javascript - $index 不存在于 ng-repeat 中 - 答案在我原来的帖子中

Question

当我尝试将 $index 绑定(bind)到复选框时，在 ng-repeat 中获取 $index 时遇到问题。首先，我分配一个如下所示的数组:

来自 php 的 var_dump:

array(3) {
    [0] => array(9) {
        ["first_name"] => string(3)
        "emp" ["last_name"] => string(5)
        "loyee" ["username"] => string(4)
        "emp1" ["email"] => string(22)
        "blabla@gmail.com" ["id"] => string(3)
        "539" ["rights_type"] => string(1)
        "3" ["editProfile"] => bool(true)["sendMessage"] => bool(true)["editApps"] => bool(false)
    }[1] => array(9) {
        ["first_name"] => string(3)
        "one" ["last_name"] => string(4)
        "more" ["username"] => string(4)
        "emp2" ["email"] => string(19)
        "blabla@gmail.com" ["id"] => string(3)
        "540" ["rights_type"] => string(1)
        "0" ["editProfile"] => bool(false)["sendMessage"] => bool(false)["editApps"] => bool(false)
    }["isEmpty"] => bool(false)
} 

我的代码如下所示:

<tr ng-repeat="employee in employees.result track by $index" ng-if="employee.username">
    <th class="col-md-1" scope="row">{{employee.username}} - ({{employee.first_name}} {{employee.last_name}})</th>
    <td class="col-md-1"><input type="checkbox" ng-model="employees.result.$index.editProfile"></td>
    <td class="col-md-1"><input type="checkbox" ng-model="employees.result.$index.sendMessage"></td>
    <td class="col-md-1"><input type="checkbox" ng-model="employees.result.$index.editApps"></td>
</tr>

该对象正在附加到 Controller 中的 $scope。重要的是， ng-repeat 确实有效，我得到了名字、用户名等的正确值，只是我无法得到 $index 。 当我尝试打印 {{$index}} 时，我什么也没得到。我尝试从数组中删除“isEmpty”键，但它也没有帮助。有什么想法吗？

我所要做的就是将employees.result更改为employee，并且它实际上更新了employees.result(分别是数组的每个单元格)，所以它看起来像:

<tr ng-repeat="employee in employees.result track by $index" ng-if="employee.username">
    <th class="col-md-1" scope="row">{{employee.username}} - ({{employee.first_name}} {{employee.last_name}})</th>
    <td class="col-md-1"><input type="checkbox" ng-model="employee.editProfile"></td>
    <td class="col-md-1"><input type="checkbox" ng-model="employee.sendMessage"></td>
    <td class="col-md-1"><input type="checkbox" ng-model="employee.editApps"></td>
</tr>
