好的,以下是一个基本的滑动验证的代码示例:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>滑动验证</title>
<style>
#slider {
position: relative;
width: 300px;
height: 40px;
background-color: #ccc;
border-radius: 20px;
margin: 50px auto;
}
#slider .slider-handle {
position: absolute;
top: 0;
left: 0;
width: 40px;
height: 40px;
border-radius: 50%;
background-color: #fff;
box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
cursor: pointer;
transition: all 0.3s ease-in-out;
}
#slider .slider-track {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #4CAF50;
border-radius: 20px;
transition: all 0.3s ease-in-out;
}
#slider.dragging .slider-handle {
box-shadow: 0 0 5px rgba(0, 0, 0, 0.4);
}
#slider.dragging .slider-track {
opacity: 0.5;
}
#slider.complete .slider-handle {
background-color: #4CAF50;
color: #fff;
}
#slider.complete .slider-track {
background-color: #fff;
}
#slider.complete .slider-handle:before {
content: "√";
}
</style>
</head>
<body>
<div id="slider">
<div class="slider-handle"></div>
<div class="slider-track"></div>
</div>
<script>
var slider = document.querySelector("#slider");
var handle = slider.querySelector(".slider-handle");
var track = slider.querySelector(".slider-track");
var isDragging = false;
var isComplete = false;
var startOffset = 0;
var endOffset = slider.offsetWidth - handle.offsetWidth;
handle.addEventListener("mousedown", function(event) {
isDragging = true;
startOffset = event.clientX - handle.offsetLeft;
slider.classList.add("dragging");
});
document.addEventListener("mousemove", function(event) {
if (isDragging) {
var newOffset = event.clientX - startOffset;
if (newOffset < 0) {
newOffset = 0;
} else if (newOffset > endOffset) {
newOffset = endOffset;
}
handle.style.left = newOffset + "px";
track.style.width = newOffset + "px";
}
});
document.addEventListener("mouseup", function() {
if (isDragging) {
isDragging = false;
if (parseInt(handle.style.left) === endOffset) {
isComplete = true;
slider.classList.add("complete");
} else {
handle.style.left = 0;
track.style.width = 0;
}
slider.classList.remove("dragging");
}
});
</script>
</body>
</html>
```
以上代码使用了 HTML、CSS 和 JavaScript 来实现一个简单的滑动验证。你可以将这段代码复制到 Visual Studio Code 中,然后保存为 HTML 文件,用浏览器打开即可看到效果。
