我的JSON就在这里......我想只有CITIES - 而不是剩余的CITIES,只有选项值里面的城市名称,然后我要插入到表单中。 但是我的脚本正在返回所有内容。我错过了什么吗?
代码在这里:
<script>
$(function () {
var shops = new Array();
var show_options = '';
$.getJSON('shops.json', function(data) {
for (var i = 0; i < data.cities.length; i++) {
console.log('<option value="'+data.cities[i]+'>'+data.cities[i]+'</option>');
}
});
});
</script>
我正在进口的JSON文件

}]
}

请注意,data.cities是一个包含一个对象的数组,其键是城市名称,因此您需要迭代这些键:
$.getJSON('shops.json', function(data) {
Object.keys(data.cities[0]).forEach(function (city) {
console.log('<option value="' + city + '">' + city + '</option>');
});
});
