我正在为未来的项目评估angularjs.我需要做的一件事是通过选择适当的"页面"无线电输入来显示不同的"频道"信息页面.此外,页面按钮的范围也可以从一组"页面设置"无线电输入中选择.
下面的工作示例具有一组32个通道,通过"设置"和"页面"无线电输入的组合选择可见的通道组,每个通道总共提供2*4页的4个通道.

$scope.channels = [

我的问题是如何使用创建页面/页面集无线电输入ng-repeat.我尝试过如下方法:
<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>
看起来正确,但值不绑定到相应的pageSet/pageNumber变量.谁能告诉我在这里缺少什么？

ng-repeat创建子范围,因此您必须绑定到$ parent:
这是一个小提琴:http://jsfiddle.net/g/r9MLe/2/
样品:
<p>Set:
<label ng-repeat="n in [0,1]">
<input type="radio" name="pageSet" ng-model="$parent.pageSet" ng-value="n" />{{n}}
</label>
</p>
<p>Page:
<label ng-repeat="n in [0,1,2,3]">
<input type="radio" name="pageNumber" ng-model="$parent.pageNumber" ng-value="n" /> {{n}}
</label>
</p>
使用JSON中的值有什么问题？
<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>
来自数据:
vm.verifications = [
{
"label" : "Valid last line (USPS only)",
"value" : "vll",
"type" : "optional"
},
{
"label" : "Domestic recipient",
"value" : "dr",
"type" : "optional"
},
];
