我试图填充body属性,因此我的模块会将其打印为它的正文部分,但我不知道为什么它不起作用,即使我尝试了$ scope。 $ apply()在几个地方。
var app = angular.module('ClientLogger', ['ngRoute'])
app.controller('global', function($scope, $compile) {
$scope.window = window
$scope.sampletext = "sampleText";
$scope.showModal = false;
$scope.toggleModal = function(text) {
$scope.text = text;
$scope.showModal = !$scope.showModal;
};
});
app.directive('modal', function() {
return {
template: '<div class="modal fade">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>' +
'<h4 class="modal-title">{{ title }}</h4>' +
'</div>' +
'<div class="modal-body" ng-transclude> {{ body }} </div>' +
'</div>' +
'</div>' +
'</div>',
restrict: 'E',
transclude: true,
replace: true,
scope: true,
link: function postLink(scope, element, attrs) {
scope.title = attrs.title;
scope.body = attrs.body;
scope.$watch(attrs.visible, function(value) {
if (value == true)
$(element).modal('show');
else
$(element).modal('hide');
});
$(element).on('shown.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = true;
});
});
$(element).on('hidden.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = false;
});
});
}
};
});
&#13;
<body ng-app='ClientLogger' ng-controller='global'>
<a class="btn btn-default" ng-click="toggleModal(sampletext)"> sample </a>
<modal title="Message Details" body="{{text}}" visible="showModal"></modal>
</body>
&#13;
正如您所看到的,在我点击链接后,它将更改变量$ scope.text,它将反映到模态。但我无法做到这一点。由于我对这个Angular很新,我仍然有理解其机制的麻烦,所以任何具体的细节对我来说都是非常好的。 有什么建议吗?

检索attrs.body
时,您正在检索未定义数据。
您可以使用工厂来共享您的数据。您必须知道所有角度服务都是单例,因此只有一个给定服务的实例。
由于这个原因,您可以轻松地在控制器和指令之间共享数据。
因此,当您在Controller中触发操作时,您将数据设置到工厂中,然后您可以将数据检索到指令中。
<强>控制器强>
(function(){
function Controller($scope, Service) {
$scope.myText = 'sample';
$scope.showModal = false;
$scope.toggleModal = function() {
//Set the myText value by using our Service.set() method
Service.set($scope.myText);
$scope.showModal = !$scope.showModal;
};
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
<强>服务强>
(function(){
function Service(){
var data;
function set(value){
data = value;
}
function get(){
return data;
}
return {
get: get,
set: set
};
}
angular
.module('app')
.factory('Service', Service);
})();
<强>指令强>
(function(){
function modal(Service) {
return {
template: '<div class="modal fade">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>' +
'<h4 class="modal-title">{{ title }}</h4>' +
'</div>' +
'<div class="modal-body"> {{ body }} </div>' +
'</div>' +
'</div>' +
'</div>',
restrict: 'E',
transclude: true,
replace: true,
scope: true,
link: function (scope, element, attrs) {
scope.title = attrs.title;
scope.$watch(attrs.visible, function(value) {
value
//Retrieve your data by using Service.get() method, and show our modal
? ( scope.body = Service.get(), $(element).modal('show') )
: $(element).modal('hide')
});
$(element).on('shown.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = true;
});
});
$(element).on('hidden.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = false;
});
});
}
};
}
angular
.module('app')
.directive('modal', modal);
})();
然后,您可以将您的指令调用到您的HTML中。
<强> HTML 强>
<body ng-app='app' ng-controller="ctrl">
<input type="text" ng-model="myText">
<a class="btn btn-default" ng-click="toggleModal()"> sample </a>
<modal title="Message Details" visible="showModal"></modal>
</body>
