knock.js的subscribe使用 通过$.ajax(); $get();解析JSON数据

//CS代码

<pre class="csharp" name="code">public ActionResult GetPhysicalSKUCost(int RequestTypeID, int SystemTypeID, int PhySKUID)
{
string serviceAddress = ConfigurationManager.AppSettings["MyCapacityService"].ToString();
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress + "/json/GetPhysicalSKUCost?RequestTypeID=" + RequestTypeID + "&SystemTypeID=" + SystemTypeID + "&PhySKUID=" + PhySKUID);

//返回的JSON数据
