javascript - Sort unordered list based on data-row and data-col -


i have page 'ul' (unordered list) insert 'li' elements on fly. 2 attributes: data-col , data-row. 2 attributes arbitrary , can value. (any real positive number)

is there way re-order 'li' elements based on data-row , data-col? not have visible, need 'ul' element children ordered.

extra info: reason because have back-end code needs read 'ul' element children in sequence , populate table element. it´s i´m saving multi-dimensional array 1 dimension array.

thanks :)

you can use jquery.sort() sort list of li elements based on row, column, , re-append sorted list ul. appended list replaces previous unsorted version:

var ul = $('#mylist');    var lis = $('#mylist > li');    lis.sort(      function(a, b) {      var ela = $(a);      var elb = $(b);            var res = +ela.data('row') - elb.data('row');            if (res == 0)   // if rows same, sort column        res = +ela.data('col') - elb.data('col');            return res;    }    ).appendto(ul);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>    <ul id="mylist">    <li data-col="2" data-row="14">14, 2</li>    <li data-col="2" data-row="1">1, 2</li>    <li data-col="3" data-row="4">4, 3</li>    <li data-col="1" data-row="3">3, 1</li>    <li data-col="1" data-row="4.5">4.5, 1</li>  </ul>

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 ...
