javascript - How do I modify the page I'm serving in node.js -

-

ok, have server.js 

var express     = require("express"),     app         = express(),     bodyparser  = require('body-parser');  app.use(bodyparser.urlencoded({ extended: true })); app.use(bodyparser.json());  app.use(express.static(__dirname + '/'));  app.post('/message', function(req, res) {   var jsondata = req.body;   if (jsondata.hasownproperty('phone1')) {       console.log("phone 1 connected to", jsondata.phone1.connection,                   "and has downlink speed of", jsondata.phone1.dl, "mbps");   } else    if (jsondata.hasownproperty('phone2')) {       console.log("phone 2 connected to", jsondata.phone2.connection,                   "and has downlink speed of", jsondata.phone2.dl, "mbps");   } });  var port = 1337; app.listen(port); console.log("running @ port " + port);

and see want stuff when server gets posted on /message. can console.log stuff yes, want change things on web page server serving. post requests coming server. server presents them.

how can without having update page?

i'm using angularjs on client side, way client side pick json data nice.

i hope present data in highcharts gauges , charts simple text update on page element (e.g. <p id="example">) fine answer question.

i know can jquery node still lack window element manipulate presented data. nw.js might want, haven't still tried though, suspect there might solution problem.

if want push new content client (opposite flow client requesting data server), websockets option (see http://socket.io/ common library).

alternatively, setup long polling on client side. using javascript periodically 'poll' server information using setinterval or similar approach.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
