我制作了这个html和jscript下拉按钮但是当我尝试添加更多按钮时,下拉菜单中的链接仅适用于一个按钮,并且在与第一个按钮相同的链接中更改另外两个按钮。
例如,如果第一个按钮在下拉列表'#ro'的内容中有一个链接,而另外两个按钮有'#en'和'#de',它将为所有人显示'#ro'。
如何解决此问题并为所有按钮创建单独的链接? 这是我的代码
/* When the user clicks on the button,
toggle between hiding and showing 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');
}
}
}
}
.hide {
display:none;
}
.visible {
display:block;
}
.dropbtn {
background-color: #602121;
color: white;
padding: 2px;
font-size: 10px;
border: none;
cursor: pointer;
}
.dropbtn:hover, .dropbtn:focus {
background-color: #3e8e41;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 60px;
overflow: auto;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
.dropdown-content a {
color: black;
padding: 2px 2px;
text-decoration: none;
display: block;
}
.dropdown a:hover {background-color: #f1f1f1}
.show {display:block;}
