javascript - Can't start new jquery functions during drag event -


i noticed css hover function doesn't trigger when dragging element outside page. wanted have "drop here" div lights when mouse on it, hover didn't work , neither this:

    // cosmetic thing     $('#dropzone').on({         dragover: function(e) {             $('#dropzone').addclass('on');         },         dragleave: function(e) {             $('#dropzone').removeclass('on');         }     });

i can see in inspector class being added, doesn't light up.

i tried closing popup drop area, mousemove event while dragging, event doesn't seem work until after let go of mouse:

        $(document).on('mousemove',function(e){             console.log('x:'+e.pagex+' y:'+e.pagey);             if (e.pagex <= 0 || e.pagex > $(document).width() || e.pagey <= 0 || e.pagey > $(document).height())             {                 dropperoff();                 $(document).unbind('mousemove');             }         });

lastly tried have constant mousemove tracking event populates mousex , mousey variable @ times. when move mouse, works fine, moment dragenter event fires, mousemove event stops working too.

this behavior making hard make page work. there way around or have give on making dropzone light , detect when drag event leaves page?

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
