How Can I pass a javascript variable value to MVC controller? -


just example:

in javascript, have 2 variable values:

  1. movie id: 2
  2. rating value: 3

i need pass values mvc controller.

for start, easiest way use ajax call jquery.

here example:

first create action this. using index starting action should create view, , view passing data movies action

 public actionresult index()     {         return view();     }      public actionresult movies(int movieid, int ratingvalue)     {         string s =  movieid + " - " + ratingvalue;          return json(s, jsonrequestbehavior.allowget);     }

**now creating view index sending data on button click. , import jquery file , use in tag can see below **

 <html> <head> <meta name="viewport" content="width=device-width" /> <title>index</title> <script src="~/scripts/jquery-2.2.3.min.js"></script> <script type="text/javascript">     $(function () {         $('#senddata').click(function () {             var movie = 3;             var rating = 2;              var option = {                 url: '/home/movies',                 data: json.stringify({ movieid: movie, ratingvalue: rating }),                 method: 'post',                 datatype: 'json',                 contenttype: 'application/json;charset=utf-8'             };              $.ajax(option).success(function(data) {                 alert(data);             })         });     }); </script> </head> <body>     <div>          <input type="submit" value="send data" id="senddata" />     </div> </body> </html>

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
