When you work with each loop in jquery, the out-of-loop JS will still execute

Today in the project bug, I found a problem, I get a div in all input, and value, judge a condition, but the outside of the loop JS can still be executed.

   $ (". Tab-reg-next input"). each (function() {            if ($ (). attr ("id") = = 1) {                return  ;            }        });

Very strange, generally return will terminate JS, but today is not expected to be, jquery in each loop, return is not good, because the return in each and the outside of the function is not related, but only a single loop, so change to the following way, You can do it.

var true ;        $ (". Tab-reg-next input"). each (function() {            if ($ (). attr ("id") = = 1 ) {                false;                 return false ;            }        });         if (! result) {            $.fd.msg.notice ("Picture is too big, over 5MB")            ; return         }
