javascript - how to count total number of ajax response data sets inside for loop? -


i calling ajax , output api response in textbox. want count total number of data sets received(counteri) , display each time click button. example if click button first time want alert display counteri=20 , next time click button display counteri=40 and... counteri=60.

currently code keeps showing 20 each time , not adding values. 1 tell me how fix this.thanks

 <script>             var maxnumid = null;             var counteri= null;             function callapi() {                 $.ajax({                     type: "get",                     datatype: "jsonp",                     cache: false,                     url: "https://api.somesite.com/......"),                     success: function(data) {                   maxnumid = data.pagination.next_num_id;                 (var = 0; < 100; i++) {  $(".galaxy").append("<div class='galaxy-placeholder'><a target='_blank' href='" + data.data[i].link +"'><img class='galaxy-image' src='" + ok.images.standard_resolution.url +"' /></a></div>");                        document.myform.outputtext.value = document.myform.outputtext.value+data.data[i].images.ok.url+'\n' ;                         //alert('www!'+i);                          counteri=i;                     }                      }                  });               counteri=counteri+counteri;                      alert('counteri now: ' + counteri);             }             </script>             <body>             <br>             <center>             <div id="mydiv"></div>         <div class="galaxy"></div>             <button id="mango" onclick="callapi()">load more</button>              </html>

edit: adding in start of success added total number of records ajax response

var num_records = object.keys(data.data).length; num_records2=num_records2+num_records; alert('number of records:'+ num_records2);

and 

var num_records2 =null; // outside function

ajax async calls.

move alert after for. not outside success callback.

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.
