javascript - How to access form object with two-way-binding in angular directive without isolated scope -


as titled, given following simple example:

<form name="myform">   <button my-directive-test="myform">hello</button> </form>  app.directive('my-directive-test', function() {  return {    restrict:'a',    link: function(scope, element, attrs) {        // how scope.myform.$submitted, scope.myform.$errors without isolated scope?    })  }; });

currently have been doing is:

<form name="myform">   <button my-directive-test="{{myform.$submitted}}">hello</button> </form>  app.directive('my-directive-test', function() {  return {    restrict:'a',    link: function(scope, element, attrs) {      scope.formsubmitted = scope.$eval(attrs.mydirectivetest);      if (scope.formsubmitted) {      } else {      }    })  }; });

but achieve is:

<form name="myform">   <button my-directive-test="myform">hello</button> </form>  app.directive('my-directive-test', function() {  return {    restrict:'a',    link: function(scope, element, attrs) {      if (scope.myform.$submitted) {      } else {      }    })  }; });

but far haven't found way bind form object in directive.

when not using isolated scope, directive scope same "parent" element's scope. work:

<form name="myform">   <button my-directive-test="myform">hello</button> </form>  app.directive('mydirectivetest', function() {  return {    restrict:'a',    link: function(scope, element, attrs) {      if (scope[attrs.mydirectivetest].$submitted) {      } else {      }    })  }; });

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.
