我正在评估一个未来项目的angularjs。我将需要做的事情之一是通过选择适当的“页面”无线电输入显示不同页面的“频道”信息。此外,页面按钮的范围还可以从“页面集合”无线电输入的组中选择。
下面的工作示例具有一组32个通道,其中通过“设置”和“页面”无线电输入的组合来选择可见的频道组,给出总共2×4页,每个4个频道。
<!doctype html> <html ng-app> <head> <script type="text/javascript" src="angular.js"></script> <script type="text/javascript"> function Channels($scope) { $scope.groupSize = 4; $scope.pageSet = 0; $scope.pageNumber = 0; $scope.channels = [ {"id": "Ch-001"},{"id": "Ch-002"},{"id": "Ch-003"},{"id": "Ch-004"},{"id": "Ch-005"},{"id": "Ch-006"},{"id": "Ch-007"},{"id": "Ch-008"},{"id": "Ch-009"},{"id": "Ch-010"},{"id": "Ch-011"},{"id": "Ch-012"},{"id": "Ch-013"},{"id": "Ch-014"},{"id": "Ch-015"},{"id": "Ch-016"},{"id": "Ch-017"},{"id": "Ch-018"},{"id": "Ch-019"},{"id": "Ch-020"},{"id": "Ch-021"},{"id": "Ch-022"},{"id": "Ch-023"},{"id": "Ch-024"},{"id": "Ch-025"},{"id": "Ch-026"},{"id": "Ch-027"},{"id": "Ch-028"},{"id": "Ch-029"},{"id": "Ch-030"},{"id": "Ch-031"},{"id": "Ch-032"} ]; } </script> </head> <body ng-controller="Channels"> <p>Set: <input type="radio" name="pageSet" ng-model="pageSet" ng-value="0">1-4</input> <input type="radio" name="pageSet" ng-model="pageSet" ng-value="1">5-8</input> </p> <p>Page: <input type="radio" name="pageNumber" ng-model="pageNumber" ng-value="0">{{pageSet * groupSize + 1}}</input> <input type="radio" name="pageNumber" ng-model="pageNumber" ng-value="1">{{pageSet * groupSize + 2}}</input> <input type="radio" name="pageNumber" ng-model="pageNumber" ng-value="2">{{pageSet * groupSize + 3}}</input> <input type="radio" name="pageNumber" ng-model="pageNumber" ng-value="3">{{pageSet * groupSize + 4}}</input> </p> <ul> <li ng-repeat="channel in channels | limitTo: groupSize * ((groupSize * pageSet) + pageNumber + 1) | limitTo: -groupSize"> <p>{{channel.id}}</p> </li> </ul> </body> </html>
我的问题是如何使用ng-repeat创建页面/页面集无线电输入。我尝试过的方法,如:
<p>Set: <input ng-repeat="n in [0,1]" type="radio" name="pageSet" ng-model="pageSet" ng-value="{{n}}"></p> <p>Page: <input ng-repeat="n in [0,1,2,3]" type="radio" name="pageNumber" ng-model="pageNumber" ng-value="{{n}}"></p>
这看起来是正确的,但是值不绑定到相应的pageSet / pageNumber变量。谁能告诉我在这里失踪?
ng-repeat创建一个子范围,所以你必须绑定到$ parent:

样品:
<p>Set: <label ng-repeat="n in [0,1]"> <input type="radio" name="pageSet" ng-model="$parent.pageSet" ng-value="n" />{{n}} </label> </p> <p>Page: <label ng-repeat="n in [0,3]"> <input type="radio" name="pageNumber" ng-model="$parent.pageNumber" ng-value="n" /> {{n}} </label> </p>
