javascript - Jquery.Get 调用 Controller 方法并不总是有效

Question

在我的网页上，我有一个显示 5 行数据的表格，当单击其中一行时，将向 Controller 类中的一个方法发送一个 get 请求，该方法返回一些数据并使用这些数据填充表单。

我的主要问题是，根据我重定向到此页面的方式(从我的登录页面或从其他页面)，此获取请求并不总是有效。

如果我从登录重定向到此页面，则效果很好，但从其他地方，不会调用 get 请求。我尝试在 Controller 方法中添加断点，但程序从未命中它(除非从登录重定向)。

我尝试将 Jquery.click 方法添加到 $( document ).ready(function() { code here.. }) 中的函数中，但这没有什么区别。

Controller 方法

//This function returns a CSV of data
public string GetEntryFromRecentEntries(string userID, int index)
{
    string entryID = this.GetRecentEntries(userID, 5)[index][0];

    DOCOsoft.DataAccess.DatabaseReader dBReader = new DOCOsoft.DataAccess.DatabaseReader();
    List<SqlParameter> parameters = new List<SqlParameter>();

    parameters.Add(new SqlParameter("@entryID", entryID));

    StringBuilder entryData = new StringBuilder();
    using (IDataReader singleEntryReader = dBReader.ExecuteReader(ConfigurationManager.ConnectionStrings[1].ToString(), "get_entries", parameters))
    {
        while (singleEntryReader.Read())
        {
            entryData.Append(singleEntryReader["CompanyID"].ToString() + ",");
            entryData.Append(singleEntryReader["ProjectID"].ToString() + ",");
            entryData.Append(singleEntryReader["JobID"].ToString() + ",");
            entryData.Append(singleEntryReader["DurationInHours"].ToString() + ",");
            entryData.Append(singleEntryReader["Notes"].ToString());
        }
    }

    return entryData.ToString();
}

为每个网址添加/。如果您的项目在文件夹“@Url.Content("~/")”下运行，请使用。

...
$.get('/TimesheetEntry/GetEntryFromRecentEntries',{value: 'value'})
...

或

...
$.get('@(Url.Content("~/"))TimesheetEntry/GetEntryFromRecentEntries',{value: 'value'})
...
