onselect Attribute

Where to use the onselect Attribute

• As Type Script:
  onselect is declared on the elements: input type="text", input type="password", input type="file", textarea

Description

The onselect attribute may be used to specify script to be executed when some text within the element's text box is highlighted by the user.

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.
