javascript - MVC send Model with ajax -


i having issue when trying send data save method using ajax. way because reusing form in several screens rendering partial page using same save function.

the problem having when way work , sends save function, serialized json made when page loads , doesn't updated values. updated values sent ajax, ideally without having capture values of every field on page.

below code using work sending save method original values listed in model

$("#save").click(function () {     var form = $('#form');      if (form.valid()) {         var data = '@html.raw(newtonsoft.json.jsonconvert.serializeobject(@model))';          $.ajax({             url: "/save",             type: 'post',             data: json.stringify({ modeljson: data }),             contenttype: 'application/json',             success: function (result) {                 savefade();             }         });     }      return false; });

firstly, please use .done, .fail, , .always methods on deferred jquery's $.ajax methods returns instead of success. secondly, not use razor methods directly in javascript, single quote character ' may cause syntax errors. instead close data in hidden div id, example: <div id="formdata">@html.raw(newtonsoft.json.jsonconvert.serializeobject(@model))</div>, in javascript do: var data = $('#formdata').html();. way can move scripts seperate .js file.

answering problem, must send actual form using ajax controller method. close fields in form, assign id form @using(html.beginform("method", "controller", formmethod.post, new { id = "myform" })), , send using ajax:

    $("#save").click(function () {         var form = $('#form');          if (form.valid()) {             var data = form.serialize();              $.ajax({                 url: "/save", //you can action attribute form using form.attr('action')                 type: 'post',                 data: data             }).done(function (result) {                 savefade();             });          }           return false;      });

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
