javascript - fadeIn() elements in array, randomly (ie, not in order), at different times -


i have several sentences written, "words" within tags, same class. have managed fill array elements. however, appear @ same time, , in order down paragraph in sequential order (ie, if element 5 first printed, n+1 element greater 5, , on)

also, in loop, if for(var i=0;i < numelements;i++) .....32 number of unique elements. must set numelements way larger 32. ie elements not appear unless numelements >=90. why this?

attempt:

$(document).ready(function() {     var spanarray = [];     var spanlength, index;     /* populate array elements of class .fadein */     $(".fadein").each(function() {         spanarray.push(this);        })      spanlength = (spanarray.length);      for(var = 0; < 33; i++) {          index = math.floor(math.random() * (spanarray.length));               $(spanarray[index]).delay(400).fadeto(500,1, function() {                 $(spanarray).splice(index,1);    });     } });

jsfiddle

basically: all elements appear @ same time numelements not display elements unless numelements >>> actualnumelements

ex: working jsfiddle

i found answer wondering! 

$(document).ready(function() { $("#contact").click(function() {      $(".fadein").each(function() {         var word = this;          settimeout(function() {              $(word).css("opacity","1");         }, math.random() * 3000)  });  });

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 ...
