function selflog_show(id)为什么就是调用不了~~
<script type="text/javascript">
function selflog_show(id)
{
alter(id);
var num = document.getElementById("number").value;
alter(num);
J.dialog.get({id: 'haoyue_creat',title: '购物成功',width: 600,height:400, link: '<%=path%>/servlet/CartServlet?id='+id+'&num='+num+'&action=add', cover:true});
}
</script>
