Html新手在这里..
我正在尝试实现一个网页,弹出一些选定技术词汇的含义,如下所示。我有一个单词列表,其含义以csv格式提供。如何从列表中自动选择可用单词列表的含义?
<!DOCTYPE html>
<html>
<head>
<style>
.dropbtn {
}
.dropbtn:hover, .dropbtn:focus {
background-color: #3e8e41;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
overflow: auto;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {background-color: #f1f1f1}
.show {display:block;}
</style>
</head>
<body>
<h2></h2>
<p>Hands-On with <div class="dropdown">
<button id="myBtn" class="dropbtn">Ultrahaptics'</button>
<div id="myDropdown" class="dropdown-content">
<a href="#home">Feel of touch without wearing devices</a>
</div>
</div>
gave us a feel of technology of future.
</p>
<script>
// Get the button, and when the user clicks on it, execute myFunction
document.getElementById("myBtn").onclick = function() {myFunction()};
/* myFunction toggles between adding and removing the show class, which is used to hide and show the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
}
</script>
</body>
</html>
PS:像
这样的事情<a title="Feel of touch without wearing devices">Ultrahaptics'</a>
仅适用于鼠标指针,不适用于触摸设备。因此,寻找适用于触摸设备的解决方案。

我可以看到你使用的是javascript。我建议使用jQuery-CSV
这可以帮助您使用javascript阅读您的csv。您可以访问此链接,因为这与您的问题有些相关。 Evans Answer

使用jQuery,这将是一个简单的例子:
$('.dropbtn').click(function(){
$(this).siblings('.dropdown-content').toggleClass('hide');
});
使用以下CSS:
.dropdown-content{
position:absolute;
background:#000;
color:#fff;
}
.hide{
display:none;
}
我已经简化了您的HTML:
<p>
Hands-On with
<span class="dropdown">
<button type="button" class="dropbtn">Ultrahaptics'</button>
<a href="#home" class="dropdown-content hide">Feel of touch without wearing devices</a>

您可能也有兴趣使用the dfn
tag,但这会让您的HTML看起来有点不同。
