Using ajax to update the currently page with Laravel - ajax

Question

I have this ajax inside my file.php (It hits the success callback):
<script type="text/javascript">
$('#selectSemestres').change(function(obj){
var anoSemestre = $(this).val();
$.ajax({
type: 'GET',
url: '{{ route('professor') }}',
data: {anoSemestre: anoSemestre},
success: function(data){
console.log(data);
}
});
})
</script>
Now on my Controller:
public function getProfessorList()
{
$professor = Professor::all();
$ano_semestre = isset($_GET['anoSemestre']) ? $_GET['anoSemestre'] : Horario::first()->distinct()->pluck('ano_semestre');
$semestres = Horario::distinct()->select('ano_semestre')->get()->toArray();
return View::make('professor', compact('professor', 'semestres', 'ano_semestre'));
}
What I want to do:
I have a LIST with professor and their disciplines. What I need to do is:
Whenever I change the value of that select box, I just remake the function with the new parameter.
I'm trying to use ajax to remake that list but nothing change, not even the URL with the professor.php?anoSemestre=xx.
Also, when I try to use the $_GET['anoSemestre'] the page doesnt show any change or any ECHO.
But If I go to Chrome spector>NEtwork and click the ajax I just made, it shows me the page with the data I sent.
Cant find out what I'm doing wrong.
UPDATE
I did what was suggested me, now I'm working with the data I get from the success callback:
<script type="text/javascript">
$('#selectSemestres').change(function(obj){
var anoSemestre = $(this).val();
$.ajax({
type: 'GET',
url: '{{ route('professor') }}',
data: {anoSemestre: anoSemestre},
success: function(data){
var lista = $(data).find('#list-professores'); //Get only the new professor list and thier disciplines
$('#list-professores').remove(); //Remove old list
$('#professores').append(lista); //Append the new list where the old list was before.
}
});
})
</script>
The return of var lista = $(data).find('#list-professores'); is:
Accordion Effect
#list-professores li input[name='item']:checked ~ .prof-disciplinas {
height: auto;
display:block;
min-height:40px;
max-height:400px;
}
This list is an Accordion Menu (using a checkbox and changing it with js&css), so everytime I click on a professor < li>, it's suppose to open and show a sublist (disciplines of that professor I clicked). But it's not opening anymore and no errors on the console. No idea why.

The issue here is what you are returning in your controller and how you do it, you don´t need to redirect or refresh the entire page. This could be achived using a single blade partial for the piece of code you may want/need to update over ajax. Assuming you have an exlusive view for that info, you could solve this with something like this:
in your view:
<div class="tableInfo">
<!--Here goes all data you may want to refresh/rebuild-->
</div>
In your javascript:
<script type="text/javascript">
$('#selectSemestres').change(function(obj){
var anoSemestre = $(this).val();
$.ajax({
type: 'GET',
url: '{{ route('professor') }}',
data: {anoSemestre: anoSemestre},
success: function(){
$('.tableInfo').html(data); //---------> look at here!
}
});
})
</script>
in your controller:
public function getProfessorList()
{
$professor = Professor::all();
$ano_semestre = isset($_GET['anoSemestre']) ? $_GET['anoSemestre'] : Horario::first()->distinct()->pluck('ano_semestre');
$semestres = Horario::distinct()->select('ano_semestre')->get()->toArray();
if (Request::ajax()) {
return response()->json(view('YourExclusiveDataPartialViewHere', ['with' => $SomeDataHereIfNeeded])->render()); //---------> This is the single partial which contains the updated info!
}else{
return View::make('professor', compact('professor', 'semestres', 'ano_semestre'));//---------> This view should include the partial for the initial state! (first load of the page);
}
}
