javascript - Taking 3 array elements and making them a single formatted string -


i'm running ajax request returns json data:

{ "error":0, "fleet":[   {      "fleet_uid":859805,      "purpose":0,      "ower":1,      "time":520,      "con_time":647,      "from":[         6,         300,         2      ],      "target":[         6,         300,         6      ],      "start_user_id":20457507089,      "target_user_id":20510481089,      "start_planet_name":"tweenis12",      "target_planet_name":"p23808"   },   {      "fleet_uid":859803,      "purpose":0,      "ower":1,      "time":508,      "con_time":647,      "from":[         6,         300,         2      ],      "target":[         6,         300,         6      ],      "start_user_id":20457507089,      "target_user_id":20510481089,      "start_planet_name":"tweenis12",      "target_planet_name":"p23808"   } ], "count":2 }

i need target information inside fleet property. depending on time, there might no fleet entries , there might 10+.

inside target property 3 entries. need merge 3 entries single string formatted xx_xxx_xx

being unfamiliar js , jquery, i'm not sure how this.

try this,

var json = {"error":0,"fleet":[{"fleet_uid":859805,"purpose":0,"ower":1,"time":520,"con_time":647,"from":[6,300 ,2],"target":[6,300,6],"start_user_id":20457507089,"target_user_id":20510481089,"start_planet_name":"tweenis12" ,"target_planet_name":"p23808"},{"fleet_uid":859803,"purpose":0,"ower":1,"time":508,"con_time":647,"from" :[6,300,2],"target":[6,300,6],"start_user_id":20457507089,"target_user_id":20510481089,"start_planet_name" :"tweenis12","target_planet_name":"p23808"}],"count":2};  var arr = []; $.each(json.fleet, function(){     var value = this.target;     arr.push(value[0] + '_' + value[1] + '_' + value[2]);        }); alert(arr);

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
