Question

我有以下JS和HTML：

$scope.loadInstallation = function (installationid) {
    $scope.currentInstallation = {};
    $scope.currentInstallation = $scope.installationList[installationid];;
    $scope.currentInstallationID = installationid;
};

<div class="row">
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList1">Module 1:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList1" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList2">Module 2:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList2" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList3">Module 3:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList3" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList4">Module 4:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList4" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList5">Module 5:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList5" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label for="installationmoduleIdList6">Module 6:</label>
            <div class="form-control">
                <label><input type="checkbox" id="installationmoduleIdList6" ng-model="currentInstallation.moduleIdList" /></label>
            </div>
        </div>
    </div>
</div>

一个JSON，看起来像这样：

currentInstallation =
{
  "id":"1",
  "moduleIdList": [ "1", "2" ]
}

“moduleIdList”中的“1”在HTML“Module 1：”复选框中等于“true”，问题是，我不知道，如何将“moduleIdList”绑定到Checkboxes，这样当在“moduleIdList”中有一个“1”，检查复选框，当有人取消选中它时，“1”将从数组中删除

希望你能理解我的问题，我很高兴有任何帮助！

问候，西蒙

好的，我有一个解决方法，这对我来说没问题。我只是不使用ng-model，而是使用ng-checked ng-click，所以我可以使用函数，这将完全符合我的要求：

＆＃13;

$scope.loadInstallation = function (installationid) {
    $scope.currentInstallation = {};
    $scope.currentInstallation = $scope.installationList[installationid];;
    $scope.currentInstallationID = installationid;
};

$scope.isModuleSelected = function (id) {
    if ($scope.currentInstallation.moduleIdList != null && $scope.currentInstallation.moduleIdList.indexOf(id) != -1)
        return true;
    else
        return false;
};

$scope.toggleModule = function (id) {
    if ($scope.currentInstallation.moduleIdList == null)
           $scope.currentInstallation.moduleIdList = [];
    var numberOnIndex = $scope.currentInstallation.moduleIdList.indexOf(id);
    if (numberOnIndex == -1)
        $scope.currentInstallation.moduleIdList.push(id);
    else 
        $scope.currentInstallation.moduleIdList.splice(numberOnIndex, 1);
};
