I'm evaluating angularjs for a future project. One of the things I will need to do is display different pages of "channel" information by selecting an appropriate "page" radio input. Furthermore, ranges of page buttons may also be selected from a group of "page set" radio inputs.
The working example below has a set of 32 channels with the visible group of channels being selected via a combination of "set" and "page" radio inputs, giving a total of 2 * 4 pages of 4 channels each.
<!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> My question is how to create the page/page set radio inputs using ng-repeat. I've tried approaches such as:
<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> which looks right, but the values don't bind to the corresponding pageSet/pageNumber variables. Can anyone tell what I'm missing here?

ng-repeat create a child scope, so you have to bind to the $parent:
Here's a fiddle: http://jsfiddle.net/g/r9MLe/2/
Sample:
<p>Set: <label ng-repeat="n in [0,1]"> <input type="radio" name="pageSet" ng-model="$parent.pageSet" ng-value="n" />{{n}} </label> </p> <p>Page: <label ng-repeat="n in [0,1,2,3]"> <input type="radio" name="pageNumber" ng-model="$parent.pageNumber" ng-value="n" /> {{n}} </label> </p> What's wrong with just using a value from the JSON?
<table> <tr ng-repeat="v in partneradd.verifications"> <td>{{v.label}}</td> <td> <div class="radio-inline"> <label> <input type="radio" name="{{v.value}}" value="required"> Required </label> </div> </td> <td> <div class="radio-inline"> <label> <input type="radio" name="{{v.value}}" value="optional"> Optional </label> </div> </td> </tr> </table> from the data:
vm.verifications = [ { "label" : "Valid last line (USPS only)", "value" : "vll", "type" : "optional" }, { "label" : "Domestic recipient", "value" : "dr", "type" : "optional" }, ]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
