A regex solution would be cool.
正则表达式解决方案会很酷。
The following sample only gets the domain name:
以下示例仅获取域名：
var url = $(location).attr('href');
alert(get_domain(url));
function get_domain(url) {
return url.match(/http:\/\/.*?\//);

var url = "http://www.mysite.com/username_here801";
var username = url.match(/username_(.+)/)[1];
To always return the text directly after the slash that follows the .com you can do this:
要始终在 .com 后面的斜杠之后直接返回文本，您可以执行以下操作：
var url = "http://www.mysite.com/username_here801";
var urlsplit = url.split("/");
var username = urlsplit[3];

If a RegEx solution is acceptable, you could try:
如果可以接受 RegEx 解决方案，您可以尝试：
function get_path(url) {
// following regex extracts the path from URL
return url.replace(/^https?:\/\/[^\/]+\//i, "").replace(/\/$/, "");
}

You could use your getDomain() function to find out where your pathname start.:
您可以使用 getDomain() 函数找出路径名的开始位置。：
function getUsername(url){
var position = getDomain(url).length + 1;
return url.slice(position);
}
