Multiple including javascript libs poroblem

Hey friends
I use this method for including a javascript library into my portlet :


<script>
        Liferay.Loader.define._amd = Liferay.Loader.define.amd;
        Liferay.Loader.define.amd = false;
    </script>
&nbsp; &nbsp; <script type="text/javascript" src="<%=request.getContextPath()%>/js/highcharts.js"  ></script>
&nbsp; &nbsp; <script>
        Liferay.Loader.define.amd = Liferay.Loader.define._amd;
    </script>
&nbsp; &nbsp;

It works correctly if only there is one instance in a page, But for more instance , other instances not return error
How can I prevent including multiple time?

You'll declare it in your portlet's header as one of these:

com.liferay.portlet.header-portlet-javascript

com.liferay.portlet.footer-portlet-javascript
