angularjs - 在 angularjs 中使用引导模式时没有数据绑定(bind)

Question

我正在使用 mongodb、express、angularjs 和 nodejs 开发一个简单的应用程序。但是我遇到一个问题，当我使用引导模式编辑记录时，数据未与 ng-repeat 中的数据绑定(bind)。

下面是我的代码

entryController.js

function entryController($scope, $modal, entryFactory) {


// Get All Entry
entryFactory.getEntries().success(function(data) {
  $scope.entries = data;
});


// View Entry Detail
$scope.editEntry = function(id){
  var id = id._id;

  var modalInstance = $modal.open({
    templateUrl: 'editEntryModal',
    controller: editEntryModalController,
    resolve: {
        entry: function(){
            return entryFactory.getEntry(id);
        }
    }
  });
};

};

var editEntryModalController = function($scope, $modalInstance, $window, data, entryFactory)  {
$scope.entry = {};


$scope.entry = data.data.entry;
$scope.entry.name = data.data.entry.name;


$scope.editEntry = function(){
    entryFactory.updateEntry(data.data.entry._id, $scope.entry).success(function(){

        $modalInstance.close();
    });
};

$scope.cancel = function(){
    $modalInstance.dismiss('cancel');
}
};

下面是我的html代码(entry.html)

<div class="container-fluid">
  <div class="row">

    <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main">

Answer 1

当您这样做时，您正在检索不同的对象

return entryFactory.getEntry(id);

并绑定(bind)到模式。

鉴于您的列表绑定(bind)到具有不同引用的集合

entryFactory.getEntries().success(function(data) {
  $scope.entries = data;
})

此处的选项是在通过调用 getEntries 完成更新时重新获取实体在 $modalInstance.close(); 之后

其次是更新对象并将其添加到集合中以替换旧对象。
