删除http://或http://和www

Question

嗨伙计们我正在努力建立一个网址清洁工.

我希望得到的URL列表,并删除所有https://,http://,www.从尾后的开始,也是所有文字,等等/.

我试过以下正则表达式 url.replace(/^https?\:\/\/www\./i, "").split('/')[0];

这在一定程度上起作用并输出以下内容

"www.net-temps.com"
"www.toplanguagejobs.com"
"http:"
"peopleready.com"
"nationjob.com"
"http:"
"bluesteps.com"
"https:"
"theguardian.com"
"reddit.com"
"youtube.com"
"https:"
"pgatour.com"
"cultofmac.com"

从以下列表:

'www.net-temps.com',
'www.toplanguagejobs.com',
'http://nychires.com/',
'http://www.peopleready.com/',
'https://www.nationjob.com/',
'http://nationaljobsonline.com/',
'https://www.bluesteps.com/',

'http://www.cultofmac.com/464645/apple-spaceship-campus-flyover/'

如果我/www\.从正则表达式中删除它,这很好用,并删除所有https:等,但我也想删除www.它,如果它在那里,不管https:

这是我到目前为止编码的内容

将来,这将被分类.我想从文本区域运行makeDomainBeautiful并输出到另一个textarea 的URL列表,但我想我会先使用它.

/^(?:https?:\/\/)?(?:www\.)?/i其中https://和www.应该是optional(?)和非捕获组((?:...)).

var url = prompt("url: ");

url = url.replace(/^(?:https?:\/\/)?(?:www\.)?/i, "").split('/')[0];

alert("url: " + url);
