In javascript-smarty, how does foreach traverse the number of loops?

The for loop shows the number of loops, but the foreach does not know how to get the {code...} for loop shows the number of loops, but the foreach does not know how to get it.

 
 
Serial number
  
Name
  
Quantity
  
Amount
  
 
The number of cycles is displayed as shown in the question, each time + 1
      
{$ Goods. goods_name}
      
{$ Goods. goods_number}
      
{$ Goods. subtotal}
      
    
  
The result is almost the same: the number of serial numbers is 1 aa 12 52.002 bb 10 26.003 cc 5 99.004 dd 16 88.00

{Foreach name = xxx}
$ Smarty. foreach. xxx. index

Is it easy for Baidu to solve this problem?

  
 
{$goods@iteration}
    
{$goods.goods_name}
    
{$goods.goods_number}
    
{$goods.subtotal}

  

This is the number of cycles

{$goods@index}

This is the index of the array.
