javascript - AngularJS : directive ng-repeat doesn't work in link function -


i'm trying create directive "auto complete" , display data underneath form element.

i'm having problem getting ng-repeat in inserted html display array of information gets attr.

in directive i'm monitoring attr waiting data populated, , once it's populated, set variable in directive , try ng-repeat data in ul html. nothing being shown, though variable populated in directive.

any ideas why? i've tried doing lot of things, i'm sure it's parent/child scope issue, not sure need change? i'm trying keep directive scope isolated can reuse directive multiple times.

    //directive     function autocomplete($parse, $compile, $timeout) {         var directive = {             restrict: 'ea',         //  scope: true,             require: '?ngmodel',             link: link         };          return directive;          function link(scope, elem, attr, ngmodel) {             var cdata = [];              var modelget    = $parse(attr['ngmodel']);             var modelset    = modelget.assign;               scope.$watch(function() {                 return elem.attr('data');             }, function(newval) {                 cdata = newval;                 console.log(cdata);             });              $timeout(function(){                  //var ewidth        = elem.outerwidth(); //doesn't work in plunker reason                 var ewidth  = '100%';                 var html        = '<div><ul class="list-group" style="position: absolute; width: '+ewidth+'px;"><li class="list-group-item" ng-repeat="codes in cdata track $index">{{codes.code}}</li></ul></div>';                 elem.after($compile(html)(scope));                 scope.$apply();                 console.log("div has been added");             });                scope.$watch(function() {                 return modelget(scope);             }, function() {                 var string = modelget(scope);                 if (string != undefined && string.length >= 6) {                     console.log("will later");                 }              });         }     }

ok, found combination of errors in code makes not work. see below:

  • in link, cdata not on scope, cannot accessed html
  • data contains array , not string, cannot interpolate data="{{stuff}}"
  • instead, need $watch attr.data
  • since add information scope, should new 1 using scope: true

that may it, see fixed plunkr: http://plnkr.co/edit/k9d9h8syaqnw3ukui1xt?p=preview

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
