Browser Compatibility

All major browsers support the onload event attribute.

Definition and Usage

The onload attribute is triggered after the object is loaded.
Once the web page has completely loaded all content (including images, script files, CSS files, etc.), onload is typically used within the <body> element to execute scripts. However, it can also be used on other elements (see the following 'Supported HTML Tags').
The onload attribute can be used to check the visitor's browser type and version, and load the correct version of the web page based on this information.
The onload attribute can also be used to handle cookies.
