Question

在我的网页上，我有一个表，该表显示5行数据，当单击这些行之一时，将获取请求发送到控制器类中的方法，该方法返回一些数据并使用此数据填充表单。

我的主要问题是，根据我重定向到该页面的方式（从登录页面或其他页面），此获取请求并不总是有效。

如果我从登录名重定向到此页面，则工作正常，但是从其他地方，不会调用get请求。我曾尝试在控制器方法中添加断点，但该程序从未命中它（除非从登录重定向）。

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

控制器方法

//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();
}

添加/每个网址。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'})
...

jQuery.Get调用控制器方法并不总是有效
