HTML <isindex> (Index Prompt) Tag
Deprecated: Not Supported in HTML5.
Example
<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:">Meaning
The <isindex> element specifies that a document has an associated searchable keyword index.
When a browser encounters this element, it inserts a query entry field at that point in the document. The viewer can enter query terms to perform a search.
This element is deprecated under the strict HTML and XHTML specifications and should not be used.
Notes:
- This element is not found at all in newer specifications like HTML5.
- As an empty element, <isindex> requires no closing tag under HTML specifications. However, under the XHTML specification, a trailing slash <isindex /> is required.
Version: HTML 2, 3.2, 4, 4.01 (transitional)
