I have a system running normally in Laravel 5.2, but I need resources that only have the most current versions of the framework. With this I updated it to version 5.6 and I am having problems with ajax requests that previously works normally in Aravel 5.2.
Updated script with tips from contributors who answered this question .
<script>
jQuery("form.form").submit(function () {
var dados = jQuery(this).serialize();
$.ajax({
type:'POST',
url: jQuery("form.form").attr("action"),
data: dados,
success:function(data){
alert('Sucesso');
},
error:function(jqxhr, textStatus, err){
console.log(err);
},
});
return false;
});
</script>
controller
public function Buscar()
{
//caso eu retorno apenas uma string como abaixo, funciona normalmente e caí no
//método success
return 'teste';
//caso eu retorno um array json que é o que preciso ele caí no método
//error com a seguinte mensagem SyntaxError: Unexpected token
//in JSON at position 0
//at parse (<anonymous>)
return response()->json(['pagina'=>'teste','result'=>'1']);
}
Note: In both cases when monitoring in the browser console the data is returned right in the 'network tab'
Conclusion, if I return a string works normal, but if an array returns it enters the error with the message Syntaxerror: Unexpected token in JSON at position 0 parsat() in the console, but still it gives the return of data in the network tab.
Already tried to define a dataType:"json" ??

If when tracking through the console the data is coming, the problem would not be at the time of manipulating this data?

When you return Return Response()->json(['page'=>'test','result'=>'1']); it appears in the console in the network tab?
– Wictor Chaves
yes, it appears correctly in the network tab, but falls in the script error method, I have also tested dataType:"json" .

I’d rather identify the mistake if you did:
error:function(jqxhr, textStatus, err){ console.log(err); },– Valdeir Psr
Valdeir, following his tip got the most detailed error, now I have this return Syntaxerror: Unexpected token in JSON at position 0 at parse (<Anonymous>) , then I tried to add the token in the returning array: Return Response()->json(['token'=>$token,'pagina'=>$p,'result'=>'1']); this $token variable is the value of the _token field that is created by the Laravel , picked it correctly in the controller and added it in the array at the position promiera, but even adding the token it continues to give the error

Try this in the header <meta name="csrf-token" content="{{ csrf_token() }}" /> And this in the script <script type="text/javascript"> $. ajaxSetup({ headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') } }); </script>

tried this tip,keeps giving the error Syntaxerror: Unexpected token in JSON at position 0 at parse , literally translating it as an unexpected Token in JSON at position 0
