在Angularjs中显示输出时删除重复名称
提问于 2016-10-27 17:11:23
我有一个json (在我的控制器中)，如下所示
//creating an application module
var myAppModule = angular.module("myApp", []);
myAppModule.controller("MyCtrl", function($scope, $http){
var jsonData = [
{
"bucket": ">120",
"productCode": "SBML",
"countOfAllocatedAccount": 640
},
{
"bucket": ">120",
"productCode": "SBHL",
"countOfAllocatedAccount": 1391
},
{
"bucket": "1-30",
"productCode": "SBHL",
"countOfAllocatedAccount": 1081
},
{
"bucket": "1-30",
"productCode": "SBML",
"countOfAllocatedAccount": 408
},
{
"bucket": "1-30",
"productCode": "SBML",
"countOfAllocatedAccount": 998
},
{
"bucket": "X",
"productCode": "SBML+",
"countOfAllocatedAccount": 93
}
];
$scope.products = jsonData;
});//end controller和我的观点(index.html)如下
<body ng-app="myApp">
<div ng-controller="MyCtrl" align="center">
<table border="1">
<tr>
<th>Bucket</th>
<th>PRODUCT_CODE</th>
<th>Allocated #</th>
</tr>
<tr ng-repeat="p in products">
<td><span>{{p.bucket}}</span></td>
<td><span>{{p.productCode}}</span></td>
<td><span>{{p.countOfAllocatedAccount}}</span></td>
</tr>
</table>
</div>
</body>
</html>当前输出为
但是我正在寻找下面的输出

你可以做这样的事情。
将当前存储桶值与前一个存储桶值进行比较，如果它们相同，则不显示。
<tr ng-repeat="p in products">
<td><span ng-show="products[$index-1].bucket != p.bucket">{{p.bucket}}</span></td>
<td><span>{{p.productCode}}</span></td>
<td><span>{{p.countOfAllocatedAccount}}</span></td>
</tr> 您可以在此处查看结果JSBIN
