How to call controller method with array - ajax

Question

Controller import() Import data from csv file and redirect with array of data
//import data from csv file
return redirect('school/student/import')->with('result', $result);
import.blade.php
This is a modal form and imported data is shown to user.
#if(Session::has('result'))
#php
$result = Session::get('result');
#endphp
<table class="table table-hover">
<thead>
...
<tr>
#foreach($result as $datarow)
<tr>
<td>{{$datarow['student_no']}}</th>
....
</tr>
#endforeach
</tbody>
</table>
#endif
<button type="submit" class="btn btn-primary">Save changes</button>
#section('js')
<script>
#if(Session::has('result'))
//$result = IS IT POSSIBLE TO ACCESS $result;
$('#exampleModalCenter').modal('show');
$("form#myForm").submit(function(event) {
event.preventDefault();
$('#exampleModalCenter').modal('hide');
$.ajax({
type: "POST",
url: "savedata",
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: **$result**,
success: function(data){
window.location = '{{ url("school/student") }}';
},
});
});
#endif
</script>
#stop
Once submit is clicked, I want to call Controller savedata() with $result data array.
I tried with both form submit and ajax post but the issue is since $result is an array, it's difficult to pass. Also unable to access session values from JavaScript.

Need to provide the route name
routes/web.php
Route::post('savedata', 'ExampleController#savedata')->name('example.savedata');
After naming the route, you need to provide the route name to the URL for ajax.
$("form#myForm").submit(function(event) {
event.preventDefault();
$('#exampleModalCenter').modal('hide');
$.ajax({
type: "POST",
url: '{{route("example.savedata")}}',
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: $result,
success: function(data){
window.location = '{{ url("school/student") }}';
},
});
});
