Highlighted Features

Data Binding Syntax Sugar

ZK supports a simplified syntax with a built-in convention. You can type fewer characters without an annotation name.

Default ViewModel ID

Default ViewModel ID is vm without explicitly specified.

<!-- original syntax -->
<div viewModel="@id('vm') @init('MyViewModel')" >

<!-- new syntax -->
<div viewModel="@('MyViewModel')">

Auto ViewModel Lookup

By default, ZK looks for a ViewModel in the same ID space.

<!-- original syntax -->
<label value="@load(vm.aaa)"/>

<!-- new syntax -->
<label value="@load(aaa)"/>

Auto Binding Name Mapping

<!-- original syntax -->


<!-- new syntax -->
@load(vm.aaa) -> @(aaa)
@bind(vm.aaa) -> @(aaa)  //auto bind in input element
@commnad('cmd') -> @('cmd') //auto bind in event (ex. onClick, onXxx...)

Theme template supports compact themes

ZK Theme Template provides an easy way for theme customization. It is now updated to support compact themes — you can now customize a compact theme (ex. iceblue_c) as easy as the standard themes, and upgrade the theme easily when you upgrade your ZK version.

Backward compatibility: ZK 7 form binding

In ZK 8 a new MVVM form binding was introduced which made it difficult for ZK 7 projects to upgrade. In ZK 9.5 we have now ported back ZK 7’s simple form binding. If you have ZK 7 projects that use the legacy simple form binding, you can easily upgrade to ZK 9.5 with minimum code changes.
