Why my page can't redirect under Struts with Javascript?

Question

I use Javascript in Struts,like follows:
<script language="JavaScript">
<!--
function goURL(tmp){
alert(tmp);
document.forms[0].action="/log.do?action="+eval(tmp);
document.forms[0].submit();
-->
</script>     
<html:form method="post" action="log.do">
<html:link page="/log.do?action=First">First Page</html:link>
<html:select property="pageID" size="1" onchange="javascript:goURL(this.options[this.selectedIndex].value)">
<option value="0">First</option>     
<option value="1">Second</option>
<option value="2">Third</option>     
</html:select>
</html:form>when click "First Page",I can redirect my page to log.do page,but when I change the value of select,I find my page don't redirect to the log.do page,why? I am puzzled with it! Anybody can tell me how to redirect my page with Javascript under Struts?
Thanks

Except for naming your function onEnterFrame (an AS2 term), the code works okay.
