Added Groovy example integrated on ItsNat in ItsNat Experiments

[Jose Maria Arranz Santamaria]

This example shows how we can use a dynamic language like Groovy to code the view logic of an ItsNat application instead of using Java.

Your ItsNat code will be similar to this:

package inexp.groovyex;

import org.w3c.dom.events.Event

import org.w3c.dom.events.EventListener

class GroovyExampleDocument

{

    def itsNatDoc // ItsNatHTMLDocument

    def textInput // ItsNatHTMLInputText

    def resultsElem // Element   

    GroovyExampleDocument(itsNatDoc)

    {

        this.itsNatDoc = itsNatDoc

        def doc = itsNatDoc.getHTMLDocument()

   

        def compMgr = itsNatDoc.getItsNatComponentManager()

        this.textInput = compMgr.createItsNatComponentById("inputId")

        

        def buttonElem = doc.getElementById("buttonId")

        buttonElem.addEventListener("click", 

             { Event evt -> def text = textInput.getText(); resultsElem.setTextContent(text); } as EventListener, false)

        this.resultsElem = doc.getElementById("resultsId")

    }

}

Unfortunately hot redeploy doesn't work because Groovy objects (listeners) are registered in and called by ItsNat Java classes, after any change to Groovy code you must redeploy the web app to make effective your changes.

See online and Source code (groovyex folders)

Enjoy.
