In my project I am loading data to the data table from server side. First load is perfectly working fine. But when I change the <select> <option>
value it is giving me an error.
I have a <select> <option>
panel. So, once I change the option I need to remove current content and load different content to the table. I am getting data from ajax call and loading to the table. The second time when I change the option, it is giving me this error.
DataTables warning: table id=example - Cannot reinitialise DataTable. For more information about this error, please see http://datatables.net/tn/3
I checked the URL given but there is no good sound for me.
Here is my HTML,
<table id="example" class="table table-striped table-bordered nowrap" cellspacing="0" width="100%" style="background:#f3f3f3">
<thead>
<tr>
<th><div class="heading">Title 01</div></th>
<th><div class="heading">Title 02</div></th>
<th><div class="heading">Title 03</div></th>
<th><div class="heading">Title 04</div></th>
<th><div class="heading">Title 06</div></th>
<th><div class="heading">Title 07</div></th>
</tr>
</thead>
<tbody></tbody>
</table>
Here is the select option dropdown
<select name="exampleSelect" id="exampleSelect" class="exampleSelect">
<option id="exam1">value</option>
<option id="exam2">value</option>
<option id="exam3">value</option>
<option id="exam4">value</option>
<option id="exam5">value</option>
<option id="exam6">value</option>
<option id="exam7">value</option>
</select>
This is my on change function,
$('select#exampleSelect').on('change', function() {
var sId = $(this).children(":selected").attr('id');
loadedData(sId);
});
Here is my loadedData function
function loadedData(sId) {
var table = $('#example').DataTable({
"processing": true,
"serverSide": true,
"ajax": {
"url": "ajaxdata.json",
"type": "POST"
},
"sScrollY": "300px",
"scrollX":true,
"paging": false,
"bFilter": false,
"bInfo": false,
"searching": false,
"bSort" : false,
"fixedColumns": true
});
}
Here accroding to the "sId", loading data is changing
This is my JSON data,
{
"draw": 1,
"recordsTotal": 57,
"recordsFiltered": 57,
"data": [
["Airi", "Satou", "Accountant", "Tokyo", "28th Nov 08", "$162,700"],
["Angelica", "Ramos", "Chief Executive Officer (CEO)", "London", "9th Oct 09", "$1,200,000"],
["Ashton", "Cox", "Junior Technical Author", "San Francisco", "12th Jan 09", "$86,000"],
["Bradley", "Greer", "Software Engineer", "London", "13th Oct 12", "$132,000"],
["Brenden", "Wagner", "Software Engineer", "San Francisco", "7th Jun 11", "$206,850"],
["Brielle", "Williamson", "Integration Specialist", "New York", "2nd Dec 12", "$372,000"]
]
}
I need to append relevant data set to the tbody
according to the select option changing value.
Is anyone have any experience regarding this to solve this out..?

It shows that message because it's trying to initialize a datatable when there's already one for that table.
You could set an option to the initalization to destroy the datatable if it already exists (docs):
function loadedData(sId) {
var table = $('#example').DataTable({
"processing": true,
"serverSide": true,
"ajax": {
"url": "ajaxdata.json",
"type": "POST"
},
"sScrollY": "300px",
"scrollX":true,
"paging": false,
"bFilter": false,
"bInfo": false,
"searching": false,
"bSort" : false,
"fixedColumns": true,
"destroy": true
});
}
But in my opinion, if you are able to, it is better to work with the datatables api and change the ajax source. You can use a parameter like @Cerlin Boss' answer, or if you want to change the url datatables has a ajax.url()
method (docs). Suposing you have initialized your table elsewhere and saved it in a table
variable:
$('select#exampleSelect').on('change', function() {
var sId = $(this).children(":selected").attr('id');
table.ajax.url( 'newData.json' ).load();
});

Instead of trying to reinitializing the datatable, you can always send a parameter with your ajax request and force the datatable to refresh the data on demand
So your datatable initializing code will look something similar to the below code.
var table = $('#example').DataTable({
"processing": true,
"serverSide": true,
"ajax": {
"url": "ajaxdata.json",
"type": "POST",
"data": function ( d ) {
d.filtervalue = $(this).children(":selected").attr('id'); // Ofcourse you can change this parametername as you want or add more parameters.
}
},
"sScrollY": "300px",
"scrollX":true,
"paging": false,
"bFilter": false,
"bInfo": false,
"searching": false,
"bSort" : false,
"fixedColumns": true
});
Your select change event will look something like below.
$('select#exampleSelect').on('change', function() {
// Make sure that `table` variable is available inside your change method
table.ajax.reload();
});
