我在理解/使用有角度的 UI 模式的范围方面有困难。
虽然这里不是很明显,但是我已经正确地设置了模块和所有东西(据我所知) ,但是这些代码示例是我发现 bug 的地方。
.html (它的重要部分)
<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>
Js (同样是重要的部分)
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 (完整的)
<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: 为什么作用域没有被双重绑定到 UI?为什么 this
有定制的值,而 $scope
没有?
我尝试将 ng-controller="AppCreateCtrl"
添加到 create.html 的 body div 中,但是抛出了一个错误: “ Unknown Provider: $modalInstanceProvider <-$modalInstance”,所以没有找到。
此时,我唯一的选择是使用 this.name
和 this.groupType
返回一个对象,而不是使用 $scope
,但这感觉不对。
