javascript - Pass in For Loop Parameter into Each Statement -


i have json feed pulling each statement. loop var i value used in each statement. in example below loop run 0, 1, 2. if i == 1 run json feed i = 1 value. when if statement gets triggered json each statement runs through items b/c it's i value starts @ 0. console.log have in place returns 0, 1, 2. return 1. thank help.

edit
focus make $.each(data.data, function(i, item) { i within each statement use number i equal in loop statement. if there 3 items in json file, item 1 ran.

for (var = 0; < 2; i++) {     if (i == 1) {         $.getjson("/json/v2_ilt_map.cfm?feedtype=iltmap_scheduled&customerid=1&trainingobjectparent=3", {}, function(data, i) {             $.each(data.data, function(i, item) {                 console.log(i);             }         }):     } }​

you'll need introduce additional function scope make work.

function checkonly(i) {   return function(data) {     $.each(data.data, function(ii, item) {       if (ii == i) console.log(ii);     });   }; }  (var = 0; < 2; i++) {     if (i == 1) {         $.getjson("/json/v2_ilt_map.cfm?feedtype=iltmap_scheduled&customerid=1&trainingobjectparent=3", {}, checkonly(i));     } }

here, callback passed $.getjson created inside function. doing that, variable "i" that's examined in .each() loop copy of "i" for loop. handler function therefore has fixed value compare against.
