Angularjs 带有默认值的复选框

我想在init上有一个复选框。这是我的HTML：

<form ng-submit="submit()" name="orderForm" novalidate>
  <input type="radio" id="service-professional" name="service-type" value="Professional" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
  <input type="radio" id="service-premium" name="service-type" value="Premium" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
</form>

我在

$scope.orderForm.serviceType

中尝试了很多东西，但为了我的缘故，我想不出来

您能解释一下如何将Premium设置为默认选中选项吗？谢谢

试试这个：

$scope.orderForm = {
  serviceType: 'Professional'
};

---

以下方面应起作用：

// initializes the form
$scope.orderForm = {};

$scope.orderForm.serviceType = 'Premium';

您只需使用此->
ng checked=“您的_模型==‘您的价值’”

---

您需要使用ng init为复选框范围设置默认值 例如：在html中添加ng init=“scopeName=”value'，然后在复选框ng model和ng checked中使用它scopeName

参见下面的代码

<form ng-submit="submit()" name="orderForm" novalidate ng-init="orderForm.serviceType="1">
    <input type="checkbox" id="service-professional" name="service-type" value="Professional" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
    <input type="checkbox" id="service-premium" name="service-type" value="Premium" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
</form>

<input type="radio" id="service-professional" name="service-type" ng-true-value="1" value="Professional" ng-false-value="0" ng-checked="orderForm.serviceType == 'Professional'" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
<input type="radio" id="service-premium" ng-true-value="1" ng-false-value="0" ng-checked="orderForm.serviceType == 'Premium'" name="service-type" value="Premium" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />

<form ng-submit="submit()" name="orderForm" novalidate ng-init="orderForm.serviceType="1">
    <input type="checkbox" id="service-professional" name="service-type" value="Professional" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
    <input type="checkbox" id="service-premium" name="service-type" value="Premium" class="service-input" ng-model="orderForm.serviceType" ng-change="setService(value)" />
</form>
