【问题描述】：
我正在使用 Bootstrap，并从 W3Schools 获取可过滤 div 元素的 JavaScript 代码。这是一种易于过滤的模式，但没有动画有点无聊。
因此，我试图在我的过滤器代码中通过 CSS 或 js 添加一些动画，但我不知道如何运行它。我尝试了 CSS 和 js 动画，但没有，它不起作用。
HTML
<div class="container-fluid">
<div id="myBtnContainer">
<ul>
<li class="list-inline-item"><button class="btn active" onclick="filterSelection('all')">All</button></li>
<li class="list-inline-item"><button class="btn" onclick="filterSelection('category1')">Category1</button></li>
<li class="list-inline-item"><button class="btn" onclick="filterSelection('category2')">Category2</button></li>
</ul>
</div>
<div class="row row-cols-1 row-cols-sm-2 row-cols-lg-3 g-3 pt-2 pb-5">
<div class="col fade-in-image filterDiv category1 show">
<a href="http://localhost:8888/test01/projects/project1/">
<div class="card">
<img width="480" height="320" src="http://localhost:8888/test01/wp-content/uploads/2021/06/img1.jpeg" class="img-fluid wp-post-image" alt="" loading="lazy">
<div class="hover-project">
<h3 class="titol-projecte">Project 1</h3>
<p class="location pb-4">Location 1</p>
<p class="category">Category 1</p>
</div>
</div>
</a>
</div>
<div class="col fade-in-image filterDiv category-2 show">
<a href="http://localhost:8888/test01/projects/project2/">
<div class="card">
<img width="480" height="320" src="http://localhost:8888/test01/wp-content/uploads/2021/06/img2.jpeg" class="img-fluid wp-post-image" alt="" loading="lazy">
<div class="hover-project">
<h3 class="titol-projecte">Project 2</h3>
<p class="location pb-4">Location 2</p>
<p class="category">Category 2</p>
</div>
</div>
</a>
</div>
</div>
</div>
我使用的 JavaScript：
filterSelection("all")
function filterSelection(c) {
var x, i;
x = document.getElementsByClassName("filterDiv");
if (c == "all") c = "";
// Add the "show" class (display:block) to the filtered elements, and remove the "show" class from the elements that are not selected
for (i = 0; i < x.length; i++) {
w3RemoveClass(x[i], "show");
if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
}
}
// Show filtered elements
function w3AddClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
if (arr1.indexOf(arr2[i]) == -1) {
element.className += " " + arr2[i];
}
}
}
// Hide elements that are not selected
function w3RemoveClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
while (arr1.indexOf(arr2[i]) > -1) {
arr1.splice(arr1.indexOf(arr2[i]), 1);
}
}
element.className = arr1.join(" ");
}
// Add active class to the current control button (highlight it)
var btnContainer = document.getElementById("myBtnContainer");
var btns = btnContainer.getElementsByClassName("btn");
for (var i = 0; i < btns.length; i++) {
btns[i].addEventListener("click", function() {
var current = document.getElementsByClassName("active");
current[0].className = current[0].className.replace(" active", "");
this.className += " active";
});
}
我使用的 CSS
.filterDiv {
display: none; /* Hidden by default */
visibility: hidden;
opacity: 0;
}
/* The "show" class is added to the filtered elements */
.show {
display: block;
visibility: visible;
opacity: 1;
}
谢谢！！
【问题讨论】：
-
如果您使用 CSS 样式“隐藏”，则无法为元素设置动画。 （仅供参考）
-
@hamid 如果我不使用溢出隐藏，我该如何解决？
-
我的意思是如果你改变了元素的显示不显示/可见，你不能使用过渡。
