Question

我目前正在更新我的网站以使用我的新API，但是我一直坚持在每个循环中访问嵌套对象。我不知道该如何描述它了，因为我是整个ajax json类型的东西的新手。也许，如果您查看我的API输出和我想出的JS，您将会明白我的意思。

这是我的代码，实际上没有用...

$.ajax({
    url: "https://api.reyfm.de/v3/channel-sequence",
    dataType: 'json',
    success: function(data) {
        rfm.log('Erfolgreich geladen.');
        $.each(data, function(key, value) {
            //COVER
            rfm.log('Coverart CHN' + key + ': ' + value);;
            $("#channel-" + key + " .cover").attr("src", (value));
        });
    },
    error: function() {
        log('Ein Fehler ist aufgetreten: API nicht verfügbar.');
    }
});

这是我要从以下位置加载数据的API：https://api.reyfm.de/v3/channel-sequence

Answer 1

您的循环是错误的。更改为：

.each(data, function(key, value) {

收件人：

$.each(data.channels, function(key, value) {

另一个错误是选择器中的空格：

$("#channel-" + key + " .cover")
                       ^

无论如何，当您按ID选择时，不需要任何其他属性。足够了：

$("#channel-" + key)

您的最后一个问题是如何访问元素网址：

value.coverurl

代替：

(value)

您的循环现在是：

$.each(data.channels, function(key, value) {
    $("#channel-" + key).attr("src", value.coverurl);
});

var data = {
    "all-listeners": "235",
