第一个
您可以像这样在选中的单选按钮上隐藏显示容器

<div ng-controller="MyCtrl">
    <input type="radio" ng-model="number" value="0">
    <input type="radio" ng-model="number" value="1">
    <input type="radio" ng-model="number" value="2">    
    <hr> 
    {{value[number]}}
    <div ng-bind-html-unsafe="value[number]"></div> <--if you want bind html than use ng-bind-html-unsafe
</div>

像这样改变你的控制器

function MyCtrl($scope) {
    $scope.number = '0';
    $scope.value = [];
    $scope.value[0]='<div>big container when clicking radiobutton 1</div>'
    $scope.value[1]='<div>big container when clicking radiobutton 2</div>'
    $scope.value[2]='<div>big container when clicking radiobutton 3</div>'
    $scope.$watch('value', function(value) {
       console.log(value);
    });
}
