如何在angularjs中排序时删除重复值?

标签: javascript html angularjs sorting ng-show

我使用angularjs在html中创建了一个记录表。我面临的问题是在排序时带走重复值。截至目前,我已经在页面加载时采取了重复记录。但是当我尝试按降序对记录进行排序时,我能够再次看到重复的记录。

这是我的HTML:

<!doctype html>
<html ng-app='myApp'>
 <head>
 <title>ng-include directives in AngularJS</title>
 <link href="style.css" rel='stylesheet' type='text/css'>
 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js" type='text/javascript'></script>
 <script src='script.js' type='text/javascript'></script>
 <link rel="stylesheet" href="style1.css" />
 </head>
 <body ng-controller="MyCtrl"> 

 <table border='1'>
 <tr >
 <th ng-click='sortColumn("bucket")' ng-class='sortClass("bucket")'>buckets</th>
 <th ng-click='sortColumn("productCode")' ng-class='sortClass("productCode")'>productCode</th>
 <th ng-click='sortColumn("countOfAllocatedAccount")' ng-class='sortClass("countOfAllocatedAccount")'>countOfAllocatedAccount</th>
 <th ng-click='sortColumn("countOfCollectedAccount")' ng-class='sortClass("countOfCollectedAccount")'>countOfCollectedAccount</th>
  <th ng-click='sortColumn("sumOfArrearsOfAllocatedAmount")' ng-class='sortClass("sumOfArrearsOfAllocatedAmount")'>sumOfArrearsOfAllocatedAmount</th>
   <th ng-click='sortColumn("sumOfCollectedAmount")' ng-class='sortClass("sumOfCollectedAmount")'>sumOfCollectedAmount</th>
 </tr>
 <tr ng-repeat='p in products | orderBy:column:reverse'>
 <td><span ng-show="products[$index-1].bucket != p.bucket" ng-model="sorting">{{p.bucket}}</span></td>                                     
<td><span>{{p.productCode}}</span></td>
<td><span>{{p.countOfAllocatedAccount}}</span></td>
<td><span>{{p.countOfCollectedAccount}}</span></td> 
<td>{{p.sumOfArrearsOfAllocatedAmount | currency:"&#8377;"}}</td>
<td><span>{{p.sumOfCollectedAmount | currency:"&#8377;"}}</span></td>
 </tr>
 </table>

 </body>
</html>

和脚本

var myAppModule = angular.module("myApp", []);
myAppModule.controller("MyCtrl", function($scope,$filter){   

    var jsonData = [
       {
         "bucket": ">120",

如果我在下面正确获取代码可能对您有用。您可以尝试ng-if条件,它将基于反向值显示

 <td>
    <span ng-if="!reverse" ng-show="products[$index-1].bucket != p.bucket" ng-model="sorting">{{p.bucket}}</span>
    <span ng-if="reverse" ng-show="products[$index].bucket != products[$index-1].bucket" ng-model="sorting">{{p.bucket}}</span>
</td>
