How to disable scrolling until animation is complete?
提问by Sven
I am using this code to scroll to a certain element on my page:
我正在使用此代码滚动到我页面上的某个元素：
$("html, body").animate({scrollTop: $(".myDiv").offset().top}, 300);
It works, but there is one issue with it: When the user scrolls down while the script scrolls up, there is some juddering because there are two scroll commands at the same time in different directions - sounds logical to me.
它有效，但有一个问题：当用户向下滚动而脚本向上滚动时，会出现一些颤抖，因为在不同方向同时有两个滚动命令 - 对我来说听起来很合乎逻辑。
I checked some other sites with such scroll functionality, there is no juddering. So what's the trick to prevent this?
我检查了其他一些具有这种滚动功能的网站，没有颤抖。那么有什么技巧可以防止这种情况呢？

Thats a jQuery bug when you use animate with scrolling, good detection.
当您使用带有滚动的动画时，这是一个 jQuery 错误，良好的检测。
I did a research how to turn it off scrolling and find this question : How to disable scrolling temporarily?
我做了一项研究如何关闭滚动并找到这个问题：如何暂时禁用滚动？
Here is jsFiddle. You will see after click; user cant scroll untill animate complete.
这是jsFiddle。点击后你会看到；用户无法滚动，直到动画完成。
$('.myDiv').click(function(){
disable_scroll();
$('html, body').stop().animate({ scrollTop: 0 }, 700,function() {
enable_scroll();
});
});

an idea - try hooking to the scroll event and use http://api.jquery.com/stop/to stop your animation .. bad idea..
一个想法 - 尝试挂钩滚动事件并使用http://api.jquery.com/stop/来停止你的动画..坏主意..
same problem with a solution - let user scrolling stop jquery animation of scrolltop?
解决方案的相同问题 -让用户滚动停止滚动顶部的 jquery 动画？
