Handlebars.js通過變量訪問嵌套數組值

Question

我有一個嵌套的對象，所有索引都是時間戳，它包含有關時間戳日期和當天事件的信息

data : {
    1522620000:  {
        events: {
           1522620940: {title: event1},
           1522620970: {title: event2},
        }
    },
    1522706400:
        events: {
           1522620940: {title: event4},
           1522620970: {title: event6},
        }
    },
    1523311200: {
        events: {}
    },
    ...
}

如何在不循環訪問數組的情況下訪問星期五的所有事件？ 我只有時間戳1522706400表示為可變timestamp ，我data[timestamp].events一樣訪問它

目前我有

{{#each day}} //<-- another variable from a calendar.. don't care about it
    {{# each data[timestamp].events }} //<-- the day contains information about the timestamp but does not contain the events..
        {{ title }}
    {{/each}}
{{/each}}

我通常使用AngularJS來完成類似的工作，但是我有一個客戶端希望我改用車把，對此我感到很困惑。

Answer 1

我自己就能解決。 我創建了以下Helper

Handlebars.registerHelper("getNestedValue", function(obj, options) {
    var context,
        response = "";
    var timestamp = options.hash.key;

    if(typeof obj[timestamp] !== 'undefined'){
        var data = obj[timestamp]; // <-- all information for the timestamp
        $.each(data.events, function (index, item) { // <-- loop through all events
            context = item;
            response += options.fn(context); // <-- include the variable to the template
        });

    }

    return response;
});

所以我可以像訪問它

{{#getNestedValue  ../data key=timestamp }}
    <li class="icon-calendar-events-16">
        <a href="{{ url }}">
            {{ title }}
        </a>
        <small>{{ location }}</small>
    </li>
{{/getNestedValue}}
