我无法在列的排序中显示正确的图标,如果单击一列进行排序,则所有其他列的图标也会更新。
只有排序列才能获得有关各列排序的更新。
我在此处列出了我的代码:http://plnkr.co/edit/UonOgNz0s16iKJkWLwyg?p=preview
<table border="1">
<thead>
<tr>
<th ng-repeat="key in getKeysOfCollection(colors[0])" ng-click="ctrl.predicate = key; ctrl.reverse=!ctrl.reverse;">
{{key}}
<span class="fa fa-sort columnSortIcons" ng-if="ctrl.reverse"></span>
<span class="fa fa-sort-down columnSortIcons" ng-if="!(ctrl.reverse)"></span>
<span class="fa fa-sort-up columnSortIcons" ng-if="ctrl.reverse"></span>
</th>
</tr>
<tr>
<th ng-repeat="key in getKeysOfCollection(colors[0])">
<input type="text" ng-model="search[key]" />
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in colors | filter:search | orderBy:ctrl.predicate:ctrl.reverse">
<td ng-repeat="key in getKeysOfCollection(item)">{{item[key]}}</td>
</tr>
</tbody>
</table>
this.predicate='id';
this.reverse=false;
$scope.search = {};
$scope.colors = [{
'id': 1,
'productId': 1001,
'productName': 'prd 1',
'minimumLevel': 2,
'price': 12.50,
'productDate': '2014-11-01T06:41:30.809Z'
}, {
'id': 2,
'productId': 1002,
'productName': 'prd 2',
'minimumLevel': 23,
'price': 12.54,
'productDate': '2014-11-02T06:41:30.809Z'
}, {
'id': 3,
'productId': 1003,
'productName': 'prd 3',
'minimumLevel': 2,
'price': 12.50,
'productDate': '2014-11-04T06:41:30.809Z'
}, {
'id': 4,
'productId': 1004,
'productName': 'prd 4',
'minimumLevel': 2,
'price': 12.50,
'productDate': '2014-11-22T06:41:30.809Z'
}, {
'id': 5,
'productId': 1005,
'productName': 'prd 5',
'minimumLevel': 2,
'price': 12.50,
'productDate': '2014-11-18T06:41:30.809Z'
}];
$scope.getKeysOfCollection = function(obj) {
obj = angular.copy(obj);
if (!obj) {
return [];
}
return Object.keys(obj);
}
答案 0 :(得分:1)
在ng-if
语句中,您不会检查该列是否为已排序列(谓词):
<span class="fa fa-sort-down columnSortIcons" ng-if="!(ctrl.reverse) && key == ctrl.predicate"></span>
<span class="fa fa-sort-up columnSortIcons" ng-if="ctrl.reverse && key == ctrl.predicate"></span>
更新了code。
