Question

我有一个学生列表，我正在尝试实现一个自动完成的搜索栏。

这是我的控制器方法

[HttpPost]
public ActionResult SearchForStudents(StudentViewModel studentViewModel)
{
    return PartialView("_StudentListTable", 
_repository.GetStudentViewModel(studentViewModel.SearchStudent));
}

public JsonResult AutoComplete(string term)
{
    var model = _repository.FetchGeneralStudentSearchResult(term);
    return Json(model, JsonRequestBehavior.AllowGet);
}

搜索时调用SearchForStudents方法（此部分工作正常）。现在，不起作用的部分是AutoComplete方法。每次用户在搜索框中键入内容时，都会调用此方法。但它并没有被称为..永远..

这是我的剃刀观点

@using Bulletin.Models
@model Bulletin.Models.StudentViewModel

@using (Ajax.BeginForm("SearchForStudents", "Admin", null, new AjaxOptions {             
HttpMethod = "POST", InsertionMode = InsertionMode.Replace, UpdateTargetId =         
"StudentTableList" }))
{
    @Html.TextBoxFor(model => model.SearchStudent, "", new { @type = 
"string", @data_autocomplete_source = Url.Action("AutoComplete") })
    <input type="submit" name="searchbt" value="Search" />
}

<hr />
<div id="StudentTableList">
    @Html.Partial("_StudentListTable")
</div>


@section Scripts{
    <script src="~/Scripts/jquery-3.3.1.js"></script>
    <script src="~/Scripts/jquery-ui-1.12.1.js"></script>
    <script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
    <script src="~/Scripts/MonScript.js"></script>
}

这是“MonScript.js”文件，据说负责检测输入并调用方法

$(function () {
    $("input[data-autocomplete-source]").each(function () {
        var target = $(this);
        target.autocomplete({ source: target.attr("data_autocomplete_source") });
    });
});

所以我的问题我猜是为什么它不起作用，我可以做些什么来解决这个问题？提前感谢您的帮助：D

编辑：这是剃刀被解释为

<form action="/Admin/SearchForStudents" data-ajax="true" data-ajax- 
method="POST" data-ajax-mode="replace" data-ajax-update="#StudentTableList" 
id="form0" method="post">
    <input data-autocomplete-source="/Admin/AutoComplete" id="SearchStudent" 
     name="SearchStudent" type="string" value="" />    
    <input type="submit" name="searchbt" value="Search" />
</form>

编辑2：浏览器的控制台向我发送异常

ASP.NET MVC JQuery自动完成TextBox不起作用
