javascript - Extract a dinamic variable from an Ajax created element out of a foreach loop and perform another jQuery/Ajax call -


in profile.php there main elements can comment clicking post button. comments display in foreach loop. each comment has id created dynamically $comment->id. when new comment made, displayed in page without need refresh through ajax function. each comment has delete button has id of comment itself. comment can deleted without need of refreshing page using jquery , ajax. problem when new comment has been created ajax , want delete new comment without refreshing page (because there no edit feature). event bind newly created element jquery i’m using .on method not working. problem newly created element ajax event bind, jquery function has outside foreach loop. when outside foreach loop can’t access variable $comment->id (dynamically created) serves 2 purposes, create dinamic #id delete <p> tag can targeted jquery, , pass data through ajax delete_comment.php comment can erased database. in posts here in forum learned can variables outside loop creating array, feeding it, , extracting them. works, not ajax, page has refreshed array updated. how can extract foreach loop $comment->id, new created comment ajax can event bind element jquery , , after new comment has been created ajax, being able delete using ajax well.

many thanks.

my code:

profile.php

<div> main element  <script>     //process comment ajax     $('body').on('click','#post<?php echo $main_element->id;?>',function(){           //create new comment ajax through comment_creation.php }); </script>  <?php foreach($comments $comment) { ?> <!-- <div> new ajax comment created here </div> <p id="deletion<?php echo $comment->id; ?>">delete</p> --> <div> comment x </div> <p id="deletion<?php echo $comment->id; ?>">delete x</p> <div> comment y </div> <p id="deletion<?php echo $comment->id; ?>">delete y</p> <div> comment z </div> <p id="deletion<?php echo $comment->id; ?>">delete z</p>  <script>             $("body").on('click','#deletion<?php echo $comment->id; ?>',function(){             //delete comment using ajax passing $comment->id. delete_comment.php             //works elements  loaded in dom, not new ajax comments.  });  </script> <?php } ?> <script>     /* come way here access $comment->id outside foreach of new comment      created through ajax can targeted jquery , deleted using ajax well.     using array, feeding it, , extracting $comment->id of new ajax comment      works if page refreshed.     */ </script> </div>

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
