<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <p:selectonemenu id="onemenu1" required="true" styleclass="vehavailclass" requiredmessage="#{itrams['refreshratereq']}" editable="true" style="width:100px" value="#{dashboardaction.selectrefreshrate}">   <f:selectitem itemlabel="#{dashboardaction.vehicleavail}" itemvalue="#{dashboardaction.vehicleavail}" />   <f:selectitems value="#{dashboardaction.getrrlist()}" /> </p:selectonemenu>  <!-- jira 741 start  -->  <p:selectonemenu id="secsdropdown" required="true" value="#{dashboardaction.unitofrefreshrate}" style="width:70px">   <f:selectitems value="#{dashboardaction.getrrunitlist()}" /> </p:selectonemenu>

you need use .prop() method , better go class instead: 

$('.vehavailclass').change(function() {     $(this).next('select').prop('disabled', this.value === 'never');  });                                      // this.value === 'never'                                          // results in true/false

if have select elements in form have notice id has been changed in manner formid:selectid. so, in case might yourformid:onemenu1.

updates: 

$('#dashboardformid\\:onemenu1').change(function() {     $('#dashboardformid\\:secsdropdown').prop('disabled', this.value === 'never');  });

here have escape :.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
