问题:

I'm using jQuery DataTables and want to copy all rows (save in JavaScript array) upon clicking the header checkbox.

I want to find where jQuery DataTables store the HTML for remaining page of rows, so I can navigate through JavaScript then check it there or set property checked to true.

Something like this one.

Other information:

I use data from an ajax source(serverside:false), all data is returned.
When I click page 1, all the rows remain Checked.

SOLUTION

There are many methods that could be used for that purpose. You can use rows().data() to get the data for the selected rows.

Example:

var table = $('#example').DataTable();

var data = table
    .rows()
    .data();

alert( 'The table has ' + data.length + ' records' );

DEMO

See this jsFiddle for code and demonstration.

I find the generated element by jQuery DataTables using this code, and I can copy the whole tr element that hides when paging the DataTables.

$('#example').DataTable().rows().iterator('row', function(context, index){
    var node = $(this.row(index).node()); 
    //node.context is element of tr generated by jQuery DataTables.
});
