javascript - jQuery function to loop through elements and set class names based on order compared to an element with a specific class name -


current codepen: http://codepen.io/anon/pen/rvnpvg

<div class="box">box1</div> <div class="box">box2</div> <div class="box active">box3</div> <div class="box">box4</div> <div class="box">box5</div>

i'm working on best way , love input.

i'm writing function loop through set of elements have class name of box. 1 of elements in list have class name of active. elements prior 1 active class, want set class name of done. of elements after 1 active class, want set class name of hidden.

the way i've done seems unnecessarily iterative , i'm wondering if can provide elegant method.

any appreciated.

thank in advance time!

var $activebox = $('.box.active'); $activebox.prevall('.box').addclass('done'); $activebox.nextall('.box').addclass('hidden');

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
