I get this return with json_encode by php but I am not able to read it in ajax Success, what I am doing wrong?

{"id":"1","id_pesquisa":"3","id_pergunta":"7","id_resposta":"31","mostrar":"1","ocultar":"2"},
{"id":"2","id_pesquisa":"3","id_pergunta":"8","id_resposta":"31","mostrar":"2","ocultar":"1"}

var direcao = $.ajax({
  type : 'get',
  url: 'dadosPS.php?ps=direcionamento',
  dataType: 'JSON',
  beforeSend: function (xhr) {

  },success: function (data, textStatus, jqXHR) {
    for(var i = 0;i<data.length;i++){
      console.log(data[i].id);
    }
  },error: function (jqXHR, textStatus, errorThrown) {

  }
});

  • what error it shows you on the console ?

  • Retorna este erro :Uncaught TypeError: Cannot use 'in' operator to search for '185' in {"id":"1","id_pesquisa":"3","id_pergunta":"7","id_resposta":"31","mostrar":"1","ocultar":"2"}{"id":"2","id_pesquisa":"3","id_pergunta":"8","id_resposta":"31","mostrar":"2","ocultar":"1"}

  • True, if there are any errors json might not show correctly, check this line 185 and analyze this word in

  • If this is JSON.. it is WRONG! Use jsonlint to validate your JSON.

  • In addition to fixing your php file, it also tries to use javascript dataType: 'json', JSON for json (lower case)

  • Well I made the corrections but nothing to work, as William said must be wrong this JSON. @Williamasimiliar, which would be the correct format to read?

  • Install the Postman and paste this url there to see or that happens the glue in your browser itself and see what returns

  • @Carloslopes In this case, must be in square brackets.

Try to return only the data on success and inside you make it:

...
   /* resto do codigo */
    success: function (data) {
       $.each(data, function(i, j)){
         console.log( j.id );
        }
     }

...

At least it works that way with me

I don’t think you’re using the variable direction so I removed it, you can always remove functions other than yours, like this:

$.ajax({
  type : 'GET',
  url: 'dadosPS.php?ps=direcionamento',
  dataType: 'JSON',
  success: function (data) {
     var data = JSON.parse(data);
     $.each(data, function(i, v)){
         console.log( v.id );
     }
  }
});

  • When I use dataType:JSON, there is no error, but nothing appears on the console...

  • edited the answer. try so

  • remains the same, no console appears anything. I think this json return must be wrong.

  • is most likely

Here is the solution: Adjusted json to -> {"data":[{"id":"1","id_pesquisa":"3","id_pergunta":"7","id_resposta":"31","mostrar":"1","ocultar":"2"},{"id":"2","id_pesquisa":"3","id_pergunta":"8","id_resposta":"31","mostrar":"2","ocultar":"1"}]}

//Direcionamnetos
       $.ajax({
            type : 'GET',
            url: 'dadosPS.php?ps=direcionamento',
            dataType: 'json',
            success: function (data) {

               $.each(data.data, function(key, val){
                  console.log(val.id);
              });

            }
          });

Thank you all for your suggestions !!!!

  • would not necessarily need to return the date in php, but how nice that it worked.
