点下一页的时候不起作用~~将页面中的开头索引参数传递给action，js这样写对不对？
function goPage(page){
if(page < 1 || (page > totalPageCount && page != 1)){
return;
}
var obj = document.getElementById("ec");
obj.action = "/imanager/usermanager/userIndex.action";
$("curPageNo").value = page;
$("startIndex").value = (page-1)*20;
obj.submit();
}
页面中的：
<input type="hidden" id="curPageNo" value="<ww:property value="pager.pageNo"/>"/>
<input type="hidden" id="startIndex" value="<ww:property value="startIndex"/>"/>
function goPage(page){
if(page < 1 || (page > totalPageCount && page != 1)){
return;
}
var obj = document.getElementById("ec");
obj.action = "/imanager/usermanager/userIndex.action";
$("curPageNo").value = page;
$("startIndex").value = (page-1)*20;
obj.submit();
}
页面中的：
<input type="hidden" id="curPageNo" value="<ww:property value="pager.pageNo"/>"/>
<input type="hidden" id="startIndex" value="<ww:property value="startIndex"/>"/>

pageCount一页显示几条记录

现在的问题是为什么jsp页面无法取到action中的变量值啊 set get方法都有的
