c# - Alert Success or Error message for jQuery POST method -

I am using the following jQuery to save and save data:

  var Data = "sample data"; $ .post ('@ Url.Content ("~ / Student / SaveData"), {data: data} // I want a warning or error alert here   
 This is my controller :  
  public action SaveData (string data) {try to save the data // save logic // save the success signal // pass hold (exception pre) {// pass error signal} return See);}   
 If the error message is successfully saved otherwise, I want to alert the message of success.   
 
 
 first using the wrong assistant instead of  @ Url.Content  You are required to use the  @ Url.Action   
  var data = "sample data"; $ AZ ("Url.Action" ("SaveData", "Student"), Type: "Go", Data: {Sample: Data} Success: Function (Res) {Warning ("Success" );}, Error: function () {warning ("failure");}});   
 And your action will be:  
  Pub Lime Action Result SaveData (string sample = "") {return content (sample); }
