我是 AngularJS 的完整初学者。现在我想使用 ui.bootstrap $uibModal 服务创建对话链。我想从 .txt 文件接收数据到对话框。这意味着，我最初不会知道链中对话的数量，它将取决于 .txt 数据。现在我尝试用循环来做到这一点，但它很愚蠢，然后我将无法拥有诸如“上一个”、“下一个”、确定和取消之类的功能。有没有明智的解决方案来做到这一点？预先感谢您的回答。
var app = angular.module('myApp', ['ui.bootstrap']);
angular.module('myApp').config(['$uibModalProvider', function($uibModalProvider) {
$uibModalProvider.options.windowClass = 'show';
$uibModalProvider.options.backdropClass = 'show';
}]);
app.factory('modalDialog', function($uibModal) {
var arr_items = [];
var showModalDialog =function(items) {
return $uibModal.open({
templateUrl: 'test.html', //just the dialog body for the info
animation: true,
size: 'sm',
ariaLabelledBy: 'modal-title',
ariaDescribedBy: 'modal-body',
controller: 'dialogCtrl',
controllerAs: "$ctrl",
resolve: { items: function () { console.log("items before travelling" + JSON.stringify(items));
return items; } }
});
}
return {showModalDialog: showModalDialog};
});
app.controller('TestCtrl', function($scope, $http, modalDialog){
$scope.cancelled = false;
$scope.test = function(){
$http.get('test.txt')
.then(function(response) {
$scope.items=response.data;
for (var i=0; i<$scope.items.length; i++) {
console.log($scope.cancelled);
if ($scope.cancelled) return ;
var showModalDialog = function() {
console.log("here");
modalDialog.items = $scope.items[i];
modalDialog.showModalDialog($scope.items[i]);
};
showModalDialog();
};
});
};
});
app.controller('dialogCtrl', function ($scope, $uibModalInstance, items) {
var $ctrl =this;
console.log("here are my items" + items.request + " " + JSON.stringify(items));
$scope.items = items;
$ctrl.ok = function () {
$uibModalInstance.close($scope.items);
};
$ctrl.cancel = function () {
console.log("cancel");
$scope.cancelled = true;
return $uibModalInstance .dismiss('cancel');
};
