How to use rich:pickList by JavaScript in order to know which item is selected?

[ealonso04]

Hi guys!

I need to know how to use the functions or properties of the rich:pickList by Javascript. I need to disabled the remove button when I select or click a certain element or item in the target list.

I have looked for information in Internet without success. I hope somebody could help me with this.

Thanks in advance!

Regards!

Hi!

I can get the String of the item selected in the target list by calling a javaScript function like this:

pickList.xhtml:

<rich:pickList value="#{workListBean.selectedColumns}" sourceCaption="Columnas disponibles" targetCaption="Lista de Trabajo"

               listWidth="165px" listHeight="100px" orderable="true" switchByDblClick="true"

               style="text-align: left;"

               id="pick" ontargetclick="test(event);">

     <f:selectItems value="#{workListBean.availableColumns}" var="column" itemValue="#{column}" itemLabel="#{column.label}" />

     <f:converter converterId="ColumnsConverter" />

</rich:pickList>

JavaScript function:

function test(event){

    alert(event.target.textContent);

}

But how can I disable the remove button from the pickList?

I have another post asking for that: https://community.jboss.org/thread/203011?tstart=30
