I need to create a variable "name" which represents values in the Name column and use the variable in a hyperlink, generated in a subsequent column (ID).
var table1 = $("#table1").DataTable({
"ajax": {
"url": "www.qwe.com",
"dataSrc": "info"
},
"columns": [
{ "data": "name", "width": "45%"},
{ data : "id",
"title": "ID",
"width": "45%",
"render": function (data, type, row, meta) {
return '' + data + '';}},
{ "data": "value", "width": "10%" }]
});
Your code looks generally OK. There is already a column ("data":"name") present.
I think you need row.name instead of name in your concatenation.

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]
see image
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).
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
});
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)
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).
