Question

//Here is the HTML code
<div ng-controller="getuserById" userid="{{ques.created_by}}" >
</div>

//Here is the Controller   
obj.controller('getuserById', function ($scope, $http,$attrs) {
    console.log($attrs.userid);
    $http.get("some_url_here?attr1="+$attrs.userid)
    .success(function(data){
        $scope.user = data;
     })
    .error(function() {
        $scope.user = "error in fetching data";
     });
 });

从上面的代码中，当我将硬代码放在userid属性中然后它在动态数据中工作时它不会那么告诉我如何解决它？

Answer 1

用户ng-model代替。这是修改后的代码。

 <div ng-controller="getuserById" ng-init="userid=ques.created_by" >
 </div>

使用Javascript：

obj.controller('getuserById', function ($scope, $http) {

$http.get("some_url_here?attr1="+$scope.userid)
  .success(function(data){
      $scope.user = data;
   })
  .error(function() {
      $scope.user = "error in fetching data";
   });
 });

Answer 2

//这是HTML

<div getuserbyid value="{{ques.created_by}}" > </div>

//这是我在下面使用的指令

obj.directive('getuserbyid', function ($http) {
    return function (scope, element, attr) {
    attr.$observe('value', function(actual_value) {
    element.val("value = "+ actual_value);
})
console.log(attr.value);

$http.get("some_url_here?attr1="+attr.value)
    .success(function(data){
    scope.user = data;
})
.error(function() {
   scope.user = "error in fetching data";
});

}

}）;

//上面的代码工作正常：）
