java.lang.Object
  org.apache.hivemind.impl.BaseLocatable
      org.apache.tapestry.AbstractComponent
          net.sf.tacos.components.ClientLink

All Implemented Interfaces:

Locatable, LocationHolder, org.apache.tapestry.IComponent, org.apache.tapestry.IDirect, org.apache.tapestry.IDirectEvent, org.apache.tapestry.IDynamicInvoker, org.apache.tapestry.internal.Component, org.apache.tapestry.IRender

public abstract class ClientLink
extends org.apache.tapestry.AbstractComponent
implements org.apache.tapestry.IDirect

A component for creating a javascript function whose body is a call of an url definied by the direct service. This component is similar to DirectLink component but allows you to call listener methods from javascript code without to click on any link or button.

The required parameters are: a listener method and the name of the function to generate.

<span jwcid="@tacos:ClientLink" listener="listener:onClick" function="myFunction"/>

The generated function can be used like this:

function test(){
        ...
        myFunction();
}
