Get the domain and page name from a String URL
提问by Sindar
Well i'm currently have some issue about manipulating an URL.
好吧，我目前在操作 URL 方面遇到了一些问题。
Technically what i want is to get the domain name and the page name from a page.
从技术上讲，我想要的是从页面中获取域名和页面名称。
For example :
例如 ：
www.myWebSite.com => domain : myWebSite
http://myWebSite.com => domain : myWebSite
myWebSite.com/xxx.hmtl => domain : myWebSite page : xxx

window.location.hostname; //Domain name
$("title").text(); //Page name
EDIT:
编辑：
var loc = window.location;
var filename = loc.pathname.split("/");
filename = filename[pathname.length-1];
alert("Domain: "+loc.hostname);
alert("Filename: "+filename);

try with url.match(/:\/\/(.[^/]+)/)[1]
尝试 url.match(/:\/\/(.[^/]+)/)[1]
example :
例子 ：
var r = /:\/\/(.[^/]+)/;
"http://stackoverflow.com/questions/5343288/get-the-domain-and-page-name-from-a-string-url".match(r)[1]

Use window.location.hostnameor window.location.host. Check location reference.
使用window.location.hostname或window.location.host。检查位置参考。

我希望这有帮助：
function breakDownURL(url) {
var domain = "",
page = "";
//remove "http://"
if (url.indexOf("http://") == 0) {
url = url.substr(7);
}
//remove "www."
if (url.indexOf("www.") == 0) {
url = url.substr(4);
}
domain = url.split('/')[0].split('.')[0]
if (url.split('/').length > 1) {
page = url.split('/')[1].split('.')[0];
}
document.write("domain : " + domain +
(page == "" ? "" : " page : " + page) + page + "<br/>");
}
breakDownURL("www.myWebSite.com"); // domain : myWebSite
breakDownURL("http://myWebSite.com"); // domain : myWebSite
breakDownURL("myWebSite.com/xxx.html"); // domain : myWebSite page : xxx

var url = window.location.href; //www.myWebSite.com/myWebSite
var arr = url.split("/");
var page = arr[arr.length-1];
var domain = window.location.host;
alert(domain); //www.myWebSite.com
var n = page.includes("?"); // if www.myWebSite.com/myWebSite?parameter
if(n)
{
var page_arr = page.split("?");
var page = page_arr[0]; //myWebSite
}
alert(page); //myWebSite
