Why do I have no return in Ajax? It goes through Alert(on top of for), but never enters FOR. I’m not using any framework.
Servlet:
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
recuperarValores(request, response);
} catch (Exception ex) {
Logger.getLogger(GetValores.class.getName()).log(Level.SEVERE, null, ex);
}
}
private void recuperarValores(final HttpServletRequest request, final HttpServletResponse response)
throws IOException, Exception {
request.setCharacterEncoding("UTF-8");
//response.setCharacterEncoding("UTF-8");
response.setContentType("application/json");
PrintWriter out = response.getWriter();
JSONArray jsonArray = new JSONArray();
JSONObject responseObj = new JSONObject();
try{
Escala_DAO e = new Escala_DAO();
List<Escala> procedimentos = e.GetEscalaFunc(12998, "2018-01-01", "2018-01-03");
//JSONArray jsonArray = new JSONArray();
for (Escala obj : procedimentos) {
JSONObject js = new JSONObject();
js.put("jsRe", obj.getRe());
js.put("jsEntra",obj.getEntrada());
js.put("jsSai", obj.getSaida());
System.out.println("**********"+obj.getSaida());//aqui imprime normal
jsonArray.put(js);
}
responseObj.put("jsonArray", jsonArray);
out.print(responseObj);
//out.print(responseObj.toString());
//pw.print(responseObj.toString());
//out.flush();
} catch (JSONException e) {
}
}

}
});
alert("em cima do for");
for(var i=0;i<queryObjectLen;i++){
var inicio = +new Date(queryObject.jsonArray[i].jsEntra);
var fim = +new Date(queryObject.jsonArray[i].jsSai);
var content = "Jovani";
alert("DENTRO DO FOR !!!!!!!!!!!!!!!");
//data.push([inicio,fim,"teste"]);
}
Perfect! It worked, thank you very much!! I thought that there in the "Val" already placed all objects inside the "queryObject". Thank you very much for the help!
