问题描述
我想使用标签来隐藏和显示ng-repeat中的项目.是否可以像这样更改范围的值?
I would like to use tabs to hide and show items in an ng-repeat. Is it possible to change the value of a scope like so?
<a ng-click="packageType = '1'">Package 1</a><a ng-click="packageType ='2'">Package 2</a><a ng-click="packageType = '3'">Package 3</a>
<div ng-repeat="item in packages" ng-show="packageType >=item.packageID">
{{item.name}}</div>
和范围:
$scope.packages = [...{ "name": "some name",
"packageID": 1}...]
packageID可以是1、2还是3?
Where packageID can be 1, 2 or 3?
