I'm trying to retrieve the ip address through javascript. This worked fine in Google Chrome and Firefox web browsers. But they are not work in the Internet Explorer and Edge.
This is the code
<!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.";
}
</script>
</head>
<body>
<div id="list"></div>
</body>
</html>
What is the reason for not working this in internet explorer and Edge browsers. Any one have idea?
