我想通过IE浏览器获取本地计算机ip。机器未连接到互联网。以下代码可在Firefox和Google Chrome中正常运行，但不适用于IE [我只需要使用IE浏览器]。还有其他方法可以完成任务吗？
如果您有编码示例，对其他人也将有用。
可与Google Chrome和FireFox一起使用的示例。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Local IP</title>
<script>
var RTCPeerConnection =/* window.RTCPeerConnection || */ window.webkitRTCPeerConnection || window.mozRTCPeerConnection;
if (RTCPeerConnection)(function() {
var rtc = new RTCPeerConnection({
iceServers: []
});
if (1 || window.mozRTCPeerConnection) {
rtc.createDataChannel('',{
reliable: false
});
};
rtc.onicecandidate = function(evt) {
if (evt.candidate) grepSDP("a=" + evt.candidate.candidate);
};
rtc.createOffer(function(offerDesc) {
grepSDP(offerDesc.sdp);
rtc.setLocalDescription(offerDesc);
},function(e) {
console.warn("offer failed",e);
});
var addrs = Object.create(null);
addrs["0.0.0.0"] = false;
function updateDisplay(newAddr) {
if (newAddr in addrs) return;
else addrs[newAddr] = true;
var displayAddrs = Object.keys(addrs).filter(function(k) {
return addrs[k];
});
document.getElementById('list').textContent = displayAddrs.join(" or perhaps ") || "n/a";
}function grepSDP(sdp) {
var hosts = [];
sdp.split('\r\n').forEach(function(line) {
if (~line.indexOf("a=candidate")) {
var parts = line.split(' '),addr = parts[4],type = parts[7];
if (type === 'host') updateDisplay(addr);
} else if (~line.indexOf("c=")) {
var parts = line.split(' '),addr = parts[2];
updateDisplay(addr);
}
});
}
})();
else {
document.getElementById('list').innerHTML = "<code>ifconfig| grep inet | grep -v inet6 | cut -d\" \" -f2 | tail -n1</code>";
document.getElementById('list').nextSibling.textContent = "In Chrome and Firefox your IP should display automatically,by the power of WebRTCskull.";
}
