function batchdel() {//批量删除
        var chk_value =[]; 
            $('input[name="ids"]:checked').each(function(){ 
                chk_value.push($(this).val());
            });
            if (chk_value.length==0) {
                alert("请选择学号！");
                return false;
            }
            if (chk_value.length > 0) {
                var msg = '确认删除' + chk_value + '吗？';
                if (confirm(msg) == true) {
                    location.href = "<%=basePath%>user/batchDelete?chk_value=" + chk_value;
                    return true;

        var arr = obj.split(",");
        var i = arr.length;
        while (i--) {
            if (arr[i] == ele) {
                return true;  
            }  
        }  
        return false;  
    }

<a href="list?pageIndex=${pageUtil.pageIndex<pageUtil.pageCount?pageUtil.pageIndex+1:pageUtil.pageCount}" class='next' onclick="changeIds();getChecked();contains(this,obj,ele);">下一页</a>

Answer 1

changeIds 这方法调用了?
oneches[i].value log一下 看看有值么?

Answer 2

楼主，将当前页保存的 id，保存在 sessionStorage 或者 cookie 里，是可以的
