MvcPager 分页示例 — Javascript API操作AjaxPager

本示例演示如何使用客户端Javascript API的goToPage方法来使AjaxPager跳转到指定页。

使用Javascript API操作MvcPager时,必须用Html.RegisterMvcPagerScriptResource()注册MvcPager的客户端脚本库。

goToPage方法在跳转前会对传入的页索引参数进行有效性验证,如果传入的页索引不是有效的数值或页索引超出范围(小于0或大于总页数),则会触发PagerOptions.OnPageIndexError属性指定的Javascript函数。可以在本示例中输入进行测试查看效果。
