Sample for JavaScript DHTML Functions

ProcedureTo Use the JavaScript DHTML Functions Sample

  1. This sample can be accessed from:

    portal-server-URL/rewriter/JavaScript/functions/dhtml/dhtml.html

  2. Add the rule specified in this sample (if it does not already exist) to the default_gateway_ruleset in the section "Rules for Rewriting JavaScript Source".

  3. Edit the default_gateway_ruleset in the Rewriter service under Portal Server Configuration in the Portal Server administration console.

  4. Restart the Gateway:


    ./psadmin start-sra-instance –u amadmin – f  <password file> –N <profile name>– t  <gateway>

<!--
document.write(\q<a href="gateway-URL
/portal-server-URL/index.html">write</a><BR>\q)

// The first rule specifies that the first parameter of the DHTML JavaScript function document.write needs to be rewritten. Rewriter identifies the first parameter to be a simple HTML statement. The HTML rules section in the default_gateway_ruleset has the rule <Attribute name="href" /> which indicates that the statement needs to be rewritten.

document.writeln(\q<a href="gateway-URL
/portal-server-URL/rewriter/JavaScript/functions/dhtml/index.html">writeln</a><BR>\q)

// The second rule specifies that the first parameter of the DHTML JavaScript function document.writeln needs to be rewritten. Rewriter identifies the first parameter to be a simple HTML statement. The HTML rules section in the default_gateway_ruleset has the rule <Attribute name="href" /> which indicates that the statement needs to be rewritten.

document.write("http://abc.sesta.com/index.html<BR>")
document.writeln("http://abc.sesta.com/index.html<BR>")

// The above statements are not rewritten although the DHTML rule identifies the functions document.write and document.writeln. This is because the first parameter in this case is not simple HTML. It could be any string, and Rewriter does not know how to rewrite this.
