角度中的多维数组有问题

What is the issue in my code?

return array is

{"records":
    [{"Status":"1",
    "Date":"2017-07-14 10:46:33",
    "Email":"cy@gmail.com","Company":"Inc.",
    "Model":"Model 8081 A","Animation":"Walk, Turn Around","id":"1",
    "Note":"This is a new request for model with animation.",
    "Attachment":
        "[{'url':'request/31a.jpg','name':'a.jpg'},{'url':'request/42Light.png','name':'Light.png'}]"
}]
}

And HTML code is

<tr ng-repeat="x in records">
    <td>{{x.Status}}</td>
    <td>{{x.Date}}</td>
    <td>{{x.Email}}</td>
    <td>{{x.Company}}</td>
    <td>{{x.Model}}</td>
    <td>{{x.Animation}}</td>
    <td>{{x.Note}}</td>
    <td>
        <table>
        <tr ng-repeat="lnk in x.Attachment">
            <td>{{lnk.url}}</td>
            <td>{{lnk.name}}</td>
        </tr>
        </table>
    </td>          
</tr>

lnk.url and lnk.name print nothing.

Error in console is [ngRepeat:dupes]

Attachment is a string not an array. convert it to an array and it will l work

angular.module("app",[])
.controller("ctrl",function($scope){

  
   $scope.records = [  
      {  
         "Status":"1",
         "Date":"2017-07-14 10:46:33",
         "Email":"cy@gmail.com",
         "Company":"Inc.",
         "Model":"Model 8081 A",
         "Animation":"Walk, Turn Around",
         "id":"1",
         "Note":"This is a new request for model with animation.",
         "Attachment":[{'url':'request/31a.jpg','name':'a.jpg'},{'url':'request/42Light.png','name':'Light.png'}]
      }
   ] 
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
 <table>
  <tr ng-repeat="x in records">
    <td>{{x.Status}}</td>
    <td>{{x.Date}}</td>
    <td>{{x.Email}}</td>
    <td>{{x.Company}}</td>
    <td>{{x.Model}}</td>
    <td>{{x.Animation}}</td>
    <td>{{x.Note}}</td>
    <td>
        <table>
        <tr ng-repeat="lnk in x.Attachment">
            <td>{{lnk.url}}</td>
            <td>{{lnk.name}}</td>
        </tr>
        </table>
    </td>          
</tr>
 </table>
</div>

</div>

Your attachment is not an array, it is a string. Your return array should be like this:

{
  "records": [{
    "Status": "1",
    "Date": "2017-07-14 10:46:33",
    "Email": "cy@gmail.com",
    "Company": "Inc.",
    "Model": "Model 8081 A",
    "Animation": "Walk, Turn Around",
    "id": "1",
    "Note": "This is a new request for model with animation.",
    "Attachment": [{
        "url": "request/31a.jpg",
        "name": "a.jpg"
    }, {
        "url": "request/42Light.png",
        "name": "Light.png"
    }]
  }]
}

(Notice removed quotes in Attachment).

So you should convert Attachment with JSON.parse() function in your controller.
