jquery - AJAX Response and PHP Loop -


i using php retrieve records mysql database, send these ajax , loop through them, in order prepend rows existing table.

however can see last (most recent) record returned query. please point out going wrong?

ajax:

$.ajax({     type: "post",     url: 'feed.php',     data: {lastserial: true},     datatype: 'json',     success: function(data){         console.log(data); // logs `{direction: "o", cardno: "02730984", serialno: 20559303}`         $.each(data, function(key, value) {             // here want loop through returned results - example             $("#transactiontable").prepend('<tr><td>'+ serialno +'</td><td>'+ cardno +'</td><td>'+ direction +'</td></tr>');         });        }    });

feed.php

if(isset($_post['lastserial']) && $_post['lastserial'] == true) {   $query = "select timestamp, direction, cardno, serialno transactions";   // query returns approx. 20 results   $stmt = $conn->prepare($query);   $stmt->execute();   $result = $stmt->get_result();   while($row = $result->fetch_assoc()) {         $data["direction"] = $row['direction'];         $data["cardno"] =   $row['cardno'];         $data["serialno"] = $row['serialno'];   }   echo json_encode($data); }

also in php, should using while or if statement?

you're using single $data object , resetting contents each time. want build array of objects:

$data = array();  while($row = $result->fetch_assoc()) {   $data[] = array(      "direction" => $row['direction'],     "cardno"    => $row['cardno'],     "serialno"  => $row['serialno']   ); }  echo json_encode($data);

followed by:

// ... success: function(data){     $.each(data, function(key, value) {         // here want loop through returned results - example         $("#transactiontable").prepend('<tr><td>'+ value.serialno +'</td><td>'+ value.cardno +'</td><td>'+ value.direction +'</td></tr>');     });    }

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

jquery - Responsive Navbar with Sub Navbar -

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
