使用MVCPager做AJAX分页所走的弯路

使用MVCPager做AJAX分页所需要注意的地方：

1.测试版本MvcPager-3.0.1

2.当需要使用页索引输入或下拉框以及使用Ajax分页模式时，必须用Html.RegisterMvcPagerScriptResource方法注册MvcPager客户端jQuery插件，不注册此插件则选择或输入页索引后将无法跳转，Ajax功能也无法正常运行。  

具体代码：@{Html.RegisterMvcPagerScriptResource();}  注：在view中加

3.一定要引用jquery.unobtrusive-ajax.min.js 这个JS插件

4.如果要更新部分页面，一定要把子页面的Model放到父页面的Model中传过去，不能使用html.action然后子页面去请求自己的数据这种方式。这点要切记啊！


5.也是致命的一点：分页条里面指定的UpdateTargetId 一定要是分页条的父级节点，而不能同级，反正我尝试的时候是这样子。


6.分页条写法：

@Ajax.Pager(Model, new PagerOptions { ShowPageIndexBox = true, PageIndexBoxType = PageIndexBoxType.TextBox, ShowGoButton = true }, new MvcAjaxOptions { UpdateTargetId = "Review", EnablePartialLoading = true })
