指令中的編譯函數沒有正確評估

Question

我有一個叫做validate的指令會跨越表單並根據內置的角度輸入驗證指令自動驗證表單。該指令的一部分工作是循環顯示錶單上的子輸入，併爲數據驗證添加適當的工具提示。這發生在指令的編譯部分。問題是我在編譯函數中設置的數據綁定不在html中計算。例如

app.directive('validate', ["$timeout", "$compile", "gsap", function ($timeout, $compile, gsap) { 
    return { 
     scope: { 
      name: "@" 
     }, 
     restrict: 'E', 
     replace: true, 
     controller: function ($scope) { 
     $scope.validate = {}; 
     }, 
     template: '<form name="{{name}}" ng-transclude></form>', 
     transclude: true, 
     compile: function compile(element, attr) { 

      //wrap this in a timeout function and wait for children to be available 
      //Have also tried this in the postLink function to the same result 

      $timeout(function() { 
       var selective = element.find('.validate'); 

       if (selective.length > 0) { 
        $.each(selective, function (k, v) { 
         v.attr({ 
          "tooltip": '{{validate.' + $(v).attr("name") + '}}', 
           "tooltip-trigger": '{{{true: "invalid", false: "valid"}[{{name}}.' + $(v).attr("name") + '.$invalid]}}' 
         }); 
        }); 
       } else { 
        $.each(element.find('input'), function (k, v) { 
         $(v).attr({ 
          "tooltip": '{{validate.' + $(v).attr("name") + '}}', 
           "tooltip-trigger": '{{{true: "invalid", false: "valid"}[{{name}}.' + $(v).attr("name") + '.$invalid]}}' 
         }); 
        }); 
       } 
      }); 

      return { 

       post: function postLink(scope, elem, attr, controller) { 


        //...a whole bunch of validation code, all works fine... 
        //should compile with attributes and resolved databindings 

        $compile(scope, elem, attr, controller); 
       } 
      }; 
     } 

    }; 
}]); 

這種評估在我的DOM

<input ng-model="username" type="email" placeholder="Username" name="username" ng-required="true" ng-minlength="2" class="ng-pristine ng-invalid ng-invalid-required ng-valid-email ng-valid-minlength" required="required" tooltip="{{validate.username}}" tooltip-trigger="{{{true: &quot;invalid&quot;, false: &quot;valid&quot;}[{{name}}.username.$invalid]}}"> 

正如你看到的，屬性設置以下，但數據綁定不評價，因爲我會指望他們

修正了它。對於任何好奇的人，編譯函數的語法是$compile(elem)(scope)我忘記了編譯的範圍。
