javascript - Angularjs如何正确显示对象

Question

我无法显示我的位置对象。我正在显示它，但它会抛出整个数组，我有点卡在这部分了。

我的问题是如何删除 [] 括号。

位置json

[
{
    "_id": "5a61acfdd5df1761dd2eb1ef",
    "branch": "Lucena City",
    "__v": 0,
    "building": [
        {
            "name": "mhq",
            "floors": [
                "1st",
                "2nd",
                "3rd"
            ]
        }
    ],
    "dateCreated": "2018-01-19T08:31:57.121Z"
}

]

HTML

<table class="table table-sm">
<thead>
    <tr>
        <th>Branch</th>
        <th>Building</th>
        <th>Floors</th>
    </tr>
</thead>
<tbody>
    <tr ng-repeat="loc in vm.locations">
        <td>{{ loc.branch }}</td>
        <td>{{ loc.building[0].name }}</td>
        <td>
            {{ loc.building[0].floors }}
        </td>
    </tr>
</tbody>
</table>

你可以使用Array#join()

 {{ loc.building[0].floors.join(', ') }}
