如何 Enable/Disable html 控件在 AngularJS 中的验证

Question

我有一个单选按钮组。第一个用于 "Inside Bangladesh"，第二个用于 "Outside Bangladesh"。如果我单击 "Inside Bangladesh"，地址字段（文本框）不需要验证，但是如果我单击 "Outside Bangladesh"，将触发地址字段所需的验证。看我下面的代码：

<ng-form id="validateReg" name="validateReg">
  <div ng-class="{'has-error': validateReg.chkInside.$invalid}">  
     <label>
           <input type="radio" id="radioInsideBD" required value="1" ng-model="chkInside" name="chkInside" />
           Inside Bangladesh
     </label>
     <label>
           <input type="radio" id="radioOutsideBD" required value="1" ng-model="chkInside" name="chkInside" />
           Outside Bangladesh
     </label>
   </div>
   <div ng-class="{'has-error': validateReg.address.$invalid}"> 
        Address: <textarea type="text" class="form-control" ng-model="address" name="address" id="address"></textarea>
   </div>
</ng-form>

Answer 1

 <div ng-class="{'has-error': (addressRequired ? validateReg.address.$invalid : false)}"> 
        Address: <textarea type="text" class="form-control" ng-model="address" name="address" id="address"></textarea>
   </div>

您应该 set/unset addressRequired 基于所选的单选按钮。

如果选择 Inside Bangladesh，则将其设置为 false，否则 true。
