javascript - JQuery - Swapping two elements does not work after first move -


i have function bubble sort among content of various divs. each swap operation, swaps divs too, using jquery swapsies plugin. problem tht swap once, , after other swap operations:

function swap(id1, id2){  $('#' +id1).swap({   target: id2,   opacity: "0.5",   speed: 1000,   callback: function() {     } });  }  function bubblesort() {  var ret=[]; $(".num-div").each(function(){ ret.push($(this));});  let swapped; {   swapped = false;   (let = 1; < ret.length; ++i) {      if (ret[i - 1].html() > ret[i].html()) {       swap(ret[i-1].attr('id'), ret[i].attr('id'));       [ret[i], ret[i - 1]] = [ret[i - 1], ret[i]];        swapped = true;      }   } } while (swapped); return ret;

}

in first step i=1 works , swaps ret[i-1] ret[i], after not work.

the swap plug-in not process calls when busy animation. can see in source code of plug-in:

if (options.target!="" && !swapping) {

the swapping variable true during ongoing animation, , if skip new animation without notice.

anyway, want animations happen in sequence, not @ same time. purpose suggest using promises , rather new async/await syntax.

first promisify swap function, returns promise. add async , await keywords @ appropriate spot, , ... work.

one more caution: if data numerical, , want sort numeric value, need convert strings numbers before doing comparison, instance applying unary + this: +ret[i].text()

here working demo:

function swap(id1, id2){      return new promise(resolve =>           $('#' +id1).swap({            target: id2,            opacity: "0.5",            speed: 500,            callback: resolve          })      );  }    async function bubblesort() {      var ret=[];      $(".num-div").each(function(){           ret.push($(this));      });        let swapped;      {          swapped = false;          (let = 1; < ret.length; ++i) {              if (ret[i - 1].text() > ret[i].text()) {                  await swap(ret[i-1].attr('id'), ret[i].attr('id'));                  [ret[i], ret[i - 1]] = [ret[i - 1], ret[i]];                  swapped = true;              }          }      } while (swapped);      return ret;  }    bubblesort().then( ret => {      console.log($.map(ret, x => $(x).text()));  });

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 ...
