Set class in angular if variable is defined?

Question

I'm trying to set the class "expanded" to a div if the variable is undefined. I attempted this, but had no success. What am I doing wrong? ``` {'expanded': typeof member != 'undefined'} ```

Accepted Answer

You can do it easier:

```
 ng-class="{'expanded':  member != undefined}"
```

or even:

```
ng-class="{'expanded':  member }"
```
