Hi again Antonio,
First of all, make sure you are using a good browser with debugging
capabilities (I prefer Chrome), because you'll need it.
Secondly, I usually use the $.ajax request, instead of the post. Mainly
because post is a wrapper around ajax and you can more finely change the
settings of ajax.
So the post in your case would be:
$.ajax({
type: 'POST', // Make sure you post
dataType: 'json', // Use this so that you request json from
the server
url: "/sitioweb/json/",
data: data,
success: function(data) {
// The data that is returned is your json data, already parser, so
you don't have to parse it!
alert(data.array[0]); // Need to write "array" because that is
what you are sending to the browser (your structure looks like that, check
what the server is responding with)
},
error: function(xhr, textStatus, errorThrown) {
console.log('AJAX communication failed:', textStatus, errorThrown);
// In case there is an error (for example a 500)
}
});
Regards,
Andréas
