如何在angularJS中获得动态标题.我知道如下所示使用ng-attr-title

<div ng-app="myApp" ng-controller="ctrl">
<div ng-attr-title="{{title}}">Hover me</div>
</div>

而控制器是

var app = angular.module('myApp',[]);
function ctrl($scope){
$scope.title = "I 'm a tooltip!";    
}

这是JSfiddle及其工作原理.我正在尝试的是在启用时有两个不同的标题,而在禁用时有另一个,所以我想在运行时决定进入ng-attr-title的变量,如下所示.

<div ng-app="myApp" ng-controller="ctrl">
<div ng-attr-title="{{message}}">Hover me</div>
</div>

而控制器是

var app = angular.module('myApp',[]);
function ctrl($scope){
$scope.Enabledtitle = "U can click me";
$scope.Disabledtitle = "U cannot click me";
 $scope.message="Enabledtitle";    
}

所以,当我徘徊时,我应该得到工具提示说“你可以点击我”.因此,只需更新范围变量消息,我就可以灵活地在工具提示消息之间切换

这是JSfiddle,我尝试了动态标题,并将“Enabledtitle”作为工具提示,而不是“你可以点击我”.

我怎样才能告诉angular解析{{Enabledtitle}}并给它赋值.

var app = angular.module('myApp',[]);

function ctrl($scope) {
    $scope.Enabledtitle = "U can click me";
    $scope.Disabledtitle = "U cannot click me";
    $scope.message = "Enabledtitle";
}

<script src="http://code.angularjs.org/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="ctrl">
    <div ng-attr-title="{{this[message]}}">Hover me</div>
</div>
