Ok so i have a jquery datatable which is structured like this
$(document).ready(function () {
var table = $('#tableContent').DataTable({
"processing": true,
"serverSide": true,
"filter": true,
"ajax": {
"url": "path/to/api",
"type": "POST",
"datatype": "json"
},
"columnDefs": [{
"searchable": false,
"orderable": false,
"targets": 0
}],
"columns": [
null,
{ "data": "data1", "name": "data1", "autoWidth": true },
{ "data": "data2", "name": "data2", "autoWidth": true },
{ "data": "data3", "name": "data3", "autoWidth": true },
{ "data": "data4", "name": "data4", "autoWidth": true },
{ "data": "data5", "name": "data5", "autoWidth": true },
{ "data": "data6", "name": "data6", "autoWidth": true },
{ "data": "data7", "name": "data7", "autoWidth": true }
],
"order": [[1, 'asc']]
});
table.on('order.dt search.dt page.dt', function () {
table.column(0, { search: 'applied', order: 'applied' }).nodes().each(function (cell, i) {
cell.innerHTML = i + 1;
});
}).draw();
});
<table class="tableWrapper" id="tableContent">
<thead>
<tr>
<th>#</th>
<th>data1</th>
<th>data2</th>
<th>data3</th>
<th>data4</th>
<th>data5</th>
<th>data6</th>
<th>data7</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
</tfoot>
</table>
Here is the JSON response to the Api being called
{
"draw":"1",
"recordsFiltered":48,
"recordsTotal":48,
"data":[
{
"data1":"XXXX",
"data2":"XXXX",
"data3":"XXXX",
"data4":"XXXX",
"data5":"XXXX",
"data6":"XXXX",
"data7":"XXXX"
}...
]
}
It throws this error :
"DataTables warning: table id=tableContent - Requested unknown parameter '0' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4" (Attached error message picture)
BUT! shortly after the error is thrown, the data loads in with no issues.
Replacing null with {data:null} seems to get rid of the error but it messes with my index column. What was supposed to be a sequence of 1,2,3,4... is now just a bunch of [object Object]

There is more than one way to get what you want. Here is one way, which uses the internal DataTables index assigned to each row. This assignment is purely sequential: the first row added to the table (from the first data object in your JSON) is index 0 - and so on:
"columnDefs": [ {
"targets": 0,
"render": function ( data, type, row, meta ) {
return meta.row + 1;
}
} ]
You already have a targets: 0 in your sample, so adding in this should be straightforward.
The assigned index will stick to the row, when you sort and filter.
If you want an index which represents where the row is, visually, in the table - that is more complicated (and wouldn't be do-able using server-provided data, of course).

Trying to pass some parameters in JQuery Datatables, its working fine on init.
But when I try to refresh the datatable the values are received as empty on controller side.
Here is the code:
$("#SearchResultsTable").DataTable({
"processing": true,
"serverSide": true,
"bLengthChange": false,
"filter": false,
"pageLength": #Model.PageSize,
"orderMulti": false,
"ajax": {
"url": "/Request/SearchRequest",
"type": "POST",
"datatype": "json",
"data": {
"Date_To": document.getElementById("Date_To").value,
"Date_From": document.getElementById("Date_From").value
}
},
"columns": [
{ "data": "ABC", "name": "ABC", "autoWidth": true },
{ "data": "DEF", "name": "DEF", "autoWidth": true }
]
});
Refresh Datatable:
$("#Search_Btn").click(function () {
$("#SearchResultsTable").DataTable().clear();
$("#SearchResultsTable").DataTable().draw();
});
Also tried:
$("#Search_Btn").click(function () {
var table = $('#SearchResultsTable').DataTable();
table.ajax.reload();
});
I would like to refresh the table in such a way the updated vales of 'Date_To' & 'Date_From' are available on controller side.
You will need to pass the parameters via jquery datatable like below:
"data": function (data) {
data.Date_To = document.getElementById("Date_To").value;
data.Date_From = document.getElementById("Date_From").value;
}
Please take a look at the following tutorial for more details
https://www.codeproject.com/Articles/1170086/Grid-with-Server-Side-Advanced-Search-using-JQuery
I have this datatables declaration:
table = $("#table").DataTable({
"ajax": {
"url": '#Url.Action("Search", #ViewContext.RouteData.Values["controller"].ToString())',
"type": "POST",
"data": function(d) {},
"datatype": "json"
},
"language": {
"search": "",
"searchPlaceholder": " Search"
},
"select": {
"style": 'multi'
},
"ordering": true,
"lengthChange": false,
"columns": [{
"data": "",
"targets": 0,
"className": "control",
"orderable": false,
"searchable": false
}, {
"data": function(data, type, row, meta) {
var url = '#Url.Action("Read", #ViewContext.RouteData.Values["controller"].ToString())/' + data.Id;
return "<a href='" + url + "'>" + data.Application + "</i></a>"
},
"name": "Application"
}, {
"data": "Logged",
"name": "Logged",
"render": function(data) {
var d = moment(data).format("YYYY-MM-DD hh:mm:ss");
return d;
}
}, {
"data": "Level",
"name": "Level"
}, {
"data": "Exception",
"name": "Exception"
}, {
"data": "Message",
"name": "Message"
}, {
"data": "UserName",
"name": "UserName"
}, {
"data": "ServerName",
"name": "ServerName"
}, ],
"responsive": {
"details": {
"type": "column"
}
},
"processing": true,
"serverSide": true,
}).columns.adjust().responsive.recalc();
new $.fn.dataTable.FixedHeader(table);
This is my table header declaration:
<thead>
<tr>
<th></th>
<th>Application</th>
<th>Logged</th>
<th>Level</th>
<th>Exception</th>
<th>Message</th>
<th>UserName</th>
<th>ServerName</th>
</tr>
</thead>
The idea is that the first column or target 0 should be where a button sits to expand or collapse the row. However, when I run the application, I get this error
DataTables warning: table id=table - Requested unknown parameter '' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4
Its saying that my column 0 parameter can't be blank. But I am unsure of what I should put inside it.
Also, for some reason the sorting arrow is still appearing for that column even though its disabled. However, the arrow doesn't change or do anything when clicked.
You have 8 columns, but only have data for 7 of them. Because you're using server-side processing and have no data for that row, you need to add "defaultContent": "" to your column option like so:
"columns": [{
"data": "",
"targets": 0,
"className": "control",
"orderable": false,
"searchable": false,
"defaultContent": ""
},
The same can be achived with "data": null but you'll most likely get an [object Object] returned if you don't deal with the null value before it renders.
I have used server-side processing data table.
Here is my datatable configuration:
var table = $("#job-table").DataTable({
"ajax": {
"url": "<?php echo url('/getJobs');?>",
"type": "POST",
"data": function (d) {
d.connection = connectionArray,
d.company = companyArray,
d.type = typeArray
}
},
"processing": true,
"serverSide": true,
"columns": [
{ "data": "id" },
{ "data": "job_id" },
{ "data": "type" },
{ "data": "connection_id" },
{ "data": "company_id" },
{ "data": "message" },
{ "data": "total_completion_time" },
{ "data": "date" },
{ "data": "start_time" },
{ "data": "end_time" },
{ "data": "error_time" }
],
"info": false,
"searching": false,
"bLengthChange": false
});
In this datatable ajax response I have passed some another data which I am gonna use to set custom label value.
Right now, I am using same ajax call to set label value. There are two calls one is of datatable and another call for setting label. Both time I am calling same API. but want to know how can I avoid second ajax call?
Is there any way to use data-table ajax call response to set custom label value?
I do something similar. I used the dataFilter callback to handle it.
so given HTML:
<input id="txtOne"/>
<input id="txtTwo"/>
<table id="job-table" class="display"></table>
Serverside code is returning a JSON Serialized object that looks like:
{ ValueOne: "some data",
ValueTwo: "Some more data",
data: [array of data for the table] }
My table definition looks like (notice the dataFilter section):
var table = $("#job-table").DataTable({
"ajax": {
"url": "<?php echo url('/getJobs');?>",
"type": "POST",
"data": function (d) {
d.connection = connectionArray,
d.company = companyArray,
d.type = typeArray
},
// I added this section. It is called before the success callback
// You will have to figure out your parsing at this point because
// each configuration is different so I just put how mine is.
dataFilter: function(response){
var temp = JSON.parse(response);
$("#txtOne").val(temp.ValueOne);
$("#txtTwo").val(temp.ValueTwo);
return response;
}
},
"processing": true,
"serverSide": true,
"columns": [
{ "data": "id" },
{ "data": "job_id" },
{ "data": "type" },
{ "data": "connection_id" },
{ "data": "company_id" },
{ "data": "message" },
{ "data": "total_completion_time" },
{ "data": "date" },
{ "data": "start_time" },
{ "data": "end_time" },
{ "data": "error_time" }
],
"info": false,
"searching": false,
"bLengthChange": false
});
When loading a jQuery DataTable, I have the code shown below. How do I pass additional parameters to the AJAX call? The fnServerParams callback suggested in the questions and answers below does not work. That is, naively using aodata.push() results in "push is undefined" (because, indeed, aodata is not an array). So what's the correct way to do this?

"data": "value",
"mRender": function (data) {
return htmlEncode(IoTApp.Helpers.Numbers.localizeFromInvariant(data));

},
],
"columnDefs": [
{
"targets": [0, 1, 2, 3],
"className": 'table_alertHistory_issueType',
"width": "20%"
}
],
});
I neglected to RTFM. The fnServerParams callback is now legacy for versions 1.9 and earlier. In the latest version of DataTables, you leverage the ajax data parameter as described in the DataTables documentation. In the example below, appending mykey to the d object will do the trick:
$(document).ready(function() {
$('#example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
"url": "scripts/server_processing.php",
"data": function ( d ) {
d.myKey = "myValue";
// d.custom = $('#myInput').val();
// etc
}
}
} );
} );
I would like to output a bootstrap label for one value of a field in a JQuery dataTable. This fields possible values can be '0' or '1' and depending on the result I want to decide which bootstrap label I want to output in the dataTable. Unfortunately I don't know how I can do this if statement for this case.
My JQuery:
$(document).ready(function() {
$('#accountOverview').dataTable( {
"ajax": {
"url": "/database/accounts.php",
"data": {"action": "selectAccounts"},
"dataSrc": ""
},
"columns": [
{ "data": "email" },
{ "data": "platform" },
{ "data": "coins" },
{ "data": "profitDay" },
{ "data": "playerName" },
{ "data": "tradepileCards" },
{ "data": "tradepileValue" },
{ "data": "enabled" }
],
"autoWidth": false
});
});
I need to use something like this for the result of the "enabled" field:
if(enabled==1) <label class="label label-success">Online</label>
else <label class="label label-error">Offline</label>
HTML Table:
<table id="accountOverview" class="table datatable">
<thead>
<tr>
<th>E-Mail</th>
<th>Platform</th>
<th>Coins</th>
<th>Profit last 24h</th>
<th>Playername</th>
<th>Tradepile Cards</th>
<th>Tradepile Value</th>
<th>Status</th>
</tr>
</thead>
<tbody id="accountList">
<!-- List all accounts -->
</tbody>
</table>
The label needs to be in the field "status" = the last each row.
Following dataTable's "draw" (which happens after AJAX loads your data), you can look up the last td of each row and use wrapInner() to inject the HTML you want. So, in your case, try:
var apply_label=function(){
$('#accountOverview').find('td:last-child').not(':has(.label)').each(function(){
if( this.innerHTML==="1"){
$(this).wrapInner('<span class="label label-success"></span>');
}
else {
$(this).wrapInner('<span class="label label-danger"></span>');
}
});
};
$('#accountOverview').dataTable( {
"ajax": {
"url": "/database/accounts.php",
"data": {"action": "selectAccounts"},
"dataSrc": ""
},
"columns": [
{ "data": "email" },
{ "data": "platform" },
{ "data": "coins" },
{ "data": "profitDay" },
{ "data": "playerName" },
{ "data": "tradepileCards" },
{ "data": "tradepileValue" },
{ "data": "enabled" }
],
"autoWidth": false,
"drawCallback": function( settings ) {
apply_label();
}
});
Notes:
I think you want span (not label).
I think you want .label-danger (not .label-error).
