[英]Angular-Material : md-select in md-dialog not closing
[英]Angular-Material , AngularJS , TypeScript , Javascript , ng-controller not accessible within my md-dialog
我的代碼中有一個問題,我正在嘗試使用ng-controller調用我的用戶(在索引上聲明'ng-controller =“mainController as vm”')我可以在我的代碼中使用它訪問用戶並獲取他的電子郵件和圖像。 但是現在我希望能夠在你點擊我的圖像時打開一個md對話框,這樣圖像就可以在對話框中放大,我的對話框打開但是我無法訪問我的控制器(vm)來說明他要顯示的圖像。
這將打開我的內容頁面中的圖像:
<img src="{{vm.selected.item4}}" />
順便說一下
這就是我打開對話框的方式:
<md-button ng-click="vm.showDialog($event)" >
<img src="{{vm.selected.item1}}"/>
</md-button>
我的對話框打開但它不會顯示圖像...有沒有人知道如何解決這個問題?
(如果我的主題或問題的格式不正確,請先對不起,我對此很陌生,因此,如果某些內容不符合我的要求,請糾正我。)
有幾種方法可以將值從父作用域傳遞到對話框。 以下是3個示例用法。 你可以使用這個codepen來玩它們。
.controller('AppCtrl', function ($scope, $mdDialog) {
$scope.imageUrl = "https://upload.wikimedia.org/wikipedia/commons/1/18/Bradypus.jpg";
// Show the image in the dialog by using parent scope directly in the template.
$scope.showDialog = function(ev) {
$mdDialog.show({
template: '<img src="' + $scope.imageUrl + '"></img>',
parent: angular.element(document.querySelector('#popupContainer')),
targetEvent: ev,
clickOutsideToClose: true,
ariaLabel: 'Dialog 1',
});
}
// Get the image from the function call and use directly in the template
$scope.showDialog2 = function(ev, image) {
$mdDialog.show({
template: '<img ng-src="' + image + '"></img>',
parent: angular.element(document.querySelector('#popupContainer')),
targetEvent: ev,
clickOutsideToClose: true,
ariaLabel: 'Dialog 2'
});
}
// Show the image by defining locals. This is the most elegant way,
// IMO. You can make any value available by defining locals. After
// defining locals, you can use the defined locals in your dialog
// controller. After you get the locals from your controller, you can
// easily use them in your dialog's template.
$scope.showDialog3 = function(ev) {
$mdDialog.show({
template: '<img ng-src="{{image}}"></img>',
parent: angular.element(document.querySelector('#popupContainer')),
targetEvent: ev,
clickOutsideToClose: true,
ariaLabel: 'Dialog 3',
locals: {image: $scope.imageUrl},
controller: function($scope, $log, image) {
$scope.image = image;
}
});
}
});
HTML:
<div ng-app="MyApp">
<div ng-controller="AppCtrl">
<md-content id="popupContainer" style="height: 500px;">
<md-button class="md-raised md-primary" ng-click="showDialog($event)">
Open Dialog
</md-button>
<md-button class="md-raised md-primary" ng-click="showDialog2($event, imageUrl)">
Open Dialog 2
</md-button>
<md-button class="md-raised md-primary" ng-click="showDialog3($event)">
Open Dialog 3
</md-button>
</md-content>
</div>
</div>
