this question has answer here: how compare arrays in javascript? 37 answers i started with: "1:2".split(':') == ["1","2"]; // false then tried: [1,2] == [1,2]; // false and ultimately: [] == []; // false i've since found that: "1:2".split(':').tostring() == [1,2].tostring(); // true so i've solved initial issue (kind of) why can't arrays match each other? javascript arrays objects , can't use equality operator == understand if content of objects same. equality operator test if 2 object same instance (e.g. myobjvariable==myobjvariable , works null , undefined too). if need check if 2 array equals i'd recommend traverse both arrays , verify elements have same value (and 2 array have same length). regarding custom objects equality i'd build instead specific...

i'm developing application might use dropbox it's storage. my question is, can link folders between computers, more 1 person upload/download to/from same folder. do have worry threading? happens if while person downloading file, other person updating same file. dropbox lock file while 1 operation being done on it? if not, guess have handle in application correct? yes, have worry this. dropbox uses optimistic concurrency. every file has rev (revision) can reference when uploading file (e.g. via /files_put ). basic idea when download file, keep track of rev , , when upload file, pass rev parent_rev parameter. if file has been changed in meantime different user (via shared folder) or same user (via different device), rev won't match. happens dictated autorename parameter. if specify true , file renamed on conflict. if specify false , upload fail altogether, , app can decide do. essentially, can't stop users updating files simultaneously on multipl...

i have handle process, might, or might not, handle of running process. following known handle object: the handle has process_terminate access right. the handle not pseudo-handle, i.e. not return value of getcurrentprocess . is there way know whether handle of current process? i thought using getprocessid , unfortunately fails access denied error, because handle doesn't have process_query_limited_information access right. if have sufficient access target process, can create new handle process_query_limited_information access right using duplicatehandle() . can use handle process id. unless process modifies own security permissions, should have (at least) process_query_limited_information access itself, if duplicating handle fails access denied error unlikely handle points process. if want make absolutely certain, can try opening handle process process id - if fails messing acl , bets off. :-)

i want create multilevel select2 options indentation don't want use optgroup elements because want allow select main categories. there way style if select2? my raw html select looks this: <select class="js-select-multiple"> <option class="l1">option 1</option> <option class="l2">suboption 1</option> <option class="l2">suboption 2</option> <option class="l2">suboption 3</option> <option class="l1">option 2</option> ... </select> <script>$(".js-select-multiple").select2({maximumselectionlength: 5});</script> so without using select2 can add text-indent property .l2 class. seems select2 doesn't use classes used option, styling classes won't work. is there workaround that? you're correct in recognizing select2 not carry css classes <option> tags results list. has not explicitly t...
