我将#welcome包裹在一个按钮内,因此点击时会产生效果。该按钮似乎什么都不做,并且由于某种原因,我的元素的初始功能(:悬停)已被禁用。我该如何还原呢?
HTML后跟CSS,然后是JavaScript(这三个都在不同的文件中):

首先,您需要定位button
元素而不是其中包含的p
。现在你把它放在左上方。因此,您为.welcome button
元素创建了css规则,并将所有定位规则从p
移至它。
然后,您将:hover
规则更改为.welcome button
。
最后,在javascript函数中,您需要更改:
document.getElementById("welcome").style.pointer-events = "auto";
到:
document.getElementById("welcome").style.pointerEvents = "auto";
或者:
document.getElementById("welcome").style.setProperty("pointer-events","auto");
否则该连字符将被视为减号。
这是一个演示(你仍然需要定位那些较低的div,我不知道你希望它们看起来如何):

我真的不知道如何回答这个问题,但首先,您需要设置一个根目录。根目录可以使用XAMPP或WAMP或MAMP甚至NANP制作。我更喜欢XAMPP。所有这些程序都是本地网站(用于测试或娱乐)。在"*begin*"
这样的链接中调出空格也不明智。只是不要这样做。而不是使用间隔使用<a href=" <!-- HERE Spaces . . . . . --> ">
,这更好一点了!
对于你的问题,我想我知道解决它的方法,这可能发生的原因是你实际上从未将脚本设置为%20
。因此,如果您创建一个实际的JS函数,它可能会更适合您。如果你不知道如何创建一个函数,那么只需看看我在这篇文章最底部的脚本。
现在让我们进入你的CSS按钮,所以我相信这是。当一个人点击欢迎按钮,然后会出现一个DIV,好的,你需要openUp()
中的2个CLASSES
,所以现在看一下这个脚本,以了解你如何制作正确的样式为此:
CSS
那究竟是做什么的?
此脚本加载一个函数,因此当单击该按钮时,它会将属性更改为<html>
<head>
<title>Your title</title>
<style>
.hidden {
display:none;
}.visible {
display:block;
}
.hovering {color:white;background:black;}
.hovering:hover {color:Black;Background:white;}
</style>
</head>
<body>
<button id="YourButtonID" onclick="show()" class="hovering">Show welcome DIV</button>
<div id="HiddenArea" class="hidden">
<p>This is the hidden area that will be appearing onclick above and close if you click iy again.</p>
</div>
<!-- This is where it begins to be tricky -->
<script>
function onclick() {
document.getElementById('HiddenArea').setAttribute('class', 'visible');
document.getElementById('YourButtonID').setAttribute('onclick', 'hide()');
document.getElementById('YourButtonID').innerHTML == 'Hide';
}
function hide() {
document.getElementById('HiddenArea').setAttribute('class', 'hidden');
document.getElementById('YourButtonID').setAttribute('onclick', 'show()');
document.getElementById('YourButtonID').innerHTML == 'Show';
}
</script>
</body>
</html>
,它也会显示隐藏的DIV和适当的
答案 2 :(得分:0)
从按钮标记中删除p
标记。
<button onclick="openUp()" id="welcome">Click to Begin</button>
我无法添加评论。指针事件似乎与事件侦听器的工作方式不同。希望别人能澄清一下。这对我有用。
修改js中的行,
document.getElementById("welcome").className = "pointer-clicks";
然后添加CSS,
.pointer-clicks{
pointer-events: auto;
}
