Question

<div class="btn-group dd-rm-action" role="group" aria-label="...">
    <button type="button" class="btn btn-primary dd-action pagination-centered" ng-click="Save()">Save</button>
    <button class="btn btn-default dd-action dropdown-toggle" type="button" id="dropdownState" data-toggle="dropdown" aria-expanded="true" ng-bind="rmCW.State.Name">
        <b class="caret"></b>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownState">
        <li role="presentation" ng-repeat="task in docState.Tasks">
            <a role="menuitem" tabindex="{{$index}}" href="#" ng-click="execTask(task)">{{task.Name}}</a>
        </li>
    </ul>
</div>

我有一个 angularjs 应用程序，它工作正常，只是更新范围值后按钮的 ng-bind 不会更新:

result.then(function (r) {
    $scope.$emit('UNLOAD');
    if (r.status == 0) {
        var cs = JSON.parse(r.data)
        $scope.docState = cs;
        $scope.rmCW.Current = cs;
    }
}

Answer 1

很可能是因为 ng-bind="rmCW.State.Name" 并且您的范围设置为其他属性。

 $scope.rmCW.Current = cs;

您需要将 ng-bind 设置为 ng-bind="rCW.Current.Name"，或者需要将 $scope 设置为 $scope.rmCW.State = .cs;
