如何在 Asp.net MVC 4 中使用 Simple Ajax Beginform? [英] How to use Simple Ajax Beginform in Asp.net MVC 4?

问题描述

我是 Asp.net MVC 的新手，我研究了 Ajax.BeginForm 但是当我应用代码时它不起作用.你能用 Ajax.Beginform 和视图、控制器、模型分享非常简单的例子吗?谢谢.

解决方案

简单示例:带有文本框和搜索按钮的表单.

如果您在textbox中输入姓名"并提交表格，它会在表格中为您带来带有姓名"的患者.

查看:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients 是 PatientController 中的方法名InsertionMode = InsertionMode.Replace,//目标元素(#patientList)将被替换UpdateTargetId = "患者名单",LoadingElementId = "loader"//带有 .gif 加载器的 div - 在加载数据时显示})){字符串患者姓名 = "";@Html.EditorFor(x=>patient_Name)//带有名称和ID的文本框，它将传递给控制器<input type="submit" value="搜索"/>}@* ... *@<div id="loader" class="alert" style="display:none">正在加载...<img src="~/Images/ajax-loader.gif"/>

@Html.Partial("_patientList") @* 这是带有患者表的视图.您将从控制器返回的相同视图 *@

_patientList.cshtml:

@model IEnumerable<table id="patientList" ><tr><th>@Html.DisplayNameFor(model =>model.Name)</th><th>@Html.DisplayNameFor(model =>model.Number)</th></tr>@foreach(模型中的var患者){<tr><td>@Html.DisplayFor(modelItem =>patient.Name)</td><td>@Html.DisplayFor(modelItem =>patient.Number)</td></tr>}

Patient.cs

公共类患者{公共字符串名称 { 获取；放;}public int Number{ 得到；放;}}

PatientController.cs

public PartialViewResult GetPatients(stringpatient_Name=""){var患者 = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))返回 PartialView("_patientList", 患者);}

而且正如 TSmith 在评论中所说，不要忘记通过 NuGet.

I am new in Asp.net MVC and i researched about Ajax.BeginForm but when i apply codes it did not work. Can you share very simple example with Ajax.Beginform with View, Controller, Model? Thanks.

解决方案

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.
