In the View how to send a data in javascript to the controller

I have a datatable and I want, when I click some row I get row id and go back to the controller and uptade some data by the row id. I am getting row id(data.SiparisID) BUT I cant send data to controller`#section scripts{
<script>
$(document).ready(function () {
});
$("#SiparisTable").DataTable({
"ajax": {
"url": "/Goster/getList",
"type": "GET",
"datatype": "json"
},
"columns": [
{ "data": "SiparisID" },
{ "data": "SiparisAd" },
{ "data": "SiparisModel" },
{ "data": "SiparisTur" },
{ "data": "SiparisAdet" },
{ "data": "SiparisTarih" },
{ "data": "SiparisDurum" },
{
"data": "SiparisID", "render": function () {
return "<input type='submit' value='Güncelle' class='btn btn-default' onclick='backoperation()' />"
}
}
]
});
var table = $('#SiparisTable').DataTable();
$('#SiparisTable tbody').on('click', 'tr', function () {
var data = table.row(this).data();
alert('You clicked on ' + data.SiparisID + '\'s row');
});
</script>
<script>
function backoperation() {
window.location.href = "#Url.Action("Index", "Guncelle")";
}
</script>
}
`

function backoperation() {
window.location.href = "#Url.Action("Index", "Guncelle")?param=obj";
}
this case it redirect to another page
or
you can make request through Ajax request
"ajax": {
"url": "/Goster/getList??param=obj",
"type": "GET",
"datatype": "json"
},
then it come in your controller
this case it updated in same view

var table = $('#SiparisTable').DataTable();
$('#SiparisTable tbody').on('click', 'tr', function () {
var data = table.row(this).data();
alert('You clicked on ' + data.SiparisID + '\'s row');
$.ajax({
url: '/Guncelle/Process',
type: 'GET',
data: {
id: data.SiparisID,
success: function () { },
error: function () { }
}
});
});**THE VIEW**
public ActionResult Process(int id)THE CONTROLLER
{}
I found this and this work for me. I can get the id in the script with this controller

How to Update Datatable automatically after dialog box is closed in Javascript

Here I have two JS files in which one is main JS file for parent page which contains Datatable which gets populated through ajax call. And other one is specifically for update functionality in which function is defined to update required values into database. That update is done in dialog box. So after successful update sweet alert comes which shows product is successfully updated. So what I want is updated values should be immediately reflected in Datatable of Parent Page. Currently it is showing old value only untill I refresh my page manually. Below are both JS files. And I am new in Javascript and Jquery. So Please help

There are a few way you could handle this.
One way you could handle this is to store the item/s in a variable in a jSON array.
When get confirmation back from the server that that the the update was successful you could then create function to update the dataTable with with this function.
function updateDataTable(dataTableObj,jsonArray)
/*
Clears and populates the dataTable with JSON array
*/
dataTableObj.clear();
jsonArray.forEach(function(row){
dataTableObj.row.add(row);
});
dataTableObj.draw();
}
The other way you could update the table is to create a route on your server that sends the jsonArray but this requires an additional request to the server.
Note: If you use the Ajax call be sure to invoke the function inside the the ajax callback function

How to fix data table initialization error?

I have written one function that makes one ajax call and gets the data and creates a table.I calling this function again and again.But while doing that I am getting reinitialization of table error.Can someone please help me to fix the issue.
Function :
function getLibraryFilesStudent() {
var reqBody = {
"uploader": Cookies.get('user')
};
$.ajax({
url: '../library/libraryfilegetlist',
data: JSON.stringify(reqBody),
dataType: 'json',
headers: {
"Content-Type": "application/json",

},
error: function(data) {
console.log(data);
},
success: function(data) {
if (data.length) {
var trHTML = [];
for (var i = 0; i < data.length; i++) {
var test = '<input type="radio" class="radio" name="selectFile" value=' + data[i].id + "," + data[i].keyword + ",flag=1" + '>';
trArr = [data[i].name, data[i].keyword, test]
trHTML.push(trArr);
if (data.length == trHTML.length) {
$('#lFileList').DataTable({

},
{
title: "Action"
}
]
});
}
}
}
},
type: 'POST'
});

Tabbing doesnt work for datatable

I m using jquery datatables in many pages and its working good in every page and in a single page its not working properly, i mean when i use tab to go through datatable, it works fine for the first time and when i try to do the same for second time, if i try to focus on any thing in few seconds in data table, the focus disappears and the foucs starts from the starting of the page.
Here goes the code
function tableCall(){
var clientId = $('#clientId').val();
var versionCount = $('#versionCount').val();
var fromDate = $('#fromDate').val();
var toDate = $('#toDate').val();
$.ajax({
url: auditTrail.props.reporttableURL,
type: "POST",
dataType: "json",
data: {
clientId:clientId,
versionCount:versionCount,
fromDate:fromDate,
toDate:toDate
},
success: function (data) {
searchJSON = data.data;
var len=searchJSON.length;
if (len > 0){
$('.no-data, #warning-sign').hide();
createTable();
}else{
$('.no-data').hide();
$('#warning-sign').show();
}
}
});
}
function createTable() {
wwhs.setADAAttrDynamic($('#auditTable'));
if ($.fn.DataTable.isDataTable('#auditTable')) {
// table.destroy();
$("#auditTable tbody").empty();
}
table = $('#auditTable').dataTable({
"searching":false,
"destroy":true,
"autoWidth": false,
"ordering": true,
"destroy":true,
"stateSave": true,
"drawCallback": attachEvents,
"stateLoadParams": function (settings, data) {
return false;
},
data: searchJSON,
columns: [{
data: "reportName"
}, {
data: "reportStatus"
}, {
data: "timeStamp"
}, {
data: "requestedBy"
}],
"columnDefs": [{
"render": function (data, type, row) {
if(row.reportStatus.toUpperCase() == 'PROCESSED')
return '<a class="blue-text" " data-name="'+ row.reportName +'">' + row.reportName + '</a>';
else
return row.reportName;
},
"width": "50%",
"targets": 0
}, {
"width": "15%",
"targets": 1
}, {
"width": "20%",
"targets": 2
}, {
"width": "15%",
"targets": 3
}]
});
}

I think the problem is because the datatable instance is not destroyed.
Since datatables saves all the nodes into an object and renders it when ever it wants, emptying the tbody doesnt do anything. it just removes the elements in the page which can be re-drawn/re-rendered by datatable from its stored object.
You can check if the object is already initialized and the destroy it before re-initializing.
if(typeof table != "undefined")
table.destroy();
So the final code will look something like
function tableCall(){
var clientId = $('#clientId').val();
var versionCount = $('#versionCount').val();
var fromDate = $('#fromDate').val();
var toDate = $('#toDate').val();
$.ajax({
url: auditTrail.props.reporttableURL,
type: "POST",
dataType: "json",
data: {
clientId:clientId,
versionCount:versionCount,
fromDate:fromDate,
toDate:toDate
},
success: function (data) {
searchJSON = data.data;
var len=searchJSON.length;
if (len > 0){
$('.no-data, #warning-sign').hide();
createTable();
} else {
$('.no-data').hide();
$('#warning-sign').show();
}
}
});
}
function createTable() {
wwhs.setADAAttrDynamic($('#auditTable'));
if ($.fn.DataTable.isDataTable('#auditTable')) {
if(typeof table != "undefined")
table.destroy();
}
table = $('#auditTable').dataTable({
"searching":false,
"destroy":true,
"autoWidth": false,
"ordering": true,
"destroy":true,
"stateSave": true,
"drawCallback": attachEvents,
"stateLoadParams": function (settings, data) {
return false;
},
data: searchJSON,
columns: [{
data: "reportName"
}, {
data: "reportStatus"
}, {
data: "timeStamp"
}, {
data: "requestedBy"
}],
"columnDefs": [{
"render": function (data, type, row) {
if(row.reportStatus.toUpperCase() == 'PROCESSED')
return '<a class="blue-text" " data-name="'+ row.reportName +'">' + row.reportName + '</a>';
else
return row.reportName;
},
"width": "50%",
"targets": 0
}, {
"width": "15%",
"targets": 1
}, {
"width": "20%",
"targets": 2
}, {
"width": "15%",
"targets": 3
}]
});
}

Event only fires once when making Ajax request in jQuery

I have a couple of drop downs that are populated from SharePoint using SPServices. This part works great. But then, I have a button that on click loads data from SharePoint and uses the dropdown texts as filter to fetch the data that will populate a table using the DataTables plugin. This part works only once; if I click the button again, nothing happens.
This is how I populate the dropdowns:
$(document).ready(function () {
var theYear; // Selected Year
var theRO; // Selected RO
//Fills the Dropdown lists (Year and RO)
$().SPServices({
operation: "GetListItems",
async: false,
listName: "{ListID}",
CAMLViewFields: "<ViewFields><FieldRef Name='Fiscal_x0020_Year' /><FieldRef Name='Regional_x0020_Office' /></ViewFields>",
completefunc: function (xData, Status) {
//Add Select Value option
$("#dropdown").prepend($('<option>', {
value: '',
text: 'Select Fiscal Year'
}));
$("#dropdownRO").prepend($('<option>', {
value: '',
text: 'Select Regional Office'
}));
//Fetching Data from SharePoint
$(xData.responseXML).SPFilterNode("z:row").each(function () {
var dropDown = "<option value='" + $(this).attr("ows_Fiscal_x0020_Year") + "'>" + $(this).attr("ows_Fiscal_x0020_Year") + "</option>";
var dropDownRO = "<option value='" + $(this).attr("ows_Regional_x0020_Office") + "'>" + $(this).attr("ows_Regional_x0020_Office") + "</option>";
$("#dropdown").append(dropDown);
$("#dropdownRO").append(dropDownRO);
/////////////Deletes duplicates from dropdown list////////////////
var usedNames = {};
$("#dropdown > option, #dropdownRO > option").each(function () {
if (usedNames[this.text]) {
$(this).remove();
} else {
usedNames[this.text] = this.value;
}
});
////Deletes repeated rows from table
var seen = {};
$('#myTable tr, #tasksUL li, .dropdown-menu li').each(function () {
var txt = $(this).text();
if (seen[txt]) $(this).remove();
else seen[txt] = true;
});
});
} //end of completeFunc
}); //end of SPServices
$('.myButton').on('click', function () {
run()
});
}); //End jQuery Function
This is the function I need to run every time I click on "myButton" after changing my selection in the dropdowns:
function run() {
theYear = $('#dropdown option:selected').text(); // Selected Year
theRO = $('#dropdownRO option:selected').text(); // Selected RO
var call = $.ajax({
url: "https://blah-blah-blah/_api/web/lists/getByTitle('Consolidated%20LC%20Report')/items()?$filter=Fiscal_x0020_Year%20eq%20'" + theYear + "' and Regional_x0020_Office eq '" + theRO + "'&$orderby=Id&$select=Id,Title,Fiscal_x0020_Year,Notices_x0020_Received,Declined_x0020_Participation,Selected_x0020_Field_x0020_Revie,Selected_x0020_File_x0020_Review,Pending,Pending_x0020_Previous_x0020_Yea,Controversial,GFP_x0020_Reviews,NAD_x0020_Appeals,Mediation_x0020_Cases,Monthly_x0020_Cost_x0020_Savings,Monthly_x0020_Expenditure,Regional_x0020_Office,Month_Number", //Works, filters added

I'm not a programmer, I'm just trying to learn. I would appreciate any help. Thanks in advance

I would guess that you are replacing the part of the page where the button lives. (you really need to format your code more neatly for SO... use JSFiddle.net and their TidyUp button).
If that is the case you need to use a delegated event handler:
$(document).on('click', '.myButton', function () {
run()
});
This listens at a static ancestor of the desired node, then runs the selector when the event occurs, then it applies the function to any matching elements that caused the event.
document is the fallback parent if you don't have a convenient ancestor. Do not use 'body' for delegated events as it has odd behaviour.
