Question

我发送了一个带有javascript的GET请求并解析了结果＆＃xA; var result = JSON.parse（response）; ＆＃xA;然后定义变量“title”＆＃xA; var title = result.title; ＆＃xA;接下来我尝试将变量加载到id =“fishplanet-title”＆＃xA的标记中;但是HTML给出了一个错误，说“标题”没有定义。＆＃xA; document.getElementById（“fishplanet-title”）。innerHTML = title; ＆＃xA;我知道请求正在通过，因为我已将其登录到控制台。

Answer 1

result.title无效。 title属性位于数组中，因此您需要对其进行迭代以获取title值：

{
    "appnews": {
        "appid": 380600,
        "newsitems": [
            {
                "gid": "2175660043472720797",
                "title": "QuestionsAnswers",
                "url": "http://store.steampowered.com/news/externalpost/steam_community_announcements/2175660043472720797",
                "is_external_url": true,
                "author": "Olcha",
                "contents": "1.\"What is the garage icon for at the bottom of the Inventory page? Will this be for boat access and when can we expect boats to be launched?\" That’s right - the Garage will soon be the place from where you can access Boats.

                "feedlabel": "Community Announcements",
                "date": 1506799022,
                "feedname": "steam_community_announcements",
                "feed_type": 1,
                "appid": 380600
            }
        ]
        ,
        "count": 277
    }
}

要访问title属性，您需要执行以下操作：

var title = JSON.parse(result).appnews.newsitems[0].title;

由于newsitems是一个数组，如果返回多个数组，则需要进行一些迭代。
