asp.net mvc - Live search MVC -

-

i'm looking live search asp.net , entity framework. i'm little bit green it. read needs use ajax, never used before , can't example. here piece of code, cshtml (part of textbox) 

    <div class="form-horizontal">         <hr />         <h4>search client: </h4>          <div class="input-group">             <span class="input-group-addon" id="name">                 <span class="glyphicon glyphicon-user" aria-hidden="true"></span>             </span>             @html.textbox("name", "", new { @class = "form-control", placeholder = "name" })         </div>         <div><h6></h6></div>         <div class="input-group">             <span class="input-group-addon" id="surname">                 <span class="glyphicon glyphicon-user" aria-hidden="true"></span>             </span>             @html.textbox("surname", "", new { @class = "form-control", placeholder = "surname" })         </div>         <div><h6></h6></div>         <button type="submit" class="btn btn-default" data-toggle="modal" data-target="#infomodal">search</button>     </div>

this part of controller: 

    public actionresult index(string name, string surname)     {         var searchlist = m in db.klienci                          select m;         if (!string.isnullorempty(name))         {             searchlist = searchlist.where(s => s.name.contains(name));         }         if (!string.isnullorempty(surname))         {             searchlist = searchlist.where(s => s.nazwisko.contains(surname));         }         return view(searchlist);     }

so search me clients name , surname, refresh full page when lost focus or after clicking button. how solve it, live search? after each keystroke search through database? i'm little bit green, me?

you can listen keyup event on input element, read value , send server using ajax. return results , in ajax call's success callback, update ui results.

$(function() {      $("#name,#surname").keyup(function(e) {             var n = $("#name").val();             var sn = $("#surname").val();             $.get("/home/index?name="+n+"&surname="+sn,function(r){                //update ui results                $("#resultstable").html(r);             });      });  });

the code listens key event on 2 input textboxes , read values , send /home/index action method using jquery method asynchronously.when action method returns response, update dom.

assuming resultstable id of table list results.

also, since returning partial view result ( without layout headers), should use return partialview() instead of return view()

if(request.isajaxrequest())     return partialview(searchlist);  return view(searchlist);

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
