How to use expression in ng-href for passing query parameters?

Question

<a ng-href="{{a==3 ? 'www.google.com/correct?{{a}}' : 
'www.google.com/correct?{{a+1}}'}}"

It throws error.

Error: $parse:lexerr Lexer Error

Can anyone help please. I am new to angularjs and learning, not able to figure out how should I proceed.

Please use:

ng-href="a===3 ? ('www.google.com/correct?' + a) : ('www.google.com/correct?' + (a+1))"

Since it's an ng-tag, you shouldn't use brackets, and treat it like regular javascript.
