do getelementsbyclassname (and similar functions getelementsbytagname , queryselectorall ) work same getelementbyid or return array of elements? the reason ask because trying change style of elements using getelementsbyclassname . see below. //doesn't work document.getelementsbyclassname('myelement').style.size = '100px'; //works document.getelementbyid('myidelement').style.size = '100px'; your getelementbyid() code works since ids have unique , function returns 1 element (or null if none found). however, getelementsbyclassname() , queryselectorall() , , other getelementsby* methods return array-like collection of elements. iterate on real array: var elems = document.getelementsbyclassname('myelement'); for(var = 0; < elems.length; i++) { elems[i].style.size = '100px'; } if prefer shorter, consider using jquery : $('.myelement').css('size', '100px');

my python3 utility has function doesn't work (unless it's placed within selected directories, can run non-python pdflatex scripts successfully). want run utility set location on of template.tex files have, stored in various other locations. the python utility prompts user select pdflatex template file absolute path using tkinter.filedialog gui, runs user's selected pdflatex script using, example: os.system("pdflatex /afullpath/a/b/c/mytemplate.tex") python's os.system runs pdflatex , runs mytemplate.tex script. mytemplate.tex has numerous inputs written relative paths ./d/another.tex . so, python utility works fine long it's in exact same path /afullpath/a/b/c/mytemplate.tex user selects. otherwise pdflatex can't finds own input files. pdflatex delivers error message like: ! latex error: file ./d/another.tex not found because execution path relative python script , not pdflatex script. [ pdflatex needs use relative paths be...

i new discord's api, , working project needs able add guild member programmatically. i've learned how authorization code (with identify , guilds.join scopes), redeem access token, , user's id. last step use access code , user id add guild. command detailed here: https://discordapp.com/developers/docs/resources/guild#add-guild-member it seems need send put request url: https://discordapp.com/api/guilds/[guildid]/members/[userid] but results in response: {"code": 0, "message": "401: unauthorized"} i have tried including access token in authorization header: authorization: bearer [redacted] i've tried adding json body request: {"access_token":"[redacted]"} neither has worked. unsurprisingly, using both @ same time hasn't worked either. i wondered if permissions issue, discord confirms have guilds.join scope. json receive when exchanging authorization code access token: {...
