I've been wondering about AngularJS, the framework for HTML.
Interestingly, XUL (XML User Interface Language) and HTML share similar underlying processing abilities, as both can utilize JavaScript and CSS.
Is it possible for AngularJS to integrate with XUL?
In order for AngularJS syntax to work with XUL, it needs to comply with XML standards:
Include id="ng-app" in the root element along with the ng-app attribute
<!doctype html>
<html xmlns:ng="urn:ng" id="ng-app" ng:app="optionalModuleName">
<div my-directive="exp"></div>
...
</html>
Utilize custom element tags like <ng:view>
To ensure CSS selectors work with custom elements, create the custom element name using document.createElement('my-tag') without considering the XML namespace.
<html xmlns:ng="urn:ng">
<!-- Needed for ng namespace -->
<head>
<!--[if lte IE 8]>
<script>
// needed to allow ng-include to parse correctly
document.createElement('ng-include');
// needed to enable CSS reference
document.createElement('ng:view');
</script>
<![endif]-->
<style>
ng\:view {
display: block;
border: 1px solid red;
}
ng\:include {
display: block;
border: 1px solid blue;
}
</style>
</head>
<body>
<ng:view></ng:view>
<ng:include></ng:include>
...
</body>
</html>
The compiler now supports multiple directive syntaxes transparently. For instance, previously there was only one way to use the ng:include directive. The new compiler treats all of the following as equal:
<ng:include src="someSrc"></ng:include> <!-- XHTML element-->
<div ng:include src="someSrc"></div><!-- XHTML attribute-->
<div ng:include="someSrc"></div><!-- XHTML attribute shorthand -->
<div data-ng-include src="someSrc"></div><!-- data attribute-->
<div data-ng-include="someSrc"></div><!-- data attribute shorthand-->
<ng-include src="someSrc"></ng-include> <!-- Expando Element -->
<div ng-include src="someSrc"></div><!-- Expando Attribute-->
<div ng-include="someSrc"></div><!-- Expando attribute shorthand-->
<x-ng-include src="someSrc"></x-ng-include> <!-- Mozilla X-Tag -->
<div class="ng-include: someSrc"></div><!-- Class property-->
This allows template creators to choose between HTML code validity and conciseness, picking the syntax that suits them best.
