onmousemove Attribute

Where to use the onmousemove Attribute

Description

The onmousemove attribute is a common attribute which may be used on most elements to specify script to be executed when the mouse pointer is moved within the element.

See also the onmouseover and onmouseout attributes.

If you use this attribute (or any attributes of Type Script) the MIME type of the scripting language used should always be provided in a Content-Script-Type HTTP header.

It is good practice not to use these attributes, however, and instead to include external scripts (via script elements) which add any handlers unobtrusively. This makes code more self-contained and also the XHTML is easier to maintain if it doesn't contain any events attributes.
