTable, cashFlowTable, contractRfaGovTable] );
        })
    
    function hideTbls(tbls) {  //array of table objects
        $('.headers').addClass('hidden');
        for (i=0; i < tbls.length; i++) {
            $(tbls[i].table().container()).addClass('hidden');
        }
    };
    
    
    $('#yourButton').click(function () {
        showTbls( [contractTable, contractFixedTable,
                           contractVariableTable, cashFlowTable, contractRfaGovTable] );
    });
    
    function showTbls(tbls) { //array of table objects
        $('.headers').removeClass('hidden');
        for (i=0; i < tbls.length; i++) {
            $(tbls[i].table().container()).removeClass('hidden');
        }
    };
    

    The above could be something for you.

    Put it in a div which has display:none, then use $('div.myContainer').css('display', 'block'); when you want to show it. You can dynamically add data to a table using rows.add().
