c# - How to get selected drop down values from Controller MVC -

-

the following view :

 <div class="editor-label">         select currency :         </div>         <div class="editor-field">             @html.dropdownlist("currencyid", new selectlist(viewbag.currencyid, "value", "text"))  </div><div class="editor-label">          select gametype :         </div>         <div class="editor-field">            @html.dropdownlist("gametypeid", new selectlist(viewbag.gametypeid, "value", "text"), new { style = "width:100px" })             @html.validationmessagefor(model => model.gametypeid)         </div>          <div class="editor-label">           select category :         </div>         <div class="editor-field">           @html.dropdownlist("categorybygametype", enumerable.empty<selectlistitem>(), "select category")           @html.validationmessagefor(model => model.categoryid)         </div>

the following controller:-

 public actionresult create()         {             list<currency> objcurrency = new list<currency>();             objcurrency = db.currencies.tolist();             list<selectlistitem> listitems = new list<selectlistitem>();             listitems.add(new selectlistitem()             {                 value = "0",                 text = "select currency"             });             foreach (currency item_currency in objcurrency)             {                 listitems.add(new selectlistitem()                 {                     value = item_currency.currencyid.tostring(),                     text = item_currency.currencyname                 });             }             viewbag.currencyid = new selectlist(listitems, "value", "text");              list<gametype> objgametype = objgamebygametype.getdistinctgametypeid();             list<selectlistitem> listitems_1 = new list<selectlistitem>();             listitems_1.add(new selectlistitem()             {                 value = "0",                 text = "select game type"             });             foreach (gametype item_gametype in objgametype)             {                 listitems_1.add(new selectlistitem()                 {                     value = item_gametype.gametypeid.tostring(),                     text = item_gametype.gametypename                 });             }             viewbag.gametypeid = new selectlist(listitems_1, "value", "text");               return view();         }

the following jquery using casceding dropdown 

$(function () {             $("#gametypeid").change(function () {                 var theatres = "";                 var gametype = "";                 var mytestvar = "";                 var gametypeid = $(this).val();              mytestvar += "<option value= -1 >select category</option>";             $.getjson("@url.action("getcategorybygametype", "gamecombination")?gametypeid=" + gametypeid, function (data) {                 $.each(data, function (index, gametype) {                   //  alert("<option value='" + gametype.value + "'>" + gametype.text + "</option>");                     mytestvar += "<option value='" + gametype.value + "'>" + gametype.text + "</option>";                 });                 //alert(mytestvar);                 $("#categorybygametype").html(mytestvar);                 $("#gamebycategory").html("<option value=0>select game</option>");                 $("#limitvariantbygamebygametype").html("<option value=0>select limit variant</option>");                 $("#stakecategory").html("<option value=0>select stake category</option>");                 $("#stakebuyinbystakecategory").html("<option value=0>select stake buy in stake category</option>");       });      });     });

while submit data not able dropdown value if error come on creation

echo of andras said, can't use razor syntax in .js file if that's happening.

also should familiar debugging tools, browser using? have nice set of developer tools (some have them built in) can inspect page , request sent out when submit form.

you interactively use jquery in console of browser around also.

you don't show post create method, perhaps related code?

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
