-

this question has answer here:

i'm trying names pokemon api , putting div field in html, .text() function jquery doesn't seem place text html when put inside .getjson function. curious problem be? thanks.

<div class="container">     <div class="row">         <div class="col-sm-3" id="1">             <div id="name1"></div>         </div>         <div class="col-sm-3" id="2">             <div id="name2"></div>         </div>         <div class="col-sm-3" id="3">             <div id="name3"></div>         </div>         <div class="col-sm-3" id="4">             <div id="name4"></div>         </div>      </div>   </div>

javascript code

$(document).ready(function() { /*works*/ for(var j = 1; j < 5; j++){     $("#name" + j).text("hello"); } /*doesn't work*/ for(var j = 1; j < 5; j++){     var webaddress2 = "http://pokeapi.co/api/v1/pokemon/" + j;     $.getjson(webaddress2, function(data) {         console.log("test");         $("#name" + j).text("some text");     }); } });

create closure inside loop. since getjson asynchronous ,operation, loop finish it's execution without waiting getjson finish it's each execution.

you need bind value of j closure

$(document).ready(function() {   (var j = 1; j < 5; j++) {     (function(index) {       var webaddress2 = "http://pokeapi.co/api/v1/pokemon/" + index;       $.getjson(webaddress2, function(data) {         console.log("test");         $("#name" + index).text("some text");       });     }(j))   } });
