:

//all zeros exaple: 
 

 
    function is_all_zeros(){          //default function return 
 
    var out=true; 
 
    if($(".offers_container").find(".offer_no span").length<1){ //if not found elements return false 
 
     \t out=false; 
 
    } 
 
    $(".offers_container").find(".offer_no span").each(function(){ 
 
     \t var this_text_int=parseInt($(this).text(), 10);   //integer value of found spin 
 
     if(this_text_int!=0){          //found value not 0 
 
     \t out=false; 
 
     } 
 
    }); 
 
    return out; 
 
    } 
 
    
 
    
 
    
 
    console.log(is_all_zeros());

//not all zerros example: 
 

 
    function is_all_zeros(){          //default function return 
 
    var out=true; 
 
    if($(".offers_container").find(".offer_no span").length<1){ //if not found elements return false
