使用json模式和angularjs动态生成表单

我有一个json模式，如下所示：

var schema = {
    "type": "object",
    "properties": {
        "requestedFor": {
            "type": "string"
        },
        "location": {
            "type": "string"
        },
        "shortDescription":{
            "type": "string"
        },
        "description": {
            "type": "string"
        }
    }
};


var options = {
    "fields": {
        "requestedFor": {
            "requestedFor": "text",
            "label": "*Name"
        },
        "location": {
            "type": "text",
            "label": "*Location"
        },
        "shortDescription":{
            "type": "text",
            "label": "Short Description"
        },
        "description": {
            "type": "textarea",
            "label": "Description",
            "rows": 5,
            "cols": 60,
            "label": "",
            "wordlimit": 250
        }
    },
    "form": {
        "attributes": {
            "method": "POST",
            "action": "#",
            "enctype": "multipart/form-data"
        },
        "buttons": {
            "submit": {
                "value": "Submit"
            }
        }
    }
};

var app = angular.module("app", [])
  .directive("wrapper", function($compile, $interval) {
    return {
      scope: {
        directiveName: "="
      },
      link: function(scope, elem, attrs) {
        scope.$watch("directiveName", function() {
          var html = "<" + scope.directiveName + "></" + scope.directiveName + ">";
          elem.html(html);
          $compile(elem.contents())(scope);
        });
      }
    }
  }).controller("addDirectives", function($scope, $interval) {
    let directiveNames = ['d1', 'd2', 'd3', "d4"];
    $scope.directiveName = directiveNames[0];

  }).directive("d1", function() {
    return {
      template: "<input type='text'>Requested For</input>"
    }
  }).directive("d2", function() {
    return {
      template: "<input type='text'>Location</input>"
    }
  }).directive("d3", function() {
    return {
      template: "<input type='text'>Short Description</input>"
    }
  }).directive("d4", function(){
      return {
          template: "<input type='textarea'>Description</input>"
      }
  })

因此，我想使用这个json模式使用angularjs动态创建一个自定义指令。因此，我创建了如下代码：

var schema = {
    "type": "object",
    "properties": {
        "requestedFor": {
            "type": "string"
        },
        "location": {
            "type": "string"
        },
        "shortDescription":{
            "type": "string"
        },
        "description": {
            "type": "string"
        }
    }
};


var options = {
    "fields": {
        "requestedFor": {
            "requestedFor": "text",
            "label": "*Name"
        },
        "location": {
            "type": "text",
            "label": "*Location"
        },
        "shortDescription":{
            "type": "text",
            "label": "Short Description"
        },
        "description": {
            "type": "textarea",
            "label": "Description",
            "rows": 5,
            "cols": 60,
            "label": "",
            "wordlimit": 250
        }
    },
    "form": {
        "attributes": {
            "method": "POST",
            "action": "#",
            "enctype": "multipart/form-data"
        },
        "buttons": {
            "submit": {
                "value": "Submit"
            }
        }
    }
};

var app = angular.module("app", [])
  .directive("wrapper", function($compile, $interval) {
    return {
      scope: {
        directiveName: "="
      },
      link: function(scope, elem, attrs) {
        scope.$watch("directiveName", function() {
          var html = "<" + scope.directiveName + "></" + scope.directiveName + ">";
          elem.html(html);
          $compile(elem.contents())(scope);
        });
      }
    }
  }).controller("addDirectives", function($scope, $interval) {
    let directiveNames = ['d1', 'd2', 'd3', "d4"];
    $scope.directiveName = directiveNames[0];

  }).directive("d1", function() {
    return {
      template: "<input type='text'>Requested For</input>"
    }
  }).directive("d2", function() {
    return {
      template: "<input type='text'>Location</input>"
    }
  }).directive("d3", function() {
    return {
      template: "<input type='text'>Short Description</input>"
    }
  }).directive("d4", function(){
      return {
          template: "<input type='textarea'>Description</input>"
      }
  })

var-app=angular.module（“app”，[]）
.directive（“包装器”，函数（$compile，$interval）{
返回{
范围：{
directiveName:“”
},
链接：功能（范围、要素、属性）{
作用域.$watch（“directiveName”，function（））{
var html=“”；
elem.html（html）；
$compile（elem.contents（））（范围）；
});
}
}
}).controller（“addDirectives”，函数（$scope，$interval）{
设directiveNames=['d1'，'d2'，'d3'，'d4]；
$scope.directiveName=directiveNames[0]；
}).指令（“d1”，函数（）{
返回{
模板：“请求用于”
}
}).指令（“d2”，函数（）{
返回{
模板：“位置”
}
}).指令（“d3”，函数（）{
返回{
模板：“简短描述”
}
}).指令（“d4”，函数（）{
返回{
模板：“说明”
}
})

这里我的意图是使用这个json模式动态生成表单，因为我有太多的json文件可用，所以我需要创建不同的自定义指令

<!DOCTYPE html>
<html ng-app="app">
<head>
<body ng-controller="addDirectives">

    <div class="container">

        <div class="row">
            <div class="col-md-12">

                <div id="form"></div>

            </div>
        </div>
    </div>

</body>
</html>

那么，有人能提供解决方案吗？

看看angular formly和其他已经存在的动态表单模块，我正在使用alpacajs库实现json模式。羊驼不可能吗？
