Answer 1

在这种情况下，您可以简单地使用ngHide ：

<option value=".9" ng-hide="libr && age && (libr - age > 10)">Option 3 - IAV 6.0% Rider .90%</option>

Answer 2

try this

 <option ng-disabled="age >= 10" value=".9">Option 3 - IAV 6.0% Rider .90%</option>

here is the working fiddle

Answer 3

只需对要隐藏的DOM使用ng-hide="age - libr > 10" 。
