className={style.input} 不起效果

可能是几个原因导致的:
1. 检查一下你的 `style` 对象是否正确导入,路径是否正确。
2. 确认一下 `className` 是否被正确地传递到 `input` 元素上。
3. 检查一下 `style` 对象中是否包含了名为 `input` 的 CSS 类名,且其样式是否正确定义。
4. 如果你是使用 CSS Modules,可能需要将 `style.input` 改成 `style['input']`。
希望以上几点可以帮到你找到问题所在。

这段代码需要放在 `<script>` 标签中,并且需要放在HTML文件的 `<body>` 标签的末尾,确保页面其他元素都已加载完毕。通常情况下,它可以放在 `<body>` 标签的底部,就像这样:
```
<!DOCTYPE html>

<head>
<meta charset="UTF-8">
<title>My Website</title>
<link rel="stylesheet" href="style.css">

<body>
<!-- 这里是页面的主要内容 -->
<div id="chatbot">
<div id="chat-header">

<button id="chat-close">×</button>
</div>
<div id="chat-body">
<div id="chat-messages">
<div class="message received">您好,有什么可以帮您的吗?</div>
</div>
<div id="chat-input">
<input type="text" placeholder="请输入您的问题">
<button id="chat-send">发送</button>
</div>
</div>
</div>

// 获取页面元素
const chatbot = document.getElementById('chatbot');
const chatHeader = document.getElementById('chat-header');
const chatClose = document.getElementById('chat-close');
const chatMessages = document.getElementById('chat-messages');
const chatInput = document.getElementById('chat-input');
const chatInputBox = document.querySelector('#chat-input input');
const chatSend = document.getElementById('chat-send');
// 客服自动回复
function chatbotReply(message) {
const reply = '这是客服自动回复的消息:' + message;
const received = document.createElement('div');
received.className = 'message received';
received.textContent = reply;
chatMessages.appendChild(received);
chatMessages.scrollTop = chatMessages.scrollHeight;
}
// 用户发送消息
function sendMessage() {
const message = chatInputBox.value;
if (!message) {
return;
}
const sent = document.createElement('div');
sent.className = 'message sent';
sent.textContent = message;
chatMessages.appendChild(sent);
chatMessages.scrollTop = chatMessages.scrollHeight;
chatInputBox.value = '';
chatbotReply(message);
}
// 关闭客服窗口
chatClose.addEventListener('click', function() {
chatbot.style.display = 'none';
});
// 发送消息
chatSend.addEventListener('click', function() {

});
chatInputBox.addEventListener('keydown', function(event) {
if (event.key === 'Enter') {

}
});

window.addEventListener('load', function() {

function previewImage(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { var img = document.createElement("img"); img.src = e.target.result; img.alt = "照片"; img.onclick = function () { showPopup(img.src); }; // 隐藏原始的input元素 input.style.display = "none"; // 添加图片到input元素的父节点 input.parentNode.appendChild(img); }; reader.readAsDataURL(input.files[0]); } } function showPopup(imageSrc) { var popup = document.createElement("div"); var popupImg = document.createElement("img"); var scale = 1; var isDragging = false; var startX, startY, translateX, translateY;
这段代码是用来预览和放大图片的。`previewImage` 函数用于选择图片文件后预览它,并将其添加到对应的输入框之外。`showPopup` 函数用于在单击预览图片时显示一个弹出窗口,并允许对图片进行缩放和拖动操作。
下面是完整的代码示例:
```javascript
function previewImage(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
var img = document.createElement("img");
img.src = e.target.result;
img.alt = "照片";
img.onclick = function () {
showPopup(img.src);
};
// 隐藏原始的 input 元素
input.style.display = "none";
// 添加图片到 input 元素的父节点
input.parentNode.appendChild(img);
};
reader.readAsDataURL(input.files[0]);
}
}
function showPopup(imageSrc) {
var popup = document.createElement("div");
var popupImg = document.createElement("img");
var scale = 1;
var isDragging = false;
var startX, startY, translateX, translateY;
popup.className = "popup";
popup.onclick = function () {
document.body.removeChild(popup);
};
popupImg.src = imageSrc;
popupImg.className = "popup-image";
popupImg.onmousedown = function (e) {
isDragging = true;
startX = e.clientX;
startY = e.clientY;
translateX = 0;
translateY = 0;
};
popupImg.onmousemove = function (e) {
if (isDragging) {
var deltaX = e.clientX - startX;
var deltaY = e.clientY - startY;
translateX += deltaX;
translateY += deltaY;
startX = e.clientX;
startY = e.clientY;
popupImg.style.transform = `translate(${translateX}px, ${translateY}px) scale(${scale})`;
}
};
popupImg.onmouseup = function () {
isDragging = false;
};
popupImg.onwheel = function (e) {
e.preventDefault();
var delta = Math.max(-1, Math.min(1, e.deltaY));
scale += delta * 0.1;
scale = Math.max(0.1, scale);
popupImg.style.transform = `translate(${translateX}px, ${translateY}px) scale(${scale})`;
};
popup.appendChild(popupImg);
document.body.appendChild(popup);
}
```
请确保在 HTML 文件中正确引入相关的 CSS 样式,这样弹出窗口和图片的显示效果才能正常展示。
