36 | /** | |
37 | * Template context tool that can be used to set various attributes of a | |
38 | * HTML page. This tool does not automatically make the changes in the HTML | |
39 | * page for you. You must use this tool in your layout template to retrieve | |
40 | * the attributes. | |
41 | * <p> | |
42 | * The set/add methods are can be used from a screen template, action, screen | |
43 | * class, layour template, or anywhere else. The get methods should be used in | |
44 | * your layout template(s) to construct the appropriate HTML tags. | |
45 | *<p> | |
46 | * Example usage of this tool to build the HEAD and BODY tags in your layout | |
47 | * templates: | |
48 | * <p> | |
49 | * <code> | |
50 | * ## Set defaults for all pages using this layout. Anything set here can<br> | |
51 | * ## be overridden in the screen template.<br> | |
52 | * $page.setTitle("My default page title");<br> | |
53 | * $page.setHttpEquiv("Content-Style-Type","text/css")<br> | |
54 | * $page.addStyleSheet($content.getURI("myStyleSheet.css"))<br> | |
55 | * $page.addScript($content.getURI("globalJavascriptCode.js"))<br> | |
56 | * <br> | |
57 | * ## build the HTML, HEAD, and BODY tags dynamically<br> | |
58 | * <html><br> | |
59 | * <head><br> | |
60 | * #if( $page.Title != "" )<br> | |
