javascript and rich:calendar

[daynol]

I can see the 1st (29/08/2010), 2nd(buscartarea), 4th(fecAsigDesde)   alert but 3rd shows me "seg1: undefined", I'd like have the value of fecAsigDesde, how could I do that? any idea plz?

Thx for advance

search.jspx
<h:form id="buscartarea">
            <h:panelGrid id="form_seg_tareas" columns="5">
                <h:outputLabel value="#{msg.label_tareas_fec_asig_desde}" styleClass="form-label" />
                <rich:calendar id="fecAsigDesde" value="#{TareasBean.busTarea.fecAsigDesde}" datePattern="dd/MM/yy" inputClass="form-input" />
                <rich:spacer width="20px" />
                <h:outputLabel value="#{msg.label_tareas_fec_asig_hasta}" styleClass="form-label" />
                <rich:calendar id="fecAsigHasta" value="#{TareasBean.busTarea.fecAsigHasta}" datePattern="dd/MM/yy" onchanged="compare(this.form,this,'fecAsigDesde');" inputClass="form-input" />

js.js

function compare(frm, pri, seg){
    alert('pri: ' + pri.value);
    alert('frm: ' + frm.name);
    
    var val2 = document.getElementById(frm.name+":fecAsigDesde").value;
    //var val2 = forms.elements[frm.name+":"+seg].value;
    alert('seg1: ' + val2);
    alert('seg: ' + seg);
    ///var val2 = document.forms[frm.name].elements[frm.name+":"+seg].value;
    ///alert('seg2: ' + val2);
    //var val2 = document.getElementById(frm.name+":fecAsigDesde");
    //alert("Value of xyz:" + val2.getProps().value);
    //alert('seg: ' + val2.getProps().value);

}

It will be easier to use our #{rich:component('calendarShortId')} and api to get current Value
