将数据传递给引导模式

I think I'm missing something but cannot figure what.
Basically I'm trying to pass an object to the modal like below, but instead of getting the passed object I gets null...so I think is a problem with the scope but I'm new in Angular and need some help.

我想我错过了什么，但我不知道是什么。基本上，我尝试将一个对象传递给模态，如下所示，但是我没有获得传递的对象，而是获得null…所以我认为这是范围的问题，但我是角度的新手，需要一些帮助。

Controller

控制器

app.controller("musicViewModel", function ($scope, $http, $location, $uibModal, $log) {

$scope.selected = null;

$scope.open = function (item) {

    $scope.selected = item;

    $log.info('Open' + $scope.selected); // get right passes object

    var modalInstance = $uibModal.open({
        templateUrl: 'myModalContent.html',
        controller: 'musicViewModel',
        size: 'lg',
        resolve: {
            items: function () {
                return $scope.selected;
            }
        }
    });
};

$scope.toggleAnimation = function () {
    $scope.animationsEnabled = !$scope.animationsEnabled;
};
});

View

视图

<div class="row" ng-controller="musicViewModel">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3 class="modal-title">I'm a modal!</h3>
        </div>
        <div class="modal-body">
            <ul>
                <li>
                    {{ selected }} // always gets null
                </li>
            </ul>
        </div>
    </script>
</div>

4 个解决方案

#1

I'd suggest you to pass the scope of your own controller instead of passing same controller again, by doing that you can remove the resolve also.

我建议您传递您自己的控制器的范围，而不是再次传递相同的控制器，通过这样做，您也可以删除解决方案。

var modalInstance = $uibModal.open({
    templateUrl: 'myModalContent.html',
    scope: $scope, //passed current scope to the modal
    size: 'lg'
});

Otherwise you need to create a new controller and assign that controller for modal while opening it.

否则，您需要创建一个新的控制器，并在打开它时为modal分配该控制器。

#2

When you use resolve, the map is injected into the given controller.

当您使用resolve时，映射被注入到给定的控制器中。

I recommend that u use a different controller to handle the modal functionality (separation of concerns).

我建议您使用不同的控制器来处理模式功能(关注点分离)。

I also recommend to use dependency injection to support minification of the code. Step 5 on the Angular tutorial wil explain this.

我还建议使用依赖注入来支持代码的缩小。第5步，在角度教程中，wil解释了这一点。

A simplified example of the modal controller would be.

模态控制器的一个简化示例是。

(function () {

    'use strict';

    var app = angular.module('App');

    app.controller('musicDetailController',

                ['$scope', '$uibModalInstance', 'items',
        function ($scope, $uibModalInstance, items) {

            $scope.items = items;

        }]);
}());

#3

You cannot pass an object directly.

不能直接传递对象。

I've tried all the solutions above, but wasn't really satisfied. I've solved the issue by writing a simple parser that enables you to pass both strings and objects directly to the modal, through the provided resolve function.

我尝试了以上所有的解决方案，但并不满意。我通过编写一个简单的解析器来解决这个问题，该解析器允许您通过提供的resolve函数将字符串和对象直接传递给modal。

app.controller('ModalController', ['$uibModal', '$scope', function ($uibModal, $scope) {

    // Initialize $modal
    var $modal = this;

    // Open component modal
    $modal.open = function (component, size, data) {

        // Init modal
        var modalInstance = $uibModal.open({
            ariaLabelledBy: 'modal-title',
            ariaDescribedBy: 'modal-body',
            component: component,
            size: size || 'md',
            resolve: parseResolve(data)
        });
    };

    // Parse the resolve object
    function parseResolve(data) {
        if (typeof data === 'string') {
            return {
                data: function() {
                    return data;
                }
            }
        }
        else if (typeof data === 'object') {
            var resolve = {};
            angular.forEach(data, function(value, key) {
                resolve[key] = function() {
                    return value;
                }
            })
            return resolve;
        }
    }

}]);

When usings strings

当usings字符串

Template:

模板:

<button ng-click="$modal.open('modalSomething', 'md', 'value'">
    Click
</button>

Component:

组件:

bindings: {
    resolve: '@'
}

---

When using objects

当使用对象

Template:

模板:

<button ng-click="$modal.open('modalSomething', 'md', {key1: value1, key2: value2})">
    Click
</button>

Component:

组件:

bindings: {
    resolve: '<'
}

I got the below code working:

我让下面的代码工作:

this.OpenModal = function() {
        var modalInstance = $uibModal.open({
            url: "/name?parameter=" + $scope.Object.ParamValue,
            templateUrl: 'views/module/page.html',
            controller: myController
        });
    }
