<script>     var watchid = null;     $(document).ready(function() {         var optn = {             enablehighaccuracy: true,             timeout: infinity,             maximumage: 0         };         if (navigator.geolocation)             navigator.geolocation.watchposition(success, fail, optn);         else             $("p").html("html5 not supported");         $("button").click(function() {              if (watchid)                 navigator.geolocation.clearwatch(watchid);              watchid = null;             return false;         });      });      function success(position) {         var googlelatlng = new google.maps.latlng(position.coords.latitude,             position.coords.longitude);         var mapotn = {             zoom: 10,             center: googlelatlng,             maptypeid: google.maps.maptypeid.road         };          var pmap = document.getelementbyid("map");          var map = new google.maps.map(pmap, mapotn);         addmarker(map, googlelatlng);     }      function addmarker(map, googlelatlng, title, content) {         var markeroptn = {             position: googlelatlng,             map: map,             title: title,             animation: google.maps.animation.drop         };          var marker = new google.maps.marker(markeroptn);          var infowindow = new google.maps.infowindow({             content: content,             position: googlelatlng         });         google.maps.event.addlistener(marker, "click", function() {             infowindow.open(map);         });     } </script>

i found code.but code shows map of location.but want track bus location.how can location of bus.and tracker device preferable use?

thanks in advance

luckily, have managed implement similar app. check here: tracking app

.(use 32003693 credential , 6 freight id) . used script location: //i have omitted parts of code

< script type = "text/javascript" >    $(document).ready(function() {      if (navigator.geolocation) {        navigator.geolocation.getcurrentposition(showlocation);        //alert("geotrack working...");      } else {        $('#removemessages').html('this app not supported browser or os.');      }    });      //setinterval(showlocation(position),10000);    function showlocation(position) {    var latitude = position.coords.latitude;    var longitude = position.coords.longitude;    var freightid = <?php echo $freightid?>; //this used identify freight    $.ajax({      type: 'post',      url: 'controllers/getlocation.php', //php save tracked locations      data: 'latitude=' + latitude + '&freightid=' + freightid + '&longitude=' + longitude, //data coordinates      datatype: 'json',      success: function(msg) {        if (msg) {          $("#location").html(msg.locationname);          $("#lat").html(msg.lat);          $("#lgt").html(msg.lgt);          initializemap(msg.lat, msg.lgt, msg.locationname, msg.locationname);        } else {          $("#location").html('not available');          initializemap(0, 0, "undefined location", "undefined country"); //where initialize map        }          settimeout(function() {          showlocation(position); //this send request again , again after 3 seconds or time want. case set seconds patients sake        }, 1800);        }    });  } <  /script>    <!-- script initialize map , place maker on location obtained-->  <  script  src = "https://maps.google.com/maps/api/js?key=youur api key"  type = "text/javascript" > < /script> <    script type = "text/javascript" >    //initializemap();    function initializemap(custom_lat, custom_lng, title, address) {      var locations = [          [address, custom_lat, custom_lng, 2]      ];        var map = new google.maps.map(document.getelementbyid('map_canvas'), {        zoom: 8,        center: new google.maps.latlng(-0.2842285, 36.0729164),        maptypeid: google.maps.maptypeid.roadmap      });        var infowindow = new google.maps.infowindow();        var marker, i;        (i = 0; < locations.length; i++) {        var indetify = locations[i][3];        var iconset = "http://ruralshores.com/assets/library_maps.png"        // alert("identify:"+indetify);        if (indetify == 1) {          iconset = "../dist/images/map/1.png";        } else {          iconset = "../dist/images/map/2.png";        }        marker = new google.maps.marker({          position: new google.maps.latlng(locations[i][1], locations[i][2]),          map: map,          animation: google.maps.animation.drop,            icon: iconset,          optimized: false        });          google.maps.event.addlistener(marker, 'click', (function(marker, i) {          return function() {            infowindow.setcontent(locations[i][0]);            infowindow.open(map, marker);            marker.setanimation(google.maps.animation.bounce);          }        })(marker, i));      }      } <    /script>

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
