Here is an example comparing multiple angular-ui-router states using the OR    operator     lt li ng-class                 warning               state includes  out pay code wrong                   state includes  out pay failed                     active               state includes  out pay           gt    It will give the li the classes warning and or active  depening on whether the conditions are met

To apply different classes when different expressions evaluate to true    lt div ng-class   class1   expression1  class2   expression2   gt      Hello World   lt  div gt    To apply multiple classes when an expression holds true    lt  -- notice expression1 used twice -- gt   lt div ng-class   class1   expression1  class2   expression1   gt      Hello World   lt  div gt    or quite simply    lt div ng-class    class1 class2    expression1   gt      Hello World   lt  div gt    Notice the single quotes surrounding css classes

Using a  scope method on the controller  you can calculate what classes to output in the view  This is especially handy if you have a complex logic for calculating class names and it will reduce the amount of logic in your view by moving it to the controller   app controller  myController   function  scope          scope className   function              var className    initClass            if  condition1                className      class1            if  condition2                className      class2            return className               and in the view  simply    lt div ng-class  className    gt  lt  div gt

Your example works for conditioned classes  the class name will show if the expressionDataX is true       lt div ng-class   class1  expressionData1  class2  expressionData2   gt  lt  div gt   You can also add multiple classes  supplied by the user of the element      lt div ng-class   class1  class2   gt  lt  div gt   Usage    lt div class  foo bar  class1  foo  class2  bar  gt  lt  div gt
