c# - Sending simple type from HTML form to ASP API -

i having troubles sending simple double number form asp api.

when submit form, firstly need remove submit button avoid sending redundant 'submit=submit' value api controller.

as have read in this article, set name of input field empty. if check http request in developer mode, body of sent data looks '=value'. method parameter decorated [frombody] attribute.

even this, controller method not value. allways zero.

what do?

my form looks so:

 <form action="@url.action("temperature","api")" method="post" >        <input type="number" name=" " step="0.25"/>        <input type="submit" name="submit" />    </form> </div>  <script>     $("form").submit(function () {         $(this).children('[name="submit"]').remove();     }); </script> 

the controller:

    // post: api/temperature     public void post([frombody]double value) //formdatacollection data     {                     temperature newentry = new temperature() { timestamp = datetime.now, value = value};         try         {             db.temperatures.add(newentry);             db.savechanges();         }         catch(exception e)         {             debug.writeline(e.message);         }      } 

try ajax...

change html little bit this:

 <div>        <input type="number" id="number" name=" " step="0.25"/>        <input type="button" id="submit" name="submit" /> </div> 

then:

$(document).on('click', '#submit', function () {     $.ajax({         type: 'post',         url: '/controllername/post',         data: {             value: json.stringify($('#number').val())         },         success: function (data) {             alert(data);         },         error: function (data) {             alert("an issue has occured");         }     }); }) 

also controller input parameters like:

public void post([frombody]string value) //convert string double later within method
