Angularjs 角度引导ui模式作用域与父级绑定

我在获取一个模态范围以从父范围解除绑定时遇到角度问题。我希望传递到模态中的范围对象与相应的范围对象分开

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

无论我如何构造模态对象，父对象总是镜像它。我找到的唯一解决方案是更改对象属性名称，但对于我的项目中的每个模式来说，这样做都很麻烦

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

例如，我可以在父级$scope.parentData.firstName中有一个$scope变量和一个模态变量$scope.modalData.a.b.c.firstName，父级将镜像模态值

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

我想这里有一些父子$scope问题，我没有得到。 下面是一个例子来说明这个问题：

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

HTML:

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

您正在传递对当前对象的引用，您要做的是将对象的深度副本传递给模式：

<div ng-controller="ModalDemoCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
                <input ng-model="modalData.a" />
                <input ng-model="modalData.b" />
                <input ng-model="modalData.c" />
            Selected: <b>{{ sourceData }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    {{sourceData}}
    <div ng-show="sourceData">Selection from a modal: {{ test }}</div>
</div>
  </body>
</html>

只需使用

angular.copy（object）

。必须记住，除非克隆对象，否则对象是通过引用传递的。这与angular无关，这是本机javascript原型继承问题。修改副本后，如果要再次将它们合并在一起，请使用

angular.extend（）

“$scope.ok=function（）{$modalInstance.close（$scope.modalData）；}；”；它是唯一可以将数据返回到父控制器的函数还是有其他方法？干杯
