需要在jsf </f：ajax>中的<f：ajax>响应上调用javascript文件

Question

实际上当我的回复来的时候我试着调用javascript文件。在我的代码中，我有切换按钮和两个div是隐藏并显示相应的切换按钮值更改。但是当第二个div显示时，想要每次调用javascript文件ajax电话。

<div class="form-group">
   <h:outputLabel  class="col-lg-4 control-label" value="Apply on Company"></h:outputLabel>
  <div class="col-lg-5">
     <div class="left marginR10">
       <div class="normal-toggle-button toggle-custom-size">
           <h:selectBooleanCheckbox class="nostyle" value="#{promocdbean.aplyOnCmpny}">
              <f:ajax execute="@this" event="change" render="prefbyselection" />
           </h:selectBooleanCheckbox>   
      </div>
      </div>
      </div>
   </div>  <!-- End .form-group  -->
   <h:panelGroup id="prefbyselection" layout="block" >
     <h:panelGroup id="cmpnynm" layout="block" class="form-group" rendered="#{promocdbean.aplyOnCmpny }">
    <h:outputLabel for="cmpnyname" class="col-lg-4 control-label" value="Company Name" ></h:outputLabel>
    <div class="col-lg-6">
     <h:outputLabel  class="control-label"  value="Nirula'a Corner House Private Limited" ></h:outputLabel>
    </div>
    </h:panelGroup>
    <h:panelGroup id="locatn" layout="block" class="form-group" rendered="#{!promocdbean.aplyOnCmpny}" >
       <h:outputLabel for="location" class="col-lg-4 control-label" value="Location" onfocus="loadScript()"></h:outputLabel>
         <div class="col-lg-5" >
            <h:selectOneMenu id="location"  value="#{promocdbean.location}" class="form-control" >
                 <f:selectItem itemValue="77" itemLabel="Nirulas (Preet Vihar)"></f:selectItem>
                <f:selectItem itemValue="76" itemLabel="Nirulas (19 Community center)"></f:selectItem>
         </h:selectOneMenu>
       </div>
    </h:panelGroup>
 </h:panelGroup>
