How to disable link depending on value in angular?

Question

Angular

There is a link

<a href="{{data}}"></a>
{{значение}}

It is necessary that it does not work if the value = 0.
Ng-show does not help

Answer 1

1) if you are making a dynamic link, then it is better to use ng-href rather than href
2) it should definitely hide the link if it is in data 0
3) it is better to see the context, because there may be a problem with scopes
