Pass Parameters through ajax call - ajax url

I am trying to pass value parameter through the ajax call to the controller. It is a date value. I am struggling to find a way to pass parameters through this ajax url. Please help.
function dataTable() {
var value = $("#somedatevalue).val();
$("#thisTable").DataTable({
"processing": true,
"paging": false,
"language": {
processing: "<span class='processing-message'><i class='fa fa-circle-o-notch fa-spin'></i> Processing...</span>"
},
ajax: {
url: $('table#thisTable').data("ajaxurl"),
type: "POST",
datatype: "json",
},
"columns": [
{
"data": "column1",
},
{
"data": "column2",
},
{
"data": "column3",
},
{
"data": "column4",
},
{
"data": "column5",
},
{
"data": "Url",
"render": function (data) {
return '<a class="btn btn-info" href="' + data + '">Select</a>';
}
}
],
"dom": 't<"col-lg-3"l><"col-lg-6"p><"col-lg-3"i>'
});
}

You can pass value as query parameter like http://www.url.com?date="17-02-21"
If you are using php use can get the value as $_GET['date']
If you are using node js, you can get value as req.query.date

Consider the following.
function dataTable() {
$("#thisTable").DataTable({
"processing": true,
"paging": false,
"language": {
processing: "<span class='processing-message'><i class='fa fa-circle-o-notch fa-spin'></i> Processing...</span>"
},
"ajax": {
"url": $('table#thisTable').data("ajaxurl"),
"type": "POST",
"data": { "someDate": $("#somedatevalue").val() },
"datatype": "json"
},
"columns": [
{
"data": "column1",
},
{
"data": "column2",
},
{
"data": "column3",
},
{
"data": "column4",
},
{
"data": "column5",
},
{
"data": "Url",
"render": function (data) {
return '<a class="btn btn-info" href="' + data + '">Select</a>';
}
}
],
"dom": 't<"col-lg-3"l><"col-lg-6"p><"col-lg-3"i>'
});
}
First you must address the Typo in your jQuery Selector. Then you can adjust your Ajax parameters to include a data.
See more here: https://datatables.net/reference/option/ajax.data
In principle it operates in exactly the same way as jQuery's $.ajax.data property, in that it can be given as an object with parameters and values to submit, but DataTables extends this by also providing it with the ability to be a function, to allow the data to be re-evaluated upon each Ajax request (see above).

JQuery Datatable initialization

I'm getting this error while trying to supply JSON into my DataTable:
DataTables warning: table id=myTable - Requested unknown parameter 'a' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4
This is what my JSON looks like:
[{
"a": "asdsaddas",
"b": "asdasda",
"c": "0000000001",
"d": "name"
}]
When user clicks button I'm generating and showing the table with an AJAX callback:
$('#find_button').click(function() {
event.preventDefault();
if (validateAll()) {
$("#myTable").DataTable({
"lengthChange": false,
"pageLength": 20,
autoWidth: false,
serverSide: true,
processing: true,
"dataSrc": "",
"ajax": function(data, callback, settings) {
var $form = $("#my_form_id");
var jsonData = getFormData($form, data.start, data.length);
var request = $.ajax({
type: "POST",
url: "api",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(jsonData),
dataType: "json"
});
request.then(function(response) {
console.log(JSON.stringify(response.data));
callback({
data: [JSON.stringify(response.data)],
recordsTotal: response.total,
recordsFiltered: response.total
})
}, failCallback);
},
columns: [{
"data": "a"
}, {
"data": "b"
}, {
"data": "c"
}, {
"data": "d"
}],
filter: false,
info: false,
ordering: false
});
$('#htmlTable').show();
}
});
I've read a lot of related questions with same bug, but still cannot make it work in my case. Maybe there is problem that DataTable is initialized before it gets response from server?

Is it possible to use Ajax success result to populate jQuery DataTable

I would like to declare my jQuery datatable without initially populating it and later when calling Ajax functions, I would like to take the results and use that as the data source for my data table, right now I am making multiple Ajax calls for the same purpose and I would like to eliminate this if possible.
$.ajax({
type: "GET",
url: "/Receiving/GetUnorderedParts",
datatype: "html",
data: { "id": button.attr("data-ponumber") },
success: function(data) {
var orderButton = $(".js-Order");
orderButton.removeClass("invisible");
tbl = $("#UnorderedDetail")
.DataTable({
"destroy": true,
"searching": false,
"ordering": false,
"lengthChange": false,
"pagingType": "full_numbers",
"paging": true,
"lengthMenu": [10, 25, 50, 75, 100],
ajax: {
url: "/Receiving/GetUnorderedParts",
data: { "id": button.attr("data-ponumber") },
datasrc: ""
},
"columnDefs": [
{
targets: -1,
className: 'dt-body-center'
}
],
columns: [
{
data: "Description"
},
{
data: "VendorPartNumber"
},
{
data: "Quantity"
},
{
data: "CartID",
render: function(data) {
return "<button class='btn btn-danger js-delete' data-cart-id=" +
data +
">Delete</button>";
}
}
] //EOColumns
}); //EODataTable
} //EOSuccess
}); //EOInnerAjax

You can call a function to build the data table on success something like:
$.ajax({
type: "GET",
url: "/Receiving/GetUnorderedParts",
datatype: "html",
data: { "id": button.attr("data-ponumber") },
success: function(data) {
var orderButton = $(".js-Order");
orderButton.removeClass("invisible");
createTable(data);
}
});
and the function can take in the array of objects and create a data table:
function createTable(dataSet)
{
$('#example').DataTable({
data: dataSet,
"aoColumns": [{
"sTitle": "Description",
"mData": "Description"
}, {
"sTitle": "VendorPartNumber",
"mData": "VendorPartNumber"
}, {
"sTitle": "Quantity",
"mData": "Quantity"
}, {
"sTitle": "CartID",
"mData": "CartID",
"mRender": function(data) {
return "<button class='btn btn-danger js-delete' data-cart- id=" + data + ">Delete</button>";
}}]
});
}
Check out a working example . It takes in an array of objects and create a datatable.

JQuery Datatables not load immediately/disable autolaod

I am using JQuery Datatables 1.10.15 I would like to search first before loading the data because i have 300,000+ rows, maybe something like
if (table not loaded) {
(load the table)
}
else {
(Search)
}
or any other ways, please help me
this is my code:
var mytable = $('#myDatatable').DataTable({
"ajax": {
"url": '/Home/GetAllRecords',
"type": "POST",
"datatype": "json",
"data": (records)
},
"columns": [
{ "data": "id", "autoWidth": true },
{ "data": "name", "autoWidth": true }
]
});
$('#btnSearch').on("click", function () {
mytable.ajax.reload();
});

How to send form data along with jQuery DataTables data in server-side processing mode

I am trying to post form data without success and data couldn't be loaded.
How can I pass all form data with array and single textbox, combobox, etc. to fnServerdata?
table_obj = $('#group-table').dataTable({
"sAjaxSource": "URL Goes here",
fnServerData: function(sSource, aoData, fnCallback,oSettings) {
oSettings.jqXHR = $.ajax( {
"dataType": 'json',
"type": "POST",
"url": sSource+'?'+$.param(aoData),
"data": $("#frm").serializeArray(),
"success": fnCallback
} );
},
aaSorting: [[ 1, "desc" ]],
bProcessing: true,
bServerSide: true,
processing : true,
columnDefs: [{
'targets': 0,
'searchable':false,
'orderable':false,
'className': 'dt-body-center',
'render': function (data, type, full, meta){
return '<label><input type="checkbox" name="user_id[]" value="' + $('<div/>').text(data).html() + '"></label>';
}
}],
rowCallback: function(row, data, dataIndex){
// If row ID is in list of selected row IDs
if($.inArray(data[0], rows_selected) !== -1){
$(row).find('input[type="checkbox"]').prop('checked', true);
$(row).addClass('selected');
}
},
iDisplayLength: '50',
});

If you want to format the POST data, you can also format the form data using jquery .each() function. Let me use the answer above using solution #1 but with jquery .each() to format the data.
$('table').DataTable({
"ajax": {
"url": "URL HERE",
"type": "POST",
"data": function(d) {
var frm_data = $('form').serializeArray();
$.each(frm_data, function(key, val) {
d[val.name] = val.value;
});
}
}
});
Then you can just access that in PHP like:
var $data = $_POST['name'];

SOLUTION 1
Replace this:
$('#group-table').dataTable({
"sAjaxSource": "URL Goes here",
fnServerData: function(sSource, aoData, fnCallback,oSettings) {
oSettings.jqXHR = $.ajax( {
"dataType": 'json',
"type": "POST",
"url": sSource+'?'+$.param(aoData),
"data": $("#frm").serializeArray(),
"success": fnCallback
} );
},
with:
$('#group-table').dataTable({
"ajax": {
"url": "URL Goes here",
"type": "POST",
"data": function(d){
d.form = $("#frm").serializeArray();
}
},
Your form data will be in form parameter as an array of objects with parameters name and value, below is JSON representation:
"form": [{"name":"param1","value":"val1"},{"name":"param2","value":"val2"}]
SOLUTION 2
If you want to have form data as name/value pairs, see this jsFiddle for an example of alternative solution.
NOTES
There are checkboxes in your data table. Solution above will not work for form elements in the data table, because DataTable removes non-visible nodes from DOM.

How about this?
$('#group-table').DataTable( {
"processing": true,
"serverSide": true,
"bDestroy": true,
"bJQueryUI": true,
"ajax": {
"url": "url here",
"type": "POST",
"data": {
store: $('#store').val(),
month: $('#m').val(),
year: $('#y').val(),
status: $('#status').val(),
},
}
} );
then you can access the sample data above through PHP using this.
$_POST['store']
$_POST['month']
$_POST['year']
$_POST['status]
Hope that helps.
