我的分页工具栏有问题。 我想给用户提供设置每页结果数（限制）的选项。我有一个下拉菜单。 我已将页面大小初始化为20。 当我从下拉列表中设置我的限制（例如50）时，n假设我得到90个结果，所以在第一页上它正确显示1-50个结果，但是在下一页上它显示的结果是21-70而不是51-90 。 因此，我无法根据下拉列表设置的限制重置页面大小。开始总是拿起初始化的页面大小。 有什么建议？ 我附上我的代码......

答案 0 :(得分：0)
尝试在商店中使用extraParams。
this.store.getProxy().extraParams = { start: 0, limit: this.pageSize};
this.store.load();
