Ajax 没有击中控制器

Question

我这里有这段代码并且警报（'test'）被击中但由于某种原因.ajax 没有。 IT 不会给我任何错误，也不会向控制器传递任何信息。我以前做过 100 次，从来没有遇到过这个问题。有什么理由吗？谢谢所有的变量都有值等等。

尝试将 url 设为 url: '@Url.Action("Add_ICLog_LogEntryRecommendation_Submit", "References")',

<div class="card-block" id="RecommendationTypeAddModal">    
        @*@using (Ajax.BeginForm("Log/Investment/Committee/Recommendation/Add/Submit", "References", new AjaxOptions
            {
                InsertionMode = InsertionMode.Replace,
                UpdateTargetId = "ICLogRecommendationTypeAddForm",
                HttpMethod = "POST"
            },
                new { @id = "ICLogRecommendationTypeAddForm" }
            ))
            {*@

        @Html.HiddenFor(model => model.ICLogID);

        @Html.HiddenFor(model => model.SelectedIDs);

您的网址是您问题的原因：

url: "@Url.Action("Log/Investment/Committee/RecommendationType/Create/Submit", "References")"

改成：

 url:   @{Url.Action("Log/Investment/Committee/RecommendationType/Create/Submit", "References")}
