jquery - Ajax.IsAjaxRequest() always returns false? -


in controller class code "if(request.isajaxrequest())" returns false... can me figure out? if use ajax.beginform in cshtml page , not use jquery file returns true.

this cshtml file

<form method="get" action="@url.action("index")" data-otf-ajax="true" data-otf-target="#listofdata"> <input type="search" name="searchterm"/> <input type="submit" value="search"/>

this controller logic:

 public actionresult index( string searchterm)     {         var departments = db.departments.include(d => d.administrator);         if(request.isajaxrequest())         {              if (searchterm != null)             {                  var departments2 = db.departments.where(x => x.name.contains(searchterm));                  return partialview("_department", departments2.tolist());                           }         }         return view(departments.tolist());     }

and jquery file handle ajax request

$(function () { var ajaxformsubmit = function () {     var form = $(this);     var options = {         url: $form.attr("action"),         type: $form.attr("method"),         data: $form.serialize()      };     $.ajax(options).done(function (data) {         var $target = $($form.attr("data-otf-target"));         $target.replacewith(data);     });     return false; };  $("form[data-otf-ajax='true']").submit(ajaxformsubmit); });

use jquery.unobtrusive-ajax.min.js solve problem

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
