javascript - jqplot error with multiple pie charts on external js file -


i using jquery pie chart/donut display data on several pages. there 1 chart each page, has different data.

my plan put coding each of pie charts external js file referenced on each page in page template.

however, when script jqplot donut chart on linked js file gets chart doesn't have matching id on page, none of scripts following charts work.

this means first chart listed in script works. other pages not displaying charts, there script above doesn't have matching id on page.

for example, chart 1 , chart 2 both have coding in js file, code chart 1 first, code chart 2 second. on page 1, pie chart 1 displays has id on page pie chart 1. however, on page 2, there no matching element pie chart 1, , script throws error , doesn't code pie chart 2, not displayed in matching element on page 2.

usually when similar, if code doesn't have matching id on page code ignored. there seems in jqplot causes error if code not matched element.

this seems basic implementation me. i'm sure many people use pie chart on multiple pages different data sets , put coding them in single js file, rather in-page or referencing multiple individual js files.

any on issue appreciated many thanks

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
