Component

Syntax

<zk:component name="componentName" [class="myPackage.myClass"]
    [extends="existentJavaClassName"] [moldName="myMoldName"] [moldURI="myMoldURI"]
    [prop1="value1"] [prop2="value2"].../>

It defines a new kind of component tag, which could be used in the JSP document. If the class attribute is declared, the class must implement Component.

Inline Macro Definition

Syntax

<zk:component name="componentName" macroURI="/mypath/my.zul" inline="true"
 [prop1="value1"] [prop2="value2"].../>

By specifying inline="true", we could define an inline macro which will inline-expends the macro template (specified in macroURI) when it is used. In other words, it works as if you copy the content from the template directly to the target document.

Use New Defined Components

Due to the limitation of JSP, we cannot declare a new JSP tag dynamically. In other words, we can not specify the name of the new defined component directly. Thus, we introduce a special tag called ui that has a special attribute called tag to allow us to specify the component's name. For example:

<zk:component name="username" inline="true" macroURI="/macro/username.zul">
...
<zk:page>
  <zk:ui tag="username" who="ZK User"/>
    
</zk:page>

As shown, the tag attribute specifies the name of the component defined in this JSP document.
