我有一个练习,我必须能够自定义一些笔记本电脑的选项。我正在从数据库中加载此选项。有四种可能的选择:RAM,处理器,视频,屏幕。对于输入模型,我想分别设置ng-model
。
<div class="text-center">
<div class="marginTop">
<p>{{laptop.selected.text}}</p>
<div class="row" ng-repeat="x in laptop.customize">
<div class="col-xs-3">
<p>{{x.name}}</p>
</div>
<div class="col-xs-9">
<label class="radio-inline" ng-repeat="y in x.options">
<input type="radio" name="{{x.name}}" ng-model="laptop.selected.{{x.name}}" ng-value="y.description"> {{y.description}}
</label>
</div>
</div>
<div class="col-xs-12">
<a href="#order" ng-click="laptop.save()" class="btn btn-default" type="submit">En door</a>
</div>
</div>
目标是设置ng-model="laptop.selected.RAM"
或ng-model="laptop.selected.Processor"
,但我找不到任何方法。
请原谅我的HTML,我是个菜鸟。

答案 0 :(得分:1)
您只需这样设置,因为您已经将值保存在y中,您也可以使用ng-change
获取所选值<div class="marginTop">
<p>{{laptop.selected.text}}</p>
<div class="row" ng-repeat="x in laptop.customize">
<div class="col-xs-3">
<p>{{x.name}}</p>
</div>
<div class="col-xs-9">
<label class="radio-inline" ng-repeat="y in x.options">
<input type="radio" name="{{x.name}}" ng-model="laptop.selected[y.name]" ng-change="getselected(y)" ng-value="y.description"> {{y.description}}
</label>
</div>
</div>
<div class="col-xs-12">
<a href="#order" ng-click="laptop.save()" class="btn btn-default" type="submit">En door</a>
</div>
</div>
