achieving angular ng-repeat like feature in javasc

Question

Im currently working on a code to achieve something like ng-repeat in angular. Basically a for-loop in html. the code takes every element with the class "loop" and processes it with the information given through the "info" attribute. Here is the code : HTML

<div class="loop" data-info="i in 1 to 10">
 -i-
</div>

Javascript

$(".loop").each(function(i){
 var loop_info=$(this).attr("data-info");
 var fin=loop_info.match(/(.*) in (\d+) to (\d+)/);
 var variable=fin[1],
 initial=fin[2],
 final=fin[3];
 var htm=$(this).html(),printed="";
 for(j=initial;j<=final;j++){
  var temp=htm;
  var r=new RegExp("-("+variable+")-","g")
  temp=temp.replace(r,j);
  printed+=temp;
 }
 $(this).html(printed);
}); 

Now i have also included the feature to replace the - variable - with the numbers.

Everything worked perfectly but when the loops are nested i.e

<div class="loop" data-info="i in 1 to 10">
 <div class="loop" data-info="j in 1 to 10">
  -j-
 </div>
</div>

it doesnt work on the nested loop ,i.e -j- doesnt get replaced with the numbers. I dont know why this is happening ,any help is appreciated.

The replacement fails because the HTML is changed, and the next .loop reference that jQuery had collected for your for loop, no longer represents what it was before.

Instead, make your for loop go in reversed direction:

$($(".loop").get().reverse()).each(function(i){
    // etc...

Snippet:

$($(".loop").get().reverse()).each(function(i){
  var loop_info=$(this).attr("info");
  var fin=loop_info.match(/(.*) in (\d+) to (\d+)/);
  var variable=fin[1],
      initial=fin[2],
      final=fin[3];
  var htm=$(this).html(),printed="";
  for(j=initial;j<=final;j++){
    var temp=htm;
    var r=new RegExp("-("+variable+")-","g")
    temp=temp.replace(r,j);
    printed+=temp;
  }
  $(this).html(printed);
});

<div class="loop" info="i in 1 to 10">
    <div class="loop" info="j in 1 to 10">
      -i-:-j-
    </div>
</div>
