如何读取本地JSON文件

I am following a tutorial on YouTube but I couldn't make it run. Basically I have a country.json file.and I am trying to retrieve data inside it. What is wrong here??

This is how country.json file looks like

{
  "name": "Germany",
  "capital": "Berlin",
  "pop": "some value"
}

JavaScript

var container = $("div.container");
$("input#get").click(function () {
  $.ajax({
    type: "Get",
    url: "country.json",
    dataType: "json",
    successs: function (data) {
      $.each(data, function (index, item) {
        $.each(item, function (key, value) {
          container.append(key + " : " + value + "</br>");
        });
        container.appendChild("<br/><br>")
      });
    }
  });
});

HTML

<div class="container"></div>
<div id="form-area">
  <h2>Get</h2>
  <input type="submit" id="get" value="get">
</div>

    You can get it like this:-

    <head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>

</head>
<body>
<div class="container"></div>
<div id="form-area">
    <h2>Get</h2>
    <input type="submit" id="get" value="get">
</div>
</body>
</html>

 <script type="text/javascript">
var container = $(".container"); //check change here
$("#get").click(function () { //check change here
    $.getJSON( "country.json", function( data ) {
       var myhtml = ''; // create an empty variable
        $.each(data, function (key, value) {
            myhtml += key + ' : ' + value + '</br>'; // append data to variable

        });
      container.append( myhtml); // append the whole data (variable) to div
    });
});
</script>

    Output (on my local browser):- http://prntscr.com/cq2jjt

    Note:- to read data from json file $.getJSON() is required.
