Question

当我的模型值为true时，我希望在加载时选择单选按钮，但它会在其他位置发生。所有false模型都已被选中。如何解决这个问题。

angular.module('radioExample', [])
      .controller('ExampleController', ['$scope',
        function($scope) {
          $scope.kind = [{
            name: 'task',
            selected: false
          }, {
            name: 'bug',
            selected: false
          }, {
            name: 'other',
            selected: true
          }, {
            name: 'rfe',
            selected: false
          }]
          $scope.$watch('kind', function() {
            console.log('changed', JSON.stringify($scope.kind, null, 2))
          }, true)

        }
      ]);

Answer 1

使用ng-value这里是angular radio

的文档

<input type="radio" name="" id="" value="" ng-model="k.selected" ng-value="true" />

然后，如果ng-value为true且型号值也为true，则会选中复选框

这是update Demo

Answer 2

<input type="checkbox" id="rempass" ng-model="rememberMe" ng-checked="rememberMeUserInfoCheck()" >  $scope.rememberMeUserInfoCheck=function() { return true; }

这对我有用

Answer 3

我修好了弹药plunker

 <form name="myForm" ng-controller="ExampleController">
    <br />all 'false' radio buttons are selected when 'value' is used -------------
    <br />
    <div ng-repeat="k in kind">
      <input type="radio" name="" id="" value="" ng-model="!k.selected" value="k.selected" />{{k.name}}
    </div>
    <br />all radio buttons are selected when 'ng-value' is used -------------
    <br />
    <div ng-repeat="k in kind">
      <input type="radio" name="" id="" value="" ng-model="k.selected" ng-value="k.selected" />{{k.name}}
    </div>
</form>

你做对了....只需要添加一个！所以模型将采用与范围值相反的...因为你使用它们两者我猜它不会伤害你的代码

将 ng-checked =“true”添加到您的电台输入栏

`<input type="radio" ng-model="modelName" name="radioName" value="value1" ng-checked="true">`
