javascript - Angular .js :13920 Error: [ngRepeat:dupes] Duplicates in a repeater

Question

尝试读取以下 json 和 html 中的映射时出现以下错误

js:

searhController.orderlogs.results = JSON.stringify(response.data);

Angular :

<tr ng-hide="searhController.searching" ng-repeat="log in searhController.orderlogs.results">
                    <td>{{log.idTransaction}}</td>
                   <!-- <td>{{log.amount}}</td>
                    <td>{{log.clientName}}</td>
                    <td>{{log.created}}</td>
                    <td>{{log.currency}}</td>
                    <td>{{log.discountedAmount}}</td>
                    <td>{{log.lastUpdate}}</td>
                    <td>{{log.orderId}}</td> -->
                </tr>

JSON:

 [{"idTransaction":2081101,"amount":34990.0,"clientName":"Payment hub","created":"ene 12, 2015","currency":"CLP","discountedAmount":34990.0,"lastUpdate":"ene 12, 2015","orderId":"1421094905114","productDescription":"total: 1 item(s)","fop":{"nameFop":"CAT_FAKE"},"application":{"idApplication":10001,"nameApplication":"TEST APPLICATION"},"transactionStatus":{"nameTransactionStatus":"Waiting for reply"},"transactionByFop":{"settled_amount":0.0,"installments_amount":0.0,"installments_number":0}}]

错误:

angular.js:13920 Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: log in searhController.orderlogs.results, Duplicate key: string:a, Duplicate value: a

您的 JSON 无效，您应该正确格式化它，因为它不是那么小——单行是非常糟糕的。

这是有效的:

{  
   "transaction":{  
      "idTransaction":2081101,
      "amount":34990.0,
      "clientName":"Payment hub",
      "created":"ene 12, 2015",
      "currency":"CLP",
      "discountedAmount":34990.0,
      "lastUpdate":"ene 12, 2015",
      "orderId":"1421094905114",
      "productDescription":"total: 1 item(s)",
      "fop":{  
         "nameFop":"CAT_FAKE"
      },
      "application":"",
      "idApplication":10001,
      "nameApplication":"TEST APPLICATION"
   },
   "transactionStatus":{  
      "nameTransactionStatus":"Waiting for reply"
   },
   "transactionByFop":"",
   "settled_amount":0.0,
   "installments_amount":0.0,
   "installments_number":0
}

我做了什么？

你有两个空属性，它们没有填充任何数据并且破坏了你的 JSON，比如:

[INVALID] "attr1" : "attr2" : "valueOfAttr2",
[VALID]   "attr1" : "", "attr2":"valueOfAttr2" 

并且您有多个 Root 元素，因此它不是有效的 JSON。 尝试使用正确的数据并测试它是否有效。
