ZK 8 is moving to a next generation framework for application developer and web designer to cooperate with each other on a different aspect of the view while develop a webapp or website. The main feature of ZK 8 is to introduce a new '''Shadow Element''' concept, which is inspired from [http://w3c.github.io/webcomponents/spec/shadow/ Shadow DOM] to enable better composition of the ZK components and support with ZK DataBinding (MVVM) mechanism.

A shadow element is like a boilerplate template to help application developer to compose the html layout with some dynamic data, and the other hand the web designer can predefine the template or HTML page for application developer to use.

Before diving into the demo example, we will quickly introduce the new concept '''Shadow Element''' .
In fact, the shadow elements are not visible while application developer to manipulate ZK components tree as explaining below.

As the demo video, we designed the main view into 4 parts, ''Status'', ''Search Bar'', ''Switch Buttons'', and ''Data View Area'', and the designer can separately design the layout into a pure HTML if he like to. And the application developer can more focus on the business logical once the designed page is ready, they can simply use the shadow element with some condiction and data annotation (i.e. ZK MVVM).

In the zhtml page, the default page namespace is [http://books.zkoss.org/wiki/ZK_Component_Reference/XHTML_Components XHTML] which is used for dynamic data, and the other is [http://books.zkoss.org/wiki/ZUML_Reference/ZUML/Namespaces/Native Native] for static layout like line 1. Native component is transient alive in server side, so we cannot use it for data binding such as ''@load'', ''@bind'', ''@save'' expressions and the like. 
 +
 +
In the example above, we've used 3 new features of ZK 8:
 +
* Native component supports ''sclass'' attribute like ''class'' attributes e.g. line 4.

** ''c:cat3'' is an EL function, for more details please see [http://books.zkoss.org/wiki/ZUML_Reference/EL_Expressions/Core_Methods/cat3 here].

ZK8 Series: UI Template Injection

Version
ZK 8.0.0.FL.20150205
ZUTI 1.0.0.FL.20150205 (ZK UI Template Injection)

Introduction

ZK 8 is moving to a next generation framework for application developers and web designers to cooperate with each other on different aspects of the view while developing a web application or website. The main feature of ZK 8 is to introduce a new Shadow Element concept, which is inspired from Shadow DOM to enable better composition of ZK components and support the ZK DataBinding (MVVM) mechanism. In other words, ZK 8 is now even more effort-less when it comes to theming or styling customization. Application developers and/or web designers can now apply their own HTML based layout to coexist with ZK data driven power.

The built-in shadow elements are:

  • Apply: executable tags to allow you to choose which template is to be applied, it will lookup the template inside-out recursively.
  • ForEach: allows you to iterate over a collection of objects. Specifying the collection by using the items attribute, and the current item is available through a variable named by the var attribute.
  • Choose/When/Otherwise: performs conditional block execution by the embedded <when> subtags. It renders the body of the first <when> tag whose test condition evaluates to true. If none of the test conditions of nested <when> tags evaluate to true, then the body of an <otherwise> tag is evaluated, if present.
  • If: allows the conditional execution of its body according to the value of the test attribute.

Note: you can customize your own shadow elements if required.


Setup

Before using shadow elements, make sure you include the required jar - zuti.jar. With maven, you should add the dependency below:

    <dependency>
        <groupId>org.zkoss.zk</groupId>
        <artifactId>zuti</artifactId>
        <version>${zk.version}</version>
    </dependency>

Shadow Element Concept

Before diving into the demo example, we will quickly introduce the new concept Shadow Element . A shadow element is like a boilerplate code to help application developers to compose the html layout with some dynamic data. A web designer can pre-define a template based on HTML syntax for application developers to use. Technically, shadow elements are not visible while application developers manipulate ZK component's tree as explained below.

For example,

<div>
    <if test="${user.editable}">
        User Name: <textbox value="${user.name}"/>
        <forEach items="${user.phones}" var="phone">
            <label value="${phone.number}"/>
        </forEach>
    </if>
</div>

Shadow Diagram.PNG

As shown in the diagram above, the tree is separated into two parts - Logical Tree and Composed Tree.

  • Logical Tree is created by ZK page parser to construct a page definition tree and then instantiate it into a "Composed Tree".
  • Composed Tree is also separated into two parts, one is the component tree (green area) which is the same as before, and the other is the new concept (red area) shadow tree, which is not visible for application developers but component developers.

The shadow tree in the example above with EL expression won't be alive once the output is rendered to the client. This is because shadow elements are not applied with dynamic data such as @load expressions, so there is no reason to store them in the server side to burden the memory consumption.

Demo

In this demo, we will demonstrate how to layout 3 kinds of data views (grid, list, and tree) with the same data set and codebase.

  • [/_w/images/a/aa/2015-02-04_1629.swf for full size video]


There are three classes used in this demo, DataListViewModel, Item, and Author as illustrated below: ZK8 ZUTI Class Diagram.PNG

They work the same as POJO objects except for DataListViewModel in which it provides two commands doChangeMode() and doFilterItem() for the "View" to use.

Main Layout Design

In ZK 8, we enhanced the new HTML parser to make it work with HTML and XHTML structures seamlessly. As shown in the demo video, we designed the main view to have 4 parts - Status, Search Bar, Switch Buttons, and Data View Area. The designer can separately design the layout into a pure HTML if he/she prefers to while the application developer can focus more on the business logic. Once the designed page is ready, they can simply utilize the shadow element with data binding annotation (i.e. ZK MVVM). We will explain this later down the article.

Zk8 main design.PNG

Layout Injection Parts

The following fragment code we used is for the Data View Area to dynamically switch three kinds of view in less than 12 lines.

<div sclass="data-container">
	<choose>
		<when test="@load(vm.mode ne 'tree')">
			<forEach items="@load(vm.dataList)">
				<apply template="@load(vm.mode)" item="@ref(each)"/>
			</forEach>
		</when>
		<otherwise>
			<apply template="@load(vm.mode)" item="@ref(each)"/>
		</otherwise>
	</choose>
</div>

In this fragment code above, we use <choose>|<when>|<otherwise> tags (JSP-like) to switch the template with the new shadow element <apply> and you can declare which dynamic property you like to pass through into the applied template, like line 5 with item="@ref(each)" and then we can use the variable item in that template.

Grid View Template

We can also apply the template from another page, for example if it's a HTML based page (dataList_grid.zhtml).

	<template name="grid" src="/templates/dataList_grid.zhtml"/>

Note: you can also apply external template from <apply> shadow element directly. For example,

<apply templateURI="/templates/dataList_grid.zhtml"/>


Here is the content of the dataList_grid.zhtml file.

<div sclass="item mix" xmlns:n="native">
	<img sclass="center-block"
		src="@load(c:cat3('/image/Centigrade-Widget-Icons/' , each.name , '-128x128.png'))" />
	<n:div sclass="item-info">
		<n:div>
			<label sclass="item-name center-block" textContent="@load(each.name)" />
			<n:span style="text-align: left" sclass="pull-left">
				<img sclass="@load(c:cat('author-icon ', c:toLowerCase(each.author.name)))"
					src="~./img/spacer.gif" />
				<label textContent="@load(each.author.name)"
					sclass="author-name z-label" />
			</n:span>
		</n:div>
	</n:div>
</div>

In the zhtml page, the default page namespace is XHTML which is used for dynamic data, and the other is Native for static layout like line 1. Native component is transient alive in server side, so we cannot use it for data binding such as @load, @bind, @save expressions and the like.

In the example above, we've used 3 new features of ZK 8:

  • Native component supports sclass attribute like class attributes e.g. line 4.
  • XHTML component supports encoding url for src attribute like in line 3.
    • c:cat3 is an EL function, for more details please see here. In ZK 8, you can replace it with EL 3.0 string concatenation. (another new feature of ZK 8)
  • XHTML component supports textContent for data binding to apply text value like in line 6.

List View Template

<template name="list">
	<div sclass="item-list mix">
			<n:span sclass="item-thumb">
			<image sclass="item-icon" src="@load(c:cat3('/image/Centigrade-Widget-Icons/',
					 each.name , '-128x128.png'))" />
			</n:span>
			<n:span sclass="item-info">
				<label sclass="item-name" value="@load(each.name)" />
			</n:span>
			<span style="text-align: left" sclass="pull-right">
				<image
					sclass="@load(c:cat('author-icon ', c:toLowerCase(each.author.name)))" />
				<label value="@load(each.author.name)"
					sclass="author-name" />
			</span>
	</div>
</template>

As shown in the example above, the namespace with template list is ZUL. Because it is defined in index.zul, it will apply the same default namespace as the page definition. Like line 8,<label> is the ZUL component unlike in the grid view template where it is a XHTML component.

Tree View Template

In the tree view, we use two <forEach> with <if> to group the data items by author name illustrated in the highlighted lines below.

<template name="tree">
		<forEach items="@load(vm.authors)" var="author">
			<n:div sclass="mix" style="display:block">
				<span sclass="author-outline">
					<image
						sclass="@load(c:cat('author-icon ',
							c:toLowerCase(author.name)))" />
				</span>
				<label value="@load(author.name)"
					sclass="author-name" />
				<n:div sclass="item-tree-items">
					<n:div sclass="author-connector pull-left"/>
					<forEach items="@load(vm.dataList)" var="item">
						<if test="@load(item.author.name eq author.name)">
							<n:div sclass="pull-left">
								<n:span sclass="item-thumb">
									<image sclass="item-icon"
											src="@load(c:cat3('/image/Centigrade-Widget-Icons/',
												item.name , '-128x128.png'))" />
								</n:span>
								<n:span sclass="item-info">
									<label sclass="item-name" value="@load(item.name)" />
								</n:span>
							</n:div>
						</if>
					</forEach>
				</n:div>
			</n:div>
		</forEach>
		<if test="@load(not empty vm.authors)">
			<span sclass="author-outline author-empty"></span>
		</if>
</template>

More Advanced Usage

ZK 8 also provides some useful client side data binding API for application developers to use.

  • Command publish: There are two ways to publish a command from client to server.
    1. With native component or native namespace:
      <xhtml:button n:onClick="@command('doClick', {key:value, key1:value1})"/>
      The arguments of the command here is a JS code, unlike the @command annotation syntax with server side parameters.
    2. JS method invocation directly:
      wgt.$binder().command('doClick', args);
  • Command subscribe:
    wgt.$binder().after('commandName', callbackFuncation);

As the example shown below, we apply a MinItUp animation with our demo case after both commands "changeMode" and "filter" are triggered. (line 21)

zk.afterMount(function(){

	// Instantiate MixItUp:
	$('.data-container').mixItUp({layout:{display: 'block'}});
	
	// get the current widget from the given selector.
	var wgt = zk.$('.data-container'); // the shortcut 'zk.$()' supported since ZK 8.0.0
	
	// get the current binder
	var binder = wgt.$binder(); // you can use the shortcut as well. zkbind.$('.data-container')

	// define the animation function
	var anima = function () {
		if (wgt.firstChild && jq(wgt.firstChild).hasClass('mix')) {
			$('.data-container').data('mixItUp').sort('random');
		}
	};
	anima();
	
	// do the animation function after both commands 'changeMode' and 'filter'
	binder.after('changeMode', anima).after('filter', anima);
});

Summary

In ZK 8, we introduce a more easy, clever, and powerful way to seamlessly coexist with the world's hottest HTML5. With ZK 8, application developers can do effortless theming and styling customization based on each application requirement while the web designer can focus on designing fashionable layouts without having to understand ZK Components or technology. We'd also appreciate any feedback on your thoughts and ideas regarding the new ZK 8 concept!
