The office proyect revisited. Calling the function callback in the get method when is not anonymus??

Hello. I am trying to make this proyect by declaring separately;

var url =" var url = "../data/employees json";" and var callback =function(response){}

and then call them both in the $.getJOSN( url, callback);

How can I declare this properly? Here is my code so far. Not a single touch in the HTML and the widget.js file is linked

$(document).ready(function(){ $.getJSON(url, callback()); // set the path to JSON file var url = "../data/employees json";
// declare callback function var callback= function(response){
var statusHTML ='<ul class="bulleted">'; // <ITERACION EACH $.each(response, function(index,employee){ //$.each(data, function(index, value){}); if(employee.inoffice===true){ statusHTML += '<li class="in">'; }else{ statusHTML += '<li class="out">'; } statusHTML += employee.name + '</li>'; }); statusHTML+= '</ul>';
$('#employeeList').html(statusHTML);
}

});

And by the way..can anyone help me with the format on posts?? dont now who to make my code looks like in text editors when posting questions.. Thanks!!

Formatting instructions are in the the Markdown Cheatsheet pop-up link below. :arrow_heading_down:
Remember to skip a blank line before the code block.

You don't want to do this:

  $.getJSON(url, callback()); // set the path to JSON file

That invokes the callback function instead of passing it. Instead do this (notice no parentheses):

  $.getJSON(url, callback); // set the path to JSON file

Also, I think you substituted a space where there should be a period on this line:

  var url = "../data/employees.json";  // <-- note: period added
