如何使用ng-repeat从数组中的对象显示特定属性。电子邮件字段是我想要显示的内容

JSON：

[
    {
        "TypeId": 3,
        "Type": "Listings",
        "emails": [
            "someemail2@example.com", 
            "someemail3@example.com", 
            "someemail5@example.com"
        ]
    }
]

控制器：

myService.getEmails().then(function (emails) {
    if (emails && emails.length) {
        $scope.emailsList = emails
    }
})

HTML：

<tr ng-repeat="item in emailsList['emails'] track by $index">
    <td>
        <div class="rounded-checkbox">
            <input class="form-check-input" type="checkbox">
            <span></span>
        </div>
    </td>
    <td class="col-xs-12">{{ item }}</td>
    <td>-</td>
</tr>

Answer 1

假设$scope.emailsList是电子邮件数组，请更改您的HTML

<tr ng-repeat="item in emailsList[0].emails track by $index">
    <td>
        <div class="rounded-checkbox">
            <input class="form-check-input" type="checkbox">
            <span></span>
        </div>
    </td>
    <td class="col-xs-12">{{ item }}</td>
    <td>-</td>
</tr>
