[TYPO3-realty] Realty Objects - add new fields

[Ada Borlovan]

Can you please give me a concret example?
When the first value in listbox is selected I want to hide all the fields
upon the class .example
So I guess that I need the selectedIndex from the listbox.
And then to make a switch. My problem is that I don't know how to get the
selecteditem.

This is what I have added in tx_realty_frontEndEditor.xml
<renderlet:LISTBOX name="immotyp"
label="LLL:EXT:realty_ext/locallang_db.xml:tx_realty_objects.immotyp">
			<data>
				<items>
					<item>
	
<caption>LLL:EXT:realty_ext/locallang_db.xml:tx_realty_objects.immotyp.I.0</
caption>
						<value>0</value>
					</item>
					<item>
	
<caption>LLL:EXT:realty_ext/locallang_db.xml:tx_realty_objects.immotyp.I.1</
caption>
						<value>1</value>
					</item>
					<item>
	
<caption>LLL:EXT:realty_ext/locallang_db.xml:tx_realty_objects.immotyp.I.2</
caption>
						<value>2</value>
					</item>
				</items>
			</data>
			<validators>
				<validator:STANDARD>
					<userobj>
						<extension>this</extension>
	
<method>isIntegerInRange</method>
						<params>
							<data name="range"
value="0-2"/>
							<data
name="multiple" value="0"/>
						</params>
						<message>
							<userobj>
	
<extension>this</extension>
	
<method>getValueNotAllowedMessage</method>
								<params>
	
<data name="fieldName" value="immotyp"/>
								</params>
							</userobj>
						</message>
					</userobj>
				</validator:STANDARD>
			</validators>
			<onclick>updateHideAndShow();</onclick>
		</renderlet:LISTBOX>

And in function updateShowandHide

switch ($("tx_realty_frontEndEditor_immotyp_item").selectedindex) {
		case 0: 	$$(".gewerbeimmo").invoke("show");
					$$(".wohnimmo").invoke("hide");
					$$(".unbebaut").invoke("hide");
                    break;
 
		case 1: 	$$(".gewerbeimmo").invoke("hide");
					$$(".wohnimmo").invoke("show");
					$$(".unbebaut").invoke("hide");
                    break;
 
		case 2: 	$$(".gewerbeimmo").invoke("hide");
					$$(".wohnimmo").invoke("hide");
					$$(".unbebaut").invoke("show");
                    break;
  }

What I make wrong? Give me please an advise how to do better.

Indeed, you'll need to change/enhance the JavaScript function
updateHideAndShow.

This isn't particularly TYPO3-specific - it's just modifying the DOM
using Prototype's functions depending on the values of some form fields.
