ng-form和ng-submit在ng-repeat中

Question

我一直在尝试获取一个嵌套表单来正确验证，然后在单击“提交”按钮时在控制器上调用一个函数。 我尝试删除除提交按钮之外的所有按钮，但它不起作用。 我唯一能够开始工作的就是Ng单击按钮，但是我需要验证，并且此方法不允许触发验证。

这是Controller和HTML中的方法，如果通过ng-click调用则可以使用

  saveRow(row: ControlDetailDTO) { row.FiscalYearValues.forEach(value => { value.ActualValue = value.PreviousYear + value.DeltaValue; }); this.controlsDataContext.saveDetail(row).then((results) => { console.log(results); row.editMode = false; }).catch((err) => { this.$scope.error = err.data.ExceptionMessage; }); } 

 <table class="table table-striped table-responsive"> <tr ng-repeat-start="control in newControl.ControlDetails" class="headerLightBlue" ng-show="$first" ng-form="edit"> <th colspan="2">Category</th> <th>Description</th> <th>{{control.FiscalYearValues[0].FiscalYear.FiscalYearName }}</th> <th>{{control.FiscalYearValues[1].FiscalYear.FiscalYearName }}</th> <th>{{control.FiscalYearValues[2].FiscalYear.FiscalYearName }}</th> <th>{{control.FiscalYearValues[3].FiscalYear.FiscalYearName }}</th> <th>{{control.FiscalYearValues[4].FiscalYear.FiscalYearName }}</th> <th>{{control.FiscalYearValues[5].FiscalYear.FiscalYearName }}</th> <th></th> <tr> <ng-form name="edit" ng-submit="saveRow(control)" novalidate> <td ng-show="control.editMode" colspan="2"><select name="Category" class="form-control" id="Category" required ng-model="control.Category" ng-options="category.CategoryName for category in categories track by category.Id"><option value="">Select Appropriation</option></select></td> <td ng-show="!control.editMode" colspan="2">{{control.Category.CategoryName}}</td> <td ng-show="!control.editMode">{{control.Description}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[0].DeltaValue)">{{control.FiscalYearValues[0].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[1].DeltaValue)">{{control.FiscalYearValues[1].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[2].DeltaValue)">{{control.FiscalYearValues[2].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[3].DeltaValue)">{{control.FiscalYearValues[3].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[4].DeltaValue)">{{control.FiscalYearValues[4].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="!control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[5].DeltaValue)">{{control.FiscalYearValues[5].DeltaValue | inThousands | currency : $ : 0}}</td> <td ng-show="control.editMode"><input name="Description" class="form-control input-md" id="Description" required="" type="text" placeholder="" ng-model="control.Description"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[0].DeltaValue)"><input name="FY0" class="form-control input-md" id="FY0" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[0].DeltaValue"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[1].DeltaValue)"><input name="FY1" class="form-control input-md" id="FY1" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[1].DeltaValue"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[2].DeltaValue)"><input name="FY2" class="form-control input-md" id="FY2" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[2].DeltaValue"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[3].DeltaValue)"><input name="FY3" class="form-control input-md" id="FY3" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[3].DeltaValue"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[4].DeltaValue)"><input name="FY4" class="form-control input-md" id="FY4" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[4].DeltaValue"></td> <td ng-show="control.editMode" ng-style="common.setColorCurrency(control.FiscalYearValues[5].DeltaValue)"><input name="FY5" class="form-control input-md" id="FY5" required="" type="number" placeholder="" required ng-model="control.FiscalYearValues[5].DeltaValue"></td> <td ng-show="!control.editMode"><button name="button3id" ng-show="control.isEditable && $last" class="btn btn-success" ng-click="editRow(control)" id="button3id" popover-trigger="mouseenter" popover="Edit"><i class="fa fa-edit"></i></button></td> <td ng-show="control.editMode" width="100px"><button name="button3id" class="btn btn-danger" ng-click="cancelEdit(control)" id="button3id" popover-trigger="mouseenter" popover="Cancel Changes"><i class="fa fa-undo"></i></button>&nbsp;<button type="submit" class="btn btn-success" id="saveRow" popover-trigger="mouseenter" popover="Save Changes"><i class="fa fa-save"></i></button></td> </ng-form> </tr> <table>

ng-repeat为每个重复的项目创建子范围，而我的猜测是存在范围可见性问题，这阻碍了验证的进行。

考虑使用ng-form指令：
