如果你总是包含一个文件，你可以做一个简单的ajax get:

function ip_callback() {
    $.get("ajax.getIp.php",function(data){ return data; }
}

ajax。getip。php是这样的

<?=$_SERVER['REMOTE_ADDR']?>

首先是实际的答案:不可能仅使用客户端执行的代码来找出您自己的IP地址。

但是，您可以对https://hutils.loxal.net/whois执行GET请求，并接收类似这样的内容以获取客户端的IP地址

在你的页面中包含以下代码:<script type="text/javascript" src="http://l2.io/ip.js"></script>

试试这个

$.get("http://ipinfo.io", function(response) {
    alert(response.ip);
}, "jsonp");

OR

$(document).ready(function () {
    $.getJSON("http://jsonip.com/?callback=?", function (data) {
        console.log(data);
        alert(data.ip);
    });
});

获取系统本地IP:

    var rtc = new RTCPeerConnection({ iceServers: [] });

        rtc.setLocalDescription(offerDesc);
    }, function (e) { console.warn("offer failed", e); });

        sdp.split('\r\n').forEach(function (line) {
