AngularJS“scrollTop的”等价? [英] AngularJS 'scrollTop' equivalent?
问题描述
我期待实现在AngularJS指令类似于这样:
<一个href=\"https://github.com/geniuscarrier/scrollToTop/blob/master/jquery.scrollToTop.js\">https://github.com/geniuscarrier/scrollToTop/blob/master/jquery.scrollToTop.js
这是相当简单的,当你不在它会在一个按钮淡出滚动到页面顶部的顶部:
$(窗口).scroll(函数(){
如果($(本).scrollTop()→100){
$ this.fadeIn();
}其他{
$ this.fadeOut();
}
});
不过我有一个很难找到如何在角获取当前的滚动位置。我宁愿没有使用jQuery只为这一件事情。
谢谢!
$ window.pageYOffset
这是从服务窗口$属性。
I'm looking to implement something similar to this in an AngularJS directive:
https://github.com/geniuscarrier/scrollToTop/blob/master/jquery.scrollToTop.js
It's fairly straightforward, when you are not at the top of the page it will fade in a button to scroll to the top:
$(window).scroll(function() {
if ($(this).scrollTop() > 100) {
$this.fadeIn();
} else {
$this.fadeOut();
}
});
However I'm having a hard time finding how to get the current scroll location in Angular. I'd rather not have to use jQuery just for this single thing.
Thanks!
$window.pageYOffset
This is property from service $window
