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
});

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 am using Datatable to render a table. The code is -
var nextPage;
$(document).ready(function() {
$('#table').DataTable( {
"processing": true,
"ordering": false,
"serverSide": true,
"sorting":false,
"paging": true,
"pageLength":20,
"lengthChange" :false,
"pagingType":"simple",
"ajax": function (data, callback, settings) {
data.nextPage=document.getElementById("nextPage").value
$.ajax({url: "get/list", data: data, success: function(result){
document.getElementById("nextPage").value=result.nextPage;
callback(result);
}});
},
"columns": [
{ "data": "first_name" },
{ "data": "title" },
{ "data": "first_name" },
{ "data": "first_name" },
{ "data": "first_name" },
{ "data": "first_name" },
{ "data": "work_email" }
]
});
});
The first page loads fine when I open the page, but the second page keeps on loading. The /get/list API call succeeds for the second page but the data is not rendered on the browser and loading icon keeps on rotating.
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?

"autoWidth": false,
"bSort": false,
"displayStart": 0,
"paging": false,
"lengthChange": false,
"processing": true,

},
],
"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 can successfully fill my datatable with ajax call, but then I don't know how to parse JSON that is received by datatable with this ajax call.
Here is my JavaScript code, that makes ajax call to the server and fills my datatable correctly:
$('#transactions').DataTable({
"processing": true,
"ajax": {
"url": "/transactions
},
"columns": [
{ "data": "car"},
{ "data": "card_number"},
{ "data": "invoice"},
{ "data": "status"}
]
});
This is the JSON object returned from the server:
{
"data": [
{
"car": 190,
"card_number": "6395637",
"invoice": 200,
"status": "success"
},
{
"car": 191,
"card_number": "9473650",
"invoice": 180,
"status": "success"
}
],
"balance": 7300
}
As you can see, the data parameter of the returned JSON object is used by the datatables function to fill by datatables, and now I want to parse the balance parameter, but I can't. How can i achieve this?
Something like this:
$('#transactions').dataTable({
"ajax" : {
"url" : "/transactions",
"dataSrc" : function (json) {
// manipulate your data (json)
...
// return the data that DataTables is to use to draw the table
return json.data;
}
}
});
Docs: https://datatables.net/reference/option/ajax.dataSrc
Don't use the url feature of DataTable, make the Ajax call yourself
$.getJSON('/transactions', function(response) {
$('#transactions').dataTable({
processing: true,
data: response.data,
columns: [
{ data: "car"},
{ data: "card_number"},
{ data: "invoice"},
{ data: "status"}
]
});
window.someGlobalOrWhatever = response.balance
});
Since DataTables 1.10, you may use the ajax.json() function: https://datatables.net/reference/api/ajax.json()
I have implemented it in the example code below.
$( document ).ready(function() {
$('#search-form').submit(function(e) {
e.preventDefault();
var table = $('#location-table').DataTable({
destroy: true,
ajax: "/locations.json",
columns: [
{ "data": "code" },
{ "data": "status" },
{ "data": "name" },
{ "data": "region" },
{ "data": "address" },
{ "data": "city" },
{ "data": "state" },
{ "data": "zip" },
{ "data": "phone_number" },
]
})
table.on( 'xhr', function () {
var json = table.ajax.json();
$('#totals').text(json.totals)
});
})
});
NOTE for this to work you must initialize the datatable with $('#location-table').DataTable() and not $('#location-table').dataTable (the difference being the capitalized D)
