javascript - jQuery plugin: Prevent override options -


i did custom plugin add common functionality , validations jquery file upload plugin. resume can idea.

$.fn.mycustomupload = function(options) {      if (!$(this).is('input:file')) {         return false;     }      $(this).fileupload({         maxchunksize: options.maxchunksize,         maxfilesize: options.maxfilesize,         acceptfiletypes: options.allowedtypes,         type: 'post',         datatype: 'json',          add: function (e, data) {             // common validations         },          start: function (e) {             // foo             if (options.onuploadstart) {                 options.onuploadstart();             }         },          fail: function(e, data) {             // foo             if (options.onuploaderror) {                 options.onuploaderror(result);             }         },          done: function(e, data) {             // foo             if (options.onuploaddone) {                 options.onuploaddone(media_data);             }         }     }); };

the thing made validations or process data, , return results callbacks. but, notice callbacks override next call plugin.. so, upload file in 1 place, , re result show in another! i'm doing wrong?

should need store options each input element, .data()?

edit 2: fiddle of html, , js structure (not functional) https://jsfiddle.net/a6axfm3v/

edit: use plugin in 2 ways

$input.mycustomupload({     // ...     onuploadstart: this.onnewpostuploadstart.bind(this),     onuploadprogress: this.onnewpostuploadprogress.bind(this), //this reference object     onuploaderror: this.onnewpostuploaderror.bind(this),     // ... }); $uploads_buttons = $container.find('._attach_image');  $uploads_buttons.each(function() {     var $upload_button = $(this);     var $parent = $upload_button.parents('._post-container');      $upload_button.mycustomupload({ /*options, callbacks, etc*/}); });

$input has own callbacks, , $uploads_buttons have same, different $input ones..

thanks.

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

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
