我已经设置了一个json,其中包含附有ID和国家/地区代码的国家/地区列表:
看起来像这样:
$scope.countries = [
{"name":"Afghanistan","id":"AFG","country-code":"004"},
{"name":"Åland Islands","id":"ALA","country-code":"248"},
{"name":"Albania","id":"ALB","country-code":"008"},
{"name":"Algeria","id":"DZA","country-code":"012"}
]
然后我使用ng-repeat
指令为每个国家/地区创建复选框输入。
<div ng-repeat="country in countries">
<label><input type="checkbox" ng-model="{{country.id}}" ng-true-value="'{{country.name}}'" ng-false-value="''">{{country.name}}</label>
</div>
但是,当我运行代码时,我只会显示以下内容:
地点
复选框{{country.name}}
如果我删除重复的ng-model
部分我的复选框生成正常但我需要将唯一的ng-model
附加到每个复选框
ng-model="{{country.id}}"
我如何附加唯一的ng-model
值?
此答案(Generate ng-model inside ng-repeat)未提供唯一的ng-model
值
答案 0 :(得分:24)
我会建议你,使用:
<div ng-repeat="country in countries">
<label><input type="checkbox" ng-model="myCountry.selected[country.id]" ng-true-value="'{{country.name}}'" ng-false-value="''">{{country.name}}</label>
</div>
</div>
{{myCountry.selected}}
JS:
$scope.myCountry = {
selected:{}
};
