Javascript 使用VisualStudio代码的jquery平滑滚动
我正在尝试在我的网页上使用jquery设置平滑滚动 我在这里以这个例子为例: 当我将其复制并粘贴到js fiddle中时,效果很好。但出于某种原因,我的网站根本不起作用。如您所见,我已将scripts.js文件链接到index.html,并在控制台中通过console.log消息检查了这一点 这是我的html:Javascript 使用VisualStudio代码的jquery平滑滚动,javascript,jquery,html,smooth-scrolling,Javascript,Jquery,Html,Smooth Scrolling,我正在尝试在我的网页上使用jquery设置平滑滚动 我在这里以这个例子为例: 当我将其复制并粘贴到js fiddle中时,效果很好。但出于某种原因,我的网站根本不起作用。如您所见,我已将scripts.js文件链接到index.html,并在控制台中通过console.log消息检查了这一点 这是我的html: !DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> &l

有人知道我做错了什么吗?问题在于你把JS文件的链接放在了头上。把它放在身体底部,它就会起作用
始终将指向JS文件的链接放在正文的结束标记之前。这是因为您可能在头部添加了脚本,并且在头部执行脚本后加载了文档。要使脚本正常工作,您应该将其添加到正文底部,或者添加一个脚本来检查文档是否准备就绪,就像我在这里的代码片段中所做的那样:
$(“文档”).ready(…
在加载文档后加载脚本。请添加项目的结构好吗?
// Select all links with hashes
$('a[href*="#"]')
// Remove links that don't actually link to anything
.not('[href="#"]')
.not('[href="#0"]')
.click(function(event) {
// On-page links
if (
location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '')
&&
location.hostname == this.hostname
) {
// Figure out element to scroll to
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
// Does a scroll target exist?
if (target.length) {
// Only prevent default if animation is actually gonna happen
event.preventDefault();
$('html, body').animate({
scrollTop: target.offset().top
}, 1000, function() {
// Callback after animation
// Must change focus!
var $target = $(target);
$target.focus();
if ($target.is(":focus")) { // Checking if the target was focused
return false;
} else {
$target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
$target.focus(); // Set focus again
};
});
}
}
});
