All response data returns undefined in Ajax call

Question

The Ajax call returns the following JSON:

Everything seems good. But when I try to access any of that content, it returns undefined.

success: function (respuesta){
   alert(respuesta.datos[0].cod_registro);
}

Even attributes like status or success return undefined. Any idea why that is? I'm not sure what I can post to help you.

respuesta.datos[0] is an object. So you have to loop. Something like respuesta.datos[0][0] — Linga, Oct 11 '21 at 16:14
respuesta.datos is an array of arrays of objects, so you'd need respuesta.datos[0][0] to access the first object. The duplicate goes into detail how to iterate over such a structure — Kevin B, Oct 11 '21 at 16:32
You're right. I can't believe that was the problem all along. — xdan, Oct 11 '21 at 16:37

respuesta.datos is an array of objects, so the syntax to access one of them should be something like respuesta.datos[0].cod_registro.

Ah, you're right. Dumb of me. I just edited the question, but essentially, that returns undefined too. – xdan Oct 11 '21 at 16:11
What does `console.log(respuesta.datos[0])` show? – kmoser Oct 11 '21 at 16:12
