AJAX return JSON size

I am having doubts about using AJAX, I am making a function to build a list according to some filters.

Everything is working perfectly, I return the JSON and I mount the table. The problem is when my return contains a lot of data.

It seems that I have not received the entire data package yet, and AJAX already enters success:

So the table is assembled in half.

I have tried to use callbacks, .done () ... Nothing solved this problem for me.

Follow my code ...

$.ajax({
        url: 'php/ficha_cadastral_function.php',
        data:{ action: 'pesquisaCliente'
             , cnpj: cnpj
             , razaoSocial: razaoSocial
             , telefone: telefone
             , nomeFantasia: nomeFantasia
             , email: email
             , representante: representante
             , iniScore: iniScore
             , fimScore: fimScore
             , situacao: situacao },
        dataType: 'JSON',
        type: 'POST',
        async: false,
        success: function(DATA){
            if(DATA.STATUS == 200){
                tabela += ' <form method="post" action="ficha_cliente.php"> ';
                tabela += ' <hr/> ' +
                              ' <div class="col-xs-12" id="lista_cliente"> ' +
                                  ' <table class="table table-bordered small" > ' +
                                      ' <thead> ' +

                $('#listaCliente').html(tabela);
            }
        },
        error: function(DATA) {
            alerta('Ocorreu um erro ao carregar o cliente! (ERRO - fncPesquisaCliente)', 'danger');
            limpaLista();
        }
    });

Would anyone have a hint of how I could solve this?

I do not believe that you did not receive the entire package once a response request exits the backend server, ajax only returns status 200 when all the header and content is returned to the browser. What happens to your code is that some of the variables that come with json must contain a value with an inverted comma or quotation mark that is breaking the concatenation of its variable table.

How you can resolve:

First take the real test! Remove all variables DATA.DATA [$ i] from your html within your routine, run the code, if it works go by inserting one by one. Until you find out which one has some invalid character, responsible for breaking the syntax of your javascript. Once you have that information, you just have to validate the output backend correctly.

<tr>' + 
'<td class="text-center" id="tdCNPJ">'DATA.DADOS[$i].CNPJ_TITULO + '</td>' + 
'<td class="text-center" id="tdRazaoSocial"></td>' + 
'<td class="text-center" id="tdNomeFantasia"></td>' + 
'<td class="text-center" id="tdTelefone">''</td>' + 
'<td class="text-center" id="tdEmail"></td>' + 
'<td class="text-center" id="tdRepresentante"></td>' + 
'<td class="text-center" id="tdScore"></td>' + 
'<td class="text-center" id="tdSituacao"></td>' + 
'<td class="text-center" id="tdAcao">' ;

I hope this information is helpful
