javascript - 如何让AngularJS默认选中一个复选框

Question

当页面在两个切换复选框之间加载时，如何默认选中一个复选框。我的代码:

jsfiddle:http://jsfiddle.net/Lvc0u55v/456/

function MyCtrl($scope) {
    $scope.changeAxis1 = function() {
        if ($scope.thirtyDay) {
                    $scope.wholeTimeline = false;

    }
                };

     $scope.changeAxis2 = function() {
            if($scope.wholeTimeline) {
                    $scope.thirtyDay = false;  

                }
    };
};

查看

 <label class='checkboxes' id='checkbox_1'>
        <input type="checkbox" ng-model="thirtyDay" ng-change="changeAxis1()">
        Two
        </label>
         <label class='checkboxes' id='checkbox_2'>
        <input type="checkbox" ng-model="wholeTimeline" ng-change="changeAxis2()">
        One
        </label>

在 Controller 中将其中一个值初始化为 true:

function MyCtrl($scope) {
    $scope.changeAxis1 = function() {
        if ($scope.thirtyDay) {
            $scope.wholeTimeline = false;
        }
    };

    $scope.changeAxis2 = function() {
         if($scope.wholeTimeline) {
            $scope.thirtyDay = false;  
         }
    };

    $scope.thirtyDay = true;
};

您还需要在 View 中包含 ng-app 和 ng-controller 以便 Angular 执行任何操作:

<div class="checkbox" ng-app="" ng-controller="MyCtrl">
