## Definition and Usage
This event is deprecated since version 1.4.0, use (#) instead.
The pageinit event is triggered after the page is initialized and jQuery Mobile has finished enhancing the page content.
Use this event instead of the jQuery DOM ready event, because it will trigger regardless of whether the page is loaded directly or via an Ajax call.
**Note:** This event can only be triggered once per page - when the page is loaded for the first time, jQuery Mobile caches the page in the DOM (memory), so when you navigate back to the first page from the second page using the browser, this event will not be triggered, because the first page has already been initialized.
**Related Events:**
- Triggered before page initialization and before jQuery Mobile starts enhancing the page.
- Triggered after the page is created successfully, but before the page enhancement is complete.

## Syntax
To trigger all page events in jQuery Mobile:
```javascript
$("document").on("pageinit",function(event){...})
(#)
To trigger a specific page event:
```javascript
$("document").on("pageinit","_page_",function(event){...})
(#)
| Parameter | Description |
