javascript - Get node inside template if statement -

-

on polymer-based website created custom element in loading data via ajax. depending on current state of data-loading created <template if="{{}}"> elements display right content. looks way:

<polymer-element name="modules-item" attributes="moduleid categories">   <template >     <service-get-module module="{{module}}" moduleid="{{moduleid}}"></service-get-module>     <paper-shadow z="1">         <core-toolbar>           <span flex  hero-id="title" hero itemprop="name">{{module.title}}</span>         </core-toolbar>     </paper-shadow>     <paper-progress id="moduleloadingprogress"></paper-progress>     <template if="{{moduleid == null}}">         <p>modul not available</p>     </template>     <template if="{{moduleid != null && module == null}}">         <p>module loading...</p>     </template>     <template if="{{moduleid != null && module != null}}">         <div id="modulecontainer">         <!-- content //-->         </div>    <template>  </template> <script>   polymer({     module: null,     moduleid: null,     ready: function(){         console.log(this.$.modulecontainer);     } </script> </polymer-element>

that works great, if try access <div id="modulecontainer"> don't it... read many posts did not solution. may anybode me? :)

update

after working little longer polymer found out, it's easier use hidden?-attribute, casual hide content. example:

<div hidden?="{{moduleid != null}}">module not available</div>

you can't access elements within <template if="{{..}}"> or <template repeat="{{..}}"> (dynamically created) using $ accessor. need use queryselector(...) , can field when if expression evaluates true (the element created/shown)
