HTF

The HTF (hypertext functions) and HTP (hypertext procedures) packages generate HTML tags. For example, the HTF.ANCHOR function generates the HTML anchor tag, <A>.

HTF Deprecated Subprograms

The ESCAPE_URL function is deprecated with Oracle Database 10g.

Note: Oracle recommends that you do not use deprecated procedures in new applications. Support for deprecated features is for backward compatibility only.

HTF Operational Notes

These operational notes apply to the HTF package.

For every HTF function that generates one or more HTML tags, there is a corresponding HTP procedure with identical parameters with the following exception:

The function versions do not directly generate output in your Web page. Instead, they pass their output as return values to the statements that invoked them. Use these functions when you need to nest calls. To print the output of HTF functions, call the functions from within the HTF.PRINT function. It then prints its parameters to the generated Web page.

Rules and Limits

If you use values of the LONG datatype in functions such as HTF.PRINT, HTF.PRN, HTF.PA or OWA_UTIL.CELLSPRINT, only the first 32 K of the LONG data is used. The LONG data is bound to a VARCHAR2 datatype in the function.

HTF Examples

The commands in this example generate a simple HTML document.

CREATE OR REPLACE PROCEDURE hello AS
BEGIN
   HTP.P (HTF.HTMLOPEN); -- generates <HTML>
   HTP.P (HTF.HEADOPEN); -- generates <HEAD>
   HTP.P (HTF.TITLE('Hello')); -- generates <TITLE>Hello</TITLE>
   HTP.P (HTF.HEADCLOSE); -- generates </HEAD>
   HTP.P (HTF.BODYOPEN); -- generates <BODY>
   HTP.P (HTF.HEADER(1, 'Hello')); -- generates <H1>Hello</H1>
   HTP.P (HTF.BODYCLOSE); -- generates </BODY>
   HTP.P (HTF.HTMLCLOSE); -- generates </HTML>
END;

   cnowrap        IN       VARCHAR2   DEFAULT NULL
   cclear         IN       VARCHAR2   DEFAULT NULL
   cattributes    IN       VARCHAR2   DEFAULT NULL)
 RETURN VARCHAR2;

Parameters

Table 2 ADDRESS Function Parameters

Parameter Description
cvalue The string that goes between the <ADDRESS> and </ADDRESS> tags.
cnowrap If the value for this parameter is not NULL, the NOWRAP attribute is included in the tag
cclear The value for the CLEAR attribute.
cattributes The other attributes to be included as-is in the tag

Examples

This function generates

<ADDRESS CLEAR="cclear" NOWRAP cattributes>cvalue</ADDRESS>

ANCHOR Function

Like the ANCHOR2 function, this function generates the <A> and </A> HTML tags which specify the source or destination of a hypertext link.

The difference between these subprograms is that the ANCHOR2 Function provides a target and therefore can be used for a frame.

Syntax

HTF.ANCHOR (
   curl           IN       VARCHAR2,
   ctext          IN       VARCHAR2,

Examples

This function generates

<A HREF="curl" NAME="cname" cattributes>ctext</A>

Usage Notes

This tag accepts several attributes, but either HREF or NAME is required. HREF specifies to where to link. NAME allows this tag to be a target of a hypertext link.

ANCHOR2 Function

Like the ANCHOR function, this function generates the <A> and </A> HTML tags which specify the source or destination of a hypertext link.

The difference between this and the ANCHOR function is that this function provides a target and therefore can be used for a frame.

Syntax

HTF.ANCHOR2 (
   curl           IN       VARCHAR2,
   ctext          IN       VARCHAR2,

   cattributes    IN       VARCHAR2   DEFAULT NULL)
 RETURN VARCHAR2;

Parameters

Table 4 ANCHOR2 Function Parameters

Parameter Description
curl The value for the HREF attribute.
ctext The string that goes between the <A> and </A> tags.
cname The value for the NAME attribute
ctarget The value for the TARGET attribute.

so that, for example,

HTF.appletopen('testclass.class', 100, 200, 'CODEBASE="/ows-applets"')

generates

<APPLET CODE="testclass.class" height=100 width=200 CODEBASE="/ows-applets">
