Javascript ng init总是在浏览器控制台中给出错误

我正在使用ng init表达式将选定下拉列表中的值指定给viewModel。功能正常工作。但它在浏览器控制台中显示了很多错误。谁能帮我一下吗

<div class="form-group">
                            <label class="control-label col-md-3">Approve Status:</label>
                            <div class="col-md-4">
                                <select ng-disabled="true" ng-init="{{obj.ApproveID=selectedApproveStatus.DropdownUtilityID}}" ng-model="selectedApproveStatus" data-ng-options="option.DropdownUtilityName for option in approveStatus track by option.DropdownUtilityID" class="form-control"></select>
                            </div>
                        </div>

ng init

的语法是

ng init=“expression”

，您不应该将它用大括号（{{{}）括起来

试试这个：

批准状态：

您不需要

{{

在

ng init

中，当我删除大括号时，功能不起作用错误不显示，但当我更改下拉选项值时，obj.Approved没有显示。obj是否在您的范围内？当您更改选择时，似乎要将值指定为obj.Approved。然后使用ng-change@ParthaSarathiGhosh，没错！那么，w你为什么想要

nginit

，只需设置模型值。就这样。。。
