javascript - .done() callback when using custom jQuery Animations -


i'm using following functions in order animate slides slideup() or slidedown():

(function($) {         jquery.fn.slidelefthide = function(speed, callback) {       this.animate({         width: "hide",         paddingleft: "hide",         paddingright: "hide",         marginleft: "hide",         marginright: "hide"       }, speed, callback);     }      jquery.fn.slideleftshow = function(speed, callback) {       this.animate({         width: "show",         paddingleft: "show",         paddingright: "show",         marginleft: "show",         marginright: "show"       }, speed, callback);     } })(jquery);

the thing is, want call function only once after animation ends. tried doing by:

$(".item").slidelefthide(function() {     $(this).remove();  }).done(function() {     $(".tab").each(function() {         $(this).attr('data-status', 'success');     }); });

when execute code, error message saying cannot read property 'done' of undefined. same happens .then() instead of .done().

how can solve this?

thanks!

(function ($) {     function slideleftbinder(action) {         return function () {             var = 0,                 speed = ((number(arguments[i]) === parsefloat(arguments[i]) && !isnan(arguments[i])) || undefined) && arguments[i++],                 callback = (typeof arguments[i] === 'function' || undefined) && arguments[i++],                 self = this;              return new promise(function (resolve) {                 var completed = 0;                  self.animate({                     width: action,                     paddingleft: action,                     paddingright: action,                     marginleft: action,                     marginright: action                 }, {                     duration: speed,                     complete: callback,                     always: function() {                         if (self.length === ++completed) {                             resolve(self);                         }                     }                 });             });         };     }      jquery.fn.slidelefthide = slideleftbinder('hide');     jquery.fn.slideleftshow = slideleftbinder('show'); })(jquery);

use this:

$(".item")     .slidelefthide(function() {         $(this).remove();     })     .then(function(selector) {         console.log('selector: ', selector);         $(".tab").attr('data-status', 'success');     });

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 ...
