显示YouTube JSON中的数据

Question

我想显示：

＆＃34; subscriberCount＆＃34;：＆＃34; 42＆＃34;，来自thson json文档。

$.getJSON( "https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCgTe4gCl_pH-RNkgdcndl8g&key=AIzaSyARe-kxioXcvyS-WE3mx6Bo2fAijyG4OWo", function( data ) {
  var items = [];
  $.each( data, function( key, val ) {
    items.push( "<li id='" + key + "'>" + val + "</li>" );
  });

  $( "<ul/>", {
    "class": "my-new-list",
    html: items.join( "" )
  }).appendTo( "body" );
});

如何在文档中访问subscriberCount级别？

JSON数据如下所示：
