javascript - Moving element to cursor position gets logged, but the change of position is not applied -


i have object chainable functions, works ok-ish. clicking on triangle trigger animation , translates element accordingly. have function should translate triangle current mouse position, js following:

movetotarget: function(e) { var mousex = 0,  mousey = 0, xp = 0, yp = 0; xp += (mousex - xp) / 12; yp += (mousey - yp) / 12; block.style.left = xp + 'px'; block.style.top = yp + 'px'; settimeout(movetotarget,30);  return this;

keep in mind 1 of methods on object animateblock , not sure if have call animateblock.movetotarget in settimeout.

this invocation:

container.addeventlistener("click", function(e){ console.log(e.pagey); // log y position animateblock.movetotarget;});

i no js lint errors, no runtime errors thrown in console, not apply translation reason, missing here?

here's working codepen: https://codepen.io/anon/pen/mmxwwv?editors=0111

i had make several changes, apologies:

  • you calling movetotarget() without parameter, event
  • the movetotarget() function wasn't doing anything. weren't using event, values 0.
  • i removed margin: 50% 0; triangle, since messed x position (making using translatex() difficult).
  • i put "px" directly inside function, parameters numbers now.
  • new function movexandy() modify both translatex() , translatey() @ same time (otherwise they'd overwrite each other).
  • code's kind of mess, i'm not used editing on codepen, apologies that.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
