Javascript/JQuery:通过匿名函数在调用each()时从PARENT函数立即返回

Question

例如:

> function foo() {
>    jQuery(whatever).each( function() {
         return; // this just exits the anonymous function - is there a way to return from foo?
     }
   );
> 
> }

**更正:添加更多细节.使用标志允许从PARENT函数返回**

function foo() {
   var doreturn = false;
   jQuery(whatever).each( function() {
     if(youwanttoreturn){
         doreturn=1;
         return false;
     }
   });
   if(doreturn)return;
}
