您好我的application.js ...
中有以下代码段.directive('titleEffect', function($animate){
return function(scope, element, attrs){
scope.$watch(attrs.titleEffect, function(newVal){
$animate.addClass(element, 'title_effect')
})
};
})
.animation('.title_effect', function(){
return{
addClass: function(element, className){
console.log('aaa')
}
})
但是没有触发ng-animation addClass函数,这是我的html:
<h3 title-effect='globalData.currentTitle' > </h3>
其中currentTitle是一个全局数据集:
.run(function($rootScope){
$rootScope.globalData = {currentTitle : ''}
})
答案 0 :(得分:0)
在指令准备好之前,您的监视功能可能会被调用2次。使用您的代码,.title_effect
类已添加,但未添加动画,因为它是在初始化之前添加的,您从未删除过类。您还需要在动画中调用done()
,以便从元素中移除ng-animate
,以便更改动画。
var app = angular.module("app", ["ngAnimate"])
.controller('MainCtrl', function() {
var vm = this;
vm.titleEffect = false;
})
.directive("titleEffect", ["$animate",
function($animate) {
return function(scope, element, attrs) {
scope.$watch(attrs.titleEffect, function(newValue) {
if (newValue) {
$animate.addClass(element, "title_effect");
} else {
$animate.removeClass(element, "title_effect");
}
});
};
}
])
.animation(".title_effect", function() {
return {
addClass: function(element, className, done) {
console.log('add');
TweenMax.to(element, 0.35, {
autoAlpha: 0,
onComplete: done
});
},
removeClass: function(element, className, done) {
console.log('remove');
TweenMax.to(element, 0.35, {
autoAlpha: 1,
onComplete: done
});
}
};
});
