title: ng-disabled is not working in Firefox and chrome
body: <p>Currently I'm working on a project related to AngularJS. In there I need to disabled on </p>
  
  <p>&lt; a ></p>
  
  <p>link. To do that I used <strong>ng-disabled="true"</strong>. This is not working in chrome and Firefox. But it works in IE. Someone suggested the change  link to a button. But in this project I can't convert those links to buttons.  Does anyone know how to do so?</p>
