javascript - 循环遍历每个容器中的所有元素

Question

我需要循环遍历每个容器中的所有项目，每次循环到达新容器时都从 1 开始。

编辑:添加了 JSFiddle http://jsfiddle.net/ntv4k4LL/

例如

Container

 - 1 
 - 2
 - 3

Container

 - 1 
 - 2
 - 3

但目前正在发生

Container

 - 1 
 - 2
 - 3

Container

 - 4 
 - 5
 - 6

这是我的代码:

$('.index-slide-rel').each(function(){

     $(this).children('article').each(function(i,e){

         col++;

         if(i > 0 && i%cols === cols-1) {
             sx= 0;
             row++;
             col=1;
             sy += previewElementHeight;
         }                  
     })                     
});

$('.index-slide-rel').each(function(i, container) {
    // here, i should take the value 0 to 1, considering you have 2 containers.
    $(container).children('article').each(function(j, element) {
        // here, j should take the value 0 to 2, considering you have 3 elements.
    });                 
});
