如何使用jquery提醒下面的JSON代码？

Question

我有这个json。我正在使用Google提供的反向地理编码API。我在给定的网址中点击了获取请求，这是我得到的响应。

{
"results": [
    {
        "address_components": [
            {
                "long_name": "Goth Haji Umed Ali Gabole-Konker Road",
                "short_name": "Goth Haji Umed Ali Gabole-Konker Rd",
                "types": [
                    "route"
                ]
            },
            {
                "long_name": "Haji Umaid Ali Goth",
                "short_name": "Haji Umaid Ali Goth",
                "types": [
                    "political",
                    "sublocality",
                    "sublocality_level_2"
                ]
            },
            {
                "long_name": "Gadap",
                "short_name": "Gadap",
                "types": [
                    "political",
                    "sublocality",
                    "sublocality_level_1"
                ]
            },
            {
                "long_name": "Karachi",
                "short_name": "Karachi",
                "types": [
                    "locality",
                    "political"
                ]
            },
                ],    "status": "OK"}

这是我的代码

function successFunction(position) {
        var lat = position.coords.latitude;
        var lng = position.coords.longitude;
        var url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=" + lat + "," + lng + "&key=AIzaSyBcV_CkYu5VvJb1ZZF8GWCAmyzhedGpYzk";
        jQuery.get(url, function (result)
        {
            console.log(result);
        }
        );
    }

JSON在我的控制台中 。 我想提醒城市名称“卡拉奇”。我怎么能得到这个？

试试这个：

＆＃13;

var jsonObj = {
	"results": [{
		"address_components": [{
				"long_name": "Goth Haji Umed Ali Gabole-Konker Road",
				"short_name": "Goth Haji Umed Ali Gabole-Konker Rd",
				"types": [
					"route"
				]
			},
			{
				"long_name": "Haji Umaid Ali Goth",
				"short_name": "Haji Umaid Ali Goth",
				"types": [
					"political",
					"sublocality",
					"sublocality_level_2"
				]
			},
			{
				"long_name": "Gadap",
				"short_name": "Gadap",
				"types": [
					"political",
					"sublocality",
					"sublocality_level_1"
				]
			},
			{
				"long_name": "Karachi",
				"short_name": "Karachi",
				"types": [
					"locality",
					"political"
				]
			}
		],
		"status": "OK"
	}]
};

var res = jsonObj.results[0].address_components.filter(obj => obj.long_name == 'Karachi');

console.log(res[0].long_name);
