HTML Template Direct Access Context

Every SBM browser page is generated from an HTML template containing HTML and proprietary server-side instructions. If an HTML template contains the server-side instruction $SCRIPT(), with proper parameters, the server runs the specified script. In the outgoing HTML, the entire $SCRIPT instruction is replaced by the script's output. If the script's output is valid HTML, it is visible in the browser. For an example of $SCRIPT() usage, see below.

To view an HTML template, browse to an SBM URL containing the parameter "Template=name", where "name" is the file name of the template, excluding the "htm" extension. For example, the URL for the About page is as follows:


If the HTML template contains a $SCRIPT tag, the output of that script is visible on the page.

Any optional parameters following the name/ID are inserted into a Dictionary object which is passed to the script. The Dictionary of optional parameters is accessible from within the script as "Shell.Params()." Shell.Params() supports the methods and properties of a Dictionary.

The value of the Nth optional parameter is associated with a key called "paramN." For example, the first optional parameter is "param1."

Example: Using $SCRIPT() in HTML

Create a script called myScript:

var sText1;
var sText2;
Shell.Params().Item( "param1" );
Shell.Params().Item( "param2" );

Ext.WriteStream( "<HTML>");
Ext.WriteStream( "<HEAD><TITLE>Script Test</TITLE></HEAD>" );
Ext.WriteStream( "<BODY>" );

Ext.WriteStream( "Param1: " );
Ext.WriteStream( "<H2>" &&& EncodeHTML(sText1) &&& "</H2>" );
Ext.WriteStream( "<BR>" );

Ext.WriteStream( "Param2: " );
Ext.WriteStream( "<H2>" &&& EncodeHTML(sText2) &&& "</H2>" );
Ext.WriteStream( "<BR>" );

Ext.WriteStream( "</BODY>" );
Ext.WriteStream( "</HTML>" );

Create an HTML file called scripttest.htm, and add the following text to it:

$SCRIPT( myScript, Godzilla, King Kong );

Save this file in the SBM installation templates directory.

Use the following URL to test the $SCRIPT mechanism:
