Definition and Usage
The pagebeforeload event was deprecated in jQuery version 1.4.0. Use the pagecontainerbeforeload event instead.
The pagebeforeload event is triggered before any load request is made.
Related events:
- pageload - triggered after the page has been successfully loaded and inserted into the DOM
- pageloadfailed - triggered if the page load request fails
Note: These events are used for external pages - Whenever an external page is loaded into the DOM, 2 events are fired. The first is pagebeforeload. The 2nd event will either be pageload or pageloadfailed.
