如何在Angularjs中使用orderBy将字母显示为表中的第一条记录？

Question

Hi everyone i'm working on angularjs to display list of records in table . The difficulty i'm facing is to display the table in ascending order, i have used the alphabet record (X) which i need to display has the first record in the table.

Let me give you the html page.

<table class="table table-bordered">
    <thead>
        <tr>
            <th ng-click="sort('bucket')" th-sort by="order">Bucket<span class="sortorder descending" ng-hide="(sortKey=='bucket' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='bucket' && reverse==false)"></span>
            </th>
            <th ng-click="sort('productCode')" th-sort by="order">Product Code<span class="sortorder descending" ng-hide="(sortKey=='productCode' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='productCode' && reverse==false)"></span>
            </th>
            <th ng-click="sort('countOfAllocatedAccount')" th-sort by="order">Allocated
                <span class="sortorder descending" ng-hide="(sortKey=='countOfAllocatedAccount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='countOfAllocatedAccount' && reverse==false)"></span>
            </th>
            <th ng-click="sort('countOfCollectedAccount')" th-sort by="order">Collected
                <span class="sortorder descending" ng-hide="(sortKey=='countOfCollectedAccount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='countOfCollectedAccount' && reverse==false)"></span></th>
            <th ng-click="sort('sumOfArrearsOfAllocatedAmount')" th-sort by="order">Total Allocated Amount
                <span class="sortorder descending" ng-hide="(sortKey=='sumOfArrearsOfAllocatedAmount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='sumOfArrearsOfAllocatedAmount' && reverse==false)"></span>
            </th>
            <th ng-click="sort('sumOfCollectedAmount')" th-sort by="order">Total Collected Amount
                <span class="sortorder descending" ng-hide="(sortKey=='sumOfCollectedAmount' && reverse==true)"></span>
                <span class="sortorder" ng-hide="(sortKey=='sumOfCollectedAmount' && reverse==false)"></span></th>
        </tr>
    </thead>
    <tbody>
        <tr ng-repeat="item in view_data">
            <td><span ng-hide="view_data[$index-1].bucket == item.bucket">{{item.bucket}}</span></td>
            <td>{{item.productCode}}</td>
            <td>{{item.countOfAllocatedAccount}}</td>
            <td>{{item.countOfCollectedAccount}}</td>
            <td><span>{{item.sumOfArrearsOfAllocatedAmount | currency:"&#8377;"}}</span></td>
            <td>{{item.sumOfCollectedAmount | currency:"&#8377;"}}</td>
        </tr>
    </tbody>
</table>

And let me show you the output :

And here is my jsfiddle : http://jsfiddle.net/CvKNc/152/

As shown in the image the bucket value X is in the last value in the table. But, i need display it in the first row of the table and rest numbers should be set in the ascending order. I'm stuck here, Please anyone help me with this.

 //creating an application module var myAppModule = angular.module("myApp", []); myAppModule.controller("MyCtrl", function($scope, $http,$filter){ 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 = $filter('orderByValue')(jsonData); });//end controller myAppModule.filter('orderByValue', function() { return function(items, field) { var filtered = [],filteredX = []; angular.forEach(items, function(item) { if(item.bucket=="X") { filteredX.splice(0, 0, item); }else if(item.bucket.indexOf(">") !== -1) { filtered.push(item); }else { filteredX.push(item); } }); angular.forEach(filtered, function(item) { filteredX.push(item); }); return filteredX; }; });
