Answer 1

您可以在输入中添加“ng-true-value”属性作为示例

<input name="chkbx1" type="checkbox" ng-true-value="true"
                            ng-model="LoanReferData.Prop1"
                            ng-class="Submitted?'ng-dirty':''" required>Prop 1</input>

<input name="chkbx2" type="checkbox" ng-true-value="true"
                            ng-model="LoanReferData.Prop2" ng-class="Submitted?'ng-dirty':''"
                            required>Prop 2</input>

<input name="chkbx3" type="checkbox" ng-model="LoanReferData.Prop3" ng-true-value="true"
                            ng-class="Submitted?'ng-dirty':''" required>Other</input>

{{LoanReferData}}

这是一个答案

{"Prop1":"true","Prop2":"true","Prop3":false}

Answer 2

你可以试试！frmLoanRefer.LoanReferData.Prop1而不是frmLoanRefer.chkbx1。$ dirty。 frmLoanRefer.chkbx2也是一样。$ dirty和frmLoanRefer.chkbx3。$ dirty
