ng-selected无法在选择框中使用ng-model-Angular.js

问题描述：

在选择框中使用ng-model的情况下，同时在某些条件下ng-selected的时间不起作用的选项中也使用ng-selected的情况.

While ng-model is used in select box and ng-selected is also used in options with some condition that time ng-selected is not working.

如果我将删除ng-model而不是ng-selected正在工作，但是如果我将删除ng-model而不是我应该如何在控制器中获取选择框的值.

If I will remove ng-model than ng-selected is working, but if i will remove ng-model than how I should get the value of select box in controller.

请帮助！

这是我的代码...

HTML:

<select class="form-control" ng-change="accessModeSelected()">
     <option ng-selected="mode.status == '1'"  ng-repeat="mode in storageResult.accessMode" ng-value="mode.name" name="accessMode{{$index}}" id="accessMode">
           {{mode.name}}
     </option>
</select>

AngularJS:

$scope.storageResult   = {
           "storageAccount":"Enable", 
           "user": "sdcard",
           "pass": "sdcard",
           "wifiIP": "0",
           "ipAddr": "0",
           "accessMode": [
                {"name": "Local Storage","status": "0"},
                {"name":"WiFi Storage", "status": "1"},
                {"name":"Internet Storage", "status": "0"}
            ]
         }

答

使用ng-options和ng-init(用于设置默认值)代替ng-repeat.

Use ng-options and ng-init(for setting default value) instead of ng-repeat.

ng-options专为select

<select class="form-control" ng-init="statusselect='WiFi Storage'" ng-model="statusselect" ng-options="mode.name as mode.name for mode in storageResult.accessMode">

</select> Selected Value : {{statusselect}}

使用ng-repeat

我希望使用ng-options，但是如果要将ng-selected与ng-repeat结合使用，则需要从controller

I would prefer ng-options,but if you want to use ng-selected with ng-repeat you'll need provide a default selected value to ng-model from your controller

<select class="form-control" ng-model="statusselect">
     <option ng-selected="{{mode.name == statusselect}}" ng-repeat="mode in storageResult.accessMode" value="{{mode.name}}" name="accessMode{{$index}}" id="accessMode">
           {{mode.name}}
     </option>
</select> Selected Value : {{statusselect}}

内部控制器

$scope.storageResult  = {
           "storageAccount":"Enable", 
           "user": "sdcard",
           "pass": "sdcard",
           "wifiIP": "0",
           "ipAddr": "0",
           "accessMode": [
                {"name": "Local Storage","status": "0"},
                {"name":"WiFi Storage", "status": "1"},
                {"name":"Internet Storage", "status": "0"}
            ]
         }
   $scope.statusselect = $scope.storageResult["accessMode"][1]["name"];
