Element-Specific Attributes
action
This attribute specifies the URL of the query action to be executed when the viewer
presses the
ENTER
key. Although this attribute is not defined under any HTML specification,
it is common to many browsers, particularly Internet Explorer 3, which defined it.
prompt
This attribute allows a custom query prompt to be defined. The default prompt is
“This is a searchable index. Enter search keywords.”
Examples
<isindex action="cgi-bin/search.pl" prompt="Enter search terms">
<!-- very old HTML style syntax below -->
<base href="cgi-bin/search">
<isindex prompt="Enter search terms">
<isindex href="cgi-bin/search" prompt="Keywords:">

Notes
• Originally, the W3C intended this element to be used in a document's header.
Browser vendors have relaxed this usage to allow the element in a document's body.
Early implementations did not support the
action
attribute and used a
<base>
tag
or an
href
attribute to specify a search function's URL.
• As an empty element,
<isindex>
requires no closing tag under HTML specifications.
However, under the XHTML specification, a trailing slash
<isindex />
is required.
• The HTML 3.2 specification only allows the
prompt
attribute, whereas HTML 2
expected a text description to accompany the search field.
