我目前正在我的网站上工作,根据访问者的国家/地区显示各种地方。
我也试过这个例子,但我想自动获取IP地址
这里是示例代码
HTML
<input type="text" id="ip" />
<input type="button" value="Get country of IP" id="submit" />
的JavaScript
<script type="text/javascript">
$(function() {
$("#submit").click(function() {
if ($('#ip').val()) {
var ip = $('#ip').val();
// the request will be to http://www.geoplugin.net/json.gp?ip=my.ip.number but we need to avoid the cors issue, and we use cors-anywhere api.
$.getJSON("https://cors-anywhere.herokuapp.com/http://www.geoplugin.net/json.gp?ip=" + ip, function(response) {
console.log(response);
// output an object which contains the information.
$("#content").html("Hello visitor from " + response.geoplugin_countryName);
});
} else {
alert("Please provide a IP");
}
});
});
</script>
我是PHP的新手,所以请指导我..谢谢:)

尝试以下代码
let a = new Array(3);
a.join('.').split('.').map(v => 1);
let a = new Array(3);
a.fill(1);
let a = new Array(3);
a.fill(undefined).map(v => 1);
let a = new Array(3);
[...a].map(v => 1);
// Jquery
$.getJSON("http://freegeoip.net/json/", function(data) {
var ip = data.ip;
var country = data.country_name;
$("#ip").val(ip);
$("#content").html("Hello visitor from " + country);
});
