使用jQuery平滑滚动导航会导致奇怪的行为 [英] Navigation with jQuery smooth scroll causes weird behavior
本文介绍了使用jQuery平滑滚动导航会导致奇怪的行为的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在我的网站上有一个导航，该导航由jQuery驱动，可以平滑滚动到目标ID，但它的行为很奇怪(Chrome，Firefox):
- 有时它并不会完全移动到目标ID
- 如果您第二次单击目标，它将滚动回到标题
此处 是一个gif，表明我的这种奇怪行为网站.
我制作了 简单版本 我的网站，以便您可以自己进行测试，在这里您可以体验到相同的 奇怪的行为 .
我使它尽可能相同. HTML，类，ID和jQuery 完全相同.我还给导航设置了fixed位置，就像我网站上的位置一样.
有问题的jQuery代码:
$("#scrollOne").click(function() {
$('html,body').animate({
scrollTop: $("#one").offset().top
}, 750);
});
简而言之，导致这种奇怪行为的代码有什么问题?我是否为jQuery使用了错误的方法，如果是，是否有更好的方法?我不介意使用图书馆，但我不想.
解决方案
这是一个有效的版本.显然，这是由于body的CSS规则中的overflow-x:hidden引起的.参见此问题. >
删除了该规则，现在看起来非常好(或者更喜欢下面的代码笔，因为SO的整版版本可能会出现一些问题):
$("#scrollOne").click(function() {
$('html,body').animate({
scrollTop: $("#one").offset().top
}, 750);
});
$("#scrollTwo").click(function(e) {
$('html,body').animate({
scrollTop: $("#two").offset().top
}, 750);
});
$("#scrollThree").click(function() {
$('html,body').animate({
scrollTop: $("#three").offset().top
}, 750);
});
$("#scrollFour").click(function() {
$('html,body').animate({
scrollTop: $("#four").offset().top
}, 750);
});

不相关:我还建议在每个.animate()调用之前添加.stop()，以便每个新动画都停止上一个动画.
I have a navigation on my website that is powered by jQuery to smooth-scroll to the target ID, but it is acting very strange (Chrome, Firefox):
- Sometimes it doesn't actually move to the target ID all the way
- If you click a second time on the target it scrolls you back up to the header
Here is a gif demonstrating this weird behavior on my website.
I made a simplistic version of my website so you can test it yourself, where you can experience the same weird behavior.
I made it as identical as possible. The HTML, classes, ID's and jQuery are exactly the same. I also gave the navigation a fixed position, just like the one on my website.
The jQuery code in question:
$("#scrollOne").click(function() {
$('html,body').animate({
scrollTop: $("#one").offset().top
}, 750);
});
In short, what could the problem be with code that would cause this strange behavior? Am I using the wrong method for jQuery and if so, is there a better one? I don't mind using a library, but I'd prefer not to.
解决方案
Here's a working version. Apparently this is due to the overflow-x:hidden from body's CSS rule. See this question.
Removed that rule, now it seems perfectly fine (or prefer the codepen below that, since SO's fullpage version is bugging out a bit):
$("#scrollOne").click(function() {
$('html,body').animate({
scrollTop: $("#one").offset().top
}, 750);
});
$("#scrollTwo").click(function(e) {
$('html,body').animate({
scrollTop: $("#two").offset().top
}, 750);
});
$("#scrollThree").click(function() {
$('html,body').animate({
scrollTop: $("#three").offset().top
}, 750);
});
$("#scrollFour").click(function() {
$('html,body').animate({
scrollTop: $("#four").offset().top
}, 750);
});
