Ensure that you correctly execute a JSON method

Can you assist with correctly calling the loadlist function using this JSON data below?

I have attempted to call it as shown but it appears to not be functioning properly:

loadlist($('select#selName').get(0), 'pull.php','data.name')

This is the JSON data in question:

{
  data: [
    {
      id: "e0b0d8sc5ffd82e",
      name: "John",
    }
  ]
}

Below is the implementation of the function:

function loadlist(selobj,url,nameattr) {
  $(selobj).empty();
  $.getJSON(url,{},function(data)
  {
    $(selobj).append(
        $('<option>Select</option>')
                    .val('null')
    );

    $.each(data, function(i,obj)
    {
        $(selobj).append(
             $('<option></option>')
                    .val(obj[nameattr])
                    .html(obj[nameattr]));
    });
  });
}

Answer №1

Your assertion that accessing obj["data.name"] is the same as obj.data.name is inaccurate. (The correct equivalent involves two property accesses: obj["data"]["name"])

If you anticipate needing to retrieve nested properties, consider using a function for property retrieval. (This approach also accommodates dynamically computed values.)

function loadlist(selobj,url,getter) {
  $(selobj).empty();
  $.getJSON(url,{},function(data)
  {
    $(selobj).append(
        $('<option>Select</option>')
                    .val('null')
    );

    $.each(data, function(i,obj)
    {
        var value = getter(obj);
        $(selobj).append(
             $('<option></option>')
                    .val(value)
                    .html(value));
    });
  });
}

// Example of calling the function:
loadlist($('select#selName').get(0), 'pull.php', function (obj) {
    return obj.data.name;
});
