You could try to use ng-class  Here is my simple example  http   plnkr co edit wS3QkQ5dvHNdc6Lb8ZSF p preview   lt div ng-repeat  object in objects  gt     lt span ng-class    disabled   object status   ng-click  disableIt object   gt        object value      lt  span gt   lt  div gt    The status is a custom attribute of object  you could name it whatever you want  The disabled in ng-class is a CSS class name  the object status should be true or false  You could change every object s status in function disableIt  In your Controller  you could do this    scope disableIt   function obj      obj status    obj status

I use the  amp  amp  expression which works perfectly for me    For example    lt button ng-model  vm slideOneValid  ng-disabled   vm slideOneValid  ng-click  vm slideOneValid  amp  amp  vm nextSlide    class  btn btn-light-green btn-medium pull-right  gt Next lt  button gt    If vm slideOneValid is false  the second part of the expression is not fired  I know this is putting logic into the DOM  but it s a quick a dirty way to get ng-disabled and ng-click to place nice    Just remember to add ng-model to the element to make ng-disabled work

I had this issue also and I simply found out that if you simply remove the     the issue goes off  Like this     lt a href    class  disabled  ng-click  doSomething object   gt Do something lt  a gt

We can add ng-click event conditionally without using disabled class   HTML     lt div ng-repeat  object in objects  gt   lt span ng-click   object status  amp  amp  disableIt object   gt   object value   lt  span gt   lt  div gt

It is not good to manipulate with DOM  including checking of attributes  in any place except directives  You can add into scope some value indicating if link should be disabled   But other problem is that ngDisabled does not work on anything except form controls  so you can t use it with  lt a   but you can use it with  lt button  and style it as link   Another way is to use lazy evaluation of expressions like isDisabled    action   so action wouold not be called if isDisabled is true   Here goes both solutions  http   plnkr co edit 5d5R5KfD4PCE8vS3OSSx p preview

Basically ng-click first checks the isDisabled and based on its value it will decide whether the function should be called or not    lt span ng-click   isDisabled     clicked    gt Do something lt  span gt    OR read it as   lt span ng-click   if this value is true function clicked won t be called  and if it s false the clicked will be called     clicked    gt Do something lt  span gt
