angularjs指令 - 獲取元素綁定的文本內容

Question

如何根據角度js指令獲取綁定的值restrict: 'A'？

<span directiverestrict> {{binding}} </span> 

我試圖使用elem[0].innerText但它返回結合

.directive('directiverestrict',function() { 
    return { 
     restrict:'A', 
     link: function(scope, elem, attr) { 
      // I want to get the value of the binding enclosed in the elements directive without ngModels 
      console.log(elem[0].textContent) //----> returns '{{binding}}' 
     } 
    }; 
}); 

Answer 1

<span directiverestrict bind-value="binding"> {{binding}} </span> 

的確切結合'{{binding}}'不是值SCRIPT

directive("directiverestrict", function() { 
    return { 
      restrict : "A", 
      scope : { 
         value : '=bindValue' 
        }, 
      link : function (scope,ele,attr) { 
       alert(scope.value); 
       } 
     } 
});

在鏈接階段內綁定沒有評估，最簡單的方法就是使用$timeout服務延遲的內部評價內容下一消化週期，如

$timeout(function() { 
    console.log(elem[0].textContent); 
},0); 

Answer 3

可以使用$interpolate服務，例如

.directive('logContent', function($log, $interpolate) { 
    return { 
    restrict: 'A', 
    link: function postLink(scope, element) { 
     $log.debug($interpolate(element.text())(scope)); 
    } 
    }; 
});
