我想使用隔离范围来获取hideButtons
指令中的属性,todo-cardui
并且todo-formui
:
app.directive("todoFormui",function(TodoService){
var dirDefObj = {
restrict:'E',
templateUrl:'app/templates/edit-todo.html',
scope:{
hideButtons:"=hideButtons",
todo:"=todo"
},
controller:function($scope){
$scope.hideButtons = $scope.$parent.uiState.hideButtons;
//add a seperate model for editor and actions
console.log($scope.hideButtons);
$scope.model = {
todo:$scope.todo
};
$scope.uiState = {
editMode:true,
btnText:'Done'
};
$scope.actions = {};
$scope.actions.preview = function(){
console.log("Inside the edit to preview function");
$scope.uiState.editMode = false;
};
$scope.actions.save = function(){
TodoService.edit($scope.model.todo);
};
$scope.actions.discard = function(){
$scope.model.todo={
task:'',
dscription:'',
done:''
};
$scope.todo = $scope.savedState;
};
},
replace:true
};
return dirDefObj;
});
app.directive('todoCardui',function(TodoService){
var dirDefObj = {
restrict:'E',
templateUrl:'app/templates/display-todo.html',
scope:{
"hideButtons":"=hideButtons",
todo:"=todo"
},
replace:true,
controller:function($scope)
{ console.log($scope);
$scope.model = {
todo:$scope.todo
};
$scope.uiState = {
editMode:false,
btnText:'Done'
};
$scope.actions = {};
$scope.actions.clickDone = function clickDone(){
//two tasks (1)toggle the done value on the todo (2) toggle the btnText on the todo
$scope.model.todo.done = !$scope.model.todo.done;
$scope.uiState.btnText = $scope.todo.done?'Reinstate':'Done';
};
$scope.actions.remove = function remove()
{
TodoService.delete($scope.model.todo);
$scope.$emit('todo:deleted',$scope.model.todo);
};
$scope.actions.edit = function edit(value)
{
$scope.uiState.editMode = true;
console.log($scope.uiState.editMode);
};
}
};
return dirDefObj;
});
它们的父级是一个名为的指令create-modal
,如下所示:
app.directive('modalCreate',['$log','TodoService',function($log,TodoService) {
var dirDefObj = {
restrict:'E',
scope:{},
templateUrl:'app/templates/create-todo.html',
controller:function($scope,TodoService)
{
$scope.model = {};
$scope.actions = {};
$scope.uiState = {};
$scope.model.todo ={
task:'What do you want to do?',
description:'Lorem Ipsum Dolar...screw it'
};
$scope.uiState.hideButtons = true;
$scope.actions.show_modal=function show_modal()
{
if(!$('.create-modal').modal('is active'))
$('.create-modal').modal('show');
};
$scope.actions.saveTodo = function saveTodo(){
TodoService.save($scope.todo);
$('.create-modal').modal('hide');
};
$scope.actions.cancel = function cancel(){
$log.info("Cancel the todo action,currently a no-op");
$('.create-modal').modal('hide');
};
},
replace:true
};
return dirDefObj;
}]);
我使用这样的代码:
<div class="ui segment">
<button class="ui button" ng-click="actions.show_modal()">Create Todo</button>
<div class="ui modal create-modal">
<i class="ui icon close" ng-click="cancel()"></i>
<div class="header">Create Todo</div>
<div class="content">
<todo-formui hideButtons="uiState.hideButtons" todo="model.todo"></todo-formui>
<div class="ui vertical divider">
<span class="ui teal circular label">Is</span>
</div>
<div class="preview">
<todo-cardui hideButtons="uiState.hideButtons" todo="model.todo"></todo-cardui>
</div>
</div>
<div class="actions">
<button type="button" class="ui button green save-button" ng-click="actions.saveTodo()">Save</button>
<button type="button" class="ui button red delete-button" ng-click="actions.cancel()">Cancel</button>
</div>
</div>
该物业hideButtons
尚未被取走。todo
我也尝试过:
$scope.hideButtons = $scope.$parent.uiState.hideButtons;
这会引发错误:
