javascript - Google Maps Routing with Waypoints from DB -


i have c# webforms application , i'm trying use google maps routing waypoints according example google maps api site. https://developers.google.com/maps/documentation/javascript/examples/directions-waypoints#try-it-yourself

this example represents want except want of points sql database rather dropdown lists shown. essentially, want loop through datareader , map/route points. data stored procedure. don't know how stored procedure results on java script.

thanks suggestions.

clarifying little, here have currently: in c# i'm calling stored procedure gets lat/long values db. 

 private void loadarray()     {         //get lat long db load google array.           sqlconnection conn = new sqlconnection();         sqlcommand cmd = new sqlcommand();         string connstr = configurationmanager.connectionstrings["furnituredb"].connectionstring;         conn.connectionstring = connstr;         conn.open();         cmd.commandtype = commandtype.storedprocedure;         cmd.connection = conn;         cmd.commandtext = "getgooglepins";         sqldatareader datareader = cmd.executereader();         var dtarray = new datatable();         dtarray.load(datareader);     }

on client side have:

function calculateanddisplayroute(directionsservice, directionsdisplay) {     var waypts = [];     var checkboxarray = document.getelementbyid('waypoints');     (var = 0; < checkboxarray.length; i++) {       if (checkboxarray.options[i].selected) {         waypts.push({           location: checkboxarray[i].value,           stopover: true         });       }     }

i want replace 'waypoints' values dtarray.

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 ...
