how come jquery(or ajax) removed javascript from a remote server?


when I use $("#selectableServiceLevelListContainer").load(requestUrl +
" #getServiceListResult", hwFamilyCodes) to get the returned html and
javascript.
html content can be returned correctly, but javascript is removed by
jquery or ajax, I am not sure what caused this problem.
any one can give me some advice?
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<div id="getServiceListResult">
hello
<script type="text/javascript">
pspList= ${pspSearchResultList};
</script>
world
</div>
i tried to use alert("have a nice day"); this is removed too without
any warning alert.
only "hello world" is displayed. and the source code of the page did
not have expected javascript.
