Angular UI模式的范围问题

Question

我在理解/使用角度UI模式的范围时遇到麻烦。

尽管这里没有立即显示出来，但我已经正确地设置了模块和所有内容（据我所知），但是这些代码示例尤其是在我发现错误的地方。

index.html（重要部分）

<div class="btn-group">
    <button class="btn dropdown-toggle btn-mini" data-toggle="dropdown">
        Actions
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu pull-right text-left">
        <li><a ng-click="addSimpleGroup()">Add Simple</a></li>
        <li><a ng-click="open()">Add Custom</a></li>
        <li class="divider"></li>
        <li><a ng-click="doBulkDelete()">Remove Selected</a></li>
    </ul>
</div>

Controller.js（同样是重要部分）

MyApp.controller('AppListCtrl', function($scope, $modal){
    $scope.name = 'New Name';
    $scope.groupType = 'New Type';

    $scope.open = function(){
        var modalInstance = $modal.open({
            templateUrl: 'partials/create.html',
            controller: 'AppCreateCtrl'
        });
        modalInstance.result.then(function(response){

            // outputs an object {name: 'Custom Name', groupType: 'Custom Type'}
            // despite the user entering customized values
            console.log('response', response);

            // outputs "New Name", which is fine, makes sense to me.                
            console.log('name', $scope.name);

        });
    };
});

MyApp.controller('AppCreateCtrl', function($scope, $modalInstance){
    $scope.name = 'Custom Name';
    $scope.groupType = 'Custom Type';

    $scope.ok = function(){

        // outputs 'Custom Name' despite user entering "TEST 1"
        console.log('create name', $scope.name);

        // outputs 'Custom Type' despite user entering "TEST 2"
        console.log('create type', $scope.groupType);

        // outputs the $scope for AppCreateCtrl but name and groupType
        // still show as "Custom Name" and "Custom Type"
        // $scope.$id is "007"
        console.log('scope', $scope);

        // outputs what looks like the scope, but in this object the
        // values for name and groupType are "TEST 1" and "TEST 2" as expected.
        // this.$id is set to "009" so this != $scope
        console.log('this', this);

        // based on what modalInstance.result.then() is saying,
        // the values that are in this object are the original $scope ones
        // not the ones the user has just entered in the UI. no data binding?
        $modalInstance.close({
            name: $scope.name,
            groupType: $scope.groupType
        });
    };
});

create.html（全部）

<div class="modal-header">
    <button type="button" class="close" ng-click="cancel()">x</button>
    <h3 id="myModalLabel">Add Template Group</h3>
</div>
<div class="modal-body">
    <form>
        <fieldset>
            <label for="name">Group Name:</label>
            <input type="text" name="name" ng-model="name" />           
            <label for="groupType">Group Type:</label>
            <input type="text" name="groupType" ng-model="groupType" />
        </fieldset>
    </form>
</div>
<div class="modal-footer">
    <button class="btn" ng-click="cancel()">Cancel</button>
    <button class="btn btn-primary" ng-click="ok()">Add</button>
</div>

因此，我的问题是：为什么作用域未与UI双重绑定？为什么this有自定义值，但$scope没有？

我试图ng-controller="AppCreateCtrl"在create.html中将它添加到主体div中，但这引发了一个错误：“未知提供程序：$
modalInstanceProvider <-$ modalInstance”，因此没有运气。

在这一点上，我唯一的选择是使用this.name和this.groupType而不是使用来传递对象$scope，但这感觉不对。

Answer 1

我让我这样工作：

var modalInstance = $modal.open({
  templateUrl: 'partials/create.html',
  controller: 'AppCreateCtrl',
  scope: $scope // <-- I added this
});

没有表格名称，没有$parent。我正在使用AngularUI Bootstrap版本0.12.1。

我通风报信该解决方案通过此。
