检查互联网是否使用 JavaScript/HTML 发送/接收数据包
我一直在编写一些 HTML 代码来告诉我互联网的状态，我设置了离线和在线事件，但我想检查我的互联网是否正在发送或接收数据包。我该如何使用 JavaScript 来做到这一点？我检查了所有地方，但我不知道如何在 JavaScript 中做到这一点。 （预先感谢！）
这是我的代码：
<!DOCTYPE html>
<html>
<body onoffline="myFunction(); myFunction12();" ononline="myFunction1(); myFunction02();"
onpacketsend="myFunction2(); setTimeout(() => {myFunction22}, 300);">
<h3 id="demo1">Online.</h3>
<h3 id="demo2">Sending/Recieving...</h3>
<h3 id="demo">Offline!</h3>
<script>
function myFunction() {
document.getElementById("demo").style.color = "red";
}
function myFunction1() {
document.getElementById("demo1").style.color = "green";
}
function myFunction2() {
document.getElementById("demo2").style.color = "blue";
}
function myFunction02() {
document.getElementById("demo").style.color = "black";
}
function myFunction12() {
document.getElementById("demo1").style.color = "black";
}
function myFunction22() {
document.getElementById("demo2").style.color = "black";
}
</script>
</body>
</html>
I have been making some HTML code to tell me the status of my internet, I have offline and online events set up but I want to check if my internet's sending or receiving packets. How would I do this using JavaScript? I checked everywhere but I can't figure out how to do this in JavaScript. (Thanks in advance!)
Here's my code:
<!DOCTYPE html>
<html>
<body onoffline="myFunction(); myFunction12();" ononline="myFunction1(); myFunction02();"
onpacketsend="myFunction2(); setTimeout(() => {myFunction22}, 300);">
<h3 id="demo1">Online.</h3>
<h3 id="demo2">Sending/Recieving...</h3>
<h3 id="demo">Offline!</h3>
<script>
function myFunction() {
document.getElementById("demo").style.color = "red";
}
function myFunction1() {
document.getElementById("demo1").style.color = "green";
}
function myFunction2() {
document.getElementById("demo2").style.color = "blue";
}
function myFunction02() {
document.getElementById("demo").style.color = "black";
}
function myFunction12() {
document.getElementById("demo1").style.color = "black";
}
function myFunction22() {
document.getElementById("demo2").style.color = "black";
}
</script>
</body>
</html>

目前无法使用 Javascript/HTML 进行操作。不幸的是，这意味着您只能检查是否已连接到互联网，
因此我只能：
It is not currently possible to do with Javascript/HTML. Unfortunatly this means you can only check to see if you are connected to the internet
so I can only:
