[JIRA] Commented: (CLK-501) Add first class support for HTML Head resources such as Javascript and CSS

    [ http://issues.apache.org/click/browse/CLK-501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=11724#action_11724 ] 

Malcolm Edgar commented on CLK-501:
-----------------------------------

In terms of a design we could introduce a HTML Element class which can be used for:
* TitleElement
* CssStyleElement
* CssImportElement
* JsScriptElement
* JsImportElement

A Page could expose the methods:

List<Element> getHeadElements()

List<Element> getJsElements()

In the page template users would do something like:
<html>
<head>
#foreach ($element in $headElements)
$element
#end
</head>
<body>

<body>
#foreach ($element in $jsElements)
$element
#end

>
> Currently Click supports HTML imports by overriding the method #getHtmlImports. 
> This method is string based which makes it difficult to support advanced features such as templating, conditional imports, resource versioning etc.
> This feature request proposes to introduce first class HTML header resource classes including Javascript, JavascriptImport, CssImport and Css.
> Further a new method should be added to the Control interface: 'public List getHtmlHeaders' which returns a list of the Page or Control's HTML HEAD entries.
> This makes it possible to modify the Javascript and CSS imports without overriding a Control.
