页面代码：

@{ViewBag.Title = "Index";
}<h2>全圆园 666</h2>
<div class="input-group"><label>名称：</label><input type="text" class="form-control" id="txtCondName" value="@ViewBag.name"/><input type="button" id="btnSearch" value="搜索" onclick="page(1);" />
</div>
<table class="table table-bordered"><thead><tr><th>编号</th><th>名称</th><th>备注</th></tr></thead><tbody>@foreach (var item in Model){<tr><th>@item.ID</th><th>@item.Name</th><th>@item.Remark</th></tr>}</tbody></table><nav aria-label="..."><ul class="pagination"><li class="page-item ">共 @ViewBag.totalPages 页，第<input type="number" min="1" max="@ViewBag.totalPages" id="pageIndex" value="@ViewBag.pageIndex" />页，每页显示<select id="pageSize" onchange="page(1);">@{var listPageSize = new List<int> { 5, 10, 20, 50, 100 };}@foreach (var item in listPageSize){if (@ViewBag.pageSize == @item){<option value="@item" selected="selected">@item</option>}else{<option value="@item">@item</option>}}</select>条</li></ul><ul class="pagination"><li class="page-item "><a class="page-link" href="javascript:page(1);" tabindex="-1" aria-disabled="true">首页</a></li>@if (@ViewBag.pageIndex > 1){<li class="page-item"><a class="page-link" href="javascript:page(@ViewBag.pageIndex-1);">上页</a></li>}else{<li class="page-item disabled"><a class="page-link" href="javascript:page(@ViewBag.pageIndex-1);">上页</a></li>}<li class="page-item " aria-current="page"><span class="page-link"> @ViewBag.pageIndex</span></li>@if (@ViewBag.pageIndex < @ViewBag.totalPages){<li class="page-item " aria-current="page"><a class="page-link" href="javascript:page(@ViewBag.pageIndex+1);">下页 </a></li>}else{<li class="page-item disabled" aria-current="page"><a class="page-link" href="javascript:page(@ViewBag.pageIndex+1);">下页 </a></li>}<li class="page-item"><a class="page-link" href="javascript:page(@ViewBag.totalPages);">末页</a></li><li class="page-item"><input type="button" class="page-link" value="GO" onclick="go()" /></li></ul>
</nav>@section scripts{<script>function page(pageIndex) {var name = $("#txtCondName").val(); //获取搜索框的值var pageSize = $("#pageSize").val(); //获取下拉框的值window.location.href = "/role/index?pageindex=" + pageIndex+ "&pageSize=" + pageSize + "&name=" + name;}function go() {//获取输入的页码的值var pageIndex = $("#pageIndex").val();page(pageIndex);}</script>}

控制器代码：

 public ActionResult Index(int pageIndex=1,int pageSize=10,string name=""){//获取总记录数var totalRows = db.Roles.Count();//计算总页数var totalPages = Math.Ceiling(totalRows * 1.00 / pageSize);ViewBag.totalPages = totalPages;var roles = db.Roles.Where(p=>p.Name.Contains(name)).OrderBy(p=>p.ID)  //排序.Skip((pageIndex-1) * pageSize)    //跳过.Take(pageSize)   //取.ToList();ViewBag.pageIndex = pageIndex;ViewBag.name = name;ViewBag.pageSize = pageSize;return View(roles);}

总结：

1. 如果页面刷新但不重置已设置值，可以用ViewBag实现值复用。
2. 页面用脚本定义方法实现跳转的代码量远比直接写链接传值代码量小。
3. 可以使用数组对pageSize的值实现循环判断且效率较高。
