javascript - Create table if data from ajax not empty -


first have html:

            <div class="showtable" style="display: none;">              <table id="example" class="table table-responsitive" cellspacing="0" width="100%" style="margin-top:30px;">         <thead>             <tr>                 <th>id</th>                 <th>broj računa</th>                 <th>kupac</th>                 <th>datum izdavanja</th>                 <th>rok za plaćanje</th>                 <th>status</th>                  <th></th>               </tr>         </thead>       </table>             </div>             <div class="showinfo" style="display: none"> </div>

after write js:

$(document).ready(function() {     drawvisualization();      }); function drawvisualization() {      console.log('proba');     $.ajax({             url: "getracuni.php",             type: "post",             async: true,              datatype: "html",              success: function(json) {             console.log(json);             if (!json.data){                 json.data = [];                 $('.showinfo').show();             } else {              var podaci = json.data;              $('.showtable').show();              showtable(podaci);             }             },             error: function(data) {             console.log(data);             }         });             };

so here try make this: 1. if data ajax not empty create datatable function showtable(podaci); 2. if data ajax empty want show div class 'showinfo'.

my showtable(podaci) function is:

function showtable(podaci) {      $('#example').datatable({            data: podaci.data,                     paging: false,                     "dom":' <"search"f><"top"l>rt<"bottom"ip><"clear">',             bfilter: false,                     "olanguage": {     "sinfo": 'ukupno _end_ računa.',     "sinfoempty": 'nema podataka o računima',     "semptytable": "nemate račune, dodajte klikom na dugme ispod.", },          // end ,                     "columns": [{                             "data": "id"                         }, {                             "data": "br"                         },                          {                             "data": "kupac"                         },                         {                             "data": "datum"                         },                         {                             "data": "rok"                         },                         {                             "data": "status"                         },                         {                             "data": "akcija"                         }                     ],                     "columndefs": [                             {                         "targets": 6,                         "data": "akcija",                         "render": function(data, type, full, meta) {                             // return data;                              return '<div style="float:right;"><div class="btn-group"><a href="#" class="btn btn-primary btn-sm dropdown-toggle" data-toggle="dropdown" aria-expanded="false">izmeni <span class="caret"></span></a><ul class="dropdown-menu"><li><a href="#">izmeni</a></li><li><a href="#">pošalji</a></li><li><a href="#">opomeni</a></li><li><a href="#">plaćeno</a></li><li><a href="#">stoniraj</a></li><li><a href="#">kopiraj</a></li><li><a href="#">obriši</a></li></ul></div> <i  data-toggle="modal" data-target="#delete" class="fa fa-times"></i></div>';                         }                     },                             {                         "targets": 0,                         "visible":false                             }     ]                 }); }

also data ajax in json format:

{"data":[{"id":1,"br":"1-2015","kupac":"adakolor","datum":"2015-05-19","rok":"2015-05-21","status":"placeno"},{"id":2,"br":"2-2015","kupac":"milenk","datum":"2015-05-27","rok":"2015-05-28","status":""}]}

i think write fine when try run code blank screen. wont show there...

change condition if (!json.data) if (json.data!=null)

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.
