<a href="javascript:gotoPage(<%=pageNo+1 %>)?page=<%=pageNo %>" >下一页</a>&nbsp;

<a href="javascript:gotoPage('<%=pageNo %>')" >下一页</a>&nbsp;

function gotoPage(pageNo){
   var url = "XX.do?page=pageNo+1";
   ...
}

------解决方案--------------------
HTML code


<a href="javascript:gotoPage(<%=pageNo+1 %>)?page=<%=pageNo %>" >下一页</a>&nbsp;

LZ的gotoPage()?page
js里面好像没有方法带参数的吧。

<a href="javascript:gotoPage(<%=pageNo+1%>)" >下一页</a>
function gotoPage(){
  ...
}
