javascript - Looping through the ajax call -


i trying loop through ajax calls surprise loop not working.

for (var = 0; < lengthtotal; i++) {                  $.ajax({         datatype: "json",         url: "{{action('reportingcontroller@getdailystats')}}/" + getcampaign[i] + "/" + getstartdates[i] + "/" + getenddates[i]     }).done(function(resultthree) {         console.debug(i) //is 2         $(resultthree).each(function(index2, value2){              bartable = [ getcampaignname, value2.impressions, value2.clicks ];             xbyxtable($('tbody#stats'), bartable);             //valueinside++;                                                                                         }); // end resultthree     });  //end done  }

this not best practice create functions inside of loop.

try this:

for (var = 0; < lengthtotal; i++) {     (function (i) {         $.ajax({             datatype: "json",             url: "{{action('reportingcontroller@getdailystats')}}/" + getcampaign[i] + "/" + getstartdates[i] + "/" + getenddates[i]         }).done(function (resultthree) {             console.debug(i) //is 2             $(resultthree).each(function (index2, value2) {                  bartable = [getcampaignname, value2.impressions, value2.clicks];                  xbyxtable($('tbody#stats'), bartable);                 //valueinside++;                                                                                             }); // end resultthree          }); //end done      })(i); }

the reason work closures. variables outside functions accessible inner functions after function exited. here, i inside for loop changed until response of ajax comes. using closure, i copied local variable of function.
