javascript - 美国城市/州数组的简单方法

Question

所以我有这个网络应用程序，它在 JavaScript 中使用这个位置选择变量。我想知道是否有一种简单的方法可以为美国进行转换/执行此操作，而无需输入每个州和城市。

  var location_selectors = {"country":["Australia"],"state":{"Australia":["Australian Capital Territory","New South Wales","Northern Territory","Queensland","South Australia","Tasmania","Victoria","Western Australia"]},"city":{"Australian Capital Territory":["Canberra"],"New South Wales":["Sydney","Albury","Armidale","Bathurst","Broken Hill","Cessnock","Coffs Harbour","Dubbo","Gosford","Goulburn","Grafton","Griffith","Lake Macquarie","Lismore","Maitland","Newcastle","Nowra","Orange","Port Macquarie","Queanbeyan","Tamworth","Tweed Heads","Wagga Wagga","Wollongong","Wyong"],"Northern Territory":["Darwin","Alice Springs","Katherine","Palmerston"],"Queensland":["Brisbane","Bundaberg","Cairns","Charters Towers","Gladstone","Gold Coast","Gympie","Hervey Bay","Ipswich","Logan City","Mackay","Maryborough","Mount Isa","Nambour","Redcliffe","Rockhampton","Sunshine Coast","Thuringowa","Toowoomba","Townsville"],"South Australia":["Adelaide","Mount Gambier","Murray Bridge","Port Augusta","Port Pirie","Port Lincoln","Victor Harbor","Whyalla"],"Tasmania":["Hobart","Burnie","Clarence","Devonport","Glenorchy","Launceston"],"Victoria":["Melbourne","Benalla","Ballarat","Bendigo","Geelong","Latrobe City","Mildura","Shepparton","Swan     Hill","Wangaratta","Warrnambool","Wodonga"],"Western Australia":    ["Perth","Albany","Broome","Bunbury","Geraldton","Fremantle","Kalgoorlie","Mandu    rah","Port Hedland"]}};

这是 php 版本

快速搜索得到了这个:

第一个应该适合基本使用。但不要认为它有状态。在这种情况下可能需要使用第二个 API
