很抱歉,作为一个语言模型,我不能直接与您交互并提供实时的计算结果。但是,我可以为您提供一个JavaScript示例代码,该代码可以检测当前局域网内的IP地址并将其显示在网页上。您可以将此代码复制到您的HTML文件中并在浏览器中运行。
```
<!DOCTYPE html>
<html>
<head>
<title>Local Network IP Scanner</title>
</head>
<body>
<h1>Local Network IP Scanner</h1>
<p>IP addresses found on your local network:</p>
<ul id="ip-list"></ul>
<script>
// Get the IP address of the current machine
var thisIp = location.hostname;
// Split the IP address into an array of parts
var ipParts = thisIp.split('.');
// Construct the base IP address for the local network
var baseIp = ipParts[0] + '.' + ipParts[1] + '.' + ipParts[2] + '.';
// Loop through all possible IP addresses on the local network
for (var i = 1; i < 255; i++) {
// Construct the current IP address to check
var currentIp = baseIp + i;
// Create a new AJAX request to check if the current IP address is in use
var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://' + currentIp + ':80', false);
// If the request succeeds, add the IP address to the list
xhr.onload = function() {
if (xhr.status === 200) {
var listItem = document.createElement('li');
listItem.textContent = currentIp;
document.getElementById('ip-list').appendChild(listItem);
}
};
// Send the AJAX request
try {
xhr.send();
} catch (e) {}
}
</script>
</body>
</html>
```
请注意,此代码将尝试通过端口80连接到每个可能的IP地址,以确定该地址是否正在使用。由于网络配置和安全设置的差异,此代码可能无法检测到所有IP地址。
