未捕获的类型错误未定义不是函数

我是 JQuery 新手，不知道如何处理诸如未捕获之类的错误TypeError: undefined is not a function。我不知道如何按顺序排列下面的 jQuery 代码。有人可以安排一下吗....

@model Mvc4_WebGrid_CRUD.Models.PagedCustomerModel
@{
ViewBag.Title = "WebGrid CRUD Operations";
WebGrid grid = new WebGrid(rowsPerPage: Model.PageSize);
grid.Bind(Model.Customer,
          autoSortAndPage: false,
          rowCount: Model.TotalRows
); 
}   
    <style type="text/css">
    #grid {
    clear: both;
    width: 80%;
    margin: 0px;
    border: 1px solid #c7c5c7;
}
    #grid thead, #grid tfoot td {
        text-align: left;
        font-weight: bold;
        height: 35px;
        color: #000;
        background-color: #d2d0d2;
        border-bottom: 1px solid #e2e2e2;
    }

    #grid td {
        padding: 4px 6px 0px 4px;
        vertical-align: top;
        background-color: #f5f5f5;
        border-bottom: 1px solid #e2e2e2;
    }

input {
    border: 1px solid #e2e2e2;
    background: #fff;
    color: #333;
    font-size: 1.2em;
    margin: 2px 0 2px 0px;
    padding: 2px;
    width: 170px;
}
 </style>   
 <script src="~/Scripts/jquery-1.8.2.js"></script>

 <script type="text/javascript">
$(document).ready(function () {
//Here is where I get the error
    $("#results").dialog({
    autoOpen: false,
    title: 'Title',
    draggable: false,
    width: 500,
    height: 400,

当我尝试打开上面代码中的对话框时，我刚刚收到错误。我可以找到未捕获的错误。可能是因为 jQuery 没有按顺序休息，一切都很好。谁能把上面的内容整理一下。非常感谢

您有一个明显的问题可能会导致问题。你的 HTML 有一个 divclass="results"，但你的选择器说#results（即找到一个元素id="results")

You could将选择器更改为.results（正如@VeldMuijz 在评论中建议的那样），but你还有一个 AjaxActionLink它需要一个指定的 idUpdateTargetId="results"

相反，将 id 添加到结果 div 中。

例如改变这个：

<div class="results" style="display:none;"></div>

to this:

<div id="results" style="display:none;"></div>

我还建议在 MVC 项目中将 JS 代码放在单独的 JS 文件中。 Visual Studio 无法在同一视图中调试 Razor 和 Javascript，但如果脚本位于其自己的文件中，则可以。
