javascript - Angularjs ng-click 不更新 View

Question

myApp.controller( 'ModalNewInstanceCtrl', [ '$scope', '$modalInstance', function( $scope, $modalInstance ) {

$scope.tabSelected = 0;

$scope.saveFactor = function () {
    console.log('here');
    $scope.tabSelected = 0;
    console.log($scope.tabSelected);
};

那是我的 Controller 。

    <div class="modal-header">
    <div ng-click="tabSelected = 0">Tab 1</div>
    <div ng-click="tabSelected = 1">Tab 2</div>
    <div ng-click="tabSelected = 2">Tab 3</div>

</div>
<div class="modal-body">
    <div ng-show="tabSelected == 0">
        <h3>Some content 1 here</h3>
    </div><div ng-show="tabSelected == 1">
        <h3>Some content 2 here</h3>
    </div>
    <div ng-show="tabSelected == 2">
        <h3>Some content 3 here</h3>
    </div>
</div>
<div class="modal-footer">
        <button ng-click="saveFactor()">Save and return to tab 1</button>
        <a ng-click="tabSelected = 0">Cancel and return to tab 1</a>
    </div>
</div>

那是我的 html。我不知道为什么tabSelected使用 ng-click="tabSelected = 0" 更新取消链接的 View 直接更改但不在函数内部更改 saveFactor() .我知道由于控制台日志语句，函数被正确调用。和 tabSelected也改变了，但没有改变观点。我不能 $scope.$apply()在那个函数里面，因为它给我一个错误。

更改您的 HTML 以在修改范围变量时使用函数
HTML:

<div class="modal-header">
<div ng-click="changeTab(0)">Tab 1</div>
<div ng-click="changeTab(1)">Tab 2</div>
<div ng-click="changeTab(2)">Tab 3</div>
...
<div class="modal-footer">
    <button ng-click="saveFactor()">Save and return to tab 1</button>
    <a ng-click="changeTab(0)">Cancel and return to tab 1</a>
</div>

JS:

$scope.tabSelected = 0;

$scope.saveFactor = function () {
    console.log('here');
    $scope.tabSelected = 0;
    console.log($scope.tabSelected);
};
$scope.changeTab= function(tabNum){
    $scope.tabSelected = tabNum;
};
