我没有完全得到ng-switch。这就是我想做的：我的身体有一个可以根据我点击的按钮改变的类。
<body class="green">
....
<button onclick="document.body.className='green'">green</button>
<button onclick="document.body.className='blue'">blue</button>
想法是我需要通过 ng-include 包含一个文本，我希望它是
<div ng-include="green.html"></div> //if body has class green
<div ng-include="blue.html"></div> //if body has class blue
我知道我可以用ng-switch做到这一点，但我不知道怎么做。
你能帮帮我吗？
我认为你可以使用它：
<button ng-click="updateBodyClass('green')">green</button>
<button ng-click="updateBodyClass('blue')">blue</button>
<div ng-switch on="bodyClass">
<div ng-include="green.html" ng-switch-when="green"></div> //if body has class green
<div ng-include="blue.html" ng-switch-when="blue"></div> //if body has class blue
</div>
//inside your controller
$scope.updateBodyClass = function(color) {
document.body.className = color;
$scope.bodyClass = color;
};
试试这个希望这可以工作
<button ng-click="color='green'">green</button>
<button ng-click="color='blue'">blue</button>
<div>
<div ng-include="green.html" ng-if="color==green"></div> //if body has class green
<div ng-include="blue.html" ng-if="color==blue"></div> //if body has class blue
</div>
较短的版本：
<button ng-click="flag='green'">green</button>
<button ng-click="flag='blue'">blue</button>
<div ng-switch on="flag">
<div ng-include="green.html" ng-switch-when="green"></div>
<div ng-include="blue.html" ng-switch-when="blue"></div>
</div>
我希望它有所帮助。
