javascript - Bind part of string to Angular scope variable -

-

i'm pulling json data server. inside json object i'm returning, have strings want able use placeholders dynamically insert values entered user in ui.

my understanding $compile for, can't seem work. i'm not sure if possible or if i'm approaching wrong way.

edit: not sure if i'm explaining well. got little further , updated plunk , code below

a simplified example (view plunk):

view:

<body ng-controller="mainctrl">     <input ng-model="name" type="text" />     <p ng-bind-html="myval">{{myval}}</p>     <p>{{name}}</p>   </body>

angular app:

var app = angular.module('plunker', ['ngsanitize']);  app.controller('mainctrl', function($scope, $compile, datasvc) {   init();    function init() {     $scope.data = datasvc.getdata();     $scope.name = '';   }    $scope.$watch('name', function(newval, oldval) {     var c = $compile('<span>' + $scope.data.vals[0].text + '</span>')($scope);     console.log(c);     console.log(c[0]);     $scope.myval = c[0];   }); });  app.service('datasvc', function () {   this.getdata = function () {     return {       vals: [         {           text: "hello {{name}}"         }       ]     }   }; });

this works $compile , console logs changes way want them happen, can't output on display.

i'd suggest use $interpolate service while assigning variable other, take care of evaluation of curly braces.

code

var app = angular.module('plunker', []);  app.controller('mainctrl', function($scope, $interpolate) {   $scope.test = "hello {{name}}!";   $scope.name = 'world';    init();   function init() {     $scope.concat = $interpolate($scope.test)($scope);   } });

working plunkr

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.
