I have a function in ajax where I get data in the success

function editarUsuario(id_usu) {
    alert(id_usu);

        $.ajax({  
            url: "EditServlet",
            type: "GET",
            data: {
                id:id_usu
            },
            success: function (info_usu) {
                alert(info_usu);
            },
            error: function () {
                alert("no trae datos");
            }
        });
}

I put an alert to show info_usu

How do I get the name only? I hope you can help me.

My Joomla website does not run the index.php and instead of displaying the content of the site when accessing the domain, download the index.php file I'm getting: Data column (s) for axis # 0 can not be of type string

first you should know what kind of data you have in info_usu, it seems that it is an array, but to make sure you can do it by putting in the alert typeof (info_usu).

If it's an array, you just have to put the index that interests you in the alert.

alert(info_usu[1])

If it were a string, since the data is separated by ',' you could convert it into an array:

let datos = info_usu.split(',') alert(datos[1])

and then refer to the array element as I said above.
