使用另一个段落中的链接切换段落
我有类似的代码。除了我的 JS 文件是外部的这一事实。函数 myFunction() 在该文件的开头被调用，如下所示：
document.addEventListener('DOMContentLoaded', function () {
myFunction()
})但是，它不起作用 - 当单击第一段中的“此处”一词时，它没有显示第二段中的文本。我想也许我应该以其他方式调用该函数。任何给定的想法都会非常有帮助。谢谢。
PS 此外，单击时，窗口应滚动到新打开的段落。
function myFunction() {
var x = document.getElementById("myCollapsible2")
if (x.style.display === "block") {
x.style.display = "none";
} else {
x.style.display = "block";
}
}
p{
background: #eee;
border: 1px solid #ccc;
margin: 20px 0;
padding: 30px;
}
.bs-example{
margin: 20px;
}
.link-color {
color: red;
}

由于您将 bootstrap 与 popper 一起使用，因此不需要您的函数，只需根据文档设置值即可。要滚动到该元素，请使用scrollIntoView方法。我必须将它包装在 setTimeout 周围，因为默认方法随后执行，所以当我调用滚动时，元素还不可见。function scrollTo2() { var el = document.getElementById('myCollapsible2'); window.setTimeout(() => el.scrollIntoView(), 0);}p { background: #eee; border: 1px solid #ccc; margin: 20px 0; padding: 30px;}.bs-example { margin: 20px;}.link-color { color: red;}<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"><link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script><div class="bs-example"> <input type="button" class="btn btn-primary" data-toggle="collapse" data-target="#myCollapsible" value="Toggle Button"> <div id="myCollapsible" class="collapse show"> <p>This is a simple example of expanding and collapsing individual element via data attribute.<br>Click on the <b>Toggle Button</b> button to see the effect.
