I'm using a layout where a number of javascript libraries are included at the bottom the file, just above the close of the body tag. What I want to do is add some custom javascript below them on various pages but not all pages. Is there some equivalent of
<g:render template="customjs"/>
I can use in the layout gsp that only renders the template if it exists and does not crash on pages without the _customjs.gsp?

If your controller name is "MyJsController"
Consider wrapping this code into a TagLib for better reuse
<g:set var="controller" value="myJs" />
<g:set var="template" value="customjs" />
<g:set var="patternResolver" value="${new org.springframework.core.io.support.PathMatchingResourcePatternResolver()}" />
<g:set var="pathPattern" value="grails-app/views/${controller}/_${template}.gsp" />
<g:if test="${patternResolver.getResources(pathPattern)}">
<g:render template="/${controller}/${template}" />
</g:if><g:else>
not found!
</g:else>
