{{announcement}
创建一个指令,用于监视属性上的值更改并执行动画 例如:
<p ng-model="announcement">{{announcement}}</p>
用法:
app.directive('flash', ['$animate',
function($animate) {
return {
link: function(scope, element, attrs) {
scope.$watch(attrs.flash, function(newValue, oldValue) {
if (newValue === oldValue) return;
$animate.addClass(element, 'flash').then(function() {
element.removeClass('flash');
});
});
}
};
}
]);
对于第二个版本,您需要观看attrs.ngBind
,而不是attrs.flash
:
<p flash ng-bind="announcement" class="animated"></p>
请注意,此示例使用ngAnimate
和animate.css
执行动画
演示:感谢您的大力帮助
<p flash ng-bind="announcement" class="animated"></p>
scope.$watch(attrs.ngBind, ...
