解决方法
如果您在单击bootstrap下拉菜单的任何选项时更新路线,那么您可以只注意路线更改事件：
<a class="dropdown-toggle">
Click me for a dropdown,yo!
</a>
<ul class="dropdown-menu">
<li ng-repeat="choice in items" class="ng-scope">
<a class="ng-binding">The first choice!</a>
</li><li ng-repeat="choice in items" class="ng-scope">
<a class="ng-binding">And another choice for you.</a>
</li><li ng-repeat="choice in items" class="ng-scope">
<a class="ng-binding">but wait! A third!</a>
</li>
</ul>
$scope.$on('$routeUpdate',function(scope,next,current) {
$('html').trigger('click');
});
上面的方法是有效的,但绝对不需要在每次路由更改时抓取html元素(因为它会导致重排),所以最好把它放在指令中,如下所示：
<html hide-dropdown>
angular.module('App',[]).
directive('hideDropdown',function() {
return {
restrict: 'A',link: function(scope,element) {
scope.$on('$routeUpdate',current) {
element.trigger('click');
});
}
}
});
