Ajax Data Call with or without slash in Codeigniter getting error

suppose my URL is example.com/controller/method/
when I use this ajax code it makes URL like example.com/controller/method/method which not getting data.
function getProductList() {
var category = document.getElementById('Category').value;
$.ajax({
type: 'POST',
url: 'GetProductList',
data: {CategoryId: category},
dataType: 'json',
cache:false,
success: function (response) {
}
});
}
but when my URL is example.com/controller/method then ajax getting data correctly. but i want to get data from the database on both situations.

Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method. So you can not use example.com/controller/method/method.The segments in a URI normally follow this pattern: example.com/class/function/id/ , So your last method argument treated as a id. so create method in controller with the default argument Ex. public function mymethod($method = ''){ /** Your logic goes here */ }

Transfer to another page in AJAX call

Hi there is it possible to redirect to another page using ajax? I have this piece of code that I have been working on to try this.
<script type="text/javascript">
$(document.body).on('click', '#btnPrintPrev', function() {
$.ajax({
url: '/pdfdatacal',
data: {
dummydata: "This is a dummy data"
},
});
});
</script>
Now it should be able to carry data to another page and redirect there. Problem is it doesn't.
This is what I am using in my route
Route::get('/pdfdatacal', 'GenerateReportController#pdfdatacal');
Then in the controller
public function pdfdatacal(Request $request) {
return $request->data['dummydata'];
}
My expected result should be a blank page containing the value of dummydata but it doesn't do that in my code. How do I accomplish this?

first your ajax must be something like
$.ajax({
url: '/pdfdatacal',
method: 'post',
data: { dummydata: "This is a dummy data" },
dataType: "JSON",
success: function(response){
console.log(response); // just to check if the data is being passed
// do something you want if ever .
}
});
then in your routes
Route::post('/pdfdatacal', 'GenerateReportController#pdfdatacal');
in your controller
public function pdfdatacal(Request $request) {
return response()->json($request->dummydata);
}
hope it helps ..

Use
window.location.href = "http://yourwebsite.com/pdfdatacal";
In your success call
The idea is that you send data to your controller, it sends back a response, then you redirect from javascript to where you want.
$.ajax({
url: '/pdfdatacal',
type : 'GET',
data : {
dummydata: "This is a dummy data"
},
success : function(data) {
window.location.href = "http://yourwebsite.com/pdfdatacal";
}
});
But if your controller does nothing with the data you send, then you don't need to use ajax at all, simple redirect using javascript.

you could use window.location.assign('your URL here!'); in the success.
success : function(data) {
window.location.assign('your URL here!');
}

Sending a JSON object to Django backend through AJAX call

I have the following code (jQuery) to create a json file:
$( ".save" ).on("click", function(){
var items=[];
$("tr.data").each(function() {
var item = {
item.Code : $(this).find('td:nth-child(1) span').html(),
itemQuantity : $(this).find('td:nth-child(4) span').html()
};
items.push(item);
});
});
Now this is my AJAX function:
(function() {
$.ajax({
url : "",
type: "POST",
data:{ //I need my items object, how do I send it to backend server (django)??
calltype:'save'},
dataType: "application/json", // datatype being sent
success : function(jsondata) {
//do something
},
error : function() {
//do something
}
});
}());
Now, my doubt is how do I send the 'item[]' object that I created to the backend? I do need to send both the item[] object and the variable 'calltype' which signals what made the AJAX call, as I have the same Django View (its the Controller equivalent for Django) in the backend being called by different AJAX functions.
How will my AJAX function look like?

Hey guys just got my answer right.
I used the following ajax function to get it right:
(function() {
$.ajax({
url : "",
type: "POST",
data:{ bill_details: items,
calltype: 'save',
'csrfmiddlewaretoken': csrf_token},
dataType: 'json',
// handle a successful response
success : function(jsondata) {
console.log(jsondata); // log the returned json to the console
alert(jsondata['name']);
},
// handle a non-successful response
error : function() {
console.log("Error"); // provide a bit more info about the error to the console
}
});
}());
So, this is sort of a self answer!!! :) Thanks a lot SO!!

Calling a C# method from JavaScript

I want to to call a method GetAccount from my controller AccountController.cs, in my JavaScript factory LoginFactory.js. Something like this:
AccountController.cs:
public Account GetAccount(string userName)
{ ... }
LoginFactory.js:
if(x>y) {
var account = <%AccountController.GetAccount(someParam);%>
}
I've tried using [WebMethod] and Ajax, but I can't get it to work: I get a 404 response.

Assuming your GetAccount method can be reached at /Account/GetAccount when your application runs, you could use the following:
$.ajax({
type: 'GET',
url: '/Account/GetAccount',
data: { 'username' : 'a-username' },
dataType: 'json',
success: function(jsonData) {
alert(jsonData);
},
error: function() {
alert('error');
}
});
Note - this is dependant on jQuery.
This causes the browser to make a request to /Account/GetAccount as if you had done so by entering the URL in the URL bar, but of course, captures the returned json for use in your client side (javascript) script.
If this returns a 404, it would be worth checking your routing.

Call ASP.NET C# Controller Method from Javascript

I have a var toto in a javascript file. And I want to call a C# Controller Method who return a string and of course assign the resulted string to toto.
I tried some ways to achieve this but nothing seems to work.
Somebody can explain me the simpliest way to achieve that ? It's a Windows Azure project.
Many Thanks !

You could use AJAX. For example with jQuery you could use the $.getJSON method to send an AJAX request top a controller action that returns a JSON encoded result and inside the success callback use the results:
$.getJSON('/home/someaction', function(result) {
var toto = result.SomeValue;
alert(toto);
});
and the controller action:
public ActionResult SomeAction()
{
return Json(new { SomeValue = "foo bar" }, JsonRequestBehavior.AllowGet);
}

You have to use JSON:
Controler
public class PersonController : Controller
{
[HttpPost]
public JsonResult Create(Person person)
{
return Json(person); //dummy example, just serialize back the received Person object
}
}
Javascript
$.ajax({
type: "POST",
url: "/person/create",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: jsonData,
success: function (result){
console.log(result); //log to the console to see whether it worked
},
error: function (error){
alert("There was an error posting the data to the server: " + error.responseText);
}
});
