I am trying to fill a HTML Dropdown menu with data from an external JSON file, which contains the following
{
    \"Destinations\": [
    {
        \"destinatio         
        
Try this code :
$.getJSON('yourfile.json', function(data) {
    destinations = data['Destinations']
    $.each(destinations, function(id, destination) {
        destination = destination["destinationName"]
        alert(destination)
    })
});
It allows you to get the destination value in the destination variable, for, after, can do everything with values of this variable.
