# pageIndex

### app.pageIndex

Type: **Number**

Returns the index of the active page in your app's layout.

### Examples

```
// display the current page index in the debugger
debug.log(app.pageIndex);
```

### Remarks

Page indexes are **zero-based**. This means the first page will have an index value of 0 and the third page will have an index value of 2.

          Zero-Based Indexing

          

**Zero-based** indexing seems strange at first, but it's how programming languages (i.e. JavaScript) work with collections of things.
