135 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>.

Operational Notes

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 PRINTS Procedure and the PS Procedure do not have HTF function equivalents. Use the ESCAPE_SC Function or the ESCAPE_URL Function if you need a string conversion function. Note that while there is a ESCAPE_SC Procedure that performs the same operation as the PRINTS Procedure and the PS Procedure, there is no procedural equivalent for the ESCAPE_URL Function.
The FORMAT_CELL Function does not have an HTP equivalent. The function formats column values inside an HTML table using TABLEDATA Function which does have an HTP equivalent in the TABLEDATA Procedure. The advantage of this using the FORMAT_CELL Function is that it allows for better control over the HTML tables.

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 data type 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 data type in the function.

Examples

The following commands 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 135-2 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

Syntax

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

Parameters

Table 135-3 ANCHOR Function Parameters

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

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

This function and the ANCHOR Function generate the <A> and </A> HTML tags which specify the source or destination of a hypertext link. The difference between these subprograms is that this functions provides a target and therefore can be used for a frame.

Syntax

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

Examples

This function generates

   cheight        IN       NUMBER,
   cwidth         IN       NUMBER,
   cattributes    IN       VARCHAR2   DEFAULT NULL)
  RETURN VARCHAR2;

Parameters

Table 135-5 APPLETOPEN Function Parameters

Parameter	Description
`ccode`	The the value for the `CODE` attribute which specifies the name of the applet class.
`cheight`	The value for the `HEIGHT` attribute.
`cwidth`	The value for the `WIDTH` attribute.
`cattributes`	The other attributes to be included as-is in the tag.

Examples

This function generates

<APPLET CODE=ccode HEIGHT=cheight WIDTH=cwidth cattributes>

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">

Usage Notes

Specify parameters to the Java applet using the PARAM Function function.
Use the cattributes parameter to specify the CODEBASE attribute since the PL/SQL cartridge does not know where to find the class files. The CODEBASE attribute specifies the virtual path containing the class files.

AREA Function

This function generates the <AREA> tag, which defines a client-side image map. The <AREA> tag defines areas within the image and destinations for the areas.

Syntax

HTF.AREA (
   ccoords        IN       VARCHAR2
   cshape         IN       VARCHAR2   DEFAULT NULL,
   chref          IN       VARCHAR2   DEFAULT NULL,

PRINT Functions

These functions generate the specified parameter as a string terminated with the \n newline character. The PRN Functions performs the same operation but does not terminate with a newline character.

Parameter	Description
`cbuf`	The string to generate terminated by a newline.
`dbuf`	The string to generate terminated by a newline.
`nbuf`	The string to generate terminated by a newline.
